Danger!
– Waste engine oil may cause skin
cancer if it comes into contact
with the skin frequently and for a
prolonged period. Even though
this is unlikely, provided waste oil
is not handled daily, it is
advisable to wash hands as soon
as possible with soap and water
after working with waste oil.
– Drain the oil while the engine is
still warm but no longer hot (the
oil drains quickly and com
pletely).
– If the unit has to be tilted to drain
the oil, first run the engine until
the fuel tank is empty.
