OPERATING TIPS
S Check chain tension before first use, 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 , non-wood buildin g materials, etc.
S Stop the saw if the chain strikes a foreign
object. Inspect the saw and repair or re-
place par ts as necessary. If the chain
jumps off t he guide bar, inspect the chain
for damageddrive links beforereinstalling.
Burrs on drive links, which prevent them
from entering the groove of t he guide bar,
can be rem oved with a flat file.
S Keep the chain out of dirt and sand. Even a
small amount of dirt will dull a chain, increase
the possibility of kickback, and require chain
sharpening o r replacement.
S Practice cutting a few small lo gs using the
following techniques to get the“feel” of us-
ing your saw before you begin a major
sawing operation.
S Squeeze the throttle trigger and allow the
engine to reach full speed before cutting.
S Begin cutting with the saw frame
against the log.
S Keep the engine at fullspeed the entire
time you are cutting.
S Allow thechaintocut f oryou. Exertonly
light downward pressure. If you force
the cut,damage tothe bar,chain, oren-
gine can result.
S Release the throttle trigger 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 avoid l osing control when cut i s com-
plete, do not put pressure on saw at end
of cut.
S Stop the engine before setting the saw
down after cutting.

ale to see well, nor during bad weather suchas
rain, snow , or strong winds, etc. If the tree
