Maintenance
WARNING!
Disconnect spark plug wire from spark plug and release air pressure from system before performing
maintenance.
NOTE:
All compressed air systems contain maintenance parts (e.g. lubricating oil, filters, separators) which are
periodically replaced. These used parts may be, or contain, substances that are regulated and must be disposed
of in accordance with local, state, and federal laws and regulations.
NOTE:
Take note of the position and locations of parts during disassembly to make reassembly easier. The
assembly sequences and parts illustrated may differ for your particular unit.
Daily or before each
operation

DRIVE BELT
Belts will stretch in normal use. Properly adjusted, a
5 pound force applied to the belt between the motor
pulley and the pump will deflect the belt about 1/2”.
TO ADJUST DRIVE BELT:
1. Remove belt guard.
2. Loosen the four fasteners holding the engine to
the compressor.
3. Shift the engine in the proper direction. The belt
must be properly aligned when adjustment is made.
4. To align belt, visually center engine pulley to
compressor pulley.
6. If necessary, move the pulley on the engine
shaft.
7. Check for proper belt tension (see diagram).
8. Tighten the four fasteners holding the engine to
the top plate.
9. Attach belt guard.
