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. 24-26).
This type of work must only be performed by persons
who have been specially trained.

Danger!
The specified vibration value was established in
accordance with a standardized testing method. It
may change according to how the electric equipment
is used and may exceed the specified value in
exceptional circumstances.
The specified vibration value can be used to compare
the equipment with other electric power tools.
The specified vibration value can be used for initial
assessment of a harmful effect.
Keep the noise emissions and vibrations to a
minimum.
n Only use appliances which are in perfect working
order.
n Service and clean the appliance regularly.
n Adapt your working style to suit the appliance.
n Do not overload the appliance.
n Have the appliance serviced whenever
necessary.
n Switch the appliance off when it is not in use.
n Wear protective gloves.
8. Maintenance
8.1 Replacing the saw chain and cutter rail
The cutter rail needs to be replaced if
앬 the guide groove of the cutter rail is worn;
앬 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.
Danger! Do not actually touch the surface with the tip
of the cutter rail when performing this test. Keep a
safe distance (approx. 20 cm).
