1. Prior to use, the Polisher requires the attachment of a 1/4” - 18 NPT Quick Con-
nector (not included) to its Inlet Bushing (13). To do so, make sure the screen
Air Filter is properly seated in the Inlet Bushing. Wrap approximately 3” of pipe
thread sealer tape (not included) around the male threads of the Quick Connec-
tor. Then, rmly tighten the Quick Connector into the Inlet Bushing.

OPERATING INSTRUCTIONS
WARNING! Use eye and hearing protection. Always wear ANSI-approved safety
impact glasses and full face shield when using this Polisher Kit. Also, wear ANSI
approved hearing protection. Other people in the work area must also wear ap-
propriate ANSI approved safety equipment.
Whenever possible, secure the workpiece in place, using a vise or clamps (not1.
included).
Prior to polishing a workpiece, make sure its surface has been thoroughly2.
cleaned and is free of dust, dirt, oil, grease, etc.
Apply about two tablespoons of wax (not included) evenly on the previously3.
installed Foam Pad (31). Do not apply the wax directly on the surface of the
workpiece. The amount of wax needed will vary according to the size of the
workpiece being polished. NOTE: Avoid using too much wax. For additional
applications of wax to the Foam Pad, reduce the amount of wax. The Foam Pad
will not absorb as much wax in subsequent applications. (See Figure C.)
Connect the air supply hose (not included) to the previously installed Quick Con-4.
nector on the Polisher. Always position the air hose so it will not damage the
surface being worked on. Turn on the air compressor, and set its regulator at 90
PSI. Do not exceed 90 PSI. (See Figure C.)
IMPORTANT:5. Always start and stop the Polisher while it is held rmly against
the surface of the workpiece. Failure to do so may result in the Foam Pad (31)
being thrown from the 3” Pad (29). (See Figure C.)
Grip the Polisher rmly with both hands. Then, squeeze the Trigger (8) to start 6.
the Polisher. NOTE: The speed of the Polisher may be increased by turning its
Regulator (14) counterclockwise. (See Figure C.)
Allow the Foam Pad (31) to spin up to full speed. Then begin applying wax to the7.
workpiece. Apply the wax to all at surfaces with broad, sweeping strokes in a
criss-cross pattern. Apply the wax evenly over the surface of the workpiece, and
add additional wax as needed. (See Figure C.)
After the wax has been applied to the workpiece surface, release pressure on the8.
Trigger (8) to turn off the Polisher. Turn off the air compressor. Then squeeze
the Trigger of the Polisher to release any remaining air pressure in the tool and
compressed air system. (See Figure C.)
Remove the Foam Pad (31) from the 3” Pad (29) of the tool. With the Foam Pad9.
in your hand, apply the wax to all hard to reach areas of the workpiece.
(See Figure C.)
Allow sufcient time for the wax to dry on the workpiece surface.10.

SKU 95030 For technical questions, please call 1-800-444-3353. PAGE 7
Install the Bufng Pad (32) onto the 3” Pad (29). 11. (See Figure C.)
Connect the air supply hose to the Quick Connector on the Polisher. Turn on the12.
air compressor, and set its regulator at 90 PSI. Do not exceed 90 PSI.
(See Figure C.)
IMPORTANT:13. Always start and stop the Polisher while it is held rmly against
the surface of the workpiece. Failure to do so may result in the Bufng Pad (32)
being thrown from the 3” Pad (29). (See Figure C.)
Grip the Polisher rmly with both hands. Then, squeeze the Trigger (8) to start 14.
the Polisher. NOTE: The speed of the Polisher may be increased by turning its
Regulator (14) counterclockwise. (See Figure C.)
Allow the Bufng Pad (32) to spin up to full speed. Then begin polishing the 15.
workpiece surface by lightly bufng off the wax residue in a circular pattern. Con-
tinue polishing until all the wax residue is removed. (See Figure C.)
After the wax has been removed from the workpiece surface, release pressure16.
on the Trigger (8) to turn off the Polisher. Turn off the air compressor. Then
squeeze the Trigger of the Polisher to release any remaining air pressure in the
tool and compressed air system. (See Figure C.)
Remove the Bufng Pad (32) from the 3” Pad (29) of the tool. With the Bufng 17.
Pad in your hand, remove the wax from all hard to reach areas of the workpiece.
(See Figure C.)
INSPECTION, MAINTENANCE, AND CLEANING
WARNING! Always wear ANSI-approved safety impact goggles when performing
any inspection, maintenance, or cleaning procedures.
WARNING! Prior to performing any inspection, maintenance, or cleaning of the Pol-
isher Kit, make sure to disconnect the air hose from the tool. Then, squeeze the
Trigger (8) again to release any compressed air in the system and tool.
Before each use:1. Inspect the general condition of the Polisher Kit. Check for
misalignment or binding of moving parts, damaged parts, and any other condition
that may affect the tool’s safe operation. If abnormal noise or vibration occurs,
have the problem corrected before further use.
Do not use damaged tools and equipment.
NOTE:2. The most common error when polishing a workpiece is applying too
much wax. If the Foam Pad (31) becomes too saturated with wax, polishing will

SKU 95030 For technical questions, please call 1-800-444-3353. PAGE 8
be more difcult and will take longer. Applying too much wax may also reduce
the life of the Foam Pad. If the Foam Pad continually comes off the 3” Pad (29)
during use, too much wax has been applied.
To clean the Polishing Kit:3. Wipe the exterior of the Polisher with a clean, damp
cloth, using a mild detergent. Do not immerse the tool in liquids. The Foam Pad
(31) and Bufng Pad (32) may be washed and dried at medium heat.
When storing:4. Always store the Polishing Kit in a clean, dry, safe location out of
reach of children. Always remove the Foam Pad (31) and Bufng Pad (32) from
the Polisher when not in use. This will allow the pads to dry and retain their origi-
nal shape. To prolong the life of the pads, store the pads face up.
CAUTION!5. All maintenance, service, and repairs not mentioned in this manual
must only be performed by a qualied service technician.
