Risk of unsafe operation. Unit cycles automatically when
power is on. When performing maintenance, you may be exposed to voltage
sources, compressed air, or moving parts. Personal injuries can occur. Before
performing any maintenance or repair, disconnect power source from the
compressor and bleed off all air pressure.
To ensure efficient operation and longer life of the air compressor outfit, a routine
maintenance schedule should be prepared and followed. The following routine
maintenance schedule is geared to an outfit in a normal working environment
operating on a daily basis. If necessary, the schedule should be modified to suit the
conditions under which your compressor is used. The modifications will depend
upon the hours of operation and the working environment. Compressor outfits in
an extremely dirty and/or hostile environment will require a greater frequency of all
maintenance checks.
NOTE: See Operation section for the location of controls.

TO CHECk SAFETY VALVE

Risk of bursting. If the safety valve does not work properly,
over-pressurization may occur, causing air tank rupture or an explosion.
Risk from flying objects. Always wear certified safety equip-
ment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side shields.
1. Before starting compressor, pull the ring on the safety valve to make sure
that the safety valve operates freely. If the valve is stuck or does not operate
smoothly, it must be replaced with the same type of valve.
