7.3 REFUELLING
Refuelling must take place when
the machine is switched off and
the spark plug cap removed.
Before refuelling:
1. Shake the fuel mixture container well.
2. Place the machine on a flat stable surface,
with the fuel tank cap facing upwards.
NOTE The following symbol is found
near the fuel tank cap (Fig.31.A):
Fuel mixture tank
3. Clean the fuel tank cap and the
surrounding area to prevent any dirt from
entering the tank during refuelling.
4. Open the fuel tank cap carefully to allow
the pressure inside to decrease gradually.
5. Use a funnel to refill and avoid
filling the tank to the brim.
NOTE When using the machine,
the fuel level can be checked through
the tank window (Fig. 31.B).
7.4 TOPPING UP THE CHAIN OIL TANK
NOTE The following symbol is found
near the chain oil tank cap (Fig. 31.C):
Chain oil tank
IMPORTANT Only use chain saw
oil or adhesive oil for chain saws. Do
not use oil containing impurities so as
not to block the oil filter and to prevent
irreparable damage to the oil pump.
It is essential that you use good quality oil
to lubricate the cutting parts effectively.
Used or poor quality oil does not
guarantee good lubrication and reduces
the working life of the chain and bar.
– It is always worth topping up the oil tank
completely (using a funnel) every time
you refuel. Since the oil tank capacity
is enough to guarantee that the fuel
runs out first, you will avoid the risk of
operating the machine without lubricant.
7.5 CLEANING THE MACHINE
AND THE ENGINE
After every work session, clean the machine
thoroughly to remove all dust and debris.
• To reduce fire hazards:
– keep the machine and, in particular, the
engine and the muffler zone free of sawdust,
branches, leaves, or excessive grease;
– use compressed air to clean the cylinder
fins on a regular basis (Fig. 32).
• To avoid overheating and
damage to the engine:
– always keep the cooling air vent (Fig. 33)
clean and free of sawdust and debris.
• Keep the clutch bell free of sawdust and
debris(Fig. 34), removing the clutch (par.
4.2) and remounting it correctly afterwards.
Have your dealer check the greasing of the
internal bearing about every 30 hours.
7.6 CLEANING THE CHAIN
Remove any traces of sawdust or oil deposits
from the chain every time it is used.
If there is excessive dirt or resin build-up,
disassemble the chain and place it in a
container with a specific cleanser for a few
hours. Then rinse it with clean water and
treat it with a suitable anticorrosive spray,
before reassembling on the machine.
7.7 CHAIN CATCHER
Before use, always check the condition
of the chain catcher (Fig.1.H) beforehand
and replace it if damaged.
7.8 NUTS AND BOLTS
• Before use, always check that all nuts and
bolts are securely tightened to be sure the
machine is in safe working condition.
• Before use, always check that the
handgrips are firmly fastened in place.
