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.

SAVE THESE INSTRUCTIONS.

DO NOT DESTROY.
