For maximum performance and longevity, the engine oil
should be replaced after the first 8 hours of operation.
After the initial oil change, it should be changed every 125
hours of operation or semi-annually, whichever comes
first.
The selection of oil is dependent upon the service that the
vehicle will perform. Most vehicles require 10W-30 oil,
whereas vehicles used at capacity or near capacity load
applications will utilize 10W-40 oil after a break-in period
of 100 hours (Ref. Fig. 3).

NOTICE: If vehicle is to be stored over the winter
months, it can be stored with the old oil left in
engine. The oil should be changed as part of spring
maintenance to remove any moisture that has accu-
mulated during storage.
Engine fluids can be hot and con-
tact with the skin can cause severe
burns. Wear rubber gloves to pro-
tect skin from exposure to the old oil and degreaser.
The oil should be changed with engine warm. Park the
vehicle on a level surface, engage parking brake and
remove the key from the vehicle (Ref. Fig. 4).

ent. This is normal and is a result of the engine break-in
process. Inspect the filter at every oil change. The pres-
ence of large metal chips can indicate possible damage to
