CS-310 OPERATION
To fell big trees with a diameter exceeding twice the bar length,
start the notching cuts from one side and draw the saw through
3
to the other side of the notch. Start the back cut on one side of
the tree, pivoting the saw through to form the desired hinge on
1
that side. Then remove the saw for the second cut. Insert the
saw in the first cut, very carefully so as not to cause kickback.

The final cut is made by drawing the saw forward in the cut to
reach the hinge.
Limbing
Limbing a fallen tree is much the same as bucking. Never stand
on the tree that you are limbing. When limbing, caution is the
word. Be careful of the tip touching other limbs. Always use
both hands.
Don't cut with the saw overhead or aligned vertically with your
body. If the saw should kickback, you may not have enough
control to prevent possible injury.
Bucking
Bucking is the sawing of a log or fallen tree into smaller pieces.
There are a few basic rules which apply to all bucking

operations.
• Keep both hands on the handles at all times.
• Support logs if possible.
• When cutting on a slope or hillside, always stand uphill.
Finish cut
Keep in mind that the wood is heavy and that it will bend and
pinch the saw if improperly supported. The trunk will weaken at
the point where you make the cut unless the tree is lying on

perfectly flat ground or supported as shown. If you make the
cut with the tree on the ground, don't let the saw's chain dig into

the earth; it is harmful for the saw, and you stand a good
chance of being struck by flying debris.
