Overhaul and Maintenance

WARNING

Risk of Serious Injury or Death

Overspeed can result in serious injury or death.

If a speed governor is used, make sure that the correct speed governor is assembled. Careless handling may put it out of order
Do not disassemble security parts and always replace them if they are damaged.
Always do a free speed check of the tool after service.

Perform an overhaul of the tool at six-months intervals. Inspect and maintain the tool more often if it is in heavy duty service or not running correctly.

Clean the motor parts and apply a thin layer of air lubrication oil onto the vanes and inner surface of cylinder and end plates.
Assemble the motor and make sure that it is running free. Add two drops of oil through the air inlet and run the motor at idling speed for 5-10 seconds.

Change the grease in the angle gear after approximately 200 hours of operation. See Lubrication.

Inspect the sealing lip and adjacent column for wear. The seal is essential to keep lubricant in the gear box.

Clean the strainer at the air inlet frequently to prevent clogging and decreased capacity.
