Causes and operator prevention of kickback
Kickback may occur when the nose or tip of the
guide bar touches an object, or when the wood
closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a sudden
reverse reaction, kicking the guide bar up and
back towards the operator.
Pinching the saw chain along the top of the guide
bar may push the guide bar rapidly back towards
the operator.
Either of these reactions may cause you to lose
control of the saw which could result in serious
personal injury. Do not rely exclusively upon the
safety devices built into your saw.
As a chain saw user, you should take several
steps to keep your cutting jobs free from accident
or injury.
Kickback is the result of chain saw misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
■
Maintain a firm grip, with thumbs and fin-
gers encircling the chain saw handles,
with both hands on the saw and position
your body and arm to allow you to resist
kickback forces. Kickback forces can be
controlled by the operator, if proper precau-
tions are taken. Do not let go of the chain
saw.
■
Do not overreach and do not cut above
shoulder height. This helps prevent unin-
tended tip contact and enables better control
of the chain saw in unexpected situations.
■
Only use replacement guide bars and saw
chains specified by the manufacturer. In-
correct replacement guide bars and saw
chains may cause chain breakage and/or
kickback.
■
Follow the manufacturer's sharpening and
maintenance instructions for the saw
chain. Decreasing the depth gauge height
can lead to increased kickback.

General safety warnings for chain saws

Follow all instructions when clearing jammed
material, storing or servicing the chain saw.
Make sure the switch is off and the battery
pack is removed. Unexpected actuation of the
chain saw while clearing jammed material or ser-
vicing may result in serious personal injury.

4 INSTALLATION AND START-UP

4.1 Installing the guide rail and saw chain
(02 – 06)
CAUTION! Risk of injury from the saw
chain. The cutting edges of the saw chain are
very sharp so that there is a risk of cutting injuries
when handling the saw chain. Before starting any
work on the saw chain:
■
Switch off the appliance and remove the re-
chargeable battery.
■
Wear protective footwear.
1. Loosen the fastening screw (02/1) of the
chain sprocket cover (02/2) with the screw-
driver on the Allen key (02/a). Remove the
fastening screw and chain sprocket cover.
2. Use the screwdriver on the Allen key to loos-
en the chain tensioning screw (03/1). Turn
the chain tensioning screw until the chain
tensioning pin (03/2) is at the rear thread end
(03/a).
3. Insert the saw chain:
■
Align (04/a) the cutting teeth (04/1) of the
saw chain (04/2) that are to lie at the top
of the guide rail to the tip of the guide rail
(04/3).
Note: Make sure that the chain is cor-
rectly mounted!
■
Place the saw chain (04/2) in the groove
(04/4) of the guide rail and guide com-
pletely around the guide rail.
4. Lay the guide rail together with the saw chain
laid on it in the open housing:
■
Lay the saw chain (05/1) around the drive
sprocket (05/2).
■
Align the guide rail (05/3) in such a way
that the two guide pins (05/4) grip in the
slotted hole (05/5) of the guide rail.
■
Align the guide rail (05/3) so that the
chain tensioning pin (05/6) grips in one of
the two chain tensioning holes (05/7).
■
Align the saw chain (05/1) so that it is in
contact in the groove of the guide rail
(05/3) and on the drive sprocket (05/2).
5. Put on the chain sprocket cover (06/1) and
insert the fastening screw (06/2) and tighten
with the Allen key (06/a).
6. Tension the saw chain (see chapter 4.2 "Ten-
sioning and slackening the saw chain (07)",
page 29).
