OPERATING INSTRUCTIONS
WARNING
RISK OF BODILY INJURY!
Never assume the air com-
pressor is safe to work on just
because it is not operating. It
could restart at any time!
*The pump oil must be changed after the first 50 hours of operation and every 200 hours or 3 months, whichever
comes first. In harsh environments, maintenance must be performed on a more accelerated schedule.
Every  years, an Authorized Service Technician should check the check valve, intake valves and delivery valves.
