Note:
Keeping your left arm straight with your
elbow locked helps reduce kickback.

2. Stand to the left side of the chain saw and not
in line with the chain, and position yourself for
balanced, stable footing while sawing.
3. Stand on solid, even ground in front of the wood
to be cut.
4. While cutting, have the wood near the chain saw
head, at the exposed near end of the guide bar.
You can use the bucking teeth ( Figure 12 ) to add
pressure but it works best with a sharp-toothed
chain.

5. Press the chain saw lightly against the wood,
allowing the weight of the chain saw to drive the
cutting.
6. Keep steady pressure on the chain saw
throughout the cut, and release pressure only
near the end of the cut.
Pruning a Tree
WARNING
Cutting higher limbs from a tree off the ground
can put you in an unstable position that could
be unsafe for you while handling a chain saw,
resulting in possible serious personal injury
or death to you or bystanders.
When cutting limbs from a standing tree, use
the following practices:
• Do not climb on limbs or branches with a
chain saw.
• Do not overreach, and cut with both hands
on the chain saw.
• Ensure that all bystanders are away from
the area where branches may fall.
1. Grip the chain saw as shown in Figure 11 .
2. While cutting small branches, apply light
pressure to the branch to be cut.
3. While cutting larger branches, make a shallow
undercut and then complete the cut from the
topside of the branch.
A. Cut from the underside of the limb about 15
cm (6 inches) from the trunk. Cut a third of
the way through the limb.
B. Cut 5.0 to 10.0 cm (2 to 4 inches) farther
out on the limb and from above. Cut the
limb until it falls.
C. Cut about a third of the diameter of the limb
stub from underneath as close to the trunk
as possible.
D. Cut the limb stub from above so that it
meets the previous cut as close to the trunk
as possible.
Felling a Tree
WARNING
Cutting standing trees requires expertise and
poses hazards.
• Before attempting to cut a big tree, practice
cutting a few branches, limbs, or small logs
to familiarize yourself with the chain saw.
• Do not use this chain saw to fell large trees
with a diameter larger than the length of
the guide bar.
The proper operator stance for felling a tree is shown
in
Figure 13 .
