pulse. The risk increases at
low temperatures.
■
Take long breaks during your
working day so you can re-
cover from the noise and the
vibrations. Plan your work in
such a way that the use of ap-
pliances that generate strong
vibrations is spread over sev-
eral days.
■
If you notice an unpleasant
sensation or discolouration of
the skin on your hands when
using the tool, stop work im-
mediately. Take sufficient
work breaks. Without suffi-
cient breaks, a hand/arm vi-
bration syndrome can occur.
■
Minimise your risk of being
exposed to vibrations. Main-
tain the tool according to the
instructions in the operating
instructions.
■
If the tool is used frequently,
contact your dealer to pur-
chase anti-vibration accesso-
ries (e.g. handles).
■
Avoid working with the tool at
temperatures below 10 °C.
Define how the vibration load
can be limited in a work plan.

3.9.3 Noise pollution

A certain level of noise exposure
from this appliance is inevitable.
Carry out noisy work at ap-
30
proved and specified time peri-
ods. Observe rest periods as
necessary and restrict the dura-
tion of the work to a minimum.
For your personal protection and
protection of persons in the vi-
cinity, appropriate hearing pro-
tection must be worn.

4 INSTALLATION AND START-UP

4.1 Installing the guide rail and saw chain
(02 – 06)
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 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.
