Change Engine Oil and Replace
Engine Oil Filter Element
The engine oil on a new engine becomes
contaminated from the initial break-in of internal
parts. It is very important that the initial oil
replacement is performed as scheduled.
It is easiest and most effective to drain the engine
oil after operation while the engine is still warm.
WARNING! Burn Hazard. ALWAYS stay clear of
the hot engine oil to avoid being burned.
1. Turn engine off.
2. Remove engine cover.
3. NOTICE: NEVER use an adjustable wrench or
other open-end tool as there is a risk of
damaging the filter cover. Loosen the engine oil
filter cap (Figure 8-6, (2)) 1 - 2 turns with a
socket wrench.
