4.7.1.1 ENGINE OPERATION
The standard recommendation of 10W-30
engine oil is suitable for temperatures down
to -5°F. If temperatures are consistently
below 30°F, it is recommended that 5W-30
oil be used. If temperatures are below -25°F,
a high-performance, fully synthetic oil, such
as AMSOIL 5W-30 should be used, which is
suitable to temperatures of -55°F.
In below zero temperatures, a fuel line deicer
product may need to be used.
Drain the moisture from the tank when it is
warm from extended operation.
4.7.2 HIGH TEMPERATURE OPERATION
The standard recommendation of 10W-30
engine oil is suitable for operation in
temperatures up to 110°F.
Extra care should be taken to keep the
engine and air compressor clean and to not
restrict the air flow around the unit.
4.7.3 HIGH ALTITUDE OPERATION
Engine horsepower will decrease by 3.5%
for every 1,000 ft. increase in altitude. At
high altitude overall unit performance will
deteriorate, and care will need to be taken
not to overload the engine by using more
than one function of the unit.
NOTE
Ethanol blended fuels, such as E85, are
prohibited for use with the Kohler CH440
engine. DO NOT use ethanol-based fuels.
Consult
Section 2
of this manual, and the
Engine Owner’s Manual for acceptable
fuel specifications.
NOTE
For additional information on engine
operation, consult the Engine Owner's
Manual.
