LUBRICATION AND SERVICE
WARNING
These vehicles are equipped with engine and
transmission oil pans which permit operation at
maximum gradeability as designated in the
'Performance Data' section of the relevant Sales
Specification Sheet.
Lubrication is an essential part of preventive
maintenance. It is important that the instructions
regarding lubricant specifications, and the frequency of
their application, be followed to prolong the useful life
of the vehicle. Periodic lubrication of moving parts
reduces to a minimum the possibility of mechanical
failures.
All change periods are recommendations based on average
operating conditions. Lubricants showing evidence of
excessive heat, oxidation or dirt should be changed more
frequently to prevent these conditions.
Lubricant change and service periods must be
established on the basis of individual job conditions
utilizing oil sampling and recommendations from
lubricant suppliers.
Thoroughly clean all fittings, caps, plugs etc., to
prevent dirt from entering any system while carrying
out servicing procedures. Lubricants must be at normal
operating temperature when draining.
Note: Do not operate any system unless oil level is
within the recommended operating levels as indicated
on oil level dipstick, sight gauge or level plug.
Small circles on the following illustration represent
points at which lubrication and/or servicing must take
place, at the intervals indicated on the left hand side of
the lubrication and service chart.
The numbered circles on the illustration contain
reference numbers which correspond to the reference
numbers in the 'Ref. Points' column of the lubrication
and service chart.

cause burns to unprotected skin.
Always deflate the tyre before trying to remove any
embedded objects or removing the tyre and rim
assembly from the vehicle.
