2-9. OPERATING PROCEDURES. - Continued.
a. Starting. - Continued.
(d)
Put the release lever of the unloader valve (3) into the up position to release all internal compressed
air that may be in the system.
(e)
Position fuel tank three way fuel valve (4) to position arrow on valve handle toward belt guard.
(f)
Position fuel filter handle (5) into down position.
(g)
Slowly pull out starting handle (7) until you feel resistance, and then return it to the initial position.
CAUTION
Do not allow the handle grip to snap back. Return it gently to prevent damage to the starter.
(h)
Hold recoil starting handle (7) firmly and pull out the handle briskly. Engine will start and go to
maximum operating speed.
NOTE
If engine does not start on first pull, repeat steps (c), (g), and (h).
(i)
Put the lever of the unloader valve (3) in the horizontal position to allow the system to become
pressurized.
b. Adjusting Speed. After engine has been started, the engine speed must not be adjusted. The engine must run
at full throttle to allow the air compressor unit to provide the maximum available rate of compressed air.
c. Stopping. When the air compression operation is complete, the air compressor unit must be shutdown by
stopping the engine. To shutdown the air compressor unit, perform the following steps.
(Refer to Figure 2-5.)
CAUTION
Do not stop engine suddenly since it may cause the temperature to get too high and cause possible damage to
the engine. When stopping the engine, reduce the load slowly and allow the engine to run at idle speed for 3
minutes before stopping engine.
Do not stop engine with the decompression lever as engine damage may result. If the engine cannot be stopped
by the speed control lever knob, then move the handle on the fuel filter to the up position to cut off fuel flow to
the engine.
Be careful when loosening speed control knob because its spring loaded mechanism will automatically pull the
speed control knob to STOP position. Grip the speed control knob firmly as it is being loosened.
