SECTION 7 - MAINTENANCE

Proper maintenance is important in order to ensure safe, economical, and 
trouble-free operation.    Improper maintenance may cause the air compressor 
to malfunction and can lead to serious injuries or death.

Shut off the compressor before performing any maintenance.  
When the engine is running, make sure the area is 
well ventilated.  The compressed air may contain harmful 
vapours or particles.

Use authorized parts or their equivalent.  The use of replace-
ment parts which are not equivalent quality may damage the 
compressor.

NOTE: Some of these maintenance techniques can be danger-
ous and must be performed by a qualified technician.

In order to maintain high performance and extend the service life of the com-
pressor, periodical inspection and adjustments should be done based on the 
following maintenance schedule:
