automatically (by sudden movement).
SIf the brake is already activated, it is
disengagedby pulling the front hand guard
back toward the front handle as far as
possible.
SWhencutting with the s aw,the chain brake
must be disengaged.

Grip the rear handle with your right hand and
the front handle with your left hand. Hold the
chain saw approximately 14″(35 cm) above a
stump or other wooden surface. Release your

hits the stump, the brake should activate .
OPERATINGTIPS
SCheck chain tension before first use, after
1 minute of operation, and each time be-
fore you start the chain saw. See CHAIN
TENSIONin the ASSEMBLY section.
SCut wood only. Do not cut metal, plastics,
masonry,non-wood building materials, etc.
SStop the saw if the chain strikes a foreign
object. Inspect the saw and repair or re-
place parts as necessary. If the chain
jumps off the guide bar,inspect the chain
fordamaged drive links before reinstalling.
Burrs on drive links, which prevent them
from entering the groove of the guide bar,
can be removed with a flat file.
SKeep the chain out of dirt and sand. Ev ena
smallamount of dir t will dull a chain, increase
thepos sibility of kickback , and require chain
sharpening or replacement.
SPractice cutting a few small logs us ing the
followingtechniques to get the “feel” of us-
ing your saw before you begin a major
sawing operation.
SSqueeze the throttle trigger and allow the
engine to reach full speed before cutting.
SBegin cutting with the saw frame
against the log.
SKeepthe engine at full speed the entir e
timey ou are cutting.
SAllowthe chain to cut for you. Exert only
light downward pressure. If you force
thecut, damage to the bar, chain, or en-
ginec an result.
SRelease the throttle trigger as soon as
the cut is completed, allowing the en-
gine to idle. If you run the saw at full
throttlewithout a cutting load, unneces-
sary wear can occur to the chain, bar,
and engine. It is recommended that
the engine not be operatedfor lon-
ger than 30 seconds at full throttle.
SToavoid losing cont rol when cut is com-
plete, do not put pressure on saw at end
of cut.
SStop the engine before setting the saw
down after cutting.
TREE FELLINGTECHNIQUES
WARNING: C heck for broken or dead
branches which can fall while cutti ng causing
serious injury. Do not cut near buildings or
electrical wires if you do not know the dir ection
oftr ee fall, nor cut at night since you will not be
aleto see w ell, 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 be notified immediately.
SCarefullyplan your sawing operation in ad-
vance.
SClearthe work area. You need a c lear area
allaround the tree so you can have secure
footing.
SThe chain saw operator should keep on
the uphill side of the terrain as the tree is
likelyto roll or slide downhill after it is felled.
SStudy the natural conditions that can cause
the tree to fall in a particular direction.
