Stopping the Gas Drive
The Gas Drive engine may experience a backfire if it is
shut off while the engine speed is above idle and the
compressor is building air pressure. This is normal and is
caused by the load on the engine during shut down.
The Exhaust system is equipped with a spark arrester.
To properly shut off the Gas Drive:
1) Close the air discharge valve or stop use of the air tool.
2) Allow the system to build to full air pressure (factory setting 150 psi)
so that the intake valve in the compressor inlet valve closes. At this
point the engine will idle down.
3) Allow the engine to run at low idle for 30 seconds.
4) Turn the key to the
“OFF” position to fully power-off all electronics.
Improper shut down may cause compressor oil to come
out of the compressor air filter.
Ensure the fuel switch is in the “CLOSE” position when the
unit is not being run or before moving to a different site.
Failure to do this may allow fuel to overfill the carburetor
float bowl and flow into the engine’s crank case and/or
cylinder causing the engine to hydraulically lock.
