,PI.ANER SAFETY INSTRUCTIONS
1. Read, understand, and lollow the safety and operating instructions found in this manual. Know thelimitations and hazards associated with this planer. A safety rules decal is installed on each machine
. to serve as a reminder of basic safety practice.2. Grounding of the planer: Make certain that the machine frame is electr ical ly grounded and that a
grounding lead is included in the incoming electr ical service. ln cases where a coid and plug are used,make certain that the grounding lug connects to a sui table ground. Fol low the groundingirocedureindicated by the National Electric Oode.
3. Eye safety: Wear an approved safety shield, goggles, or glasses to protect eyes when operating theplaner.
4. Personal protection: Before operating the machine, remove, tie, rings, watch and other jewelry and rollup sleeves above the elbows. Remove all loose clothing and confinJlong hair. Protective typeiootwearshould be worn and hearing protectors should be used where noise exceeds the level of e*poJu re allowedin sect ion 1910.95 of the osHA regulat ions. Do not wear gloves.
5. Work area: Keep the f loor around the machine clean and free of scrap mater ial , sawdust, oi l or greaseto minimize the danger of t r ipping or sl ipping. Be sure the table is l ree of al l scrap, foreign mater ialand tools before start ing a cut. Powermatic recommends the use of ant i -skid f loor str ips Jn the f loorarea where the operator normal ly stands and that each machine's work area be marked off . Make cer-tain the work area is wel l l ighted and that a proper exhaust system is used to minimize dust. providefor adequate work space around the machine.
6. Guards: Keep the machine guards in place at al l t imes when the machine is in use. l f removed formaintenance purposes, use extreme caut ion and replace the guards on complet ion of the mainte-nance task before using the planer. Do not operate the machine with the guards off.
7. Do not over reach: Maintain a balanced stance and keep your body undeicontrol at all times. Do notover reach.
8. Maintain tools in top condition: Keep tools sharp and clean for safe and best performance. Dull toolsincrease noise levels and can cause kickbacks and glazed surfaces. Broken tools or tools that are notsecurely locked in the cutterhead can be thrown out of the planer'causing severe or fatal injury as wellas severe damage to the machine. Check the condit ion and adjustment of the tools before making anycuts. Fol low the sharpening instruct ions on kni fe gr inding and joint ing, instal l ing and adjust inenis.Caution: Do not use knives that have been reground to lesi than bra" 1t6 mm) heig-ht on standard cut-terheads or 1/2" (13 mm) height on quiet cutterheads.
9. Operator posi t ion: Stand to the lef t s ide out of l ine with the table and make sure no one else is stand-ing in l ine with the tabte.
10. Hand safety:Keep hands outside the machine. Never reach under the guards to try to clear stock that' stops feeding. Do not clear chips and sawdust with hands; use a brush. Note caution decal at rear ofthe machine' Do not have any part of the hands qnder that part of the board that is over the table whenstarting a cut; the infeed roll will engage the board and force it down against the table causing apinching act ion.
- !
11. Cutterhead rotation: Be sure cutterhead rotates under power in a counterclockwise direction whenviewed from the main dr ive motor side.
12. Machine adiustments: Make all machine adjustments with power off except feed rate.13. Machine capacity: Do 49t make any cuts requir ing more power than isavai labte on the machine. Eachmachine has a caut ion decal on the front panel indicat ing the maxirnum depth of cut and the maxi-
mum dif ference in board thickness al lowed when mult iple board surfacing when i t is equipped to dothat operation. Do not attempt to feed two boards side by side (multiple board surfacing) on any ma-chine not equipped with a sect ional ized infeed rol l and chipbreaker.
14. Material condition: Do not plane boards with loose knots- or: with nails or any foreign materiai on itssurface. Knife impact on these objects can cause the knives to be pulled out and cause them to shatteragainst the chipbreaker or pressure bar. Twisted, warped, or in wind stock should f i rst be jointed onone surface before attempting to ptane a paratlet surface on the planer. Serious stock flaws cannot beremoved by use of a planer alone.
15. Stacked boards: Do not feed stacked boards through a ptaner;'a kickback can occur causing severeor fatal injury.
16. Short stock: Do not attempt to plane boards shorter than '12" (305 mm) in length without butt ing aboard of equal thickness behind i t to help i t through the planer. Be sure the tast board of a buttect se-quence rs 12" (305 mm) long or longer.
17. Stock stops feeding: l f the board being planed stops feeding, disengage or turn the feed bff and turn' the power off . Wait unt i l the cutterhead comes to a complete stop before lowering the table to removethe board. Never lower the table with the power on and the stock st i l l in the machine. A kickback canoccur which could cause a severe or fatal in jury.
t
18. Avold accldental startlng: Make certajn thp motgr switch iS in the off position before connectingpower to the planer.
19. Careless acts: Give the work you are derf.r€ your undivided altention. Looking around, carrying on aconversation, and "horseplay" are carelqqg;€Ots that ean regult in serious injury.
20. Job completion: lf the operator leaves the maehine area for gny reason, the planer shoufd be turned"off" and the cutterhead should come to g Somplete gtop before his departure. ln addition, if the oper-ation is complete, he should clean the plangr and the work Arga, l{ever clean the planer with power"on" and nevet use the hands to clear sa$rdugt and debrio; use a brush.
21. Disconnect machine: Before performing eny oervicg or mainfenance and when changing blades.22. Replacement parts: Use only Powermatig Or faetory authgrized replacement parts and accessories;
othenrise the planer warranty and guarastee will be nutl and void.23. Misuse: Do not use this Powermatic plangf for other than itS intended use. lf used for other purposes,
Powermatic disclaims any real or implie{ Warrenty snd hgfdg itgelf harmless for any injury which mayresult from that use.
Listed below is a table of horsepower and eutterhead r.p.m. for powermatic planers. Do not equipyour planer with motor of higher horseFrpwer nor run the eutterhead in excess of the r.p.m. indi-cated in the table. Doing so voids the waffcnty and Powermatic holds itself harmless lrom any inlurylhat may result.

Recelvlng:Uncrate machine and check for shipping damage. Report any damage to the carrier and your distributor
immediately. lf accessories were ordered with the machine, these wrll be in a separate container andshoufd be checked for completeness and damage. Notify lhe carrier and your distributor immediately ifany items are missing or damaged.
Clean protective coating from all areas and lubricate parts'as indicated in this manual.
tnslallation:Mount machine on a solid foundation, preferably a concrete floor, and lag machine to the floor through
the holes provided in the base (see page 4 for mounting dimensions). The machine area should be clean,dry, well ventilated, and well lighted. Since planers can creale noise problems, the site selection should beone which minimizes reverberant sound from walls, cei l ings and other equipment. Electr icals should be in-stalled so that they are protected lrom damage and exposure. Be sure to properly ground the machineframe.
Exhaust System:When an exhaust system is used, be sure it is of sufficient size to provide an exhaust volume of 1100
cubic feet/min. (31.2 cubic meter/min.). l f an exhaust system is not used, the user is cautioned against thehealth hazard and the limitations in the OSHA regulations for employee or student exposu re to dust particles.
Powermatic recommends that an exhaust system be used with a planer.
lnspection:Before putting power on the machine, check that all screws are tight, that all mechanical functions work
freely and that the cutterhead turns freely without knife contact with the chipbreaker or pressure bar. Peri'odic or regular inspections are required to insure that the machine is in proper adjustment, that al l screws aretight, that belts are in good condit ion, that dust has not accumulated in the electr ical enclosures, and thatthere are no loose or worn electrical connections.
Before Operating:Check the motor and switch wiring diagram tor proper voltage conneclions before applying power to
the machine (see page 17 forwiring diagrams). Turn the main drive motorand feed motor [on 20" (508mm) and24" (6'1Omm) models onlyl on momentari ly to check for proper direction of rotation. Correct as required. cut-terhead should rotate counterclockwise when viewed from the sheave or motor side. The infeed roll shouldturn clockwise when viewed from the motor side of the planer.
Run the machine without cutting for a short period of time to check that all powered functions are oper-ating properly.
Be sure to read and understand the operating instruction manual before using the planer.
Lubrication:The cutterhead, infeed roll and outfeed rotl are mounted on sealed ball bearings and require no lubrica-
tion. The following lubrication chart indicates the lubrication points, frequency, and recommended lubri-cants.

Planer Table:The planer table is raised and lowered by twin ACME screws
supported on thrust bearings and is guided by machine sur_faces on the side panels. The f i t -up to preveni the tabte fromrocking is control led by two gibs in f ront. These gibs shoutd beadjusted individual ly using the gib screws provided (f ig. 1) sothat the ways are l ight ly contact ing on ai l four surfaces. Thegibs should be t ight enough to prevent rocking or movementol the table when the planer is in operat ion.
To do accurate planing, the table must be paral lel with thecutterhead. Lack of paral lel ism results in a taper over thewidth of a board. eheck wi ih siraddie-type knife gage toinsure knives have the same protrusion from the cutterheaoarc [approximatety .1ZS (9.2 mm)] end to end and that eachknife is the same. Maximum deviat ion al lowed for goodp lan ing is .001 ( .025 mm). t f dev ia t ion exceeds.001 ( .025 mm),see sect ion on instal l ing cutterhead knives or sect ion on joint-ing and gr inding knives before level ing the tabie.

Pressure Bar:
Most planing problems can be related to improper sett ing of the pressure bar. l ts funct ions are to hold
the mater ial down after i t passes under the cutterhead and throughout the remainder of the cut. l ts basic
sett ing is to be in l ine with the arc of the cutterhead knives. l f i t is too high, a shal low cl ip wi l loccur 6" (152
mm) in from each end of the board. l f i t is too low, stock wi l l not feed through.
With a bed and feed rol l gage or a gage block and a 1/32" ( .B1mm) thick 6" (152mm) scale as a feelerplaced under the cutterhead, raise the table with i ts elevat ing handwheel to determine the low point of the'arc of a cutterhead knife. Move the gage or gage block and scale under the low point of the extreme r ight
hand side of the table and acl just that end of the pressure bar with the jackscrews provided to be in l ine
with the low point of the kni fe arc ( f ig. 11). Move the gage or gage block and scale to the extreme lef t hand
s ide an6 ad jus t tha t s ide to be in l ine w i th the low po in t o f the kn i fe a rc . Recheck the r igh t s iCe; check the
{ul l width of the pressure bar. l f the center is s l ight ly low, adjust both sides the same amount to br ing thelow point into l ine. Using the bed and feed rol l gage set the ful l length of the pressure bar to be .000 -
.001(.02mm) above the arc of the cutterhead. This ini t ia l setup is a start ing point and f inal adjustment may
have to be made during a test cut.
Tabte Rol ls:Two table rol ls are provided on the planer to help reduce the fr ict ion of the stock on the table as i t feeds
through the machine. Bed rol ls should be adjusted on your 12" planer to be .008 (.2mm) above the table foral l f in ish planing operat ions. To adjust the bed rol ls using the bed and feed rol l gage, zero the rndicator onthe f lat surface of the table and then posit ion the gage over the extreme r ight-hand side of the tabie overthe front bed rol l . Loosen the lock nut and adlust the jackscrew to raise the bed rol l to .008 (.2mm). Movethe gage front to back to f ind the high point of the bed rol l arc. Move the gage to the lef t-hand end of thefront bed roll and repeat the process. Recheck the right-hand end and adjust if necessary. Lock the jack-
Sqrews with the jam nut provided. Repeat the process {or the rear bed roll.

Caut ion: Never stand direct ly behind stock or al low anyone else to do so and do not bend down to see how theslock is feeding. Should a kickback occur, a ser ious or fatal in jury could result .
The infeed rol l should take the mater ial and force i t under the chip breaker and cutterhead. l f the mater ialfeeds through effort lessly, examine the f in ished cut careful ly for imperfect ions. Learning to read a board forimperfect ions wi l l save hours in adjust ing a planer to operate properly. (See Trouble Shoot ing chart on page
for imperfect ions not related to the pressure bar which can develop due to misadjustment and knife wear.)

Turn bo thr ight and lef t hand adjust ing screws the same amount, 1/4lurn clockwise or less, and take another 1/16"(1.S8mm)deep cut. Re-examine the board.

Should the board fai l to feed through, back off s l ight ly on both adjust ing screws unt i l feeding issmooth and the imperfect ions do not reappear. Lock the pressure bar adjust ing screws with the jam nutsprovided. Caut ion: Do not adjust pressure bar with cutterhead running.
Note: Adjustment of the pressure bar wi l l be required whenever knives are resharpened and because ofwear which wi l l occur on the cutt ing edge of the knives, causing feed to be restr icted.
Feed restr ict ion can also occur due to pi tch bui ldup on the table. Be sure the table surface is clean anddust ing the surface with talc occasional ly wi l l a id in smoother feeding and help to prevent pi tch bui ldup.

Knife instal lat ion on a planer can be a di f f icul t and exaet ing process, l f the knives are not to be jointed andground, end-to-end and knife-to-kni fe relatronship must be held within .001 (.03mm) for accurate andsmooth planing. To help avoid cutterhead distort ion in changing gut a s€t of knives, remove and replacethe kn i fe in one s lo t be fore chang ing the nex t kn i fe '
1, Clean al l dust, chips, pi tch and accumulated foreign matter from a cutterhead slot and off of i ts gib.
2. Working with one slot. drop in the kni fe jacks in their seats with the notched surface facing the slot .
3. With the kni fe and gib against each other and the beveled surfaee of the kni fe on the kni fe jack side andthe concave shaped surface of the gib up, insert into the slot . The back edge of the kni fe bevel shouldbe sl ight ly below the outside diameter of the cuttcrhead, Light ly t ighten the two outside and center gibscrews.
4. Take the cutterhead knife gage (Fig. 12) and zero it on the eutterhead outside diameter. As a reminder,different size planers have different cutterhead diameters so that the zero point should be checkedbefore using the gage.
5. Working from the bevel side and close to an outside jeckscrew, sl ide the indicator on the radius of thecut terhead body to establ ish the h igh point o f the kn i fe (F ig. 12) .
6, Using an Allen wrench in the jack, raise the knife to be approximately 1/8'(.125"1(3.1Bmm) projectionfrom the cutterhead body. Move the gage to the opposite end and repeat the process. Finally, check thecenter section to be sure i t is within tolerance. l f i t is low, try backinE off sl ightly on the center gibscrew. l f i t is too high, joint ing and possibly grinding wil l be neeessary. Recheck the ful l length of the.kn i fe and be sure i t is the same height .The heel o f the bevel should be 1/16"( ' l .59mm)or less outs ide oflhe cutterhead body and the top of the gib should be approximately ' l /8" (3.18mm) down from the t ipof lhe knife.
7. Start ing from the center outward, snug down al l gib screws and then repeat process locking them'down.
8. Repeat the preceding method on successive knives making sure that the height from knife to knife islhe same within .001 (.03mm).
9. After al l knives have been instal led, recheck al l gib screws to be sure they are t ight. Loose gib screwscan result in knives being thrown out of the cutterhead causing sev€re damage to the rnachine and
. possible serious or {atal injury to the operator or bystanders., Note: l f alf knives have been removed, a new set musl be irrstal led withotrt loeking the gibs unti l al l knives
and g ibs are in and the g ib screws l ight ly snugged down. The toek ing proeess 'should proceed work ingfrom the center out on each knife and after lockinq al l gib sorsws once, repeat the same sequ'ence unti l al lscrews are equally t ight. Locking one knile in wrthout t lre others in posit ion can cause cutterheaddis tor t ion,
