5. Take the utmost care when cutting through
branches or logs that are in tension. A log or branch
that is in tension can suddenly spring back into its
natural position before or after you cut it. If you
stand on the wrong side or start cutting in the wrong
place it may strike you or your chain saw. This
could make you lose control and cause a serious
accident.
6. Before moving your chain saw switch off the engine
and lock the chain using the chain brake. Carry the
saw with the bar and chain pointing backwards. Fit
a guard to the bar before carrying the saw any
distance.
7. Never put a chain saw down while the engine is
running unless you have it in clear view and the
chain brake is on. Switch the engine off before
leaving your chain saw for any length of time.
Tree felling techniques
WARNING
It takes a lot of experience to fell a tree. Inexperienced
operators of chain saws should not fell trees. Never
attempt a task you are unsure of.
WARNING
Check for broken or dead branches which can fall while
cutting causing serious injury. Do not cut near buildings
or electrical wires if you do not know the direction of
tree fall, nor cut at night since you will not be ale to see
well, nor during bad weather such as rain, snow, or
strong winds, etc. If the tree makes contact with any
utility line, the utility company should be notified before
beginning to cut.
•
Carefully plan your sawing operation in advance.
•
Clear the work area. &u need a clear area all around
the tree so you can have secure footing.
•
The chain saw operator should keep on the uphill
side of the terrain as the tree is likely to roll or slide
downhill after it is felled.
•
Study the natural conditions that can cause the tree
to fall in a particular direction.
WARNING
During critical felling operations, hearing protectors
should be lifted immediately when sawing is completed
so that sounds and warning signals can be heard.
A. Safe distance
Make sure there is enough room for the tree to fall. The
safe distance between a tree that is to be felled and
anyone else working nearby is at least 2 1/2 tree
lengths. Maintain a distance of 2 1/2 tree lengths from
the nearest person or other objects. Engine noise can
drown out a warning call.
Make sure that no-one else is in this “risk zone” before
or during felling.
B. Felling direction
The aim is to fell the tree in the best possible position
for subsequent limbing and cross-cutting. You want it to
fall on ground where you can move about safely.
The main point to avoid is letting the tree fall onto
another tree. It can be both difficult and dangerous to
remove a tree in such a position.
Once you have decided which way you want the tree to
fall you must judge which way the tree would fall
