Proper Cutting Stance
• Weight should be balanced with both feet on
solid ground.
• Keep your left arm and elbow locked in a "straight arm"
position to withstand any kickback force (Fig. 11).
• Your body should always be to the left of the chain line.
Basic Cutting Procedures
m
WARNING!
This unit is designed for trimming branches
and limbs up to recommended 8.5 in. (21.6 cm), not to exceed
a max. cut of 9.5 in. (24.1 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 wood with the saw
turned off (Fig. 10).
• Squeeze the trigger switch and let the chain accelerate to
full speed before entering the cut.
• Hold the saw with both hands firmly. Always keep your left
hand on the front handle and your right hand on the rear
handle so that your body is to the left of the chain line.
• Keep the unit running the entire time you are cutting,
maintaining a steady speed.
• Let the chain do the work; exert only light downward
pressure. If you force the cut, damage to the bar, chain, or
unit can result.
• Do not put the pressure on the saw at the end of the cut.
• Always cut with both feet on solid ground to prevent falling.
• Do not cut above chest height since it is difficult to
control kickback forces with a saw held high.
Cutting Techniques
Before felling or delimbing for the first time, practice sawing
logs on the ground or on trestles, so that you can get familiar
with the machine and the most suitable sawing techniques.
m
WARNING!
Always hold the machine with both hands
when sawing.
m
WARNING!
Stop the motor immediately if the chain
stops during sawing. Beware of kickback, which can occur if
the bar contacts an obstacle.
• Felling a tree
i)
When bucking and felling are performed by two or more
people at the same time, the felling operation should be
separated from the bucking operation by a distance of at
least twice the height of the tree being felled. Trees should
not be felled in a manner that would endanger any person,
strike any utility line or cause any property damage. If the
tree does make contact with any utility line, the company
should be notified immediately.
ii)
The chain saw operator should keep on the uphill side of
the terrain as the tree is likely to roll or slide downhill after
it is felled.
iii)
An escape path should be planned and cleared as
necessary before cuts are started. The escape path should
extend back and diagonally to the rear of the expected
line of fall as illustrated (Fig. 12).
iv) Before felling is started, consider the natural lean of the
tree, the location of larger branches and the wind direction
to help you judge which way the tree will fall.
v)
Remove dirt, stones, loose bark, nails, staples and wire
from the tree.
• Notching undercut
Make the notch 1/3 the diameter of the tree, perpendicular to
the direction of the fall as illustrated (Fig. 13).
