Safety Setup 9. When the Gas Engine is started and running, the compressor Pump starts compressing air into the Air Tank. Open the in-line Shutoff Valve and adjust the Pressure Regulator (sold separately) so that the air output is enough to properly power the tool, but the 9 output will not exceed the tool's maximum air pressure at any time. Turn the knob clockwise to increase the pressure and counterclockwise to decrease pressure. Adjust the pressure gradually, while checking the air output gauge to set the pressure. IMPORTANT: Allow the engine to run for five minutes with no load after each start‑up so that the engine can stabilize. Maintenance Break-in Period: Breaking-in the engine will help to ensure proper equipment and engine operation. The maintenance break‑in period will last about 20 hours of use. After this period, change the engine oil. Under normal operating conditions, subsequent maintenance follows the schedule explained in the MAINTENANCE AND SERVICING section. Note: When maximum tank pressure is reached, the compressor automatically disengages, and the engine RPM drops down to idle speed. The engine remains at idle until Air Tank pressure falls to a preset level. The Gas Engine will then accelerate and air pressure once again begins to build up in the Air Tank. Note: As long as the engine is running, the operation of the Air Compressor is automatic, controlled by an internal pressure switch. IMPORTANT: The internal pressure switch is not user adjustable; do not make changes to the air pressure settings of the internal pressure switch. Any change to the automatic pressure levels may cause excess pressure to accumulate, causing a hazardous situation. Note: Depressurization - If it is necessary to quickly depressurize the Compressor, turn OFF the engine. Then, pull on the ring on the tank Safety Valve to release stored air pressure. 10.

9.
When the Gas Engine is started and running, the
compressor Pump starts compressing air into the Air
Tank. Open the in-line Shutoff Valve and adjust the
Pressure Regulator (sold separately) so that the air
output is enough to properly power the tool, but the
output will not exceed the tool’s maximum air pressure
at any time.
Turn the knob clockwise to increase the
pressure and counterclockwise to decrease pressure.
Adjust the pressure gradually, while checking
the air output gauge to set the pressure.
IMPORTANT:
Allow the engine to run for five minutes with no load
after each start-up so that the engine can stabilize.
Maintenance Break-in Period:
Breaking-in the engine will help to ensure proper equipment and engine operation.
The
maintenance
break-in period will last about 20 hours of use.
After this period, change the engine oil.
Under normal operating conditions, subsequent maintenance follows the schedule
explained in the MAINTENANCE AND SERVICING section.
Note:
When maximum tank pressure is reached, the compressor automatically disengages, and the engine
RPM drops down to idle speed. The engine remains at idle until Air Tank pressure falls to a preset level.
The Gas Engine will then accelerate and air pressure once again begins to build up in the Air Tank.
Note:
As long as the engine is running, the operation of the Air Compressor
is automatic, controlled by an internal pressure switch.
IMPORTANT:
The internal pressure switch is not user adjustable;
do not make changes to the
air pressure settings of the internal pressure switch.
Any change to the automatic pressure
levels may cause excess pressure to accumulate, causing a hazardous situation.
Note: Depressurization -
If it is necessary to quickly
depressurize
the Compressor, turn OFF the engine.
Then, pull on the ring on the tank Safety Valve to release stored air pressure.
10. Use the air tool as needed.
11. After the job is complete, turn OFF the engine.
To stop the engine in an emergency,
turn the Engine Switch off.
Under normal conditions, use the following procedure:
a. Turn the Engine Switch off.
b. Close the Fuel Valve.
