off balance and result in serious injury. Do not rely exclusively
upon the safety devices built into the saw. As a user, you
should take several precautions to keep your cutting jobs free
from accident or injury.
Proper Cutting Stance
•
Balance your weight with both feet on solid ground.
•
Your body should always be to the left of the chain line.
•
The most typical cutting application is to position the
unit at an angle of 60° or less depending on the specific
situation (Fig. 23). 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. 23).
• Squeeze the On/Off trigger switch
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. 24). Be prepared to balance the weight of the pole
chain saw when the limb falls.
• When re-starting the motor, always keep the ON/Off
trigger switch pressed.
NOTE: The motor only runs when the
ON/Off trigger
switch
is operated and shuts off when the ON/Off trigger
switch is released.
• 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 trigger 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.
