Read all of SAFETY and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.
Owner’s Guide
For maximum performance and longevity, the engine oil should
be replaced after the first eight 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.
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.
Be aware that engine fluids may be hot and contact to the skin may 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 vehicle on a level surface, engage parking brake and remove key.
Place a drain pan under engine. Wipe top of the engine clean with a cloth.
Remove the oil fill cap.
Be careful of hot oil when drained. It may be hot
enough to burn you severely
Place the oil drain pan under the oil drain plug (1) found at the
rear of the engine base.
Remove the drain plug (1) and allow the oil to drain into the
pan. At the first oil change,
small
metal chips and lint may be
found. This is normal, resulting from the break-in period.
Inspect the filter at every oil change. The presence of large
metal chips could indicate possible damage to the engine.
Before installing the drain plug, clean the area around the
drain hole with a lint free cloth and inspect the drain plug (1)
for damage; replace if necessary. If the O-ring (2) on the drain
plug is damaged replace it with a new one. Tighten the drain
plug to 62 in. lbs (7 Nm) torque.
