CAUTION
Always wear personal protective
equipment such as gloves, safety shoes
or boots, eye, and hearing protection as
required for the task at hand.
CAUTION
Compressors and motors generate heat
and create hot surfaces. Use caution
when operating or servicing equipment.
Some surfaces and components may be
hot.
NOTE
Inspect and replace damaged
components before operation with
Genuine Vanair Replacement Parts.
Using replacement parts other than
Genuine Vanair Replacement Parts will
void the warranty.
NOTE
It may be necessary to change the
compressor oil and oil filter at earlier
intervals if the compressor oil has water
contamination or if the compressor
system is operated in a dirty
environment.
NOTE
Do not mix different compressor fluid
types. Use Vanguard compressor oil.
NOTE
Refer to the Truck Operator’s Manual for
detailed maintenance and replacement
procedures for the motor.
