• The most typical cutting application is to position the unit at
an angle of 60° or less depending on the specific situation
(Fig. 26). As the angle of the pole chain saw shaft to the
ground increases, the difficulty of making the first cut
(from the underside of limb) increases.

Basic Cutting Procedure
This unit with the chain saw head is designed for trimming small
branches and limbs up to recommended 6.5 in. (16.5 cm), not
to exceed a Max. cut of 7.5 in. (19 cm) in diameter depending
on type of wood. Practice cutting a few small limbs using the
following technique to get the "feel" of using the saw before you
begin a major sawing operation.
• Take the proper stance in front of the tree with the
saw OFF (Fig. 26).
• Switch on the pole chain saw and let the chain accelerate
to full speed before entering the cut.
• Keep the saw running the entire time you are cutting;
maintain a steady speed.
• Allow the chain to cut for you; exert only light downward
pressure. If you force the cut, damage to the bar, chain, or
unit can result.
• PUSH and PULL – This reaction force is always opposite
to the direction the chain is moving when it is in contact
with the wood. Thus, the operator must be ready to control
the PULL when cutting on the bottom edge of the bar, and
PUSH when cutting along the top edge.
• Do not put pressure on the saw at the end of the cut.
Pruning
Pruning is the process of trimming limbs from a live tree.
• Remove long branches in several stages.
• Cut lower branches first to allow the top branches more
room to fall.
• When pruning trees, it is important not to make the finishing
cut next to the main limb or trunk until you have cut off the
farthest lying limb. This will reduce the weight and prevent
stripping the bark from the main member.
• Under cut the branch 1/3 through for your first cut.
Your second cut should over cut to drop the branch off
(Fig. 27). Be prepared to balance the weight of the pole
chain saw when the limb falls.

• Now make your finishing cut from the topside of the branch
smoothly and neatly against the main member so the bark
will grow back to seal the wound.
• Release the On/Off switch as soon as the cut is completed.
Failure to follow proper cutting procedures will result in the
bar and chain binding and becoming pinched or trapped in
the limb.
Limbing
Limbing is the process of removing branches from a fallen tree.
• You should cut limbs one at a time. Remove the cut limbs
from the work area often to help keep the work area clean
and safe.
• Cut branches under tension from the bottom up to avoid
binding the bar and chain.
• Keep the tree between you and the pole chain saw while
limbing. Cut from the side of the tree opposite the branch
you are cutting.
If the Saw Becomes Pinched or Trapped
1. Wait for the blade to stop, wait five minutes for the saw to
cool, remove the battery, and wear gloves to protect your
hands from the chain teeth.
2. If you can reach the limb from the ground, lift the limb while
holding the saw. This should release the "pinch" and free
the saw.
3. If the saw is still trapped, call a professional for assistance.
