Warning

As with all machi nes, there is a cert ain amount of hazard involved wit h the use of t his planer . Use t he machine with t he r es pect and caution demanded where safety pr ec autions are concerned. When normal safety pr ecautions are overlooked or ignored, per s onal injury to t he operator c an result.

Read, underst and and f ol low the safety and operating instructions found in this manual. Know the limitations a nd hazards associated with this machine.

Electrical grounding. Make certain that the machine frame is electrical ly gr ounded and t hat a ground lead is included in the incoming electrical service. I n cases where a cor d and plug are used, make certain that the grounding plug connects t o a suitable ground. Follow the grounding procedure indicated in the National Electrical Code. I f connected t o a circ uit protected by fuses, use time delay fuse marked “D”.

Eye safety. W ear an approved safety shield, goggles, or glasses to protect eyes. (NOTE: Commo n eyeglasses are only impact- r es istant, t hey are not safet y glasses. )

Personal protect i on. Bef or e oper at ing the machine, remove tie, r ings, wat c h and other jewelry and roll up sleeves above the elbows. Remove all loose outer clot hi ng and co nfine long hair. Protective type footwear should be used. Where the noise exceeds t he level of exposure allowed i n Section 1910.95 of the OSHA Regulations, use hearing protective devices. Do not wear gloves.

Guards. Keep the machine guards in place for every operat ion for w hich they can be used. If any guards are removed for maintenance, DO NOT OPER ATE the mac hi ne until the guards are reinsta lled.

Placement. Place machine so that pot ential kickback ar ea is not in line with aisles, doorways, wash stations, or ot her wor k areas. Do not expose machine to rain or use in damp locations.

Work area. Keep the floor around the mac hi ne clean and free of scrap material, saw dust, oil and other liquids to minimize the danger of tripping or slipping. Be sure the table is free of all scrap, f or eign material and tools before star t ing to cut. Make certain the work area is well lighted and that a proper exhaust system is used to minimize dust. It is recommended that anti-skid floor strips are used on the floor ar ea where the operator normally stands a nd t hat each machine’s w or k ar ea be marked off. Provide adequate work s pace around the machine.

Avoid acc idental star ting: Make c ertai n motor sw itch is in off positio n before co nnecti ng power to t he machine.

Operat or position. M aintain a balanced sta nce and keep yo ur body under control at all times. Stand to one side out of line with the table and make sure no one else is standi ng in line with the table.

Housekeeping. Before turning on machine, remove all extra equipme nt such as keys, w r enches, scrap, and cleaning rags away f r om the machine

Careless acts. Give the wor k you are doing your undivided attentio n. Looki ng aro und, carr ying on a conversation, a nd “horseplay” ar e car eless act s that can result in serious injury.

Disconnect machin e bef or e per f or ming any service or maintenance or w hen changing blades. A machine under repair should be RED TAGGED to show it should not be used until the mainte nance is complete.

Maintain tools in top condition. Keep tools sharp and clean for saf e and best per f ormance. Dull tools increase noise levels and can cause kickbacks and gla zed s urfaces. Check the condition and adjustment of the tools befor e making any cuts. Follow t he sharpening instructi ons on knife gr indi ng and jointi ng, installi ng and adjustments.

Hand safety. Keep hands outside the mac hine. NEVER reach under t he guards to t r y to clear stock that stops f eeding. Do not clear chips and sawdust with hands; use a brush. Do not have any part of t he hands under that part of the board that is over the table when starting a cut; the infeed roll will engage the board and force it dow n against the table causing a pinching action. Do not operat e machine while the gear cover is open.

Cutterhead rotation: Be sure cutterhead rotates under power in a co unterclockwise direction w hen viewed fr om the main drive motor side.

Mater ial conditi on: Do not p lane boards wit h loose knots or w ith nails or a ny foreign mater ial o n its surface. Knife impact o n these objects can cause the knives to be pulled out a nd cause them to shatter against the chipbreaker or pres sure bar. Twist ed, warped, or in wind stock should first be joi nted on one surface before attempting to plane a parallel surface on the planer. Serious stock flaws cannot be removed by use of a planer alone.

Machine adjustme nt s: M ake all machine adjustments with power off except feed rate. Avoid kickback: To avoid kickbacks, use this machine for single board surfacing only. Never make cuts

deeper than 1/8 inch (3mm). Job completion. If the operator leaves the machine area for any reason, the planer should be turned

"off" and the cutterhead sho uld come to a complete st op bef or e his departure. I n addition, if the operation is complete, he should clean the planer a nd the work area. Never clean the planer with power "on" and never use the hands to clear sawdust and debris; use a brush.

Replacement par t s. Use only Powermatic or fact or y authorized replace me nt part s and accessories; otherwise the warr anty and guarantee is null and void.

Misuse. Do not use this Powermatic planer for ot her than its intended use. If used for other purposes, Walter M eier (Manufacturi ng), I nc., disclai ms any real or implied w ar r anty and holds itself harmless f or any injury or damage which may result f r om that use.

Installation and Assembly

Tools required f or asse mbly:

Forklift or hoist with slings 10-12,12- 14mm open-e nd wrenches (provided) 4 and 5mm hex wrenches (provided) 16mm open-e nd wrench

Remove the screws holding the planer to the pallet and use a forklift or hoist to lift the planer off t he pallet. Forks and straps should alw ays be placed under t he four lifti ng handles when lifti ng this machine (Fig ure 5). The lift ing handles can be pushed back in when not in use.

The pla ner should b e operated i n a well- lit area with good ventilation. It can be rolled on its casters to the desired location. Press the foot pedal (Figure 6) to prevent movement during operation or adjustments.

Exposed surfaces, such as tables, rollers, cutterhead, etc., have been given a protective coating at the factory. This should be removed with a soft cloth moistened with a good commercial solvent. Do not use acetone, gasoline, lacq uer thi nner, or other solvents with a low flas h poi nt. Do not use an abras ive pad because it may scratch the polished cast iron surfaces.

Figure 5

Figure 6

Use care when cleaning

around the cutterhead area – knives are extremely sharp!

Handwheel

1. Place the key into the slot on the shaft

(Figure 7), and mo unt the handw heel to t he shaft, making sure it is oriented so it slips over the key.

2. Peel off the backing of the directio nal label,

and attach it to t he center of the handwheel. Place flat washer a nd hex nut o n s haft and tighten with 16mm wrench.

3. Mount the handle i n t he t hreaded hole in the

handwheel, and tighte n with a 12mm wrenc h placed over the flat on the handle.

Starter Box

Mount the controls as shown in Figure 8, with the two socket head cap screw s w hich yo u’ll find mounted to the head casting. Use a 5mm hex wrench.

Figure 7

Figure 8

Extension Tables

1. Mount a cast iron table to the edge of the

main table with three M8 x 25 hex cap screw s ( Figure 9) using a 12mm wrench. Do not fully tighten yet.

2. The extensio n table must be le veled w ith t he

main table. P lace a straig ht edge (suc h as a jointed board) across the extension table and the main table.

NOTE: T he straig ht edge should not lie over the raised t able rollers, as t his wo uld distort the leveling process. Either place the straight edge just short of t he table rollers, or lower the table rollers completely into the table (see page 11) while mounting the extension tables.

3. Insert three socket set screws with a 4mm

hex wrench, and screw them in or out as needed until tables are level.

4. Securely tig hten the hex cap screw s .

5. Mount the second extension table to the

opposite side of the pla ner table, usi ng t he same procedure.

Figure 9

Dust Hood

Mount the dust hood to the rear of the head casting with three M6 x 12 socket head cap screws with lock washers, and three M5 x 10 hex cap screws with flat washers. See Figure

10. It is recommended that you use a dust collection

system with this planer. If you are not using a dust collection system, do not attach the dust hood to the planer, as t he accumulation of dust inside the hood may create a safet y hazard, or eventually cause jammi ng of the rollers.

Elect ri cal Connectio ns

Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. The machine must be prop erly grounded t o help prevent electrical shock and possible fatal injury.

A power plug is not provided with the 15S or 15HH planers. You may either connect a 230 volt plug or "hard-wire" the machine directly to your electrical panel provided there is a disconnect near the machine. Consult electrical schematic on page 38 f or further clarification of wiring setup.

Figure 10

It is r ecommended that the 15S or 15 HH Planer be connected t o a dedicated, minimum 40 amp circuit with a 40 amp circuit breaker or time delay f use. Loc al codes take precedence over

recommendations.

This machine must be grounded. Grounding provides a path of least res istance to help d ivert current away from the operator in case of electrical malfunct ion.

Make sure the voltage of your power supply matches the specificat ions on the motor plate of the machine.

Extension Cords

The use of an extension cord is not recommended for this machine, but if one is necessary make sure the cord rating is suitable for t he amperage listed on the machine's motor plate. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating.

The chart in Figure 11 shows the correct size cord to use based on cord length and motor plate amp rating. If in doubt, use the next heavier gauge. The smaller the gauge number the heavier the cord.

Disconnect machine from

power source before making any adjustments ( except f eed r at e) .

Belt Tension

Inspect the tension of the belts fr equently duri ng the first few times you use the planer. Belts often stretch during this trial period. If they require tightening, pr oceed as follows:

1. Remove the belt guard and the rear panel.

2. Loosen the bottom nut on the motor adjustment screw (Figure 12) with a 17mm wrench.

3. Tur n the top nut on t he adjust ment scr ew t o lower the motor plate, which will increase the belt tension.

4. Proper tension is achieved when there is slight deflectio n in the belt midway between the pulleys, using moderate f inger pr ess ure.

5. Tighten the bottom nut on the adjustment screw (Figu re 12).

Figure 12

Pulley Alignment

The pulleys should be in line for proper belt operation.

1. Remove the belt g uard a nd place a s traig ht edge against the faces of both pulleys (Figure 13).

2. If the straight edge does not lie flat on both pulley faces, open the rear panel and loose n the four hex nuts on the motor plate (see Figure 12) w ith a 12mm wrench.

3. Nudge t he motor left or r ight until the pulleys are in alignment.

4. Tighte n hex nuts and replace covers.

Tab le Roll ers

Your planer is supplied with two table rollers (Figure 14) which turn as the stock is fed into the machine, thus reducing friction. It is not possible to give exact dimensions on the proper height setting of t he table rollers beca use eac h type of wood behaves differently. As a general rule, however, when planing rough stock the table rollers should be set at high position. When planing smoot h stock the rollers should b e set at low po s ition.

Figure 13

NOTE: When raisi ng the roller higher abo ve the table, t he range is from zero to 0.06" (Figure 15).

Figure 15

The table rollers are factory set for average planing and are parallel to the table surface. If you desire to adjust the table rollers higher or lower, pr oceed as follows:

1. Disconnect machi ne from pow er source.

2. Lay a str aight edge across bot h rollers.

3. On one side of the table, loosen the set screw s (Figure 16) with a 3mm hex wrench, and turn the eccentric shafts to raise or lower the rollers.

4. When pr oper height is ac hie ved, tighte n set screws.

Figure 14

Figure 16

5. Adjust the rollers from the opposite side of the table in the same manner.

IMPORTANT: Be sure that the height of front and rear rollers are the same. And the table rollers must always be set parallel to the table.

Cutterhead

Although your planer was carefully adjusted at the factory, it should be checked before being put into operation. Any inaccuracies due to rough handling in transit can be corrected by following the directions in t his manual.

To check the adjustments yo u will need feeler gauges, and a di al gauge or home-made ga uge block made of hardwood. This ga uge block can be made by fo llowing the di me nsio ns s hown in Figure 17.

Repl aci ng Knives (Model 15S only)

Figure 17

Use caution and proceed

slowly when working with and around the knives – they are extremely sharp!

When dull knives are replaced, care must be exercised in setting the new knives into the cutterhead. There is a certain procedure to follow which will ensure a proper setting of knives on the 15S Planer. Proceed as f ollows:

1. Disconnect machi ne from pow er source.

2. Remove the dust hood and the top cover. Remove the chip deflector (Figure 28 s how s the chip deflector). Remove the belt g uard so you can rotate the cutterhead using t he pulley.

3. Remove the gib screws with the T-handle hex wrench, as shown in Figure 18, and remove each gib one at a time.

4. Carefully remove the knife, and clean the cutterhead slot of any dust or debris.

5. Place the new knife into the cutterhead slot.

6. IMPORTANT: As you proceed with knife installation, make sure the wings on both ends of each hole (see Figure 18) are completely inserted into the groove in the cutterhead. Failure to do this may result in knife breakage during operatio n.

Figure 18 – Model 15S onl y

7. There are a total of three short gibs and twelve long gibs on the cutter head. It is not important w het her long or short gib is used in any particular location along the knife. Of course, eac h knife must use one short gib.

8. Put the first gib in place at the end of the cutterhead. Use the knife adjustment pins shown in Figure 19. The adjust ment pins fit down through the smaller holes in the gib, knife, and cutterhead, helpi ng to align t hem.
