•
Then start sawing from next point. Reserve the hinge part.
Take out the saw to continue cutting.
•
Insert the saw into the previous seam. Be careful of
bounce.
•
At last, pull the saw in the previous sawing direction to the
final position.
Branch cutting
Branches are sawed in the same way as trees. Do not stand on
trees to cut branches. Be careful of collision between the top of
the guide plate and other branches. Operate the chain saw with
both hands.
Finally saw
the supporting
branch.
Place the rolling log
under the trunk.
During branch cutting, the trunk and branches should be cut
longitudinally, transversely and obliquely, and a lot of branches
will be subject to bounce near the guide plate. Clean the site
before cutting. Be concentrated in cutting, and prevent the
collision against other branches in the bounce area of the guide
plate.
Be careful to cut elastic branches and trees. Control the
direction of bounce. Several gaps can be formed on parts which
may be easily subject to bounce, to release the force of bounce.
To cut the tree with a lot of branches, the rolling log can be
placed under the tree to increase external support, and
supporting branches should be left and cut at the end.
Do not cut branches higher than the chest
or keep the guide plate vertical in the
cutting process.
Otherwise, buffering cannot be realized
to prevent possible injury in case of
bounce of the chain saw.
Tree sawing
Do not stand on the log
in the cutting process.
Stand on the
uphill side in the
cutting process.
Rolling direction
Tree sawing refers to log cutting or tree splitting.
Observe the following suggestions during sorting and splitting
of trees:
•
Operate the chain saw with both hands in any case.
•
If possible, support the log at last.
•
Stand on the uphill side during cutting on the slope or at
the foot of the hill.
Warning
Danger
1. Do not stand on the log in the cutting process.
2. Stand on the uphill side in the cutting process.

Judge the pulling and pressing points of the long log on the
ground, according to main support points.
If the support points are at both ends, the
upper part of timber is pressed, while the
lower part is pulled.
In the process of cutting between the
two points, cut approximately 1/3 of the
diameter downwards and then upwards
in the same position.
