the minimum, all coolers, including air passage ways
around the coolers, should be free of debris and dirt.
The operator should be aware that high temperatures
can influence motor performance, which can directly
effect some machine function capacity outputs.
5.8.3 HIGH DUST CONTENT OPERATION
5.8.3.1 MACHINE OPERATION
When the machine is to be used in continuously dusty
environments, special care must be taken with the
compressor air filter and cooler assembly, as well as the
hydraulic fan cooler. This can be accomplished by
performing more frequent monitoring of the air filter and
coolers when operating in areas that contain a high dust
content.
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.
5.8.4 HIGH ALTITUDE OPERATION
Motor 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 motor by using more than one
function of the unit at a time.
NOTE
If operating the machine in high
humidity, the drain valve can be left
partially open to relieve water build-up
during operation. This water may contain
a small amount of oil.
Consult
Section A.5
, for order number.
NOTE
The effect of humidity should be taken
into consideration when operating in
areas with high temperatures.
