OPERATING TIPS
S Check chain tension bef ore first us e, after
1 minute of operation, and each time be-
fore you start the chain saw. See CHAIN
TENSION in the ASSEMBLY section.
S Cut wood only. Do not cut metal, plastics,
masonry , n on-wood b ui ldin g m aterials, e tc.
S Stop the saw if the chain strikes a for eign
object. Inspect the saw and repair or re-
place parts as necessary. If the chain
jumps off the guide bar, inspect the chain
for damageddrive links beforereinstalling.
Burrs on drive links, which prevent them
from entering the groove of the guide bar,
can be removed with a flat file.
S Keep t he chain out of dirt and sand. Even a
small amount of dirt will dull achain, increase
the possibility of kickback, a nd require chain
sharpening or replacement.
S Practice cutting a few smalllogs using the
following techniques to get the“feel” of us-
ing your saw before you begin a m ajor
sawing operation.
S Squeeze t he throttle trigger and a llow the
engine to reach full speed bef ore cutting.
S Begin cutting with the saw frame
against the log.
S Keep theengine at full speed the entire
time you are cutting.
S Allowthe chaintocutforyou.Exertonly
light downward pressure. If you force
the cut,damage tothe bar,chain,oren-
gine can result.
S Release t he throttle tr igger as soon as
the cut is completed, allowing the en-
gine to idle. If you run the saw at full
throttle without acutting load,unneces-
sary wear can occur to the chain, bar,
and engine. It is recommended that
the engine not be operated for lon-
ger than 30 seconds at full throttle.
S To a void losing control when cut is com-
plete, do not put pressure on saw at end
of cut.
S Stop the engine before setting the saw
down a fter cutting.
TREE FELLING TECHNIQUES
WARNING: Check f or broken or dead
branches which can fall while cutting causing
serious injury.Do notcut near buildings or elec-
trical wires if you do not know the direction of
tree fall, nor c ut at night sinceyou willnot beale
to see well, nor during bad weather such as
rain, snow, or strong winds, etc. If the tree
makes contact with any utility line, the utility
company should b e notified immediately.
S Carefullyplanyoursawingoperation inad-
vance.
S Cleartheworkarea. Youneeda cleararea
allaroundthe treeso you can have secure
footing.
S The chain saw operator should keep on
the uphill side of the t errain as the tree is
likely torollor slidedownhillafterit isfelled.
S Study the natural conditions that can cause
the tree to fall in a particular direction.
Natural conditions that can cause a tree to
fall in a particular direction include:
S The wind dir ection and speed.
S The lean of the tree. The lean of a tree
might not be apparent due to uneven or
sloping terrain. Usea plumb o rlevel tode-
termine the direction of tree lean.
S Weight and branches o n one side.
S Surrounding tr ees and obstacles.
Look for decay and rot. If the trunk is rotted,
it can snap and fall toward the operator.
Check for broken or dead branches which
can fall on you while cutting.
Make sure there is enough room for the t ree to
fall. Maintain a distance of
2-1/2 tree lengths
from the nearest person o r other objects. En-
gine noise can drown out a warning call.
Remove dirt, stones, loose bark, nails, sta-
ples, andwirefrom thetree wherecuts areto
be made.

onal t o the line of fall.
