TOOL SET UP

INSTALLING A GRINDING WHEEL

1. The Grinding Wheel MUST be:

• Rated to at least 3600 RPM.

• No larger than 3″ (76.2 mm) in diameter.

• Fitted with a 1/2″ round arbor hole.

• 1/2″ Thick or less.

• Suitable for edge grinding, not surface grinding.

• Dry and clean.

• Proven undamaged by inspection.

2. Loosen Screws on Grinding Wheel Cover.

Twist cover clockwise and remove.

3. Hold onto wheel to stop wheel from turning.

Turn Nut counterclockwise to remove.

4. Remove Outer Flange.

Keep Wheel Bushing (5) and Inner

Flange (7) in position on Spindle.

5. Closely inspect the wheel before installing.

6. For wheels with paper gaskets (blotters) or metal gaskets: Slip the grinding wheel onto

the Spindle with the gasket first. The gasket should be centered on the grinding wheel

and the wheel and gasket should rest flat against the Inner Flange.

WARNING: To prevent serious injury, gaskets must be used for all grinding

wheels they are provided with. Gaskets help prevent grinding wheel damage

and wheel slippage, causes of wheel failure.

7. Replace Outer Flange onto Spindle. Wrench tighten Nut only enough so that the

wheel is securely held on the spindle.

WARNING: To prevent serious injury, do not overtighten flange. Overtightening

can damage the wheel, causing wheel failure.

8. Replace Grinding Wheel Cover. Twist cover counterclockwise then tighten hardware

securely.

9. Practice on a sample workpiece before grinding the actual workpiece. Experience is

required to attain good grinding results.

TO PREVENT SERIOUS INJURY FROM ACC IDENTAL OPERATION:

Turn the Power Switch of the tool off and unplug the tool from its electrical outlet before

performing any procedure in this section. Installing a Grinding Wheel

INSTALLING A BUFFING WHEEL

1. Loosen Screws on Buffing Wheel cover.

Twist Grinding Wheel Cover counterclockwise

to remove.

2. Hold onto wheel to stop wheel from turning.

Turn Nut clockwise to remove.

3. Remove Outer Flange.

Keep Wheel Bushing (5) and Inner Flange (7)

in position on Spindle.

4. Slip the Buffing Wheel onto the Spindle.

5. Replace Outer Flange onto Spindle. Wrench

tighten Nut only enough so that the wheel is

securely held on the spindle.

6. Replace Buffing Wheel Cover. Twist cover

clockwise then tighten hardware securely.

7. Practice on a sample workpiece before buffing

the actual workpiece. Experience is required

to attain good buffing results.

WORKPIECE AND WORK AREA SET UP

1. Designate a work area that is clean and well-lit. The work area must not allow access

by children or pets to prevent distraction and injury.

2. Route the power cord along a safe route to reach the work area without creating a

tripping hazard or exposing the power cord to possible damage. The power cord must

reach the work area with enough extra length to allow free movement while working.

3. There must not be objects, such as utility lines, nearby that will present a hazard while

working.

GENERAL OPERATING INSTRUCTIONS

GRINDING

1. Make sure Switch is in OFF-position, then plug in the tool.

2. Turn on the tool.

3. Allow the tool to come up to full speed before touching the wheel.

4. Apply the workpiece to the wheel, allowing the tool to operate at full speed. If the tool

bogs down, use lighter pressure.

5. To create a smoother surface, keep the workpiece moving over the wheel.

6. To prevent accidents, turn off the tool and unplug the tool from its electrical outlet after

use. Clean, then store the tool indoors out of children’s reach.

Note: Adjust distance between wheel and work rest to maintain 1/16″ separation as the

diameter of the wheel decreases with use.

BUFFING

1. Apply the desired polishing compound (coarse or fine) onto the Buffing Wheel.

2. Make sure Switch is in OFF-position, then plug in the tool.

3. Turn on the tool.

4. Using two hands, firmly hold the workpiece and gently move it into contact with the

Buffing Wheel. To avoid kickback and other hazards, only buff on the lower quarter

of the wheel. Note the directional arrows on the front of the Buffer.

CLEANING, MAINTENANCE, AND LUBRICATION

5 .Every few minutes, check the condition and wear of the Buffing Wheels. Replace a

Buffing Wheel when it is worn or damaged.

6. When buffing is finished, remove the workpiece from the Buffing Wheel before

turning Buffer OFF.

7. To prevent accidents, turn off the tool and unplug the tool from its electrical outlet

after use. Clean, then store the tool indoors out of children’s reach.

Note: Move the workpiece with the direction of the wheel, using a medium to hard

pressure.

Note: The correct pressure must be applied to the workpiece to provide the best finish.

Inadequate pressure will result in no significant change in the workpiece. Excessive

pressure may slow down the action of the Buffing Wheel as well as cause uneven

marks on the workpiece.

Note: Adjust distance between wheel and work rest to maintain 1/16″ separation as

the diameter of the wheel decreases with use.

1. BEFORE EACH USE, inspect the general condition of the tool. Check for:

• Loose hardware,

• Misalignment or binding of moving parts,

• Cracked or broken parts,

• Damaged electrical wiring, and

• Any other condition that may affect its safe operation.

2. AFTER USE, wipe external surfaces of the tool with clean cloth. To clean Buffing

Wheel, hand wash and air dry using only mild detergents. Do not immerse any

part of the tool in liquid.

3. If Buffing Wheel has become too hard, use a stiff wire brush (not included) to fluff it up.

4. WARNING! If the supply cord of this power tool is damaged, it must be replaced only

by a qualified service technician.

CAUTION! Only apply the workpiece to the area of the Buffing Wheel that is

rotating away from the workpiece. Objects can be thrown forcefully away from

a Buffing Wheel causing serious injury. Note the directional arrows on the front

of the Buffer, and work only on the lower quarter of the Buffing Wheel.

1. Handle accessories carefully to prevent dropping or bumping. Do not use wheels

that have been dropped or bumped.

2. Store accessories in shelves, racks, boxes, or drawers. Keep storage area dry and

above freezing. Any grinding wheels exposed to humidity or freezing temperatures

must not be used.

ACCESSORY STORAGE AND HANDLING

TROUBLESHOOTING

Problem Possible Causes Likely Solutions

Tool will not start. 1. Cord not connected.

2. No power at outlet.

3. Tool’s thermal reset breaker

tripped (if equipped).

turn off tool and check circuit breaker.

If breaker is tripped, make sure circuit is right

capacity for tool and circuit has no other loads.

3. Turn off tool and allow to cool.

Press reset button on tool.

4. Have technician service tool.

Tool operates

slowly.

Extension cord too long or

wire size too small.

Eliminate use of extension cord.

If an extension cord is needed, use one

with the proper diameter for its length and

load. See Table A on page 3.

Performance

decreases

over time.

Carbon brushes worn or damaged. Have qualified technician replace brushes.

Excessive noise

or rattling.

Internal damage or wear. (Carbon

brushes or bearings, for example.)

Have technician service tool.

Overheating. 1. Forcing machine to work too fast.

2. Blocked motor housing vents.

3. Motor being strained by long or

small diameter extension cord.

1. Allow machine to work at its own rate.

2. Wear ANSI-approved safety goggles and

NIOSH-approved dust mask/respirator while

blowing dust out of motor using compressed air.

3. Eliminate use of extension cord.

If an extension cord is needed, use

one with the proper diameter for its
