Solution
Check the air pressure at the Inlet. The pressure
must not exceed 90 psig (6.2 bar/620 kPa).
Clean the Screen in a clean, suitable, cleaning
solution. If it cannot be cleaned, replace it.
Never operate a Sander or Polisher without an
Inlet Screen. Ingestion of dirt into the Sander
or Polisher can, in some cases, cause an unsafe
condition.
Replace the complete set of Vanes.
Replace the Cylinder if it is worn or broken or if
the bore is scored or wavy.
Lubricate the Sander or Polisher as instructed in
LUBRICATION.
If lubrication does not result in
satisfactory operation, disassemble the motor,
inspect and clean all parts.
Examine each Bearing. Replace the Rear Rotor
Bearing Seal Assembly if worn or damaged or
replace the Front Rotor Bearing.
Mount the Arbor on centers. Check the bearing
diameter runout with an indicator. Replace the
Arbor if runout exceeds .002" Total Indicator
Reading.
Make certain that all motor parts are properly
aligned prior to clamping the motor assembly.
Replace worn parts.
Tighten the Plug. If the problem persists, replace
it.
