Installation and start-up

■
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 appliance, stop work
immediately. 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 appliance according
to the instructions in the oper-
ating instructions.
■
If the appliance is used fre-
quently, contact your dealer to
purchase anti-vibration ac-
cessories (e.g. handles).
■
Avoid working with the appli-
ance at temperatures below
10 °C. Define how the vibra-
tion load can be limited in a
work plan.

cinity, appropriate hearing pro-
tection must be worn.

the following:
■
Switch off the appliance
and remove the re-
chargeable battery.
■
Wear protective foot-
wear.

chain sprocket cover (02/2) with the screw-
driver on the Allen key (02/a). Remove the
fastening screw and chain sprocket cover.
