READ INSTRUCTIONS
• Thoroughly read and understand these product instructions before using
this tool. Failure to follow all warnings can result in tool damage or serious
physical injury.
• Keep these product instructions for future reference.
HEALTH AND INJURY HAZARDS!
• This tool has high-speed, highly abrasive surfaces which can quickly cause
severe injury. Keep fingers and hands away from moving parts when operat-
ing. Wear thick, well-fitting work gloves and keep loose clothing, sleeves,
cords, jewelry and hair away from moving parts.
• Hazardous dust is generated during the grinding/sanding process.
Wear appropriate NIOSH approved respiratory protection.
• Metal particles and dust can be ejected during the grinding/sanding process.
Always wear ANSI approved eye and ear protection when operating this tool.
• Do not force tool or exert side forces on belt drive while grinding or sanding
as the tool body can suddenly kick back or twist causing severe hand or
wrist injury. Belts can also be torn with excessive side force causing them
to disintegrate and eject sharp pieces at high velocity.
• This tool will vibrate during use! Repeated exposure to vibration may
cause physical injury.
• Always disconnect tool from air supply when changing abrasive belts to
prevent accidental tool starting and potential serious injury.
• Always make sure the workpiece being sanded/ground is securely clamped
or anchored to avoid sudden movements which could result in injury.
• Frequently inspect belt condition. If tears or holes develop, discontinue tool
use immediately and replace damaged belt. ONLY USE replacement belts
rated for 16,000 RPM or greater use otherwise serious injury or death can
result in the event of belt failure.
CUT HAZARD!
• Handling sharp metal can cause cuts. Wear thick work gloves and
long sleeves when using this tool.
EXPLOSION HAZARD!
• Do not exceed 90 psi (6.3 bar) of tool inlet pressure. Permanent tool
damage and/or explosion could occur and cause personal injury.

SET-UP & CONNECTION
1. Be sure that the air supply to the tool is clean and dry. Moisture in the supply line will quickly
damage the motor and valves.
2. A minimum 3/8” I.D. air line should be used for optimal performance.
3. Thread the included 1/4" Male Quick-Disconnect Fitting into the tool using TFE thread sealing
tape (not included).
OPERATION
• Rotate the lever located at the left rear of the tool handle to regulate motor speed (FIG 1).
Note that the “down” position will result in slower speed while “up” will increase speed.
• Depress Throttle Paddle inward with fingers to operate tool..
• Keep the broad work surface of the Abrasive Belt parallel to the work surface whenever
possible to minimize uneven wear and maximize usable life.
• Always maintain a firm grip while operating tool, do not force but allow the rotational speed
of the Abrasive Belt to do the work.
• Be sure that the workpiece is clamped down or held securely to minimize the danger of
injury while operating tool.

ABRASIVE BELT REPLACEMENT
The Abrasive Belts are quickly and easily changed. No tools are required.
The following steps describe how to do this:

the tool to prevent acciden-
tal starting and potential
injury while removing or
installing an Abrasive Belt.
2. The end of the Abrasive
Belt Arm is spring loaded to
keep the proper tension on
the Abrasive Belts. While
holding the tool firmly, push
inward on the end of the
Abrasive Belt Arm while de-
pressing the Thumb-Lever
Latch (FIG 2).
NOTE: The Guide Pin will
move inward until it locates
under the Latch portion
of the Thumb-Lever Latch
holding it in the retracted
position while the Abrasive
Belt is changed (FIG 3).
3. Pull the worn Abrasive Belt
free of the Drive Drum and
discard.
4. Slide the replacement
Abrasive Belt over the
Drive Drum and Idle Roller
at the end of the Abrasive
Belt Arm (FIG 4).
NOTE: Be sure the Abrasive
Belt is slid fully over the
Guide Bar located on the
upper surface of the
Abrasive Belt Arm.
5. Depress the Thumb-Lever Latch to release the Guide Pin restoring full spring pressure.
