Engine Oil - Malaguti MALBO Line Service Manual

ENGINE OIL

Check oil level EVERY 500 KM (310 MILES)
As far as four-stroke engines are concerned, engine oil is
used to lubricate distribution components, base bearings
and the thermal unit. An insufficient oil quantity or use
a poor quality oil can seriously damage the engine.
In all four-stroke engines, deterioration of the oil and a
certain consumption are to be considered normal. Con-
sumption, in particular, strictly relates to conditions of us-
age (oil consumption increases if the vehicle is used with
the throttle fully open).
To prevent trouble, check the oil level more frequent-
ly with respect to the indications given in the MAIN-
TENANCE TABLE, especially before long journeys.
Checking the oil level
This check should be performed when the engine is cold,
as described below:
1 - Park the vehicle on flat ground and put it on its cen-
tre stand.
2 - Stop the engine and wait a few minutes for the oil to
stabilise.
3 - Unscrew the cap/dipstick (A-Fig. 20), dry it with a
clean cloth and refit it, without wrenching it.
4 - Remove the cap/dipstick and make sure the level
falls between the MAX and MIN notches; if neces-
sary, top up with Q8 CLASS 10W40 oil.
5 - Refit the cap/dipstick (A-Fig. 20).
When checking the oil level, make sure the ve-
hicle is upright; slight tilting may alter the read-
ings.
If you need to check the level when the engine
is warm, remember that the level line will be
lower. It is best to wait at least 10 minutes from
stopping the engine in order to have a correct
reading

Topping up
Before topping up, check the oil level and in no case
allow the level to rise above the MAX notch.
Never allow the level to rise above the MAX
mark! Excessive internal pressure can impair
performance and cause malfunctioning or
damage to the engine.
Change engine oil and clean the filtering net every
2,500 km/1,560 miles or 6 months
1 - Warm the engine up for a few minutes.
2 - Stop the engine and put an oil container under the
engine.
3 - Remove the drainage plug of the filtering net (A-
Fig. 21-22) and the dipstick, then let oil flow out.

4 - Clean the filtering net (C-Fig. 22) with a suitable
solvent and blow dry with compressed air.
5 - Refit the filtering net, a new O-ring (B-Fig. 22) and
the drain cap.
Make sure the O-ring is correctly seated.
6 - Tighten the drain cap at the requested torque set-
ting: Tightening torque: 25-28 Nm/2.5-2.8 kgm
7 - Fill the engine with 800 cc of Q8 CLASS 10W40 oil
and top up if necessary. Refit the dipstick.
8 - Run the engine and let it warm up; check for any
leaks. If leaks are noted, stop the engine and locate
their cause.
Letting the engine run with an insufficient
amount of lubricant or with the wrong types of
lubricant causes wear to moving parts and can
in the long run cause serious damage.
