• Stopthesaw ifthechainstdkes a foreignobject. Inspect
the saw and mpetr or replace parts as necessary.
• Keep the chain out of dirt and sand. Even a small
amountofdirtwillquicklydulla chainand thusincrease
thepossibilityof kickback.

OPERATION SAFETY - GENERAL
GENERALSAFETY
WARNING
IF SAW BECOMES PINCHED OR HUNG INA
LOG, DO NOT TRY TO FORCE IT OUT.YOU
CAN LOSE CONTROL OF THE SAW
RESULTING IN INJURY AND/OR DAMAGE
TO THE SAW. STOP THE SAW, DRIVE A
WEDGE OF PLASTIC OR WOOD INTO THE
CUT UNTIL THE SAW CAN BE REMOVED
EASILY. RESTART THE SAW AND
CAREFULLY REENTER THE CUT. TO
AVOID KICKBACK AND CHAIN DAMAGE,
DO NOT USE A METAL WEDGE. DO NOT
ATTEMPT TO RESTART YOUR SAW WHEN
IT IS PINCHED OR HUNG IN A LOG.
KICKBACK CAN OCCUR WHEN THE
MOVING CHAIN CONTACTS AN OBJECT
AT THE UPPER PORTION OF THE TIP OF
THE GUIDE BAR OR WHEN THE WOOD
CLOSES IN AND PINCHES THE SAW CHAIN
IN THE CUT. CONTACT AT THE UPPER
PORTION OF THE TIP OF THE GUIDE BAR
CAN CAUSE THE CHAIN TO DIG INTO THE
OBJECT AND STOP THE CHAIN FOR AN
INSTANT. THE RESULT IS A LIGHTNING
FAST, REVERSE REACTION WHICH KICKS
THE GUIDE BAR UP AND BACK TOWARD i
THE OPERATOR. IF THE SAW CHAIN IS!
PINCHED ALONG THE TOP OF THE GUIDE
BAR, THE GUIDE BAR CAN BE DRIVEN
RAPIDLY BACK TOWARD THE OPERATOR.
EITHER OF THESE REACTIONS CAN
CAUSE LOSS OF SAW CONTROL WHICH
CAN RESULT IN SERIOUS INJURY.
AVOID REACTIVE PINCH FORCES
Pinch-Kickbackand Pull-Inoccurwhenthechainissud-
denlystoppedby being pinched,caught, or bycontact-
inga foreignobjectinthewood. Thissuddenstoppingof
the chain resultsina reversalofthe chainforce usedto
cut wood and causes the saw to move inthe opposite
direction of the chain rotation. Pinch-Kickbackdrives
thesaw straightback towardtheoperator. Pult-lnpulls
thesaw away fromtheoperator. Eitherreactioncan re-
suitin lossofcontroland possiblyseriousinjury.
TO AVOID PINCH-KICKBACK:
• Be extremelyaware ofsituationsor obstructionsthat
can cause matedai to pinchthe top of or otherwise
stop the chain.
• Do not cut more than one logat a time.
• Do not twistthesaw as thebar iswithdrawnfroman
under-cutwhen bucking.
TO AVOID PULL-IN:
• Always begin cutting with the engine at full throttle
and the saw housingagainstwood.
• Use wedges made of plastic or wood, (never of
metal) tohold the cutopen.
