WARNING: When performing the fol­
lowing procedure, the engine must be turned
The chain brake must be checked several
times daily. Hold the chain saw approximate­
ly 14’’ {35 cm) above a stump or otherfirm ob­
ject. Release your grip on the front handle
and let the saw, by its own weight, rotate
around the rear handle. When the tip of the
bar hits the stump, the brake should activate.
UTTING METHOD
IMPORTANT POINTS
• Check chain tension before first use and
after 1 minute of operation. See CHAIN
TENSION in the ASSEMBLY section.
• Cut wood only Do not cut metal, plastics,
masonry, non-wood building materials, etc.
• Stop the saw if the chain strikes a foreign
object. I nspect the saw and repair parts as
necessary.
• Keepthechainoutofdirtandsand. Evena
small amount of dirt will quickly dull a chain
and increase the possibility of kickback.
• Practice cutting a few small logs using the
followingtechniques to get the “feel" of us­
ing your saw before you begin a major
sawing operation.
•
Squeeze the throttle trigger and allow
the engine to reach full speed before
cutting.
• Begin cutting with the saw frame
againstthe log.
• Keep the engine at full speed the en­
tire time you are cutting.
• Allow the chain to cut for you. Exert
only light downward pressure.
• Release the throttle triggeras soon as
the cut is completed, allowing the en­
gine to idle. If you run the saw at full
throttle without a cutting load, unnec­
essary wear can occur.
• To avoid losing control when cut is
complete, do not put pressure on saw
at end of cut.
• Stop the engine before setting the saw
down after cutting.
TREE FELLING TECHNIQUES
^WARNING: Check for broken or
dead branches which can fail while cutting
causingserious injury. Do not cut nearbuild­
ings or electrical wires if you do not know the
directionof tree fall, norcut atnightsinceyou
will not be ale to see well, nor during bad
weathersuch as rain, snow, or strong winds,
etc. If the tree makes contact with any utility
line, the utility company should be notified
immediately.
• Carefully plan your sawingoperation In ad­
vance.
• Clearthe work area. Youneedacleararea
all around the tree so you can have secure
footing.
• The chain saw operator should keep on
the uphill side of the terrain as the tree is
likely to roll or slide downhill afterit is felled.
* Study the natural conditions that can cause
the tree to fell in a particular direction.
Natural conditions that can cause a tree to
fall in a particular direction include:
* The wind direction and speed.
* The lean of the tree. The lean of a tree
might not be apparent due to uneven or
sloping terrain. Use a plumb or level to de­
termine the direction of tree lean.
* Weight and branches on one side.
* Surrounding trees and obstacles.
Look for decay and rot. If the trunk is rotted,
it can snap and fail toward the operator.
Check for broken or dead branches which
can fall on you while cutting.
Make sure there is enough room for the tree to
fell. Maintain a distance of 2 - 1/2 tree lengths
from the nearest person or other objects. En­
gine noise can drown out a warning call.
Remove dirt, stones, loose bark, nails, sta­
ples, and wire from the tree where cuts are to
be made.
Plana clear retreat path to the rear and diag­
onal to the line of fall.

FELLING LARGE TREES
(15 cm in diameter or larger)
The notch method is used to fell large trees.
A notch is cut on the side of the tree in the de­
sired direction of fall. After a felling cut is
made on the opposite side of tree, the tree
will tend to fail Into the notch.
NOTE: If the tree has large buttress roots,
remove them before making the notch. If us­
ing saw to remove buttress roots, keep saw
cha i n from contact! ng grou nd to p revent dull­
ing of the chain.
NOTCH CUT AND FELLING THE
TREE
• Make notch cut by cutting the top of the
notch first. Cut through 1/3 of the diameter
of the tree. Next complete the notch by cut­
ting the bottom of the notch. See lliustra-
tion. Once the notch is cut remove the
notch of wood from the tree.
