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 specic situations, which
may depend on di erences 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 specic
woodcutting problems in your area. This will
make your work
more e 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 o the engine 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. 18)
Fig. 18
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. 19)
Fig. 19
There is a risk of kickback if the saw is pushed far enough so that
you begin to cut with the nose of the bar.
The safest cutting method is to cut with the bottom part of the
chain. Sawing with the upper part makes it much more
di cult to
control the saw and increases the risk of kickback.
