MAINTENANCE & STORAGE
STORAGE
If it is necessary to store the tool for an extended period of time, apply a generous
amount of lubrication before storing. The tool should be run for approximately 30
seconds in order to ensure that the lubrication is evenly distributed throughout the tool.
The tool should be stored in a clean and dry environment.
TROUBLESHOOTING
WARNING: If any of the following symptoms appears while operating the tool, stop
using the tool immediately, or serious personal injury could result. Only an authorized
service centre should perform repairs on this tool. Disconnect the electrical plug and
disconnect any tools from air supply before attempting any adjustment.
NOTE: Troubleshooting problems may have similar causes and solutions.
PROBABLE CAUSE
 Motor parts are worn.
 The cam clutch is worn or
sticking due to insufficient
lubrication.
 Dirt particles have gotten
jammed in motor.
 The power regulator is in the
closed position.
 The air flow is blocked by
dirt.
 One or more of the motor
vanes is stuck due to
material build-up.
 The throttle valve O-rings
have dislodged from the
seat in the inlet valve.
CORRECTIVE ACTION
 Lubricate the clutch housing.
 Check for excess clutch oil. Clutch cases should only be
filled halfway. Overfilling may cause drag on high-speed
clutch parts. A typical oiled/lubricated air tool requires
1⁄2 oz (15 ml) of oil.
GREASE/LUBRICATION NOTE: Heat usually indicates
insufficient grease in the chamber. Harsh operating
conditions may require more frequent lubrication.
 Check the air inlet filter for blockage.
 Pour air tool lubricating oil into the air inlet, as per
instructions.
 Operate the tool in short bursts, quickly reversing
rotation back and forth, where applicable.
 Repeat above as needed.
 Pour air tool lubricating oil into the air inlet.
 Operate the tool in short bursts, quickly reversing
rotation back and forth, where applicable.
 Tap the motor housing gently with a plastic mallet.
 Disconnect the sander from the air supply. Free the
motor by rotating the drive shank manually, where
applicable.
 Replace the O-rings.
