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 chainsaw as shown below. 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: Recommend that first‑time users should
practice cutting on a saw horse.
Cutting a felled tree or log into lengths. How you should
cut depends on how the log is supported. Use a saw horse
whenever possible as shown below.
1. Always start a cut with the saw chain running at
full speed.
2. Place the bottom spike
area of the initial cut as shown below.
3. Turn the chainsaw on then rotate the saw chain and bar
down into the tree, using the spike as a hinge.

chainsaw again and repeat steps until you cut
fully through.
5. 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.

• When supported at one end first, cut 1/3 the diameter
from the underside (underbuck). Then make the finishing
cut by overbucking to meet the first cut as shown below.

• When supported at both ends. First, cut 1/3 down from the
top overbuck. Then make the finished cut by underbucking
the lower 2/3 to meet the first cut as shown below.
• When on a slope always stand on the uphill side of the
log. When "cutting through", to maintain complete
control reduce 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 cut to cut.
