Warning

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

limitations and hazards in using the jointer. Decals are placed on each machine as reminders of good safety practice.

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

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

6. Use extra care in the location of the jointer in the shop. Place the machine so that potential kickback

area is not in line with aisles, doorway, wash stations, or other work areas.

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

have impact resistant lenses; they are not safety glasses.

8. 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.

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

10. 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.

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

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

13. Make certain the machine is properly grounded.

14. 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.

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

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.

16. 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 upon completion of maintenance.

17. Make sure the jointer is firmly secured to the floor or bench before use.

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

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

20. 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.

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

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

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

careless acts that can result in serious injury.

24. Maintain a balanced stance at all times so that you do not fall or lean against the kniv es or other

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

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

26. Maintain tools with care. Keep knives sharp and clean for the best and safest performance. Follow

instructions for lubricating and changing accessories.

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. See Figure 1.

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 work piece has knots, holes, or

foreign materials such as nails. It can also occur when the stock is fed against the grain on the jointer. The grain must run in the same direction you are cutting. Before attempting to joint or plane, each work piece 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.

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

even death.

Crate #2 contents

1 table and fence assembly 1 drive belt 1 belt guard 1 cutterhead guard 2 push pads 1 hardware bag 1 knife setting gauge 1 manual 1 warranty card

The contents of the hardware bag are shown in Figure 4.

NOTE: Exposed metal surfaces such as the table and fence have been given a protective coating at the factory. This 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.

Figure 4

Installation and Assembly

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

Tools required for assembly:

9/16" wrench 12mm wrench screwdriver (phillips or flat head)

Locate the jointer on a level floor. If using a mobile base, be sure to lock the wheels before assembling, operating or adjusting the jointer.

1. With help from an assistant, lift the jointer

base assembly onto the stand, matching the 3-hole pattern in the table base to that in the stand.

2. Secure jointer base to stand with three 3/8 x

2-3/8 bolts, six 3/8 flat washers, three 3/8 lock washers and three 3/8 hex nuts (Figure

5). Tighten with 9/16" wrench.

Figure 5

3. The stand can be secured to the floor using

two anchor bolts (not provided) through the holes inside the bottom of the stand.

Aligning Pulleys

Place a straight edge against the motor pulley and cutterhead pulley to make sure they are aligned. If adjustment is necessary, loosen the set screws in the motor pulley, and slide it as needed until alignment is achieved. Re-tighten set screws.

Mounting Drive Belt

1. Place the belt into the groove of the

cutterhead pulley.

2. Reach through the dust chute opening in the

side of the stand with a 12mm wrench, and loosen the nuts on the motor mount screws (Figure 6).

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

place the lower end of the driv e belt into the motor pulley groove.

4. Let the motor slide down and push down on

it until the belt is properly tensioned. NOTE: There should be only moderate deflection in the belt midway between the pulleys when using light finger pressure (Figure 7).

5. Tighten the four hex nuts on the motor

mount screws.

Mounting Pulley Guard

Place the pulley guard (A, Figure 8) as shown, and secure with knob (B, Figure 8).

Figure 6

Figure 7

Mounting Dust Chute

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.

Place the dust chute over the opening in the jointer stand, and secure with four 1/4-20 x 1/2 pan head screws and four 1/4 flat washers (Figure 9)

Connect a dust collection hose to the dust chute on the jointer and secure it with a hose clamp or duct tape. NOTE: Dryer vent hose is not acceptable for this purpose.

Figure 8

Figure 9

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 “hard-wire” the jointer directly to a service panel. The circuit for the machine should be a dedicated circuit.

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 motor wiring 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.

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 are the same on the motor nameplate and 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)

Consult the wiring diagram inside the starter box cover. A diagram is also included on pages 3738 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 relay (see Figure 10) as close as possible to the amperage of the Jointer motor at 460V, as listed on the motor plate.

2. Move the fuse (Figure 10) from the 230V

slot to the 460V slot.

3. Re-connect the incoming leads to the motor

for 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.

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!).

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.

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 11 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.

Tools required for adjustments:

8mm & 12mm wrenches 4mm hex wrench machinist's protractor or adjustable square steel straight edge

Cutter Guard

Removing Guard:

Some adjusting procedures, as well as rabbeting operations, will require removal of the guard. Simply loosen handle on rabbeting ledge (Figure 12) and vertically lift guard out of the hole.

Mounting Guard:

The guard is spring tensioned. When mounted, it must have enough tension to completely cover the cutterhead, and press firmly against the fence. To adjust the guard tension:

Figure 12

1. Disconnect machine from power source.

2. Release the fence locking handle (A, Figure

13) and remove the two hex nuts and washer (B, Figure 13) which hold the fence to the fence support. Lift up the fence assembly and set it out of the way of the cutter guard.

3. Rotate the cutter guard (A, Figure 13) to the

right and set it into its hole as shown. Firmly tighten the handle (B, Figure 13). The farther to the right you set the guard, the stronger tension it will have.

4. Rotate the guard counterclockwise (C,

Figure 14) until it covers the cutterhead. NOTE: Keep hands away from knives! Hold it in this position (using an assistant or block of wood) and re-mount the fence.

5. 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 handle (Figure

12) is tight. If guard still drags, the guard assembly may need to be replaced.
