Risk of Unsafe
Operation. Unit
cycles automatically when power
is on. When servicing, you may
be exposed to voltage sources,
compressed air, or moving parts.
Before servicing unit unplug or
disconnect electrical supply to
the air compressor, bleed tank
of pressure, and allow the air
compressor to cool.
To ensure efficient operation and lon-
ger life of the air compressor, a routine
maintenance schedule should be pre-
pared and followed. The above routine
maintenance schedule is geared to an
air compressor in a normal working
environment operating on a daily basis.
If necessary, the schedule should be
modified to suit the conditions under
which your air compressor is used.
The modifications will depend upon
the hours of operation and the work-
ing environment. Compressors in an
extremely dirty and/or hostile environ-
ment 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 equipment:
ANSI Z87.1 eye protection (CAN/
CSA Z94.3) with side shields.
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.
TO DRAIN TANK
Risk of unsafe
operation. Air tanks
contain high pressure air. Keep face
and other body parts away from
outlet of drain. Use eye protection
[ANSI Z87.1 (CAN/CSA Z94.3)] when
draining as debris can be kicked up
into face.
Risk from noise.
Use ear protection
(ANSI S12.6 (S3.19) as air flow noise
is loud when draining.
