ESS GPS-5 OWNER’S MANUAL
Compressor
The compressor produces pressurized air which is used to atomize and
propel the liquid spray. The oil level should be checked before each
spray application. Use only 30-weight compressor oil in the compres-
sor. Follow the Maintenance Schedule on page 10 for periodic engine
maintenance procedures.
NOTE:
The GPS-5 engine and compressor
become hot during normal use.
To check the compressor oil, remove the 7/16” oil ll plug. Oil level
should be up to the lip of the hole.
Compressor air lter
The compressor has an air intake lter located on the front side of the
compressor. This lter should be checked regularly. If it gets clogged,
it will cause the compressor to overheat. Take note of the conditions
you are spraying in. The lter will need to be cleaned more often if it’s
dusty.
