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. 9 IMpORTANT: Allow the engine to run for five minutes with no load after each start-up so that the engine can stabilize. 10. Adjust the Throttle as needed. 11. Break-in period: a. Breaking-in the engine will help to ensure proper equipment and engine operation. b. The operational break-in period will last about 3 hours of use. During this period: SETUp • Do not apply a heavy load to the equipment. • Do not operate the engine at its maximum speed. c. 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. OpERATION 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. 12.
