Kickback
- When working with the chain saw dangerous kickbacks
may occur.
-
Kickbacks are produced when the upper part of the end of
the guide bar inadvertently touches wood or other hard
objects (10).
-
In this case the chain saw is thrown without any control and
with high energy potentials in the direction of the user
(risk of injuries).
In order to prevent kickbacks follow the instructions
given below:
-
When timber must be pierced for cutting it is urgently
recommended to have these works carried out by specially
trained people only.
-
Never apply the end of the bar when starting to make a cut.
-
Always observe the end of the guide bar. Be careful when
continuing an already done cut.
-
When starting to cut the chain must be running.
-
Ensure that the chain is always sharpened correctly. Pay
special attention to the hight of the depth limiter.
-
Never cut several branches at the same time. When cutting
a branch ensure that no other branch is touched.
-
When crosscutting a trunk be aware of the trunks next to it.
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 (11).
-
Never saw while standing on a ladder.
-
Never climb up into trees to perform sawing with the chain
saw.
-
Never bend forward by far to perform sawing.
-
Guide the chain saw in such a way that no part of your body
is within the elongated swivelling range of the saw (12).
-
Use the chain saw for sawing wood only.
-
Avoid to touch 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 bodies such as sand, stones and nails found
within the working area. Foreign bodies may damage the
sawing device and can cause dangerous kickbacks.
-
When sawing precut timber use a safe support (sawing
jack, 13). Do not ask anyone to hold the wood, and do not
hold
with your foot.
-
For cutting down trees or performing crosscuts the
toothed ledge (13,Z) must be applied to the wood to
be cut.
-
Before performing a crosscut firmly apply the toothed
ledge to the timber, only then can the timber be cut with
the chain running. For this the chain saw is lifted at the back
handle and guided with the tubular handle. The toothed
ledge serves as a center of rotation. Continue by slightly
pressing down the tubular handle and simultaneously
pulling backwards the chain saw. Apply the toothed ledge
a little bit deeper and once again lift the back handle.
-
When the timber must be pierced for cutting or
longitudinal cuts are to be performed it is urgently
recommended to have these works carried out by
specially trained persons only (high risk of kickbacks).
-
For performing longitudinal cuts (14) apply the sawing
device at an angle which is as small as possible. Be very
careful when carrying out this kind of work because the
toothed ledge cannot be used.
-
The sawing device must be running whenever you remove
the chain saw from the timber.
-
When performing several cuts the throttle lever must be
released in between.
