Kickback; Working Behavior/Method Of Working - Makita DCS9010 Instruction Manual

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 ob-
jects (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 re-
commended 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 it
with your foot.
- For cutting down trees or performing crosscuts the toot hed
ledge (13,Z) must be applied to the wood to be cut.
- Before performing a crosscut Þ rmly 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.
