8. OCCASIONAL MAINTENANCE
8.1 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.
8.2 MAINTENANCE
CHAIN
To ensure that the chainsaw works safely
and efficiently, it is essential that the cutting
means are well-sharpened.
Always wear heavy duty gloves when
handling the bar and chain.
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 an
Authorised centre sharpen the chain using the
right tools to ensure minimum removal of material
and even sharpness on all the cutting edges.
8.2.1 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.
8.3 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.
OF THE TOOTHED
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. 34.A);
3. clean the lubrication holes (Fig. 34.B);
4. with a flat file, remove burr from the edges and
level off the guides.
8.3.1 Replacing the bar
Replace the bar whenever:
– the groove is not as deep as the height of
the drive links (which must never touch the
bottom);
– the inside of the guide is worn enough to
make the chain lean to one side.
9. STORING
9.1 STORING THE MACHINE
When the machine is to be stored away:
1. Remove the battery from its housing and
recharge it;
2. Mount the bar cover.
3. Wait until the motor is sufficiently cold;
4. Clean (par. 7.4).
5. Check there are no loose or damaged
components. If
damaged components and tighten any screws
and loose bolts or contact the authorised
service centre.
6. Store the machine:
– in a dry place
– protected from inclement weather
– in a place where children cannot get to it
– making sure that keys or tools used for
maintenance are removed.
– at an ambient temperature between -20 to
85° C
7. the machine can be hung on the wall (Fig. 32.
I - II) .
NOTE Make sure that the wall can hold loads of
minimum 20 kg
9.2 STORING THE BATTERY
Charge the battery (par. 7.2.2)
The battery must be stored in closed and humidity-
free environments, at a temperature between:
EN - 15
necessary, replace the
