SETUP
NOTE:
The engine is shipped without oil. Add oil before use. It is recommended
that you change the oil as described in your engine owner’s manual maintenance
schedule. Always check the oil level before starting engine. (See engine owner’s
manual for oil and fuel recommendations.)
STARTING
ENGINE
1. Turn fuel valve to the “ON” position.
2. Flip the engine switch to the “ON” position.
3. Place foot on base, grasp starter handle, and start engine as you would a
lawn mower. Use choke if necessary.

UNLOADER
VALVE
1. Move to “UNLOAD” position
2. Start engine
3. Return to “PRESSURIZE” position
When STARTING the engine with air pressure in the tanks (i.e. after refueling,
etc.), manually unload the compressors by moving the valve to the “UNLOAD”
position, starting the engine, and then moving the valve back to the “Pressurize”
position. This allows the compressors to turn freely (exhaust to atmosphere)
without the back pressure of the tanks. To clean vent, remove the nut containing
screen and filter with a 11/16”hex wrench. Hold under running tap water with
nut toward faucet. Shake out excess water and reinstall.
OPERATION
The engine will start with the control lever in the “FAST’ position and will
compress air until the tank pressure reaches 135 PSI. When the tank pressure
reaches 135 PSI, the unloader valve will automatically actuate the throttle
control causing the engine to run at idle speed, and vent the compressed air
to atmosphere. When the tank pressure drops to 115 PSI, the unloader valve
will reactuate the throttle control, causing the engine to run at high speed, and
redirect the compressed air to the tank.
WARNING:
Before using air tools or accessories, check manufacturer’s
maximum pressure rating. Maximum pressure rating must be above 135
PSIG.
STOPPING
1. Flip the engine switch to the “OFF’ position.
2. Release air from tank.
3. Drain water from both tanks.
4. Turn fuel valve to “OFF” position.
5. Drain excess gas if compressor is to be stored indoors. (see engine owners
manual).
