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.

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 Backing Pad or

SET-UP
• Rotate the Eccentric Drum and Arbor so that the 1/8” [3mm] hole in the upper side aligns with
the slotted opening in the Arbor Guard.
• Place the smaller end of the cylindrical Arbor Key through the slotted opening in the Arbor
Guard and into the 1/8” [3mm] hole of the Eccentric Drum.
• Thread the shank of the Backing Pad into the Arbor.
• Using a good quality Teflon sealing tape (Not Included), thread the 1/4” MNPT, Male quick
disconnect inlet fitting into the air inlet.
CONNECTION
• 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.

OPERATION
• Place a Hook and Loop Sanding Disc onto the face of the Backing Pad.
• Connect air supply, move throttle safety lever forward and depress trigger to begin rotating
action. Speed is regulated by pressure applied to the trigger.
MAINTENANCE
• Add several drops of air tool oil before each use by dropping directly into the air inlet.
• If tool is to be unused for an extended period, add 10 drops of air tool oil directly to the air inlet,
then store the tool, handle up.
