TO MALFUNCTION.

MALFUNCTIONS

BEYONDTHE SCOPE OF THIS MANUAL

SHOULD BE BROUGHT TO THE ATTENTlON OF YOUR ARO REPRESENTATIVE

OR RETURN THE

TOOL TO THE FACTORY FOR REPAIR.

LOW SPEED AND POWER OR GRIND- ER WILL NOT RUN.

POSSIBLE CAUSE

1.INADEQUATE AIR SUPPLY.

2.AIR REGULATOR (43157) IMPROPER-

LY ADJUSTED.

3.AIR INLET OR EXHAUST SCREEN PLUGGED.

4.OBSTRUCTION IN THROTTLE VALVE OR VALVE NOT OPENING.

5.MOTOR NOT BEING PROPERLY LU- BRICATED.

5.ROTOR BLADE IS MISSING, INCOR- RECTLY INSTALLED. BADLY WORN OR BEARING FAILURE.

CORRECTIVE ACTION

1.CHECK AIR SUPPLY FOR CORRECT REGULATOR ADJUST- MENT (90 P.S.I.G. MAX. WHEN TOOL IS OPERATING).

2.CHECK REGULATOR ADJUSTMENT TO BE SURE OF MAXIMUM AIR FLOW.

3.INSPECT, WASH CLEAN.

4.DISASSEMBLE THROTTLE, CLEAN, INSPECT FOR OBSTRUC- TlONS OR DAMAGED PARTS.

5.APPLY 2 OR 4 DROPS OF SPINDLE OIL IN AIR INLET. RUN TOOL TO ALLOW OIL TO ENTER MOTOR - BE CERTAIN OILER IS FULL OF OIL.

5.DISASSEMBLE MOTOR, CLEAN AND INSPECT FOR PROPER INSTALLATION, REPLACE BLADES AND/OR BEARINGS IF NEC- ESSARY.
