Chain Catcher; Basic Techniques For Making Felling, Limbing And Bucking Cuts - Tanaka TCS 33EB Mode D'emploi

English

Chain catcher

The chain catcher is located on the power head just
below the chain to further prevent the possibility of a
broken chain striking the chain saw user.
WARNING
Do not stand in-line with chain when cutting.
Basic techniques for making felling,
limbing and bucking cuts
The intention of the following information is to provide
you with the general introduction to wood cutting
techniques.
WARNING
○ This information does not cover all specific
situations, which may depend on differences in
terrain, vegetation, kind of wood, form and size of
trees, etc. Consult your servicing dealer, forestry
agent or local forestry schools for advice on specifi c
woodcutting problems in your area. This will make
your work more effi cient and safer.
○ Avoid cutting in adverse weather conditions, such as
dense fog, heavy rain, bitter cold, high winds, etc.
Adverse weather is often tiring to work in and creates
potentially dangerous conditions such as slippery
ground.
High winds may force the tree to fall in an unexpected
direction causing property damage or personal
injury.
CAUTION
Never use a chain saw to pry or for any purpose for
which it is not intended.
WARNING
○ Avoid stumbling on obstacles such as stumps, roots,
rocks, branches and fallen trees. Watch out for holes
and ditches. Be extremely cautious when working
on slopes or uneven ground.
Shut off the saw when moving from one work place
to another.
Always cut at wide open throttle. A slow moving
chain can easily catch and force the saw to jerk.
○ Never use the saw with only one hand.
You cannot control the saw properly and you may
lose control and injure yourself severely.
Keep the saw body close to your body to improve
control and reduce strain.
When cutting with the bottom part of the chain
the reactive force will pull the saw away from you
towards the wood you are cutting.
The saw will control the feeding speed and sawdust
will be directed towards you. (Fig. 22)

○ When cutting with the upper part of the chain the
reactive force will push the saw towards you and
away from the wood you are cutting. (Fig. 23)
○ There is a risk of kickback if the saw is pushed far
enough so that you begin to cut with the nose of the
guide bar.
The safest cutting method is to cut with the bottom
part of the chain. Sawing with the upper part makes it
much more diffi cult to control the saw and increases
the risk of kickback.
○ In case the chain locked, immediately release the
throttle trigger.
If the throttle trigger keeps rotating at high speed with
the chain locked, the clutch will overheat causing
trouble.
NOTE
Always keep the spiked bumper face to a tree,
because the chain may suddenly be drawn into a
tree, if so equipped.
Felling
Felling is more than cutting down a tree. You must also
bring it down as near to an intended place as possible
without damaging the tree or anything else.
Before felling a tree, carefully consider all conditions
which may eff ect the intended direction, such as:
Angle of the tree. Shape of the crown. Snow load on
the crown.
Wind conditions. Obstacles within tree range (e.g., other
trees, power lines, roads, buildings, etc.).
WARNING
○ Always observe the general conditions of the tree.
Look for decay and rot in the trunk which will make it
more likely to snap and start to fall before you expect
it.
