The distance to the next worksite must
be at least 2 1/2 tree lengths.
Specify the direction of fall and escape
paths
Select a gap in the timber stand into
which the tree can be felled.
Pay special attention to the following
points:
– The natural inclination of the tree
– Unusually heavy limb structure,
asymmetrical growth, damage to
tree
– Wind direction and speed – do not
fell trees in high winds
– Direction of slope
– Neighboring trees
– Snow load
– Take the general condition of the
tree into account – be especially
careful with trunk damage or
deadwood (brittle, rotten or dead
wood)
A Direction of fall
B Escape path (escape routes)
– Establish escape paths for each
worker – approx. 45° diagonally
opposite to the direction of fall
– Clear escape paths, eliminate
obstacles
– Put down tools and equipment at a
safe distance – but not on the
escape paths
– When felling, stand only to the side
of the falling trunk and only move
back laterally onto the escape path
– Plan escape paths on slopes
parallel to the slope
– When getting out of the way, watch
out for falling branches and the
crown area
Preparing the work area at the trunk
– Clear the work area at the trunk of
branches, brush and other
obstacles – secure footing for all
workers
– Carefully clear the base of the trunk
(e.g., with an axe) – sand, stones
and other foreign objects will blunt
the saw chain
– Remove large buttresses: remove
the largest buttress first – saw first
vertically, then horizontally – only if
the tree is in sound condition
