Precautions for Removing Hot Oi! to Prevent Burns
If extracting oil from the engine while it is still hot, do not let the oil splash
on you.
During initial operation of the engine, the oil is quickly contaminated due to the initial wear of
internal parts. The lube oil must therefore be replaced early. Replace the lube oil filter at the same
time.
©Drain off the lube oil.
It is easier and more effective to drain the
engine lube oil while the engine is still warm
after operation.
1) After removing the oil dipstick, attach
the hose of the oil drain pump (optional) to
the dipstick guide.
2) Drain off the oil with the drain pump.
3) Remove the drain plug at the bottom of
the engine oil cooler and drain off the oil
inside.
