erwise the cutting attachment may stick in the cut
or kick back – risk of injury!
► Make relieving cut at the compression side (1)
► Make bucking cut at the tension side (2)
Be wary of pushback when making bucking cut
from the bottom upwards (underbuck).
NOTICE
Do not cut a lying log at a point where it is touch‐
ing the ground because the saw chain will other‐
wise be damaged.
Ripping:
Sawing technique without use of the spiked
bumper – risk of pull-in – position the guide bar at
as shallow an angle as possible – be especially
careful – increased risk of kickback!
4.2 Preparing for felling
Check that there are no other persons in the fell‐
ing area – other than helpers.
Make sure no-one is endangered by the falling
tree – the noise of your engine may drown any
warning calls.
Maintain a distance of at least 2 1/2 tree lengths
from the next felling site.
Determining direction of fall and escape path
Select gap in stand into which you want the tree
to fall.
Pay special attention to the following points:
–
The natural inclination of the tree
–
Unusually heavy limb structure, asymmetrical
growth, damage to tree
–
The wind direction and speed – do not fell 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 direc‐
tion of fall
