NG/LP FUEL CONVERSION
This generator set was tested on both LP and NG at the
factory. Ensure proper fuel configuration before operating.
CAUTION: EQUIPMENT DAMAGE
Do not make any fuel adjustments or governor
adjustments until all pressure readings are in
compliance with specification.
These engine/generator sets are easy to convert between LP
or NG. As the engine timing is controlled by the ECU on the
engine you only need to tell it what fuel you want to operate
on. A small rocker switch has been provide on the underside
of the engine control cabinet for this purpose.
Opening the rocker switch will tell the ECU mounted on the
engine that you are operating on NG Fuel. Closing the rocker
switch will tell the ECU that the fuel being supplied is LP. The
Advance Power Controller has an indicator light for LP. When
this light is on, the engine is set-up for LP, when the LP light is
out the engine is set up for NG. The ECU will then reprogram
the engine to operate on the proper fuel.
LUBRICATION & COOLANT
Before starting the engine, check the oil level in the crankcase.
If it is low, refill to the full mark with the proper weight/
grade of oil as recommended by the engine manufacturer’s
maintenance instructions. The necessity of using the correct
oil and keeping the crankcase full cannot be over emphasized.
Failure to do so will cause excessive engine wear and shorten
its useful life.
Winco recommends our 5W-30 fully synthetic heavy duty
engine oil to give you maximum cold weather protection
while maintaining excellent performance in warmer
weather. We have partnered with a national lubrication oil
manufacturer to give you access to Winco private branded
premium oil available at comparable prices to conventional
oils. See your dealer for additional information.
Before starting the engine, Check the coolant level in
the radiator. If it is low, refill as specified in the engine
manufacturer’s maintenance instructions. The radiator should
be filled to about 1 inch below the filler neck.
