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 work-
ing environment. Compressor outfits in an extremely dirty and/or hostile environment will require a greater fre-
quency of all maintenance checks.
NOTE: See "Operation" section for the location of controls.
To Check Safety Valve
If the safety valve does
not work properly, over-
pressurization may occur, causing air tank
rupture or an explosion. Before starting com-
pressor, 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
1. Set the On/Auto/Off lever to "OFF".
2,
3.
4.
5,
Pull the regulator knob out and turn clockwise to
set the outlet pressure to zero.
Remove the air tool or accessory.
Pull ring on safety valve allowing air to bleed from
the tank until tank pressure is approximately 20
psi. Release safety valve ring.
Drain water from air tank by opening drain valve
(counter-clockwise) on bottom of tank.
Water will condense in
the air tank. If not
drained, water will corrode and weaken the air
tank causing a risk of air tank rupture.
6. After the water has been drained, close the drain
valve (clockwise). The air compressor can now
be stored.
NOTE: If drain valve is plugged, release all air pressure.
The valve can then be removed, cleaned, then rein-
stalled.
Air Filter - Inspection and Replacement
Hot surfaces. Risk of
burn. Compressor heads
are exposed when filter cover is removed.
Allow compressor to cool prior to servicing.
Keep the air filter clean at
all times. Do not operate
the air compressor with the air filter removed.
A dirty air filter will not allow the compressor pump to
operate at full capacity. Before you use the compres-
sor pump, check the air filter to be sure it is clean and
in place.
if it is dirty, replace it with a new filter. On some mod-
els,the filter may be removed by using a pair of needle
nose pliers or a screwdriver. Pull or pry out the old fil-
ter and carefully clean the filter area. Push in the new
air filter.
