CHAIN BRAKE
WARNING: If the brak e bandis
worn too thin it may break when the chain
brakeis triggered. With a brok en brake band,
the chain brake will not stop the chain. The
chainbrake should be replac ed by an autho-
rizedserv ice dealer if any part is worn to less
than 0.020″(0.5 mm) thick. Repairson a
chain brake should be made by an autho-
rized service dealer. Take your unit to the
place of purchase if purchased from a ser-
vicing dealer, or to the nearest authorized
master service dealer.
SThis saw is equipped with a chain brake.
Thebr ake is designed to stop the chain if
kickbackoccurs.
SThe inertia--activated chain brake is
activatedif the front hand guard is pushed
forward, either manually (by hand) or
automatically (by sudden movement).
SIf the brake is already activated, it is
disengaged by 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.

WARNING: When performing the
following procedure, the engine must be
turned off.
Grip the re ar 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
grip on the front handle and use the weight of
thesaw to let the tip of the guide bar fall forw ard
andc ontact the stump. Whenthe tip of the bar
hits the stump, the brake should activate .
OPERATINGTIPS
SCheck chain tension before first use, af ter
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. Even a
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 forc e
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.
SToavoidlosing control w hen 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: Chec k for broken or
dead branches which can fall while cutting
causing serious injury. Do not cut near build-
ings or electrical wires if you do not know the
direction of tree fall, nor cut at night since you
will not be ale to see well, nor during bad
weather such as rain, snow, or s trong winds,
etc. If the tree makes contac tw ith any utility
line, the utility company should be notified im-
mediately.
SCarefullyplan your sawing operation in ad-
vance.
SClear the work area. You need a clear area
all around the tree so you can hav e 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.
