It is extremely important that the chain brake be checked
for proper operation before each use and that the chain be
sharp in order to maintain the kickback safety level of this
saw. Removal of the safety devices, inadequate
maintenance, or incorrect replacement of the bar or chain
may increase the risk or serious personal injury due to
kickback.

FELLING A TREE(F20)
1. Decide the felling direction considering the wind, lean of the
tree, location of heavy branches, ease of job after felling and
other factors
2. While cleaning the area around the tree, arrange a good
foothold and retreat path.
3. Make a notch cut one-third of the way into the tree on the
felling side.
4. Make a felling cut from the opposite side of the notch and at
a level slightly higher than the bottom of the notch.
When you fell a tree, be sure to warn your neighbouring
workers of the danger.

Bucking and limbing
Bucking is the process of cutting the tree into usable lengths,
limbing is removing unwanted limbs(branches) from standing
timber or a tree that is lying on the ground. Both procedures
run the risk of kick back if the chainsaw is not held correctly
or held with one hand only. Warning there is an extreme
danger of kickback or that the saw will skate or bounce on
contact with an uneven part of the branch or log. Never work
with the nose of the bar in either action. When bucking never
stand on the log and make sure that avoid running the
chainsaw in to the ground.
●
Always ensure your foothold. Do not stand on the log.

Be alert to the rolling over of a cut log. Especially when
