6.3 EXTREME CONDITION
OPERATION
When operating in extreme hot or cold
conditions, extra attention should be given to
any indications that could lead to a serious
problem. Machine review and maintenance
check schedules should be more frequent
than the normal suggestions given in
Section 5.3, Maintenance Schedule Table
.
Become familiar with the alternative
operation procedures given in this section
before operating the power system package
in any type of extreme ambient conditions.
6.3.1 COLD WEATHER OPERATION
Additional care should be taken under
consideration when operating the package in
extreme cold weather environments or
ambient temperatures.
Run machine with no load at full speed using
the generator switch to warm up the machine
(Refer to
Section 4,
Figure 4-2
[
A2
]).
6.3.1.1 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.
Check the fuel filter regularly to insure that it
contains no water.
Drain the moisture from the tank when it is
warm from extended operation.
NOTE
Ethanol blended fuels, such as E85, are
prohibited for use with the Kohler
engine. DO NOT use ethanol-based fuels.
Consult
Section 2, Specifications
of this
manual and the Engine Owner’s Manual
for acceptable fuel specifications.
