Warning

1. Read and understand the entire owner’s manual before attempting assembly or operation.

2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with

all of these warnings may cause serious injury.

3. Replace the warning labels if they become obscured or removed.

4. This jointer is designed and intended for use by properly trained and experienced personnel only. If

you are not familiar with the proper and safe operation of a jointer, do not use until proper training and knowledge have been obtained.

5. Do not use this jointer for other than its intended use. If used for other purposes, WMH Tool Group,

Inc. disclaims any real or implied warranty and holds itself harmless from any injury that may result from that use.

6. Always wear approved safety glasses/face shields while using this jointer. Everyday eyeglasses only

have impact resistant lenses; they are not safety glasses.

7. Before operating this jointer, remove tie, rings, watches and other jewelry, and roll sleeves up past

the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips are recommended. Do not wear gloves.

8. Wear ear protectors (plugs or muffs) during extended periods of operation.

9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities

contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead based paint.

• Crystalline silica from bricks, cement and other masonry products.

• Arsenic and chromium from chemically treated lumber.

Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area and work with approved safety equipment, such as face or dust masks that are specifically designed to filter out microscopic particles.

10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.

11. Make certain the switch is in the OFF position before connecting the machine to the power supply.

12. Make certain the machine is properly grounded.

13. Make all machine adjustments or maintenance with the machine unplugged from the power source. A

machine under repair should be RED TAGGED to show that it should not be used until maintenance is complete.

14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting

wrenches are removed from the machine before turning it on.

15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance

purposes, use extreme caution and replace the guards immediately after maintenance is complete.

16. Check damaged parts. Before further use of the machine, a guard or other part that is damaged

should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.

17. Provide for adequate space surrounding work area and non-glare, overhead lighting.

18. Keep the floor around the machine clean and free of scrap material, oil and grease.

19. Keep visitors a safe distance from the work area. Keep children away.

20. Make your workshop child proof with padlocks, master switches or by removing starter keys.

21. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are

careless acts that can result in serious injury.

22. Maintain a balanced stance at all times so that you do not fall or lean against the cutterhead or other

moving parts. Do not overreach or use excessive force to perform any machine operation.

23. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for

which it was not designed. The right tool will do the job better and more safely.

24. Use recommended accessories; improper accessories may be hazardous.

25. Maintain tools with care. Keep knives and knife inserts sharp and clean for the best and safest

performance. Follow instructions for lubricating and changing accessories.

26. Remove loose items and unnecessary work pieces from the area before starting the machine.

27. Turn off the machine and disconnect from power before cleaning. Use a brush or compressed air to

remove chips or debris — do not use your hands.

28. Do not stand on the machine. Serious injury could occur if the machine tips over.

29. Never leave the machine running unattended. Turn the power off and do not leave the machine until it

comes to a complete stop.

30. When working a piece of wood on the jointer, follow the 3-inch radius rule: The hands must never be

closer than 3 inches to the cutterhead.

31. Always use a hold-down or push block when surfacing stock less than 12 inches long, or 3 inches

wide, or 3 inches thick.

32. Do not perform jointing operations on material shorter than 8 inches in length, narrower than 3/4

inches, or less than 1/4 inch thick.

33. Do not make cuts deeper than 1/8 inch to avoid overloading the machine and to minimize chance of

kickback.

34. Never apply pressure to stock directly over the cutterhead. This may result in the stock tipping into

the cutterhead along with the operator’s fingers. Position hands away from extreme ends of stock, and push through with a smooth, even motion. Never back workpiece toward the infeed table.

35. “Pull-out” and the danger of kicked back stock can occur when the workpiece has knots, holes or

foreign materials such as nails. It can also occur when the stock is fed against the grain. The grain should run in the same direction you are cutting. Before attempting to joint or plane, each workpiece must be carefully examined for stock condition and grain orientation.

NOTE: At certain times it may be necessary to plane against the grain when working with a swirl grain wood or burl. With this type of work the operator must use a lesser depth of cut and a slow rate of feed.

Familiarize yourself with the following safety notices used in this manual:

This means that if precautions are not heeded, it may result in minor injury and/or

possible machine damage.

fatal injury.

This means that if precautions are not heeded, it may result in serious or possibly even

Assembly

Exposed metal surfaces, such as the table and fence, have been given a protective coating at the factory. This coating should be removed with a soft cloth and solvent (such as mineral spirits) once the machine has been assembled. Do not use an abrasive pad as it may scratch the exposed surfaces.

NOTE: If any procedure described herein needs further clarification, consult the assembly drawings at the back of this manual.

Tools required for assembly:

3mm and 6mm hex (Allen) wrenches 17mm, 14mm, (two)12mm open-end wrenches screwdriver

Assembling Jointer to Stand

Refer to Figure 6.

1. Locate the stand on a level floor. If desired,

the stand can be secured to the floor using

two anchor bolts (not provided) through the

holes inside the bottom of the stand. If using

an optional mobile base, be sure to lock the

wheels before assembling, operating or

adjusting the jointer.

The jointer is very heavy.

Exercise proper caution when lifting it.

2. Use a hoist or forklift with straps, to lift the

jointer onto the stand. (The front of the

jointer should face the same direction as

curved front of the stand.)

3. Shift the jointer atop the stand until the 3-

hole pattern aligns in jointer base and stand.

4. Secure jointer base to stand with three 3/8”-

16 x 2-3/8” carriage bolts (AA), six 3/8” flat

washers (BB), three 3/8” lock washers (CC)

and three 3/8” hex nuts (DD). (Note: On the

left hand hole, it may be easier to insert the

carriage bolt from beneath as shown.) Only

finger tighten bolts until all three are

properly inserted; then fully tighten the hex

nuts with a 14mm wrench and a 17mm

wrench on the heads of the screws.

Cutterhead Guard

Place the post of the cutterhead guard (J, Figure

6) into the hole on the rabbeting ledge as shown. (Always use caution when working near the cutterhead knives!) Rotate the locking handle until it tightens into the groove on the cutterhead guard post.

Figure 6

The guard is spring tensioned. When mounted, it must have enough tension to completely cover the cutterhead, and press firmly against the fence. Test the tension by swinging the guard away from the fence and then releasing it. The guard should snap back to the fence.

NOTE: The guard must operate freely and must not drag on the rabbeting ledge or infeed table. If dragging occurs, check that the locking handle (Figure 6) is tight. If guard still drags, the guard assembly may need adjustment or replacement.

Removing Guard:

Some adjustment procedures, and rabbeting operations, will require removal of the guard. Loosen handle on rabbet ledge and vertically lift guard out of the hole.

Aligning Pulleys

Check that the motor pulley and cutterhead pulley are aligned; this will keep the belt vertical and help prevent excess wear on it. If adjustment is necessary, loosen the set screws in the motor pulley using a hex wrench, and slide the pulley as needed until alignment is achieved. Re-tighten set screws.

Installing Drive Belt

Refer to Figure 7.

1. Remove the belt guard (shown in Figure 9).

2. Place one end of the belt through the

opening in the stand and into the groove of

the cutterhead pulley.

3. Reach through the dust chute opening in the

side of the stand with a 12mm wrench, and

keep the motor mount screw heads

stationary, while loosening the hex nuts with

a second 12mm wrench from inside the

stand (Figure 7).

4. Lift up on the motor to provide slack, and

place the lower end of the drive belt into the

motor pulley groove.

5. Let the motor slide back down and push

down on it until the belt is properly

tensioned. NOTE: There should be only

moderate deflection, usually about ½”, in the

belt midway between the pulleys when

using light finger pressure (Figure 8).

6. Tighten the four hex nuts on the motor

mount screws (Figure 7).

Figure 7

Figure 8

Installing Belt Guard and Door

Refer to Figure 9.

Mount the belt guard ov er the shaft as shown, and install the knob to secure it in place.

Set the lip of the door over the bottom edge of the stand opening. Rotate the door knob to hold the door to the stand.

NOTE: When the jointer is being operated, the two M6 pan head screws (KK) and M6 flat washers (LL) should be installed to fully secure the door. At this moment, however, leave these screws off until the switch has been installed.

Installing Switch Arm

Refer to Figure 10.

1. Align the holes of the switch arm with the

holes on the jointer stand, while slipping the

electrical cord down through the larger hole

in the stand.

2. Secure the switch arm with four 5/16”-18 x

3/4” socket head cap screws (EE), four

5/16” lock washers (GG), and four 5/16” flat

washers (FF), using a 6mm hex wrench.

3. Open the stand door, and join the

connectors of the switch cord and motor

cord, as shown in the detail in Figure 10.

Installing Dust Chute

Refer to Figure 11.

It is strongly recommended that a dust collection system (not provided) be connected to the jointer. It will help keep your shop clean, and reduce the risk of health problems due to wood dust. The dust collector should have sufficient capacity for this size jointer. Visit our website at www.powermatic.com to see a range of available dust collection units.

Figure 9

Figure 10

Place the dust chute over the opening in the jointer stand, and secure with four 1/4”-20 x 1/2” pan head screws (HH) and four 1/4” flat washers (JJ).

Connect a suitable dust collection hose to the dust chute on the jointer and secure it with a hose clamp. NOTE: Dryer vent hose is not

acceptable for this purpose.

Figure 11

(hose and clamp not provided)

Installing Fence Handwheel

Refer to Figure 12.

Install the handwheel (H) onto the shaft, and tighten the set screw with a 3mm hex wrench.

Knife Gauge Assembly

Refer to Figure 13.

The knife gauge assembly consists of a bar, two end pieces and two e-clips. Slide the end pieces onto the ends of the bar as shown, and use a pliers to push the e-clips into the grooves on the bar.

(model 60C only)

Storing the Push Blocks

The two provided push blocks have a magnetic base – you can attach them to the jointer stand or any metallic surface, to keep them within easy reach.

Electrical Connections

Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

The Jointer is equipped with either a single phase, 230 volt motor; or a three phase, 230/460 volt motor.

The single phase unit is factory wired for 230 volts. You may either install a UL/CSA listed plug suitable for 230 volt operation, or “hardwire” the jointer directly to a service panel. It is recommended that the single phase jointer be connected to a dedicated, minimum 20 amp circuit with a 20 amp circuit breaker or time delay fuse. Local codes take precedence over recommendations.

The three phase motor is pre-wired for 230 volt. It may be re-connected for 460 volts by changing the connections as illustrated in the diagram in the starter box (see “Converting from 230 Volt to 460 Volt”). You may either install a UL/CSA listed plug suitable for the specific voltage, or “hard-wire” the jointer directly to a service panel. It is recommended that the three phase jointer, when operated at 230 volts, be connected to a dedicated, minimum 20 amp circuit with a 20 amp circuit breaker or time delay fuse. When operated at 460 volts, connect the jointer to a dedicated, minimum 15 amp circuit with a 15 amp circuit breaker or time delay fuse. Local codes take precedence over recommendations.

Figure 12

Figure 13

(model 60C only)

If the jointer is to be hard-wired to a panel, make sure a disconnect is available for the operator. During hard-wiring of the machine, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the jointer will be connected. Place a warning placard on the fuse holder or circuit breaker to prevent it being turned on while the machine is being wired.

Grounding Instructions

This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.

Improper connection of the equipmentgrounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes, is the equipmentgrounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Repair or replace a damaged or worn cord immediately.

IMPORTANT: Make sure the electrical characteristics listed on the motor nameplate match those of the power source, and make sure the circuit on which the jointer will be used is properly fused and that the wire size is correct.

Converting from 230 Volt to 460 Volt (Three Phase Only)

Refer to Figure 14.

Consult the wiring diagram inside the starter box cover. A similar diagram is also included at the back of this manual. The Jointer must comply with all local and national codes after being wired.

1. Remove the starter box cover and adjust the

dial on the overload relay as close as

possible to the amperage of the motor at

460V, as listed on the jointer’s motor plate.

2. Move the fuse from the 230V slot to the

460V slot.

3. Re-connect the incoming leads to the motor

in accordance with 460 volt operation, as

shown in the wiring diagram.

4. If using a plug, install a proper UL/CSA

listed plug suitable for 460 volt operation.

Figure 14

(230V to 460V conversion)

Three-Phase Test Run

On the three-phase unit, after wiring has been completed, you should check that the incoming leads have been connected properly:

1. Connect machine to power source and

press the start button. Make sure cutterhead

is clear of all obstructions! (See page 21 for

more detailed instructions on the switch.)

2. The cutterhead should rotate clockwise as

viewed from the front of the machine. If the

cutterhead rotation is incorrect, press the

stop button and disconnect machine from

power.

3. Switch any two of the three leads to the

motor, then re-connect to power.

Extension Cords

Make sure your extension cord is in good condition. Always use a cord that is heavy enough to carry the current your product will draw; the cord rating must be suitable for the 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.

Use the chart in Figure 15 as a general guide in choosing the correct size cord. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
