◼ Stop the chainsaw immediately if the saw
chain becomes jammed on the guide rail.
– Do not pull the chainsaw out of the cut
with force. Force open the cut with a
wedge or bar.
◼ Before commencing work, always check
that the chain brake functions correctly.
− Allow the chainsaw to run at full speed
1 to 2 seconds for this purpose.
− Then push the front hand guard for-
wards by hand (chain brake lever).
− At maximum speed, the saw chain
must come immediately to rest.
◼ Before commencing work, always check
that the saw chain is in good order. The
saw chain must always be clean and
sharp. Only in this way can a high level of
safety against kickback be assured.
Felling a tree
◼ Before commencing work, determine the
direction in which the tree is to be felled.
Take account of:
− the wind direction
− the angle of the tree
− the position of the thickest branches
− any problems with subsequent measures
− other factors where necessary.
◼ Clear the work area around the tree. Mark
the exit route and ensure firm footing.
◼ Make a notch of approx. 1/3 of the tree's
diameter on the side that the tree should
fall.
◼ On the opposite side of the tree, make a
dropping cut. This must be slightly higher
than the notch.
Cutting to length, removing branches
◼ Ensure firm footing.
◼ Never stand on the trunk.
◼ Ensure that sawn off parts of the tree do
not roll away.
◼ If working on a gradient, always stand and
work at the top of the gradient.
◼ Observe all safety instructions in connection
with potential kickbacks of the chainsaw.
◼ Estimate the bending force of the trunk
correctly before cutting to length. Always
start the cut on the opposite side of the
bend so that the guide rail of the chainsaw
does not become trapped.
Cutting trunks on flat ground
◼ Cut the trunk halfway through.
◼ Turn the trunk over.
◼ Cut through the trunk from the opposite
side.
