direction. Do not cut through the hinge.
• (figure l) As the felling cut gets close to
the hinge the tree should begin to fall. If
there is any chance that the tree may not
fall in the desired direction or it may rock
back and bind the saw chain, stop cutting
before the felling cut is complete and
use wedges 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.

liMBing

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. Branches under
tension should be cut from the bottom of
the branch towards the top to avoid binding
the chain saw as shown in figure M.
Trim limbs from opposite side keeping
tree stem between you and saw. Never
make cuts with saw between your legs or
straddle the limb to be cut.

warning:

Cutting a felled tree or log into lengths.

• Turn the chain saw on then rotate the
chain and bar down into the tree, using
the spike as a hinge.
• Once the chain saw gets to a 45 degree
angle, level the chain saw again and
repeat steps until you cut fully through.
• when the tree is supported along its
entire length, make a cut from the top
(overbuck), but avoid cutting the earth as
this will dull your saw quickly.
• figure p- when supported at one end
First, cut 1/3 the diameter from the
underside (underbuck). Then make the
finished cut by overbucking to meet the

Always stand on the uphill side of the
log. 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
