Changing the Engine Oil
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 arailable to drain the
engine oil after operation while the engine
is still warm.
WARNING
Burn Hazard.
If you must drain the engine oil while it
is still hot, stay clear of the hot engine
oil to avoid being burned. Always wear
eye protection.
1. Turn the engine off.
2. Remove the engine oil dipstick. Attach
the oil drain pump (if equipped) and
pump out the oil.
For easier draining, remove the engine
oil fill cap. Dispose of used oil properly.
NOTICE
•Prevent dirt and debris from
contaminating engine oil. Carefully
clean the dipstick and the surrounding
area before removing the dipstick.
•Always be environmentally
responsible.
3. Fill with new engine oil. See Adding
Engine Oil on page 32.
NOTICE
Never mix different types of engine oil.
This may adversely affect the lubricating
properties of the engine oil.
Never overfill.
Overfilling may result in white smoke,
engine overspeed or internal damage.
4. Perform a trial run and check for oil leaks.
5. Approximately 10 minutes after
stopping the engine, remove the oil
dipstick and check the oil level. Add oil
if the level is too low.
