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
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 the limb stub at the branch collar
(Figure 14).
Important:
collar, flush to the trunk, or leave a large
limb stub; this damages the tree.
Figure 12.
Do not cut the limb past the
1. First relief undercut
2. Second through cut

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.
DANGER
Loose or tangled limbs above you may be
dislodged by vibration from cutting, causing
severe injury or death.
Always look overhead for loose and tangled
limbs before cutting; if you see any loose
limbs or branches, remove them before
cutting.
The proper operator stance for felling a tree is shown
in Figure 15.
