OPERATION
GENERAL OPERATION TIPS
• Cut wood only.Do not cut metal; plastics;masonry;non-
wood buildingmaterials; etc.
• Stop the saw ifthe chain strikes a foreignobject.Inspect
the saw and repair or replace parts as necessary.
• Keep the chain out of dirt and sand. Even a small
amount of dirtwill quicklydull a chain and thus increase
the possibilityof kickback.
To get the "feel" of using your saw before you begin a
major sawing operation, practice cutting a few small logs
using the followingtechnique:
• Accelerate engine to full throttle by squeezing the throt-
tle triggerbefore entering cut.
• Never cutwith engine at partial speeds.
• Begin cutting withthe saw chassis against the log.
• Keep engine at fullthrottle duringcutting procedure.
• Allow the chain tocut for you;exert only lightdownward
pressure. If you force the cut, damage to the bar, chain,
or engine can result.
• Release the throttle trigger as soon as the cut is com-
pleted, allowing the engine to idle. If you run the unit at
full throttle without cutting,unnecessary wear can occur
tothe chain, bar, and engine.
• To avoid losingcontrol when completingthe cut, do not
put pressure on the saw dudngthe end ofthe cut.
• Stop engine beforesetting unitdown after operation.
OPERATION SAFETY
WARNING
IF SAW BECOMES PINCHED OR HUNG IN
A 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 INTOTHE
CUT UNTIL THE SAW CAN BE REMOVED
EASILY. RESTART THE SAW AND CARE-
FULLY REENTER THE CUT. TO AVOID
KICKBACK AND CHAIN DAMAGE, DO NOT
USE A METAL WEDGE. DO NOT A'I'rEMPT
TO RESTART YOUR SAW WHEN IT IS
PINCHED OR HUNG IN A LOG.
KICKBACK CAN OCCUR WHEN THE MOV-
ING CHAIN CONTACTS AN OBJECT AT
THE UPPER PORTION OF THE TIP OF THE
GUIDE BAR OR WHEN THE WOOD CLOS-
ES IN AND PINCHES THE SAW CHAIN IN
THE CUT. CONTACT ATTHE UPPER POR-
TION OFTHETIP OFTHE 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
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-Kickback and Pull-In occur when the chain is sud-
denly stopped by being"pinched,caught, or by contacting
a foreign object in the wood.This sudden stopping of the
chain results in a reversal of the chain force used to cut
wood and causes the saw to move in the opposite direc-
tion of the chain rotation. Pinch-Kickback drives the saw
straight back toward the operator. Pull-In pulls the saw
away from the operator. Either reaction can result in loss
of controland possiblyserious injury.
TO AVOID PINCH-KICKBACK:
• Be extremely aware of situations or obstructions that
can cause material to pinchthe top of or otherwise stop
the chain.
• Do not cut more than one logat a time.
• Do not twist the saw as the bar is withdrawn from an
under-cut when bucking.
TO AVOID PULL-IN
• Always begin cutting with the engine at full throttle and
the saw housingagainst wood.
• Use wedges made of plasticor wood, (never of metal)
to hold the cut open.
