Working behavior/Method of
working
- Only use the chain saw during good light and
visibility periods. Be aware of slippery or wet areas,
and of ice and snow (risk of slipping). The risk of
slipping is extremely high when working on recently
peeled wood (bark).
- Never work on unstable surfaces. Make sure
that there are no obstacles in the working area,
risk of stumbling. Always ensure that you have a
safe footing.
- Never saw above your shoulder height.
- Never saw while standing on a ladder .
- Never climb a tree and work without the
appropriate restraining systems for the operator
and the saw. We recommend always working
from a rising platform (cherry picker, lift).
- Do not work leaning too far over.
- Guide the chain saw in such a way that no part of
your body is within the elongated swivelling range of
the saw .
- Use the chain saw for sawing wood only.
- Avoid touching the ground with the chain saw
while it is still running.
- Never use the chain saw for lifting up or removing
pieces of wood or other objects.
- Remove foreign objects such as sand, stones
and nails found within the working area. Foreign
objects may damage the sawing device and can
cause dangerous kickback.
- When sawing precut timber use a safe
support (sawing jack). Do not
steady the workpiece with your foot, and do not
allow anyone else to hold or steady it.
- Secure round pieces against rotation.
- Before performing a crosscut firmly apply the
front of the body to the timber, only then can the
timber be cut with the chain running. For this the
chain saw is lifted at the rear handle and guided
with the tubular handle. The front of the body serves
as a centre of rotation. Continue by slightly
pressing down the tubular handle and
simultaneously pulling back the chain saw. Apply
the front of the body a little bit deeper and once
again lift the rear handle.
- When the timber must be pierced for cutting or
longitudinal cuts are to be performed it is urgently
recommended to have this carried out by specially
trained persons only (high risk of kickback).
- Do longitudinal - lengthwise - cuts at the
lowest possible angle. Be very careful when doing
this type of cut, as the front body cannot grip.
- The saw must be running whenever you remove
the chain saw from the wood.
- When performing several cuts the throttle lever
must be released in between.
- Be careful when cutting splintery wood. Cut
pieces of wood may be pulled along (risk of
injuries).
- When cutting with the upper edge of the guide
bar, the chain saw may be pushed in the direction of
the user if the chain gets clamped. For this reason
use the lower edge of the bar whenever possible.
The chain saw will then be pushed away from
you.
- If the timber is under tension, first cut the
pressure side. Then the crosscut can be performed
on the tension side. Thus clamping of the guide bar
can be avoided.
CAUTION:
People felling trees or cutting of branches must be
specially trained. High risk
of injuries!
- When cutting of branches, the chain saw should
be supported on the trunk. Do not use the end of the
bar for cutting (risk of kickback).
- Be aware of branches under tension. Do not cut
free branches from below.
- Never perform detensioning cuts while standing
on the trunk.
- Before cutting down a tree ensure that
a) only those people are within the working area
which are actually involved in cutting down the tree.
b) every worker involved can withdraw without
stumbling (the people should withdraw backwards in
a diagonal line, i. e. at a degree of 45° ).
c) the bottom part of the trunk is free from
foreign objects, underbrush and branches. Make
sure to have a safe footing (risk of stumbling).
d) the next working place is at least 2 1/2 tree
lengths away. Before cutting down the tree check
the direction of fall and make sure that there are nei-
ther people nor objects within a distance of 2 1/2
tree lengths.
- Judging the tree:
Direction of hanging - loose or dry branches - height
of the tree - natural overhang
- is the tree rotten?
- Take into account the direction and speed of the
wind. If strong gusts are occurring, do not do any
felling. Avoid sawdust (pay attention to the direction
the wind is blowing)!
- Cutting the roots:
Start with the strongest root. First do the vertical and
then the horizontal cut.
- Notching the trunk:
The notch determines the direction of fall and
guides the tree. The trunk is notched
perpendicular to the direction of fall and penetrates
1/3 – 1/5 of the trunk diameter.
Perform the cut near the ground.
- When correcting the cut, always do so over the
whole width of the notch.
- Cut down the tree above the bottom edge of the
notch. The cut must be exactly horizontal. The
distance between both cuts must be approx. 1/10
of the trunk diameter.
- The material between both cuts serves as a
hinge. Never cut it through, otherwise the tree will
fall without any control. Insert felling wedges in time.
- Secure the cut only with wedges made of plastic
or aluminium. Do not use iron wedges. If the saw
hits an iron wedge the chain can be seriously
damaged or torn.
- When cutting down a tree always stay sidewards
of the falling tree.
- When withdrawing after having performed the
cut, be alert for falling branches.
- When working on sloping ground the user of
the chain saw must stay above or sidewards of the
trunk to be cut or the tree already cut down.
- Be alert for trunks which may roll towards you.
Transport and storage
- When changing your location during work switch
off the chain saw and actuate the chain brake in
order to prevent an inadvertent start of the chain.
- Never carry or transport the chain saw with the
chain running.
