■
Do not secure the wood with your foot and do
not get another person to hold it.
8 MAINTENANCE AND CARE
WARNING! Danger of cuts and lacera-
tions. Danger of cuts and lacerations when
reaching into sharp-edged, moving appliance
parts and into cutting tools.
■
Before maintenance, care and cleaning work,
always switch off the appliance. Remove the
rechargeable battery.
■
Always wear protective gloves during mainte-
nance, care and cleaning work.
The chain saw complies with all relevant safety
standards. Repairs are only allowed to be per-
formed by qualified specialists, and with the ex-
clusive use of genuine spare parts.
■
After each use, check the chain saw for wear
and renew any damaged components.
■
Do not get the machine wet or expose it to
moisture. Clean plastic parts with a cloth and
do not use any cleaning agents or solvents.
■
Clean the cooling air slots if they are blocked.
■
Do not spray the chain saw not with water
and do not use a high-pressure cleaner.
■
Only use spare parts specified by the manu-
facturer.
8.1 Sharpening the saw chain (17)
DANGER! Danger of fatal injury due to
kickback! Improperly sharpened saw chain in-
creases the danger of kickback and thus the dan-
ger of fatal injury.
■
Sharpen the saw chain properly to reduce the
risk of kickback.
NOTE Inexperienced chain saw operators
are recommended to have the saw chain sharp-
ened by a specialist at the customer service.
The saw chain must always be well-sharpened
for reasons of safety and efficiency.
Sharpening is required if:
■
The saw chips are like sawdust.
■
Greater force is necessary for cutting.
■
The cut is not straight.
■
Vibration increases.

If you get trained customer service personnel to
sharpen the chain for you, they will be able to do
this with the appropriate tools for a minimum of
material removal and uniform sharpening of all
teeth.
You can sharpen the saw chain yourself using
special round files whose diameters are adapted
to the specific chain type (see chapter 8.5 "Chain
maintenance table", page 45). A certain amount
of skill and experience is necessary to avoid
damage to the teeth.
To sharpen the saw chain:
1. Switch off the chain saw and remove the re-
chargeable battery.
2. Release the chain brake.
3. Clamp the chain bar with fitted saw chain in a
suitable vice, taking care that the saw chain
can move freely.
4. Tension the chain if it is slack.
5. Place the file in the corresponding guide and
then guide the file through the opening of the
tooth making sure that you keep an even an-
gle according to the tooth profile.
6. Only perform a few strokes of the file and ex-
clusively in the forwards direction, then re-
peat the working step on all teeth in the same
orientation (right or left).
7. Reverse the position of the chain bar in the
vice and repeat the working step on the re-
maining teeth.
8. Check that the limit tooth does not project be-
yond the checking tool, and file off any pro-
jection using a flat file, then round down the
profile.
9. After sharpening, clean away all filings and
dust, then lubricate the saw chain in an oil
bath.
The chain must be replaced if:
■
The length of the teeth is less than 5 mm;
■
Where applicable: The mark on the teeth of
the cutting elements is exceeded;
■
The play on the links at the chain rivets is ex-
cessive.
8.2 Cleaning the chain sprocket interior
Thoroughly clean the chain saw after each use.
1. Remove the rechargeable battery and place
the chain saw on a stable base.
2. Unbolt the cover of the chain sprocket.
3. Clean the inside with a suitable brush.
