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
Felling notch
Preparing the felling notch
The felling notch (C) determines the
direction of fall.
Important:
–
Make a felling notch at right angle to
direction of fall
–
Saw as close to the ground as
possible
–
Cut to a depth of approx. 1/5 to 1/3
of the diameter of the trunk
Specify the direction of fall – without the
gunning sight on the shroud and fan
housing
If the chain saw is designed without the
gunning sight on the shroud and fan
housing, the direction of fall can be
determined or controlled using a meter
