TOOL OPERATION

WARNING
The following are general woodcutting procedures
and techniques. Differences in the terrain, vegetation
and type of wood will make this information more or
less valid for particular areas. For adivce on specifi c
wood cutting problems or techniques for your area,
consult you local Stanley representative or your
county agent. They can often provide information that
will make your work safer and more productive.

CUTTING TIPS

1. Check the lean of the tree. tie a weight to a piece of
string about 2 feet long. Hang the weight in your line of
sight. the string is a good vertical line to help you judge
the lean of a tree. The tree should fall the way the string is
leaning. Trees that are straight (leaning no more than 5
generall can be felled in any direction.
2. Check the weight distribution. A tree is heavier on the
side with the most limbs. It will try to fall on its heavy side.
Trim a few limbs to balance the tree.
3. Clear the work area. You need a clean area all around
the tree. Get everything out of the area where the limbs
might fall. Do not cut trees near structures. Because of the
danger of electrocu tion, use extreme care when cutting
trees near power lines.
4. The chain saw should cut with very little pressure applied
to the handle. If you have to force the cut or if the cut is not
straight, cease cutting immediately to prevent further saw
chain and bar damage. See the MAINTENANCE AND AD-
JUSTMENTS section in this manual for chain replacement,
sharpening or adjustment proce dures.

FELLING OR TOPPING

1. Observe safety precautions.

NOTCHING OR UNDERCUTTING

2. The notching or undercutting cut is made on the side you
want the gree to fall.
3. Start the cut horizontally. Cut to about one-quarter of the
tree's diameter.
OPERATION
4. Make a diagonal cut down to meet the horizontal cut and
remove the wood from the notch.

FELLING OR BACK CUT

5. the felling or back cut is made on the side opposite and
at least 2-inches above the horizontal undercut (the felling
cut is made higher as the size of the tree increases).
6. Start the cut horizontally parallel to the notch cut. Cut un-
til the saw is about 1- or 2-inches from the notch. DO NOT
CUT THROUGH THE NOTCH.
Note:
The uncut wood between the felling and notch cuts is
called the hinge. The hinge controls the fall of the tree
and should be of uniform thickness.
o )
7. As the saw nears the back cut, watch the tree-top and
the cut for signs of meovement. Be alert as soon as the
tree starts to move, turn off the saw, pull it from the tree and
move away quickly on your escape route.

LOGS/LIMBS WITH PRESSURE ON BOTTOM

1. Observe all safety precautions.
2. Begin with a bottom-cut. The depth of the cut should be
about one-third of the log diameter.
3. Finish with an upper cut, down from the top. The saw
cuts should meet.
PRUNING & TRIMMING
1. Observe all safety precautions.
