SPECIFICATIONS
• RPM: 17,000 free speed
• Operating Air Pressure: 90 psi
• Max Air Consumption: 8 CFM [198 l/m] @90 PSI [6.2 bar]
• Inlet thread size: 1/4” FNPT
• Required Belt Size: 3/4” x 20-1/2”, minimum 17,000 RPM
• Belt Articulation Angle Range: 50°
REQUIRED FOR USE
• The inlet air supply should have a moisture separator capable of removing all moisture and
impurities from the air supply. Moisture and/or oil in the air supply will cause poor tool
performance and damage.
• A suitable regulator must be used to limit incoming air pressure to 90 PSI maximum.
Excessive air pressure can cause permanent damage to the unit and possible serious
personal injury from bursting.
• For best results, a compressor capable of providing a minimum of 8 CFM @ 90 PSI is
recommended. Less available CFM will negatively affect the performance of the
Belt Sander and may overwork the compressor.

INJURY HAZARD!
• This tool has high-speed, abrasive surfaces which can quickly cause injury.
Keep fingers and hands away from moving parts when operating. Wear
thick, well-fitting work gloves and keep loose clothing, sleeves, cords,
jewelry and hair away from moving parts.
• This tool can eject sparks which can ignite flammable materials. Do not
operate near flammable materials and keep all persons and pets away
from the work area.
• Always make sure the workpiece is securely clamped or anchored to avoid
sudden movements which could result in injury.
• Always disconnect tool from air supply when changing Abrasive Belts
or making adjustments to prevent accidental tool starting and potential
severe injury.
• Frequently inspect Abrasive Belt and tool condition. If tears develop,
discontinue tool use immediately and replace damaged belt. ONLY USE
replacement Abrasive Belts rated for 17,000 RPM or greater otherwise
severe injury can result in the event of Belt failure.
VIBRATION INJURY HAZARD!
• This tool will vibrate during use! Repeated exposure to vibration may
cause physical injury.
SET UP & CONNECTION
• Wrap white thread sealing tape (Not Included) around the threads of the included 1/4”
Male NPT quick disconnect fitting, then thread it into the 1/4” NPT inlet threads of the
Belt Sander Body.
• Attach Air Supply to Inlet Fitting.
Be sure that the air supply to the tool is clean and dry. Moisture in the supply
line will quickly damage the air motor and valves.
A minimum 3/8” I.D. air line should be used for optimal performance.

OPERATION
• 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.
INJURY HAZARD!
Disconnect air supply from the tool to prevent accidental starting and potential
injury while installing or removing Abrasive Belts.
ABRASIVE BELT REPLACEMENT
The Abrasive Belts are quickly and easily changed. No tools are required.
The following steps describe how to do this:
• 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 depressing the
Thumb-Lever Latch (FIG 1).
NOTE: The Guide Pin will move inward until it lo-
cates under the Latch portion of the Thumb-Lever
Latch holding it in the retracted position while the
Abrasive Belt is changed (FIG 2).
• Pull the worn Abrasive Belt free of the Drive Drum
and discard.
• Slide the replacement Abrasive Belt over the Drive
Drum and Idle Roller at the end of the Abrasive
Belt Arm (FIG 2).
NOTE: Be sure the Abrasive Belt is slid fully over
the Guide Bar located on the upper surface of the
Abrasive Belt Arm.
• Depress the Thumb-Lever Latch to release the
Guide Pin restoring full spring pressure (FIG 3).

starting and potential
injury while adjust-
ing the Abrasive Belt
Articulation Angle. The
Articulation Adjust-
ment Screw is located
at the outer left side
of the Abrasive Arm
Assembly (FIG 5).
• Using the included 3mm Hex Key, loosen the screw slightly and the outer 2.5” of the arm will
droop and the locking screw head will slide in the curved slot allowing up to 50° of articulation.
NOTE: Spring tension in the Arm must be maintained against the belt to retain it in place or it
will fall off.

adjusting the Abrasive Belt Tracking. The Tracking Adjustment Screw is located at the outer
right side of the Abrasive Arm Assembly (FIG 6).
• Using the included 4mm Hex Key, turn the screw clockwise (as viewed from the right side)
will cause the belt to track left while turning the screw counter-clockwise will cause the belt
to track right.
