Operating Your Air Compressor
(continued)
5. Move the choke lever to the CHOKE
position, turn the fuel lever ON, and
turn the engine stop switch to the ON
position.
6. Pull start grip lightly until resistance is
felt, and then pull briskly.
7. As the engine warms up, gradually
move the choke lever to the open posi-
tion. See gas engine manual for more
details.
8. Run the compressor unloaded for
approximately 30 minutes to break in
the pump.
9. After approximately 30 minutes, move
the unloader lever down to the loaded
position and turn the regulator knob
clockwise (See Figures 7 and 8). The
compressor will begin to pump air into
the tank.
When maximum tank pressure is
reached, the compressor automatically
unloads, bringing the engine to idle. The
engine remains at idle until tank pressure
falls to a preset level. The engine then
accelerates and the compressor pumps
additional air into the tank.

In order to maintain efficient operation of
the compressor system, check the air fil-
ter weekly (per maintenance schedule),
oil level and gasoline level before each
use. The ASME safety valve should also
be checked weekly. Pull ring on safety
valve and allow the ring to snap back to
normal position. This valve automatically
releases air if the tank pressure exceeds
the preset maximum. If air leaks after the
ring has been released, or the valve is
stuck and cannot be actuated by the ring,
the ASME safety valve MUST be
replaced.
With engine OFF, clean debris from
engine, flywheel, tank, air lines and
pump cooling fins.
Maintenance
Release all pressure from the
system before attempting to
install, service, relocate or per-
form any maintenance.
!
WARNING
Do not attempt to tamper with
the ASME safety valve!
