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 table saw 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 table saw, do not use until proper training and knowledge have been obtained.

5. Do not use this table saw 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 table saw. Everyday eyeglasses

only have impact resistant lenses; they are not safety glasses.

7. Before operating this table saw, 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. Maintain a balanced stance and keep your body under control at all times. Do not stand in line with

the saw blade or workpiece, and do not allow anyone else to do so.

14. Do not overreach or use excessive force to perform any machine operation. Use a support table or

have a helper or “tailman” take stock away from the back side of the blade.

15. Check the alignment of the splitter, fence and miter slot to the blade. A caution decal is installed on

the guard and splitter assembly to remind the operator of the dangers of misalignment.

16. Maintain tools in top condition. Check the saw blade for cracks or missing teeth. Do not use a cracked

or dull blade or one with missing teeth or improper set. Make sure the blade is securely locked on the arbor.

17. Keep hands clear of the blade area. Do not reach past the blade to clear parts or scrap with the saw

blade running. Never saw free hand. Avoid awkward operations and hand positions where a sudden slip could cause your hand to contact the blade.

18. Always use the splitter, blade guard, push stick and other safety devices for all operations where they

can be used. On operations such as dadoing or molding where the blade guard cannot be used, use feather boards, fixtures, and other safety devices and use extreme caution. Re-install the splitter and blade guard immediately after completing the operation that required their removal.

19. Be sure the saw blade rotates clockwise when viewed from the motor side (left side) of the machine.

20. Do not attempt to saw boards with loose knots or with nails or other foreign material, on its surface.

Do not attempt to saw twisted, warped, bowed or “in wind” stock unless one edge has been jointed for guiding purposes prior to sawing. Do not attempt to saw long or wide boards unsupported where spring or weight could cause the board to shift position.

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

22. 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.

23. 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.

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

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

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

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

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

careless acts that can result in serious injury.

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

30. 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.

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

Never remove the blade insert with the machine running.

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

33. Never leave the tablesaw running unattended. Turn the power off and do not leave the tablesaw until

the blade has come to a complete stop.

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 64A Tablesaw is equipped with a single phase, 115/230 volt motor. It is factory wired for 115 volts, but may be converted to 230 volt operation. Make sure the voltage of your power supply matches the specifications on the motor plate of the Tablesaw.

Grounding Instructions

1. All grounded, cord connected tools:

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. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating less than 150 volts:

This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Figure 1(A). The tool has a grounding plug that looks like the plug illustrated in (A).

A temporary adapter, which looks like the adapter illustrated in Figure 1(B&C), may be used to connect this plug to a 2-pole receptacle as shown in (B) if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. (This

adaptor is not applicable in Canada.)

The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box.

Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.

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.

Use only 3-wire extension cords that have 3prong grounding plugs and 3-pole receptacles that accept the tool’s plug.

Repair or replace damage or worn cord immediately.

Figure 1

3. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating between 150-250 volts, inclusive:

This cord is intended for use on a circuit that has an outlet that looks like the one illustrated in Figure 1(D). The tool has a grounding plug that looks like the plug illustrated in (D). Make sure the tool is connected to an outlet having the same configuration as the plug. No adapter is available or should be used with this tool. If the tool must be reconnected for use on a different type of electric circuit, the reconnection should be made by qualified service personnel and after reconnection, the tool should comply with all local codes and ordinances.

230 Volt Conversion

If 230V single phase operation is desired, follow these instructions:

1. Disconnect tablesaw from power source.

2. Open the motor junction box, and consult

the diagrams affixed to the inside of the junction box cover. These diagrams are also shown in Figures 2 and 3. This saw is supplied with four motor leads that are connected for 115V operation (Figure 2). Reconnect these four motor leads for 230V operation (Figure 3).

3. The 115V attachment plug, supplied with

the saw, must be replaced with a UL/CSA listed plug suitable for 230V operation. Consult an electrician for proper procedures to install the plug. The saw must comply with all local and national codes after the 230V plug is installed.

In all cases (115V or 230V) make certain the receptacle in question is properly grounded. If you are not sure, have a registered electrician check the receptacle.

Figure 2

Extension Cords

If an extension cord is necessary, make sure the cord rating is 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 4 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.

Installation and Assembly

Tools required:

Arbor wrench (supplied) 12mm combination wrench (supplied) 3mm and 4mm hex wrenches (supplied) 8, 10, 14, 15, and 19 mm open-end wrenches Cross point and flat head screwdrivers

Some assembly tips:

1. A bowl should be used to hold hardware.

2. To avoid harming the table saw top, a cloth

should be placed on the floor first.

3. Do not remove wax coating from table until

saw is assembled.

4. Start assembly in the area where saw will be

used. This area should be clean and tidy in order to make it easy to find any dropped fasteners and tools.

5. Unwrap only the hardware packages that

one is working on.

6. A mobile light should be used to illuminate

obscure areas.

7. The use of a ratchet wrench with sockets

and extensions will greatly reduce assembly time.

Remove the protective coating from the saw table surface with a soft cloth moistened with a good commercial solvent. NOTE: Do not use acetone, gasoline, or lacquer thinner to remove the protective coating, as it can damage plastic parts and painted areas. Do not use an abrasive pad on the table top.

Stand Assembly

Note: Except for the rubber feet, only finger tighten all nuts. Stand assembly nuts should be

fully tightened only after the saw has been attached to the stand. If you are using a mobile base, the stand should be tightened only after placing the saw in the mobile base.

TIP: It may be easier to assemble stand in an upside-down position. Illustrations are shown right side-up for the purpose of clarity.

1. Assemble two leg sets using the long cross

braces attached to the inside of the legs. The lower cross braces go into first set of square holes located approximately center of each leg. See Figure 6. [The bottom holes

on the legs are not used for this machine.]

Use (32) 5/16-18 x 5/8 carriage bolts, (32) 5/16 hex nuts, and (32) 5/16 flat washers to assemble the stand.

Figure 6

2. Attach the four short braces to one set of

legs as shown in Figure 6.

3. Complete the stand assembly by attaching

the other set of legs as shown in Figure 7.

4. To attach rubber feet to each leg, first use a

cross-point screwdriver and screw the 1/420 x 1 pan head screw through the recessed hole of the rubber grommet as shown in Figure 8. Push the screw through the hole provided at the bottom of each leg, and tightly fasten down with 1/4 flat washer and 1/4 hex nut.

5. Remember, leave all other stand assembly

nuts only finger tight!

Mounting Saw to Stand

Tip: Remove all contents from carton except

saw and one extension wing. Put some soft padding on floor beside box. Fold back carton flaps and gently roll carton upside down on to padding. Lift off carton, being careful not to let extension wing fall.

1. Place table top upside down with its surface

on a flat floor, and place stand, with legs upside down, atop the cabinet. See Figure 9

Figure 7

2. Align the holes of stand with holes on

bottom flange of saw base and tightly secure with four 5/16-18 x 1 hex head screws, four 5/16 hex nuts, four 5/16 flat washers, and four 5/16 spring washers. The screw heads should be inside of the saw body (see inset, Figure 9).

3. Carefully raise the machine to its upright

position.

4. With the saw located at the place of

operation, (with a solid foundation), spread the stand legs to self-align the machine. (If using an optional mobile base, place the machine onto the base now). When all four legs are seated solidly on the floor (or mobile base), tighten down securely all nuts and screws in the stand assembly.

NOTE: If the saw is to be used without the metal stand provided, care must be taken to provide a hole in the stand or bench used by the operator to facilitate the removal of sawdust.

If there is any tendency to

slide, walk, or tip over during operation, the stand or bench MUST be secured to the floor.
