7.3 Tensioning and slackening the saw
chain (14)
1. Tension the saw chain using the Phillips
head on the angle screwdriver (14/1):
■
Tensioning the saw chain: Turn chain
tensioning screw (14/2) in clockwise di-
rection (14/a).
■
Slackening the saw chain: Turn the chain
tensioning screw in anti-clockwise direc-
tion (14/b).
2. Check the chain tension (see chapter 7.2
"Checking the saw chain tension", page 38 ).
Repeat the previous step, if necessary.
7.4 Installing saw chain and chain bar (15 –
19)
If the cutting performance decreases, the saw
chain and possibly the chain bar must be re-
placed. The chain bar must be replaced if there
are clear signs of wear on the guide groove for
the saw chain.
Use only OEM spare parts for the saw chain and
guide rail (see
chapter 12 "Technical data",
page 43 ).
CAUTION! Risk of injury on the saw
chain. The cutting edges of the saw chain are
very sharp so that cutting injuries can occur when
handling the saw chain. Before all work with the
saw chain, heed the following:
■
Switch off the appliance and remove the re-
chargeable battery.
■
Wear protective gloves.

2. Open the fastening ring (15/1) for the sprock-
et cover (15/2).
3. Turn the fastening ring anti-clockwise.
4. Remove the sprocket cover (15/a).

■
Align the chain bar (18/3) in such a way
that the guide pin (18/4) engages in the
slotted hole of the chain bar.
■
Align the chain bar so that chain tension-
ing pin (18/5) engages in the chain ten-
sioning hole.
■
Align the saw chain so that it is in the
groove of the chain bar and on the drive
sprocket.

Put the sprocket cover (19/1) in position
(19/a).
■
Turn the fastening ring (19/2) clock-wise.
