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

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
–
45°
(e.g., with an axe) – sand, stones
and other foreign objects will blunt
the saw chain
45°
Remove large buttresses: remove
–
the largest buttress first – saw first
vertically, then horizontally – only if
the tree is in sound condition
