Customer Responsibilities
Check Safety Valve
Drain Tank
Air Filter
Air compressor pump intake and exhaust valves
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
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. Pull the regulator knob out and turn counter-
clockwise to set the outlet pressure to zero.
3. Remove the air tool or accessory.
4. Pull ring on safety valve allowing air to bleed from
the tank until tank pressure is approximately 20
psi. Release safety valve ring.
5. Drain water from air tank by opening drain valve
(counter-clockwise) on bottom of tank.
drained, water will corrode and weaken the air
tank causing a risk of air tank rupture.

are exposed when filter cover is removed.
Allow compressor to cool prior to servicing.
A dirty air filter will not allow the compressor to oper-
ate at full capacity. Keep the air filter clean at all
times.
1. Remove the air filter retainer.
2. Remove the air filter and make sure it is clean.
IMPORTANT: Do not operate the compressor with
the air filter removed.
