Cutting wood which is under tension
Special care is required when cutting wood which
is under tension. Cutting wood which is under
tension can release the tension, causing the
wood to react out of control. In the worst case
this can result in severe and even fatal injuries.
This type of work must be performed only by
specially trained persons.

9.1 Replacing the chain and cutter bar
The cutter bar needs to be replaced if the guide
groove of the cutter bar is worn.
Proceed as described in the section „Fitting the
cutter bar and the chain".
9.2 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
damage this can cause to the cutter bar and the
chain.
Point the tip of the cutter bar at a smooth surface
(a board or a cut tree face) and allow the
pole saw to run. If you see a growing oil stain
on the smooth surface, the automatic chain
lubrication system is working properly. If
there is no clear oil stain, please refer to the
corresponding instructions in the section
„Troubleshooting". If the information
contained there still fails to remedy the
situation, please contact our service department
Important! Do not actually touch the surface with
the tip of the cutter bar when performing this
test.
Keep a safe distance (approx. 8").
