2Work area safetyKeep work area clean and well lit. Clutteredor dark areas invite accidents.

Do not operate power tools in explosiveatmospheres, such as in the presence offlammable liquids, gases or dust. Powertools create sparks which may ignite the dustor fumes.

Keep children and bystanders away whileoperating a power tool. Distractions cancause you to lose control.

Electrical safetyPower tool plugs must match the outlet.Never modify the plug in any way. Do notuse any adapter plugs with earthed(grounded) power tools. Unmodified plugsand matching outlets will reduce risk of electricshock.

Avoid body contact with earthed or groundedsurfaces such as pipes, radiators, rangesand refrigerators. There is an increased riskof electric shock if your body is earthed orgrounded.

Do not expose power tools to rain or wetconditions. Water entering a power tool willincrease the risk of electric shock.

Do not abuse the cord. Never use the cordfor carrying, pulling or unplugging the powertool. Keep cord away from heat, oil, sharpedges or moving parts. Damaged or entangledcords increase the risk of electric shock.

When operating a power tool outdoors,use an extension cord suitable for outdooruse. Use of a cord suitable for outdoor usereduces the risk of electric shock.

If operating the power tool in damp locationsis unavoidable, use a Ground Fault CircuitInterrupter (GFCI) protected supply. Use ofan GFCI reduces the risk of electric shock.

Personal safetyStay alert, watch what you are doing anduse common sense when operating a

power tool. Do not use a power tool whileyou are tired or under the influence of drugs,alcohol or medication. A moment of inattentionwhile operating power tools may result inserious personal injury.

Use personal protective equipment. Alwayswear eye protection. Protective equipmentsuch as dust mask, non-skid safety shoes, hardhat, or hearing protection used for appropriateconditions will reduce personal injuries.

Prevent unintentional starting. Ensure theswitch is in the off-position beforeconnecting to power source and / or batterypack, picking up or carrying the tool.Carrying power tools with your finger on theswitch or energizing power tools that have theswitch on invites accidents.

Remove any adjusting key or wrench beforeturning the power tool on. A wrench or a keyleft attached to a rotating part of the powertool may result in personal injury.

Do not overreach. Keep proper footing andbalance at all times. This enables bettercontrol of the power tool in unexpectedsituations.

Dress properly. Do not wear loose clothingor jewelry. Keep your hair, clothing andgloves away from moving parts. Looseclothes, jewelry or long hair can be caught inmoving parts.

If devices are provided for the connectionof dust extraction and collection facilities,ensure these are connected and properlyused. Use of dust collection can reduce dust-related hazards.

Power tool use and careDo not force the power tool. Use the correctpower tool for your application. The correctpower tool will do the job better and safer atthe rate for which it was designed.

Do not use the power tool if the switch doesnot turn it on and off. Any power tool thatcannot be controlled with the switch isdangerous and must be repaired.

Read all safety warnings and all instructions. Failure to follow the warningsand instructions may result in electric shock, fire and/or serious injury.

3Disconnect the plug from the power sourceand/or the battery pack from the power toolbefore making any adjustments, changingaccessories, or storing power tools. Suchpreventive safety measures reduce the risk ofstarting the power tool accidentally.

Store idle power tools out of the reach ofchildren and do not allow persons unfamiliarwith the power tool or these instructions tooperate the power tool. Power tools aredangerous in the hands of untrained users.

Maintain power tools. Check for misalignmentor binding of moving parts, breakage ofparts and any other condition that mayaffect the power tools operation. If damaged,have the power tool repaired before use.Many accidents are caused by poorlymaintained power tools.

Keep cutting tools sharp and clean. Properlymaintained cutting tools with sharp cuttingedges are less likely to bind and are easier tocontrol.

Use the power tool, accessories and toolbits etc. in accordance with these instructions,taking into account the working conditionsand the work to be performed. Use of thepower tool for operations different from thoseintended could result in a hazardous situation.

Battery tool use and careRecharge only with the charger specifiedby the manufacturer. A charger that issuitable for one type of battery pack maycreate a risk of fire when used with anotherbattery pack.

Use power tools only with specificallydesignated battery packs. Use of any otherbattery packs may create a risk of injury andfire.

When battery pack is not in use, keep itaway from other metal objects like paperclips, coins, keys, nails, screws, or othersmall metal objects that can make aconnection from one terminal to another.Shorting the battery terminals together maycause burns or a fire.

Under abusive conditions, liquid may beejected from the battery, avoid contact. Ifcontact accidentally occurs, flush withwater. If liquid contacts eyes, additionallyseek medical help. Liquid ejected from thebattery may cause irritation or burns.

Safety Rules for Rotary Tools

Safety warnings common forgrinding, sanding, wire brushing,

polishing, carving or abrasivecutting-off operations:

This power tool is intended to function as agrinder, sander, wire brush, polisher,carving or cut-off tool. Read all safetywarnings, instructions, illustrations andspecifications provided with this powertool. Failure to follow all instructions listedbelow may result in electric shock, fire and/orserious injury.

Do not use accessories which are notspecifically designed and recommended bythe tool manufacturer. Just because theaccessory can be attached to your power tool,it does not assure safe operation.

The rated speed of the accessory must beat least equal to the operating speedsetting marked on the power tool.Accessories running faster than their RATEDSPEED can break and fly apart.

The outside diameter and the thickness ofyour accessory must be within the capacityrating of your power tool. Incorrectly sizedaccessories cannot be adequately guarded orcontrolled.

The arbor size of wheels, sanding drums orany other accessory must properly fit thespindle or collet of the power tool.Accessories that do not match the mountinghardware of the power tool will run out ofbalance, vibrate excessively and may causeloss of control.

Mandrel mounted wheels, sanding drums,cutters or other accessories must be fullyinserted into the collet or chuck. If themandrel is insufficiently held and/or theoverhang of the wheel is too long, the mountedwheel may become loose and be ejected athigh velocity.

Do not use a damaged accessory. Beforeeach use inspect the accessory such asabrasive wheels for chips and cracks,

4Safety Rules for Rotary Tools - (cont.)

sanding drum for cracks, tear or excesswear, wire brush for loose or cracked wires.If power tool or accessory is dropped,inspect for damage or install an undamagedaccessory. After inspecting and installingan accessory, position yourself andbystanders away from the plane of the rotating accessory and run the power toolat maximum no-load speed for one minute.Damaged accessories will normally break apartduring this test time.

Wear personal protective equipment.Depending on application, use face shield,safety goggles or safety glasses. Asappropriate, wear dust mask, hearingprotectors, gloves and workshop aproncapable of stopping small abrasive orworkpiece fragments. The eye protectionmust be capable of stopping flying debrisgenerated by various operations. The dustmask or respirator must be capable of filtratingparticles generated by your operation.Prolonged exposure to high intensity noise maycause hearing loss.

Keep bystanders a safe distance away fromwork area. Anyone entering the work areamust wear personal protective equipment.Fragments of workpiece or of a brokenaccessory may fly away and cause injurybeyond immediate area of operation.

Hold power tool by insulated grippingsurfaces only, when performing anoperation where the cutting accessory maycontact hidden wiring. Cutting accessorycontacting a live wire may make exposedmetal parts of the power tool live and couldgive the operator an electric shock.

Always hold the tool firmly in your hand(s)during the start-up. The reaction torque of themotor, as it accelerates to full speed, can causethe tool to twist.

Use clamps to support workpiece wheneverpractical. Never hold a small workpiece inone hand and the tool in the other handwhile in use. Clamping a small workpieceallows you to use your hand(s) to control thetool. Round material such as dowel rods, pipesor tubing have a tendency to roll while beingcut, and may cause the bit to bind or jumptoward you.

Position the cord clear of the spinningaccessory. If you lose control, the cord may becut or snagged and your hand or arm may bepulled into the spinning accessory.

Never lay the power tool down until theaccessory has come to a complete stop.The spinning accessory may grab the surfaceand pull the power tool out of your control.

After changing the bits or making anyadjustments, make sure the collet nut,chuck or any other adjustment devices aresecurely tightened. Loose adjustment devicescan unexpectedly shift, causing loss of control,loose rotating components will be violentlythrown.

Do not run the power tool while carrying itat your side. Accidental contact with thespinning accessory could snag your clothing,pulling the accessory into your body.

Regularly clean the power tools air vents.The motors fan will draw the dust inside thehousing and excessive accumulation ofpowdered metal may cause electrical hazards.

Do not operate the power tool nearflammable materials. Sparks could ignitethese materials.

Do not use accessories that require liquidcoolants. Using water or other liquid coolantsmay result in electrocution or shock.

Kickback and Related WarningsKickback is a sudden reaction to a pinched orsnagged rotating wheel, backing pad, brush orany other accessory. Pinching or snaggingcauses rapid stalling of the rotating accessorywhich in turn causes the uncontrolled powertool to be forced in the direction opposite of theaccessorys rotation.

For example, if an abrasive wheel is snaggedor pinched by the workpiece, the edge of thewheel that is entering into the pinch point candig into the surface of the material causing thewheel to climb out or kickout. The wheel mayeither jump toward or away from the operator,depending on direction of the wheelsmovement at the point of pinching. Abrasivewheels may also break under these conditions.

Kickback is the result of power tool misuseand/or incorrect operating procedures orconditions and can be avoided by taking properprecautions as given below.

Safety Rules for Rotary Tools - (cont.)

Maintain a firm grip on the power tool andposition your body and arm to allow you toresist kickback forces. The operator cancontrol torque reactions or kickback forces, ifproper precautions are taken.

Use special care when working corners,sharp edges etc. Avoid bouncing andsnagging the accessory. Corners, sharpedges or bouncing have a tendency to snag therotating accessory and cause loss of control orkickback.

Do not attach a toothed saw blade. Suchblades create frequent kickback and loss ofcontrol.

Always feed the bit into the material in thesame direction as the cutting edge is exitingfrom the material (which is the samedirection as the chips are thrown). Feedingthe tool in the wrong direction causes thecutting edge of the bit to climb out of the workand pull the tool in the direction of this feed.

When using rotary files, cut-off wheels,high-speed cutters or tungsten carbidecutters, always have the work securelyclamped. These wheels will grab if theybecome slightly canted in the groove, and cankickback. When a cut-off wheel grabs, thewheel itself usually breaks. When a rotary file,high-speed cutter or tungsten carbide cuttergrabs, it may jump from the groove and youcould lose control of the tool.

Safety warnings specific for grindingand abrasive cutting-off operations:

Use only wheel types that arerecommended for your power tool and onlyfor recommended applications. Forexample: do not grind with the side of a cut-off wheel. Abrasive cut-off wheels are intendedfor peripheral grinding, side forces applied tothese wheels may cause them to shatter.

For threaded abrasive cones and plugs useonly undamaged wheel mandrels with anunrelieved shoulder flange that are ofcorrect size and length. Proper mandrels willreduce the possibility of breakage.

Do not jam a cut-off wheel or applyexcessive pressure. Do not attempt to makean excessive depth of cut. Overstressing thewheel increases the loading and susceptibilityto twisting or snagging of the wheel in the cutand the possibility of kickback or wheelbreakage.

Do not position your hand in line with andbehind the rotating wheel. When the wheel,at the point of operation, is moving away fromyour hand, the possible kickback may propelthe spinning wheel and the power tool directlyat you.

When wheel is pinched, snagged or wheninterrupting a cut for any reason, switch offthe power tool and hold the power toolmotionless until the wheel comes to acomplete stop. Never attempt to remove thecut-off wheel from the cut while the wheel isin motion otherwise kickback may occur.Investigate and take corrective action toeliminate the cause of wheel pinching orsnagging.

Do not restart the cutting operation in theworkpiece. Let the wheel reach full speedand carefully re-enter the cut. The wheel maybind, walk up or kickback if the power tool isrestarted in the workpiece.

Support panels or any oversized workpieceto minimize the risk of wheel pinching andkickback. Large workpieces tend to sag undertheir own weight. Supports must be placedunder the workpiece near the line of cut andnear the edge of the workpiece on both sides ofthe wheel.

Use extra caution when making a pocketcut into existing walls or other blind areas.The protruding wheel may cut gas or waterpipes, electrical wiring or objects that can causekickback.

Safety warnings specific for wirebrushing operations:

Be aware that wire bristles are thrown bythe brush even during ordinary operation.Do not overstress the wires by applyingexcessive load to the brush. The wire bristlescan easily penetrate light clothing and/or skin.

Allow brushes to run at operating speed forat least one minute before using them.During this time no one is to stand in frontor in line with the brush. Loose bristles orwires will be discharged during the run-in time.

Direct the discharge of the spinning wirebrush away from you. Small particles and tinywire fragments may be discharged at highvelocity during the use of these brushes andmay become imbedded in your skin.

COLLET NUTTo loosen the collet nut, first press shaft lockbutton and rotate the shaft by hand until thelock engages the shaft preventing furtherrotation. Your Dremel Micro is equipped witha shaft lock mechanism. This mechanismengages the output shaft in 2 separatelocations on the shaft for easier operation.

Do not engage lock whilethe Rotary Tool is running.

With the shaft lock engaged, use the colletwrench to loosen the collet nut if necessary.The collet nut must be loosely threaded onwhen inserting an accessory. Changeaccessories by inserting the new one into thecollet as far as possible to minimize runoutand unbalance. With the shaft lock engaged,finger t ighten the collet nut unti l theaccessory shank is gripped by the collet.Avoid excessive tightening of the colletnut when there is no bit inserted.

COLLETSFour different size collets (see illus tration), toaccommodate different shank sizes, areavail able for your Rotary Tool. To install adifferent collet, remove the collet nut andremove the old collet. Insert the unslottedend of the collet in the hole in the end of thetool shaft. Replace collet nut on the shaft.

Always use the colletwhich matches the shank

size of the accessory you plan to use.Never force a larger diameter shank into acollet.

Note: Most rotary tool kits do not include allfour collets sizes.

BALANCING ACCESSORIESFor precision work, it is important that allaccessories be in good balance (much thesame as the tires on your automobile). Totrue up or balance an accessory, slightlyloosen collet nut and give the accessory orcollet a 1/4 turn. Re tighten collet nut and runthe Rotary Tool. You should be able to tell bythe sound and feel if your accessory isrunning in balance. Continue adjusting in thisfashion until best balance is achieved. Tomaintain balance on abrasive wheel points,before each use, with the wheel point

secured in the collet, turn on the Rotary Tooland run the 415 Dressing Stone lightlyagainst the revolving wheel point. Thisremoves high spots and trues up the wheelpoint for good balance.

Brushing Pressure1. Remember, the tips of a wire brush do the

work. Operate the brush with the lightestpressure so only the tips of the wire comein contact with the work.

2. If heavier pressures are used, the wireswill be overstressed, resulting in a wipingaction; and if this is continued, the life of

the brush will be shortened due to wirefatigue.

3. Apply the brush to the work in such a waythat as much of the brush face as possibleis in full contact with the work. Applying theside or edge of the brush to the work willresult in wire breakage and shortenedbrush life.

INCORRECT:Excessive pressure can cause wire breakage.

CORRECT:Wire tips doing the work.

Polishing AccessoriesThese include an impregnated polishing pointand an impregnated polishing wheel forbringing metal sur faces to smooth finish; a feltpolishing tip and felt polish ing wheel, and clothpolishing wheel, all used for polishing plastics,metals, jewelry and small parts. Also includedin this group is a polishing compound (No. 421)for use with the felt and cloth polishers.

This product was designed by the manyDremel users who passionately use their rotarytools daily. The combination of design,ergonomics, and motor makes the DremelMicro highly user friendly and ideal for precisework and demanding tasks.

1-PreciseThe new Dremel tool is perfect for fine,detailed work where precision and control areneeded. The compact and ergonomic housingis designed for you to hold between yourthumb and forefinger so that the tool can becontrolled like a pencil. When held in thisposition you can hardly feel the lightweight andcompact tool in your hand! It is intended to bean extension of your hand and can be usedcomfortably for prolonged periods of timethanks also to the soft grip included in the frontend of the housing. The ultra slim body andtaper front-end allow you to grip the tool muchcloser to the work piece for a bettermaneuverability and control especially whenworking on intricate projects or in confined/tightareas.

Rotary Tool IntroductionThe Rotary Tool has a small, powerfulelectric motor, is comfort able in the hand,and is made to accept a large variety ofaccessories including abrasive wheels, drillbits, wire brushes, polishers, engravingcutters, cutting wheels. As you be comefamiliar with the range of accessories andtheir uses, you will learn just how versatilethe Rotary Tool is. Youll see dozens of usesyou hadnt thought of before.

The real secret of the Rotary Tool is itsspeed. To understand the advantages of itshigh speed, you have to know that thestandard portable electric drill runs at speedsup to 2,800 revolutions per minute. TheRotary Tool operates at speeds up to 28,000revolutions per minute. The typical electricdrill is a low-speed, high torque tool; theRotary Tool is just the opposite a high-speed, low torque tool. The major differenceto the user is that in the high speed tools, thespeed combined with the acces sory mountedin the collet does the work. You dont applypressure to the tool, but simply hold and

guide it. In the low speed tools, you not onlyguide the tool, but also apply pressure to it,as you do, for example, when drilling a hole.

It is this high speed, along with its compactsize and wide variety of special accessories,that makes the Rotary Tool differ ent from othertools. The speed enables it to do jobs lowspeed tools cannot do, such as cuttinghardened steel, en graving glass, etc.

Getting the most out of your Rotary Tool is amatter of learning how to let this speed workfor you. To learn about more uses and theversati l i ty of Dremel accessories andattachments refer to this Owner's Manual orcheck our website at www.Dremel.com.

Using the Rotary ToolThe first step in learning to use the RotaryTool is to get the feel of it. Hold it in yourhand and feel its weight and balance. Feelthe taper of the housing.

Always hold the toolaway from your face.Accessories can bedamaged duringhandling, and can flyapart as they come upto speed. This is not

common, but it does happen.

Whenever you hold the tool,be careful not to cover the

air vents with your hand. This blocks theair flow and causes the motor to overheat.

For best control in close work, grip the RotaryTool like a pencil between your thumb andforefinger (Figure 4).

The Golf Grip method of holding the toolcan be used for more aggressive operationssuch as grinding a flat surface or using cutoffwheels (Figure 5).

Practice on scrap materials first to see howthe Rotary Tool's high speed action performs.Keep in mind that the work is done by thespeed of the tool and by the accessory in thecollet. You should not lean on or push thetool during use.

Instead, lower the spinning accessory lightlyto the work and allow it to touch the point atwhich you want cutt ing (or sanding oretching, etc.) to begin. Con centrate onguiding the tool over the work using very littlepressure from your hand. Allow theaccessory to do the work.

Usually, it is best to make a series of passeswith the tool rather than attempt to do all thework in one pass. To make a cut, forexample, pass the tool back and forth overthe work, much as you would a small paintbrush. Cut a little material on each pass untilyou reach the desired depth. For most work,the gentle touch is best. With it, you have thebest control, are less likely to make errors,and will get the most effi cient work out of theaccessory.

TO TURN THE TOOL ON press andrelease the on/off blue button. The tool willstart working at a speed of 15,000 rpm andthe frontal LED light will turn on, If the on/offbutton is pressed but not released the tooland the frontal LED light wont turn on. Rightafter the tool is turned on you have thepossibility to turn off the frontal LED light.Simply press the minus () blue speedcontrol button 3 times and the frontal LEDlight will turn off. At this point the tool speedwill be set at 5,000 rpm. To turn on the frontalLED light again simply turn off and then onagain the tool.

TO TURN THE TOOL OFF press andrelease the on/off blue button. If for somereasons the on/off switch doesn't work thereis always the option to alternatively turn offthe tool by the following methods:

Press the minus () blue speed controlbutton to bring the speed of the tool to thelowest speed level (5,000 RPM).

Hold the minus () blue speed controlbutton for 5 seconds.

ELECTRONIC MONITORINGYour tool is equipped with an internalelectronic monitoring system that helps tomaximize motor and battery performance bylimiting the current to the tool when overloadand stall conditions occur. If you stall the toolfor too long, or bind the bit in a work piece,especially at high speeds, the tool wil lautomatically turn itself off thanks to thefallback built into it. Once this happens,simply take the tool out of the material youwere stalled in, turn it back on again, adjustthe speed if necessary, and continue using it.When the battery becomes close to empty,the tool may shut down automatically morefrequent than normal. If this happens, it istime to recharge the tool.

SPEED CONTROL BUTTONSYour Dremel Micro is equipped with speedcontrol buttons. The speed may be adjustedduring operation by pressing on the plus (+)or (-) minus blue buttons located on thetopside of the battery housing. Speed willincrement or decrement by 5,000 rpm from aminimum of 5,000 to a maximum of 28,000rpm. The LED lights located alongside theblue buttons will illuminate according to thechosen speed. Every time the tool is turnedoff the speed set goes back to the mediumlevel (15,000 rpm) so it might be necessaryto increase/decrease the speed to the levelthat it was being used (e.g. 28,000 rpm)before the tool was turned off to keepworking on the same application.

You can refer to the charts on pages 2730to determine the proper speed, based on thematerial being worked and the type ofaccessory being used. These charts enableyou to select both the correct accessory andthe optimum speed at a glance.

ServiceNO USER SERVICEABLEPARTS INSIDE. Preventive

maintenance performed by un au thorizedpersonnel may result in misplacing ofinternal wires and components whichcould cause serious hazard. We recom -mend that all tool service be performed by aDremel Service Center. SERVICE MEN:Disconnect tool and/or charger from powersource before servicing.

BATTERIESBe alert for batteries that are nearing theirend of life. If you notice decreased toolperformance or significantly shorter runningtime between charges then it is time toreplace the battery. Failure to do so cancause the tool to operate improperly ordamage the charger.

D.C. MOTORSThe motor in your tool has been engineeredfor many hours of dependable service. Tomaintain peak efficiency of the motor, werecommend it be examined every six months.Only a genuine Dremel replacement motorspecially designed for your tool should beused.

CleaningTo avoid accidents, alwaysbe sure the tool is turned

OFF before cleaning. The tool may becleaned most effectively with com pressed dryair. Always wear safety goggles whencleaning tools with compressed air.

Ventilation openings and switch levers mustbe kept clean and free of foreign matter. Donot attempt to clean by inserting pointedobjects through opening.

Certain cleaning agentsand solvents damage

plastic parts. Some of these are: gasoline,car bon tetrachloride, chlorinated cleaningsolvents, ammonia and household detergentsthat contain ammonia.

*15 is the maximum speed setting for wirebrushes.

Needs for Slower SpeedsCertain materials, however, (some plastics andprecious metals, for ex ample) require arelatively slow speed because at high speedthe friction of the accessory generates heatand may cause damage to the material.

Slow speeds (15,000 RPM or less) usually arebest for polishing operations employing the feltpolishing ac ces sories. They may also be bestfor working on deli cate projects as eggerywork, delicate wood carving and fragile modelparts. All brushing applications requirelower speeds to avoid wire discharge fromthe holder.

Higher speeds are better for carving, cutting,shaping, cutting dadoes or rabbets in wood.

Hardwoods, metals and glass require highspeed operation, and drilling should also bedone at high speeds.

Many applications and accessories in our linewill provide the best performance at full speed,but for certain materials, applications, andaccessories, you need slower speeds, which isthe reason our variable speed models areavailable.

To aid you in determining the optimumoperational speed for differ ent materials anddifferent accessories, we have construct ed aseries of tables that appear on page 23, 24, 25and 26. By referring to these tables, you candiscover the recommended speeds for eachtype of accessory. Look these tables over andbecome familiar with them.

Ultimately, the best way to determine thecorrect speed for work on any material is topractice for a few minutes on a piece of scrap,even after referring to the chart. You canquickly learn that a slower or faster speed ismore effective just by observing what hap pensas you make a pass or two at different speeds.When working with plastic, for example, startat a slow rate of speed and increase the speeduntil you observe that the plastic is melting atthe point of contact. Then reduce the speedslight ly to get the optimum working speed.

Some rules of thumb in regard to speed:

1. Plastic and other materials that melt at lowtemperatures should be cut at low speeds.

2. Polishing, buffing and cleaning with anytype of bristle brush must be done at speedsnot greater than 15,000 RPM to preventdamage to the brush from bristles flyingtoward operator.

3. Wood should be cut at high speed.

4. Iron or steel should be cut at high speed. Ifa high speed steel cutter starts to chatter this normally means it is running too slow.

5. Aluminum, copper alloys, lead alloys, zincalloys and tin may be cut at various speeds,depending on the type of cutting beingdone. Use paraffin or other suitablelubricant on the cutter to prevent the cutmaterial from adhering to the cutter teeth.

Increasing the pressure on the tool is not theanswer when it is not performing as you think itshould. Perhaps you should be using adifferent accessory, and perhaps anadjustment in speed would solve the problem.Leaning on the tool does not help.

Your Dremel Micro can be used with all of theDremel accessories, except router bits. Whilethe tool will work with cut-off wheels, thereduced speed of this tool will not allow themto perform optimally. They can be used to cutsoft materials such as wood or plastic, butcutting metals is not recommended. The Microtool cannot be used with any of the Dremel lineof attachments (attachments screw on to thenose of a rotary tool.)

Let speed do the work!

Use only Dremel, high-performance accessories.

887 3 HOUR 45 MINUTE CHARGERYour Dremel Micro does not come completelycharged from the factory. Be sure to chargetool prior to initial use. Plug the power adapterjack onto the charging base and insert thepower adapter plug into your standard poweroutlet. Place tool in charging base as shown infigure 7. The blue LED lights located on thetopside of the tool housing will start scrollingtop/down to signal the battery is receiving acharge. Charging will automatically stop whenthe tool is fully charged. When all the blue LEDlights are off charging is complete. At this pointthe battery charge light will be green. The toolmay be used even though the blue LED lightsmay still be scrolling top/down. The blue LEDlights might require more time to stop scrollingdepending on temperature.

The scope of the scrolling blue LED lights is toindicate that the tool is charging. It does notindicate the exact point of full charge. The blueLED lights will stop scrolling in less time if thetool was not completely discharged. In thiscase the battery charge light could be green,orange or red. When the battery pack is fullycharged you can leave the tool in the chargingbase.

Charging Tool

FUEL GAUGEThis tool is equipped with a fuel gauge thattells you how much charge your battery has.A fully charged battery is indicated when thelight is green. As the battery discharges, thelight will turn orange. When the light is red,the battery is almost empty. When thebattery is dead, the tool will automaticallyturn off. This wil l be a sudden stop asopposed to a gradual winding down of thetool. Simply recharge the tool and reuse.

Green Light - 100% charge remaining.

Orange Light 50% charge remaining orthe tool is being used in heavy applications(low battery voltage due to current draw).

Red Light - 25% charge remaining.

Red Flashing Light - tool is about to shut offor battery is too hot or too cold for use. Turntool off and let battery return to normaloperating temperature before resuming use.

IMPORTANT CHARGING NOTES1. The charging base was designed to charge

the tool only when the battery temperature isbetween 32F (0C) and 113F (45C). If thetool is too hot or too cold, the charging basewill not charge the tool. (This may happen ifthe tool is hot from heavy use). When thetool temperature returns to between 32F(0C) and 113F (45C), the charging basewill automatically begin charging.

2. A substantial drop in operating time percharge may mean that the battery is nearingthe end of its life and should be replaced.

3. Remember to unplug the power adapterduring storage period.

4. If tool does not charge properly:

a. Check for voltage at outlet by plugging insome other electrical device.

b. Check to see if outlet is connected to alight switch which turns power off whenlights are turned off.

c. Check charging base and power supplyterminals for dirt. Clean with cotton swaband alcohol if necessary.

d. If you still do not get proper charging, takeor send tool to your local Dremel ServiceCenter.

Note: Use of power supply not sold by Dremelwill void the warranty.
