SPEED SELECTORBy means of levers spindle speeds are selected. Left lever selects a colour. Depending on the color selected, rightlever selects a spindle speed value. For moving these levers, slightly pull them and the rotate.

FEEDS SELECTORTo select the feed speed, turn the side selector until the required point (value).

AUTOMATIC TOOL EJECTOR To remove the tool from the spindle, perform the following operations:

1.—Lower the spindle from the reels a little bit and introduce the extractor bolt .

2.—Raise the spindle from the reels.3.—Hold the too with the hand when raising the spindle or

it will fall on to the table.

ATTENTION: Do not leave the extractor bolt introduced.

RETURN SPRINGTo tauten the return spring in model extract the quill until the

teeth of the working gear can move freely .Then move the reels in the arrow direction and introduce the quill again.

Unfasten the screws in the plastic cover and turn this cover in positive direction, once it is tautened, fasten thescrews again.

TORQUE LIMITERThe gearbox is fitted with a stopping device which works in the event of overload.If the feed stops during drilling and the tool continue to revolve, it is a sign that it is overloaded.When the load is reduced, the feed starts up again.If for any reason, such as due to wear of the limiter discs or the need for a higher working load, it is required to readjust it, we recommend the following action.—From the inspection hole and guided by the limiter assembly shown on page 17 tighten the nut Z5035-03-21.(Index No.79)

This mechanism has been adjusted in our works, by measuring the maximum admissible axial load, with a tens meter. Therefore, do not tighten the nut too much, so as to avoid the risk of breaking the mechanism.

DRILL PROTECTION GUARD

The machine is provided with a security micro

drill guard.

Before pressing the starting pushbutton ,set

the drill guard in the working position,

otherwise the machine controls will not start.

Note If the guard is opened when operating

the machine, the machine will stop.

Do not remove the guard under any circumstances.

ELECTRIC CONNECTION The electric connection is a dangerous operation. This task must be carried out by trained or authorized staff for such purpose. WARNING: The electric cabinet of the machine does not include the protection differential switch. The user must install an individual

power supply for the machine, including a protection differential switch of 0,300 amps sensibility and the earth connection.The present machine has a 4 wire electric hose to connect it to the electric power supply through a protection differential switch. Do always connect the PE protection wire first and after that all the others. Connection voltage: the features sheet shows the voltage the machine must be connected to.Total power installed: 1Kw.WARNING: Once the electric connection has been made, make sure



26

that the main screw turns clockwise and that the motor pump (if required on machine model) pumps the coolant liquid. Should not this happen so, invert the current inlet phases.

ATTENTION: Auxiliary circuit under tension once the main power switch of machine has been deactivated Attention: In this machine, when the main power switch is placed at “0” position, the minimum tension auxiliary circuit remains under tension. For minimum tension auxiliary circuit maintenance o reparation jobs, put first at “0” position the protection differential switch to witch the machine has been connected. In this way, the whole machine electric circuits will remain without electric tension.In some machine models, the operator must open the machine head cover for changing spindle speeds. In that case, press the emergency pushbutton first and then, only the minimum tension auxiliary circuit will remain under tension. The circuit under tension is identified by the orange color wiring or otherwise, corresponding warning tables will be stuck to the associated wiring. The rest of the electric circuit will remain without electric tension. Please, check thoroughly the electric drawing of the supplied machine in the instruction book for any maintenance or reparation job.Note: The machine must be connected to the electric power through a protection differential switch. Any electrical maintenance or reparation job must be made for qualified and trained technician.

SECURITY AND GENERAL INFORMATION.

1. SECURITY.A drilling machine, due to its purpose , is considered an “open machine “,Therefore , some safety measures have to be taken to avoid accidents.

Bear in mind the following safety instructions: The machine must always be operated for the purpose for which was designed. Do not ever stand under a hanging machine or nearby, when it is been loaded for

transportation. Connect the machine to an exclusive electric connection, which includes a differential

switch of protection. Plug in first the green—yellow protection wire and then the others.

The piece must always be fastened with suitable devices. Do not ever handhold the pieces.

Sharpened tools in good condition must always be used. Appropriate tools must always be used, Do not ever adapt a tool for a use for which it

was not designed. Use the correct speeds and feeds for the material being machined as well as for the

tool being used. Use glasses to prevent small chips from getting in the eyes. Insert the tools correctly in the tool holder cone. Fix the piece fastening devices to the machine table. Do not wear baggy clothes, loose gloves, etc, which can be caught by the tool while

reaches the tapping depth previously fixed.

3. CORRECT USE OF THE MACHINE.

The correct use of the machine involves: Not exceeding its working capacity. Operating the machine by qualified and trained staff and according to the points mentioned in the instruction book. Working under the safety systems provided with the machine, checking them and keeping them. Watching the safety measures mentioned in the instruction book and notices on the machine. Wearing clothes which provide personal protection as mentioned in the instruction book. Watching the safety measures which may affect work in the machine and that can be lawfully expected, as well as those demanded in the workshops.

4. PIECE CLAMPING.

Tangential cutting forces and axial forces in the feed direction of the tool are mainly produced during the drilling process. The tangential forces produce a moment of forces which make the piece being drilled turn. Therefore, the pieces to be drilled (or to be machined by one of the operations mentioned above) must be clamped in an appropriate device such as a drillchuck and the drillchuck must be correctly clamped to the machine table. For this reason the machine tables are provided with “T” slots.

The pieces must be clamped conveniently by some clamping device.The clamping devices in turn must be clamped to the machine table.The machine table is provided with “T” slots for such purpose.

5. TOOL FIXING.

The tools generally used in this machine will have parallel or tapershanks. Drillholders are normally used to fix to the main spindle of the machine the parallel shank tools. This fixing device has usually got three jaws, which hold the tool by the parallel part of the shank. These are used for small drill diameters (max. up to dia. 16mm).Bigger diameter drills, usually have taper shank of morse taper type (the ones of smaller diameters to 16mm can also have taper shanks).

The housing in the main spindle to insert the tool is of morse taper type. It is very important to insert the tool taper correctly in the main spindle taper to avoid the tool falling from its housing when turning and provoke an accident. The coupling system itself of the tool male taper in the female taper of the main spindle

is auto-locking, but for it the surfaces of the tool taper and spindle taper must be in contact. To get the best possible contact, the surfaces of the tool taper as well as the spindle taper should be in good conditions. Therefore, it is advisable to handle the tool as well as the main spindle of the machine carefully.

6. CHIPS DURING MACHINING.

The machining process removes material from the piece. This material is released in chips, which can be of different shapes depending on the material itself. The most common ones are of three types: fragmented chips in small bits, short helicoidal chips and long helicoidal chips.The chips fragmented in small bits can be rejected from the machining area and can be dangerous if they reach the eyes of the operator. To avoid this, it is advisable to wear safety glasses.The long helicoidal chips tend to roll up the tool and gain considerable volume before breaking, which is dangerous if they reach the operator as they may produce injuries. The reached volume may also displace the drill protector from its security position,increasing the risk of an accident. It is advisable to use chip breaking tools to machine materials which produce such chips. For further information contact the tool manufacturer.
