S 07 MAINTENANCE
CHECKING THE ENGINE OIL LEVEL
DANGER!
Stop the engine before checking the oil level.
Engine oil level
• To check the oil level, take out the dipstick (red cir-
cle), wipe it clean, put it back in and take it out again.
Check that the oil level is between the two notches
(Mini - Maxi).
• If the level is too low, add new oil to the specified level.
IMPORTANT!
When using a different brand or viscosity of oil, change
the old oil. Never mix two different types of oil.
NOTE!
Be sure to inspect the engine by placing it on a level sur-
face. If it is placed on slopes, the oil level may not be
measured accurately.
Be sure to keep the oil level between the upper and lower
limits of the dipstick. Too much oil can cause poor per-
formance or excessive leakage gas. On closed breather
engines where mist is drawn through the port, too much
oil can cause water hammer. Lack of oil can cause seizure
of rotating and sliding parts of the engine.
CHECKING THE ENGINE COOLANT LEVEL
• Remove the expansion tank cap (1) and check that
the coolant level is between the low and high marks.
• If the coolant level is too low, check the reason for the
low coolant level.
IMPORTANT!
If the coolant decreases due to evaporation, refill only
with fresh water. If the coolant is leaking, refill with the
same brand and type of coolant in the specified mixing
ratio (50% fresh water and 50% antifreeze). If the brand of
coolant cannot be identified, or if it is different from the
previous brand, drain all remaining coolant and refill with
a completely different brand of coolant mixture.
DANGER!
Do not remove the heat exchanger cap until the coolant
temperature is below boiling. Then loosen the cap slightly
to relieve any excess pressure before removing it com-
pletely.
IMPORTANT!
When filling the coolant, air must be removed from the
engine coolant passages. Be sure to close the heat ex-
changer cap tightly. If the cap is loose or improperly
closed, coolant can escape and the engine can overheat.
Do not use antifreeze and scale inhibitor at the same time.
Never mix different types or brands of antifreeze.
