Caution
If the engine oil pressure is too low, the
low oil pressure warning light will
illuminate. If this light stays on when
the engine is running, stop the engine
immediately and investigate the cause.
Running the engine with low oil
pressure will cause engine damage.
• Turn the ignition OFF, check the oil
level using the method previously
described, and top up to between
the minimum and maximum level
lines in the sight glass.
Disposal of Used Engine Oil and Oil

place used oil filters in with general
waste. If in doubt, contact your local
authority.

Do not add any chemical additives to
the engine oil. The engine oil also
lubricates the clutch and any additives
could cause the clutch to slip.
Do not use mineral, vegetable, non-
detergent oil, castor based oils or any oil
not conforming
specification. The use of these oils may
cause instant, severe engine damage.
Make sure that no foreign matter enters
the crankcase during an engine oil
change or top up.
