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 (Figure 3).

If vehicle is to be stored over winter months, it can be
stored with old oil left in engine. The oil should be
changed as part of spring maintenance to remove any
moisture that has accumulated during storage.
Engine fluids can be hot and contact with the
skin can cause severe burns. Wear rubber
gloves to protect skin from exposure to the old
oil and degreaser.
The oil should be changed with engine warm. Park vehi-
cle on a level surface, engage parking brake and remove
key (Figure 4).
Figure 4 Cleaning Top of Engine
Be careful of hot oil when drained. It may be
hot enough to burn you severely.
Wipe the top of the engine clean with a cloth. Remove the
oil fill cap.
Place the oil drain pan under the oil drain plug (1) (Figure
5) found at the rear of the engine base. Remove the drain
plug (1). Allow the oil to drain into the drain pan.
Figure 5 Oil Drain Plug
Before installing the drain plug (1), clean the area around
the drain plug mount with a lint free cloth. Inspect the
drain plug (1) for damage; replace if necessary (Figure 5).
If the O-ring (2) on the drain plug is damaged, replace it
with a new one. Tighten the drain plug (1) to the torque
value specified below.
At the first oil change, small metal particles can be pres-
ent. This is normal and a result of the engine break-in
period. Inspect the filter at every oil change. The pres-
ence of large metal chips can indicate possible damage to
the engine.
