Chain Catcher; Machine And Bar Lubrication Holes; Nuts And Bolts; Occasional Maintenance - Alpina CS 40 Li Manuel D'utilisation

• 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 the chain stop pin conditions before each
use (Fig. 1.H) and repair in the event of damages.
7.6 MACHINE AND BAR
LUBRICATION HOLES
Before daily use, remove the guard (par.
4.2), disassemble the bar and check that
machine lubrication holes (Fig. 26.A) and
guide bar (Fig. 26.B) are not clogged.

7.7 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. 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 OF THE
TOOTHED CHAIN
To ensure that the chainsaw works
safely and efficiently, it is essential that
the cutting means are 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 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.
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.
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.
