ENGINE OIL
WARNING
Checking the level and changing the oil should be
done in solid and level ground. The engine has to be
stopped at all times. If the engine had been running,
it will be hot and the procedure should be done with
care in order to avoid burn danger.
To check the oil level:
1. Remove the oil filler cap.
2. Wipe the oil dipstick clean.
3. Insert the oil dipstick into the oil filler neck,
without screwing it.
4. Remove the oil dipstick and check the oil level
shown on it. If required, fill with oil to the upper
level.
5. Place the oil dipstick in position and tighten
appropriately.
Frequency
To change the oil:
NOTE
Drain the used oil while the engine is warm. Warm oil
drains quickly and completely.
WARNING
Take necessary protective measures against hot oil
to avoid any danger of burn.
1. Remove the oil filler cap from the engine oil
filler neck.
2. Place a suitable container (Fig. 10.3) under the
oil drain hole (Fig. 10.2) to catch the used oil.
3. Remove the oil drain plug (Fig. 10.4) and washer
(Fig. 10.5) to allow the oil to drain completely.
NOTE
Dispose used motor oil and the containers in a
manner that is compatible with the environment.
We suggest you take it in a sealed container to
your local recycling center or service station for
reclamation. Do not throw it in the trash, pour it
on the ground, or pour it down a drain.
4. Reposition the oil drain plug with its washer
and tighten appropriately.
5. Gradually add enough oil to bring the oil level
to the lip of the oil filler neck, up to the upper
level (Fig. 3.3) and not lower than the lower lev ­
el (Fig. 3.4).
6. Reposition the oil filler cap and tighten appro ­
priately.
WARNING
Running the engine will low oil level will cause en­
gine damage.
NOTE
If the engine frequently works under dusty or other
severe circumstances, change the engine oil every
10 hours.
AIR FILTER
WARNING
Operating the engine without an air cleaner, or with
a damaged air cleaner, will allow dirt to enter the en ­
gine, causing rapid engine wear.
To check, clean or change the air filter:
1. Remove the air filter cover (Fig. 11.1).
2. Make sure that the air filter element (Fig. 11.2)
is free from dirt and in a good condition. If it is
dirty, remove and clean it.
f
To clean a foam air filter element wash it with
home detergent and hot water and let it dry.
Then soak it in clean saturated engine oil and
gently squeeze out excess oil. If required, re ­
place it with a new one.
f
To clean a paper air filter element, clean light
dirt by gently taping it a few times on a hard
surface and replace if heavy dirt is present.
3. Clean the inside of the air filter case and cov ­
er from dirt with a soft cloth. If the engine is
equipped with an oil bath type air filter, replace
the oil with new engine oil.
4. Reinstall the air filter element and follow the
reverse procedure to put back in position the
air filter cover.
WARNING
Never clean the air filter with flammable or low
flash­point detergents to avoid the risk of a fire or
explosion.
