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.

Release all pressure from the system before attempting to install, service, relocate or per- form any maintenance.

Do not attempt to tamper with the ASME safety valve!

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	Figure 9
ring has been released, or the valve is
stuck and cannot be actuated by the ring,

replaced.

With engine OFF, clean debris from engine, flywheel, tank, air lines and pump cooling fins.
