General Suggestions For Cutting; Felling A Tree - Wolf Garten CSE 2240 Bedienungsanleitung

11.GENERAL SUGGESTIONS FOR
CUTTING
We recommend to cut by using the bottom of
the bar, a technique to pull the chain, so the
electric chainsaw tends to move towards the
trunk, decreasing the danger for the operator.
Be careful when cutting with the top of the bar,
because the electric chain saw would tend to
move towards the operator.
# Make sure to the cutting length.
# Avoid cutting of thin twigs and bushes.
The twigs can be grabbed by the chain, set in
rotation and cause injury.
# Pay particular attention to branches in
tension: they might be dangerous for the
operator.
# Be especially careful when working on slopes,
uneven and slippery ground.
# Do not cut wire mesh.
# Do not proceed with detailed jobs without first
having made the necessary experience.
In case of doubt and uncertainty, consult an
expert.
# It is recommended to cut logs upon tripods
or clamps to gain experience.
CUTTING LOGS
Cutting a log resting on the two
extremities
FIG. 12
# First cut 1/3 of a diameter from the top.
Next cut from below using the top of the bar.
This will avoid pinching of the bar in wood. Avoid
touching the ground with the bar.
Cutting from a saw horse
FIG. 13
# First cut 1/3 of a diameter from below.
Next cut from the top using the bottom of
the bar.

FELLING A TREE

# Before felling a tree, consider carefully all
conditions including the intended direction of
the fall, the natural lean of the tree, surrounding
trees and obstacles, the wind direction and
speed.
Directional cut
FIG. 14
# Cut a wedge (1/3-1/2 of tree diameter) out
of the trunk on the side which you want the
tree to fall.
Felling cut
FIG. 15 - 16
# Cut into the trunk from the other side 1"- 2"/3-6
cm above the wedge.
# Use a felling wedge to help control felling
and prevent binding the guide bar and saw
chain in the cut.
# Safety distance is 2.5 times the height of the
tree to fell. Be sure that nobody is in the danger
zone before and during the felling.
CUTTING PREPARED TIMBER
# When cutting prepared, use clamps or shocks
to secure wood.
