in very serious injuries to the worker or persons
in the vicinity. The risk of kickback is particularly
great when performing cross cuts, angled cuts
and longitudinal cuts, as it is not possible to use
the claw stop on these cuts. You should therefore
avoid these cuts as far as possible and take
particular care when they are unavoidable.
The risk of kickback is at its greatest when the
saw is positioned for a cut in the region of the tip
of the cutter rail, as the leverage effect is greatest
there (Fig. 20). It is therefore safest to position the
saw flat and as close as possible to the claw stop
before making the cut (Fig. 21).
Caution:
•
Make sure that the chain tension is always
correctly adjusted.
•
Only use a chainsaw if it is in perfect working
order.
•
Only work with a saw chain that has been
properly sharpened in accordance with the
instructions.
•
Never operate the saw above shoulder height.
•
Never cut with the upper edge or the tip of the
sword.
•
Always hold the chainsaw firmly with both
hands.
•
Whenever possible, use the claw stop as a
leverage point.
Cutting wood which is under tension
Special care is required when cutting wood which
is under tension. Wood which is under tension
from which it is released by cutting may in
some cases react completely unpredictably and
uncontrollably. In the worst case this could result
in extremely severe or even fatal injuries (Fig. 22-
24). This type of work must only be performed by
persons who have been specially trained.

8. Maintenance
8.1 Replacing the saw chain and cutter rail
The cutter rail needs to be replaced if
•
the guide groove of the cutter rail is worn;
•
the nose sprocket in the cutter rail is damaged
or worn.
Proceed as described in the section “Assembly of
the cutter rail and the saw chain”.
8.2 Checking the automatic chain lubrication
You should check the operation of the automatic
chain lubrication system on a regular basis in
order to guard against overheating and the
associated damage to the cutter rail and the saw
chain. To do this, point the tip of the cutter rail
towards a smooth surface (board, section of a cut
tree) and allow the chainsaw to run.
If an increasing oil trace becomes evident during
this process then the automatic chain lubrication
system is working properly. If no clear oil trace is
evident then please refer to the corresponding
instructions in “Troubleshooting”. If the
information contained there still fails to remedy
the situation then please contact our service
department or another similarly qualified
workshop.
Caution:
Do not actually touch the surface with
the tip of the cutter rail when performing this
test. Keep a safe distance (approx. 20 cm).
8.3 Sharpening the saw chain
Effective working with the chainsaw is only
possible if the saw chain is in good condition and
sharp. This also reduces the risk of kickback.
