OPERATION
BASIC OPERATING/CUTTING PROCEDURES
Practice cutting a few small logs 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 idling.
Accelerate the engine to full throttle just before entering
the cut by squeezing the throttle trigger.
Begin cutting with the saw against the log.
Keep the engine at full throttle the entire time you are
cutting.
Allow the chain to cut for you; exert only light downward
pressure. Forcing the cut could result in damage to the
bar, chain, or engine.
Release the throttle trigger as soon as the cut is
completed allowing the engine to idle. Running the
saw at full throttle without a cutting load can result in
unnecessary wear to the chain, bar, and engine.
Do not put pressure on the saw at the end of the cut.
FELLING TREES – HAZARDOUS CONDITIONS (Fig.
20)
WARNING
Do not fell trees during periods of high wind or heavy
precipitation. Wait until the hazardous weather has
ended.
When felling a tree, it is important that you heed the following
warnings to prevent possible serious injury.
Wear eye, hearing, and head protection (A) when
operating this equipment.
Do not cut down trees having an extreme lean or large
trees with rotten or dead limbs, loose bark, or hollow
trunks. Have these trees pushed or dragged down with
heavy equipment, then cut them up.
Consider the distribution and weight of heavy limbs
(B).
Clear out the undergrowth around the tree to be felled
(C).
Do not cut trees near electrical wires or buildings (D).
Consider the direction in which the tree leans (E).
Check the tree for damaged or dead branches which
could fall and hit you during felling (F).

English
Periodically glance at the top of the tree during the
back-cut to assure the tree is going to fall in the desired
direction.
Keep all bystanders at a safe distance (G) (at least
twice the height of the tree).
Prepare a path of safe retreat (H).
If the tree starts to fall in the wrong direction, or if the
saw gets caught or hung up during the fall, leave the
saw and save yourself!
Consider the wind direction before felling a tree.
Do not fell trees near power lines or near buildings
which could be struck by falling limbs or the tree
itself.
The chainsaw operator should keep on the uphill side
of the terrain as the tree is likely to roll or slide downhill
after it is felled.
Remove dirt, stones, loose bark, nails, staples, and
wire from the tree where felling cuts are to be made.
PROPER PROCEDURE FOR TREE FELLING (Fig. 21
- 24)
1. Pick your escape route (or routes in case the intended
route is blocked). Clear the immediate area around the
tree and make sure there are no obstructions in your
planned path of retreat. Clear the path of safe retreat
approximately 135° from the planned line of fall (A).
2. Consider the force and direction of the wind, the lean
and balance of the tree, and the location of large limbs.
These things infl uence the direction in which the tree
will fall. Do not try to fell a tree along a line different
from its natural line of fall (B).
3. Cut a notch about 1/3 the diameter of the trunk in
the side of the tree (C). Make the notch cuts so they
intersect at right angles to the line of fall. This notch
should be cleaned out to leave a straight line.
To keep the weight of the wood off the saw, always
make the lower cut of the notch before the upper cut.
4. Make the back-cut (D) level and horizontal, and at
a minimum of 5 cm above the horizontal cut of the
notch.
