is designed to run continuously to assure a
constant flow of cooling air.
The operator should be aware that high
temperatures can influence engine
performance, which can directly effect some
machine function capacity outputs.
TABLE 6.3C HIGH TEMPERATURE OPERATION
Symptom
Cause
Prevention / Corrective Action
Overheating/high
compartment temperatures
Diminished engine
performance
High ambient temperatures, con-
fined spaces, soundproof cases
and other reasons. Among these
the most important factor is the
temperature of the intake and
cooling air.
• Extra care should be taken to keep the engine and
air compressor clean and to not restrict the air flow
around the unit.
• Consult the Engine Operator’s Manual for fuel,
lubrication oil and cooling requirements under
extreme temperatures.
• At the minimum, all coolers, including air passage
ways around the coolers, should be free of debris
and dirt. The fan, driven by the engine, is designed
to run continuously to assure a constant flow of
cooling air.
The operator should be aware that high temperatures
can influence engine performance, which can directly
effect some machine function capacity outputs.
6.3.4 HIGH DUST CONTENT OPERATION
Consult the information in
Table 6.3D
for
preventative and/or repair measures. When
the machine is to be used in continuously
dusty environments, special care must be
taken with the engine’s air cleaner and
radiator.

Symptom
Cause
Prevention / Corrective Action
Overheating
System contamination
Stalling
Machine components exposed to
frequent or constant dust interac-
tion, can result in diminished sys-
tem performance, or machine
cessation.
• The intake air must be cleaned with the air
cleaner—inspect the air filter frequently for dust
build-up and replace as needed.
• Ensure that the radiator and oil cooler fins are
kept clean to prevent overheating.
• If the machine is not being used for an extended
period of time, an additional precaution, such as
covering the machine with a tarp, will help to keep
the inside of the machine free of dust particle
accumulation.
• For extreme cases of high dust content environ-
ments, machine fluids may need to be replaced at
more frequent intervals. Adjust maintenance
schedule accordingly.
