Installation and start-up
■
Only operate the tool at the motor speed re-
quired for the respective work. Avoid using
the maximum speed in order to reduce noise
and vibrations.
■
The noise and vibrations of the tool may in-
crease due to improper use and mainte-
nance. This leads to health damage. In this
case, immediately switch off the tool and
have it repaired by an authorised service
workshop.
■
The degree of stress due to vibration de-
pends on the work to be performed or on the
use of the tool. Estimate the stress and plan
appropriate work breaks. This considerably
reduces stress due to vibration over the en-
tire working time.
■
Extensive use of the tool exposes the opera-
tor to vibrations, which can lead to circulatory
issues ("white fingers"). To avoid this risk,
wear gloves and keep your hands warm. If
any symptoms of "white fingers" occur, im-
mediately consult a physician. These symp-
toms include: Numbness, loss of feeling, tin-
gling, itching, pain, reduced muscular
strength, changes in the colour or condition
of the skin. Normally these conditions affect
the fingers, hands or pulse. The risk increas-
es at low temperatures.
■
Take long breaks during your working day so
you can recover from the noise and the vibra-
tions. Plan your work in such a way that the
use of appliances that generate strong vibra-
tions is spread over several days.
■
If you notice an unpleasant sensation or disc-
olouration of the skin on your hands when us-
ing the tool, stop work immediately. Take suf-
ficient work breaks. Without sufficient breaks,
a hand/arm vibration syndrome can occur.
■
Minimise your risk of being exposed to vibra-
tions. Maintain the tool according to the in-
structions in the operating instructions.
■
If the tool is used frequently, contact your
dealer to purchase anti-vibration accessories
(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 appli-
ance is inevitable. Carry out noisy work at ap-
proved and specified time periods. Observe rest
periods as necessary and restrict the duration of
2500117_b
the work to a minimum. For your personal protec-
tion and protection of persons in the vicinity, ap-
propriate hearing protection 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. Be-
fore all work with the saw chain, heed
the following:
■
Switch off the appliance and remove
the rechargeable battery.
■
Wear protective footwear.
1. Loosen (02/a) the fastening nut (02/1) of the
chain sprocket cover (02/2). Remove the fas-
tening nut and chain sprocket cover.
2. Use the screwdriver on the combination
spanner to loosen 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 guide pin (05/4) grips in the slot-
ted 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
tighten (06/a) with the fastening nut (06/2).
