ENGINE OIL
WARNING
Checking the level and changing the oil should be
done on 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 and necessary precautions in order to avoid burn
danger.
NOTE
Drain the used oil while the engine is warm. Warm oil
drains quickly and completely.
To check the oil level:
1. Remove the oil filler cap (Fig. 10.6) from the en -
gine oil filler neck (Fig. 10.1).
2. Check the oil level. The oil level should reach the
lip (Fig. 10.7) of the oil filler neck. If required, add
enough oil to bring the oil level to the lip of the
oil filler neck, up to the upper level and not lower
than the lower level.
3. Reposition the oil filler cap and tighten appro -
priately.
To change the oil:
1. Remove the oil filler cap from the engine oil filler
neck.

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.
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
and not lower than the lower level.
6. Reposition the oil filler cap and tighten appro -
priately.
NOTE
If the engine frequently works under extremely dusty
or other severe circumstances, change the engine oil
every 25 hours.
WARNING
Running the engine will low oil level will cause engine
damage.
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.
3. 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, replace
it with a new one.
4. 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.
5. 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.
6. 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 flash-
point detergents to avoid the risk of a fire or explosion.
NOTE
If the engine frequently works under dusty or oth -
er severe circumstances, clean the air filter every 10

SPARK PLUG
To maintain the spark plug (Fig. 12.4):
1. Remove the spark plug cap (Fig. 12.1) to access
the spark plug (Fig. 12.2).
2. Use an appropriate spark plug tool (Fig. 12.3) to
carefully remove the spark plug.
3. Inspect the condition of the spark plug and its
electrode. It must be clean and not worn. Check
that the spark plug gap is between 0.7 and
0.8mm. Replace the spark plug with a new one,
if needed.
4. Carefully thread the spark plug into the engine
by hand.
5. Once threaded, use the appropriate spark plug
tool to tighten the spark plug, paying attention
not to use excessive force damaging the threads.
6. Re-attach the spark plug cap.
WARNING
Never allow dirt or debris to enter the cylinder bore.
Before removing the spark plug, thoroughly clean the
spark plug and cylinder head area.
FUEL FILTER
The fuel tank may be fitted with a filter (Fig. 13),
depending on tiller model, situated at the fuel tank
cap. The fuel filter can be picked out and should be
checked periodically. If the filter is dirty, clean it and
replace it with a new one when required. In case the
inside of the fuel tank is dirty, it can be cleaned by
rinsing the fuel tank with clean petrol.
CLEANING
Use a small soft brush to clean the outside of the
unit. Do not use strong detergents. Household
cleaners that contain aromatic oils such as pine and
lemon and solvents such as kerosene can damage
plastic housing or handle. Wipe off any moisture
with a soft cloth.
