NOTE: See "Operation" section for the location of controls.
To ensure efficient operation and longer life of the air compressor unit, a routine
maintenance schedule should be prepared and followed. The following routine
maintenance schedule is geared to a unit 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
units in an extremely dirty and/or hostile environment will require a greater
frequency of all maintenance checks.
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 Check Safety Valve
If the safety valve
does not work
properly, over-pressurization may
occur, causing air tank rupture or
an explosion.

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.
