V. General Maintenance Procedures
A.
Fuel System
The fuel system works from vacuum created by the engine running. Turning the safety fill cylinder valve on
pressurizes the system for flow to the carburetor once the engine starts to crank.

Note:
The regulator and carburetor, on this machine has been factory pre-set. Only Kent authorized
personnel
trained
and
certified

or adjust the system or its settings.
N.F.P.A. 58 8-1.4 states,
"In the interest of safety, each person engaged in installing,
repairing, filling, or otherwise servicing an LP-Gas engine fuel system shall be properly
trained in the necessary procedures."

Engine Dust Filter
The engine dust filter should be cleaned each hour and after each use by rinsing with mild
detergent.
Squeeze out excess water (do not wring). Allow the filter to air dry.
Failure to maintain a clean engine air filter will cause the engine to overheat. Also, it may
cause the exhaust emissions to elevate to harmful levels!
