3. Felling back cut cont.
As the felling gets close to the

hinge, the tree should begin to fall.
If there is any chance that the tree

may not fall in desired direction or

it may rock back and bind the saw

chain, stop cutting before the felling

back cut is complete and use wedges

of wood, plastic or aluminium to

open the cut and drop the tree along

the desired line of fall.
When the tree begins to fall remove the chain saw from the cut, stop the motor, put the chain

saw down, then use the retreat path planned.
Be alert for overhead limbs falling and watch your footing.

Fig. A.

4. Limbing a tree 
Limbing is removing the branches

from a fallen tree. When limbing leave

larger lower limbs to support the log

off the ground. Remove the small

limbs in one cut as illustrated in

Fig. B.  Branches under tension

should be cut from the bottom up

to avoid binding the chain saw.

Fig. B.

5. Bucking a log
Bucking is cutting a log into lengths. It is important to make

sure your footing is firm and your weight is evenly distributed

on both feet. When possible, the log should be raised and

supported by the use of limbs, logs or chocks.

Follow the simple directions for easy cutting. 

When the log is supported along its entire length

as illustrated in

 Fig. C., it is cut from the top (overbuck). 

Fig. C.

Bucking a log cont.

When the log is supported on one end,
as illustrated in 

Fig. D., cut 1/3 the diameter from

the underside (underbuck).
Then make the finished cut by overbucking
to meet the first cut.

When the log is supported on both ends,
as illustrated in 

Fig. E, cut 1/3 the diameter from the

top (overbuck).
Then make the finished cut by underbucking
the lower 2/3 to meet the first cut. 

Fig. D.

Fig. E.

When bucking on a slope always stand on the
uphill side of the log, as illustrated in 

Fig. F.

When “cutting through”, to maintain complete
control release the cutting pressure near the end
of the cut without relaxing your grip on the chain
saw handles. Don’t let the chain contact the ground.
After completing the cut, wait for the saw chain to
stop before you move the chain saw.
Always stop the motor before moving from tree
to tree.
