RISK OF KICKBACK
WARNING!
Kickback can occur if the tip or topside of the
bar comes into contact with wood or other
solid objects. The saw then kicks back, which
can cause fatal and/or serious personal injury.
• Always check before use that the chain
brake is working properly.
• Do not allow the tip of the bar to make
contact with wood or other solid objects.
FIG. 9
• The chain brake may not be applied
automatically in the event of minor
kickback. For this reason, always hold the
chain saw firmly with both hands.
• The correct and careful way of working is
the only reliable method of reducing the
risk of kickback.
SAWING TECHNIQUE
Sawing with a pulling chain
• With this technique sawing takes place with
the underside of the bar, from up and down,
so that the chain pulls the saw forwards
away from the user. This allows the front of
the saw to provide support and absorb the
force from the wood being sawn.
FIG. 10
• When sawing with a pulling chain the user
has much better control over the saw and
can more easily avoid kickback. This is the
preferred technique.
Sawing with a pushing chain
• With this technique sawing takes place with
the topside of the bar, from down and up,
so that the chain pushes the saw backwards
towards the user. If bar twists the chain saw
can throw back towards the user with great
force.
FIG. 11
• If the user does not withstand the pushing
force of the saw there is a risk of the tip of
the bar coming into contact with the wood,
which can cause kickback.
Felling trees
WARNING!
• Risk of personal injury.
• Felling and limbing should only be carried
out by qualified personnel – risk of fatal
and/or serious personal injury.
• Always stand to the side of the tree being
felled – risk of fatal and/or serious
personal injury.
Check the following points before
tree felling.
• Check that there are no people or animals
in the work area.
• Check that everyone involved in the work
has a clear retreat from the felling area.
Retreat (B) should run at an angle to the
direction of felling (A).
FIG. 12
• Check that the area around the tree is free
from obstructions that can be tripped over.
• Check that the nearest workplace is at least
2.5 tree heights away. Check the direction
in which the tree is going to fall and make
sure there are no people, animals or
obstacles within at least 2.5 tree heights.
Tree felling takes place in two steps.
1. Make a notch cut (1) through about 1/3
of the diameter of the tree, on the side in
which the tree is to fall.
2. Saw the felling cut (2) from the other side
of the tree, 3–5 cm above the bottom of
the notch cut. Always leave holding wood
(C), which acts as a hinge.
