Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact the skin.
NOTICE
Per
form this maintenance with the engine stopped.
Note: After the engine has been switched OFF, wait
fo
r ten minutes in order to allow the engine oil to drain
to the oil pan before checking the oil level.
NOTICE
O
perating your engine when the oil level is above the

acteristics and could result in the loss of power.
