MAINTENANCE

NOTE: Qualified service personnel should perform any service procedure not covered in the main-
tenance schedule below.
ITEMS TO CHECK/CHANGE
Check Tank Safety Valve
Overall Unit Visual Check
Check Air Filter (more frequently in dusty or humid environments)
To ensure efficient operation and longer life of the air compressor unit, a routine maintenance
schedule should be followed. The following schedule is geared toward a consumer whose compressor is used in a
normal working environment on a daily basis. If necessary, the schedule should be modified to suit the condition
under which your compressor is used. The modifications will depend upon the hours of operation and the working
environment. Air compressors used in an extremely dirty and/or hostile environment will require a greater frequency
of all maintenance checks.
STORAGE
For storing the air compressor, be sure to do the following:
1. Turn the unit off and unplug the power cord from the receptacle.
2. Remove all air hoses, accessories, and air tools from the air compressor.
3. Perform the daily maintenance schedule.
4. Open the drain valve to bleed all air from the tank.
5. Close the drain valve.
6. Store the air compressor in a clean and dry location.
The air compressor should be turned off and unplugged from the power source before any
maintenance is performed as well as the air bled from the tank and the unit allowed time to cool. Personal injuries
could occur from moving parts, electrical sources, compressed air or hot surfaces.

TROUBLESHOOTING GUIDE

The air compressor should be turned off and unplugged from the power source before any maintenance is performed as well as
the air bled from the tank and the unit allowed time to cool. Personal injuries could occur from moving parts, electrical sources,
compressed air, or hot surfaces.
Problem
Air leaks at the check valve or
at the pressure relief valve.
Air leaks between head and
cylinder.
Possible Cause & Corrective Action
A defective check valve results in a constant air leak at the pressure release valve
when there is pressure in the tank and the compressor is shut off. Drain the tank,
then remove and clean or replace the check valve.
Be sure of proper torque on head bolts. If leak remains, contact a service
technician.
