3. Your body should always be to the left of the chain line.
Basic Cutting Procedures
1. Small trees up to 6 – 7 inches in diameters are usually cut
in a single cut. Notch cuts determine the direction the tree
will fall.
m
WARNING!
If the tree starts to fall in a wrong direction,
or if the saw got caught or hung up during the fall, leave the
saw and save yourself.
m
WARNING!
Periodically glance at the top of the tree
during the back-cut to ensure the tree is going to fall in the
desired direction.
2. Practice cutting a few small logs using the following
techniques to get the feel of using the saw before you
begin a major sawing operation.
3. Take the proper stance in front of the wood with the saw
turned off.
4. Squeeze the trigger and let the chain accelerate to full
speed before entering the cut.
5. 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.
6. Keep the unit running the entire time you are cutting,
maintaining a steady speed.
7. 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.
8. Do not put the pressure on the saw at the end of the cut.
9. Always cut with both feet on solid ground to prevent
falling.
10. 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.
When felling a tree, keep everyone a safe distance from the
cutting area. The safest distance should be at least twice the
height of the largest trees in the felling area.

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 any manner that could endanger a person,
strike a utility line, or cause property damage. If the tree
does make contact with a utility line, the utility company
should be notified immediately.

Check the tree for damaged or dead

help you judge the direction in which the tree will fall.
WARNING!
Do not fell trees during periods of high wind
