internal parts. It is very important that the
initial oil change is performed as
scheduled.
It is easiest and most effective to drain the
engine oil after operation while the engine
is still warm.

CAUTION
• Only use the engine oil
specified. Other engine oils
may affect warranty coverage,
cause internal engine

shorten engine life.
• Prevent dirt and debris from
contaminating engine oil.
Carefully clean the oil
cap / dipstick and the
surrounding area before you
remove the cap.
• NEVER mix different types of

affect the lubricating
properties of the engine oil.

result in white exhaust smoke,
engine overspeed or internal
damage.
