• Always clean the machine after use with a
damp cloth dipped in neutral detergent.
• Remove all traces of humidity using
a soft damp cloth. Humidity can
generate risks of electric shocks.
• Do not use aggressive detergents or solvents
to clean the plastic parts or handgrips.
• Do not spray water onto the motor
and electrical components and
prevent them from getting wet.
• To avoid overheating and damage to the
motor or the battery, always keep the
cooling air vents clean and free of debris.
7.4.2 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.
7.5 CHAIN CATCHER
Check chain stop pin conditions
before each use (Fig. 1.H) and repair
in the event of damages.
7.6
NUTS AND BOLTS
• Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
• Check regularly that the
handles are fixed firmly.
8. EXTRAORDINARY MAINTENANCE
8.1 MACHINE AND BAR
LUBRICATION HOLES
Periodically remove the chain guard
(par. 4.2), remove the bar and check that
machine lubrication holes (Fig. 26.A) and
guide bar (Fig. 26.B) are not clogged.
8.2 CHAIN DRIVE SPROCKET
Regularly check the condition of the sprocket
with your local dealer and replace it when
wear exceeds the accepted limits.
Do not mount a new chain with
a worn sprocket or vice-versa.
8.3 MAINTENANCE OF THE
TOOTHED CHAIN
To ensure that the chain saw works
safely and efficiently, it is essential
that the chain is well-sharpened.
Chain sharpening is necessary when:
– The sawdust looks like dust.
– Cutting becomes more difficult.
– The cut is not straight.
– Vibrations increase.
Kickback may occur if the chain
is not sufficiently sharpened
IMPORTANT It is recommended to have a
specialised centre sharpen the chain using the
right tools to ensure minimum removal of material
and even sharpness on all the cutting edges.
8.3.1 Replacing the toothed chain
Replace the chain whenever:
– the length of the cutting edges
reduces to 5 mm or less;
– there is too much play between
the links and the rivets.
– the cutting speed is too slow and the
repeated sharpening does not improve
the cutting speed. The chain is worn.
IMPORTANT After replacing the chain,
its tension level must be checked more
frequently due to settling of the chain.
8.4 GUIDE BAR MAINTENANCE
NOTE Any work on the guide bar requires
specific experience and special tools in order
to achieve top workmanship standards; for
safety purposes, we recommend you contact
your dealer to ensure work is done correctly.
To avoid asymmetrical wear on the bar,
make sure it is turned over periodically.
To keep the bar in perfect working
order, proceed as follows:
1. grease the bearings on the nose sprocket
(if present) with the syringe (not included).
2. clean the bar groove with the scraper
(not included) (Fig. 27.A);
3. clean the lubrication holes (Fig. 27.B);
4. with a flat file, remove burr from the
edges and level off the guides.
