SPECIFIC SAFETY INSTRUCTIONS
WARNING! TWO HANDED OPERATION REQUIRED
This machine requires the use of two hands to ensure safe
operation and should not be used when working from ladders
andstepladders.
If the machine is to be used when working at height a suitable,
stable platform or scaffold tower with hand rails and kick boards
shouldbeused.
WARNING!
SomewoodandwoodtypeproductsespeciallyMDF(Medium
DensityFibreboard)canproducedustthatcanbehazardousto
yourhealth.Werecommendtheuseofanapprovedfacemask
with replaceable filters when using this machine in addition to
usingthedustextractionfacility.
DANGER
a) Keephandsawayfromcuttingareaand blade.Keep your
secondhandonauxiliaryhandle,ormotorhousing.Ifboth
handsareholdingthesaw,theycannotbecutbytheblade.
b) Donotreachunderneaththeworkpiece.Theguardcannot
protectyoufromthebladebelowtheworkpiece.
c) Adjustthecutting depthto thethicknessof theworkpiece.
Less than a full tooth of the blade teeth should be visible
belowtheworkpiece.
d) Neverholdthepiecebeingcutinyourhandsoracrossyour
leg.Securetheworkpiecetoastableplatform.Itisimportant
to support the work properly to minimize body exposure,
bladebinding,orlossofcontrol.
e) Hold the power tool by insulated gripping surfaces when
performing an operation where the cutting tool may contact
hiddenwiringoritsowncord.Contactwitha“live”wirewill
also make exposed metal parts of the power tool “live” and
shocktheoperator.
f) Whenripping,alwaysusearipfenceorstraightedgeguide.
This improves the accuracy of cut and reduces the chance of
thebladebinding.
g) Always use blades with correct size and shape (diamond
versusround)ofarbourholes.Bladesthatdonotmatchthe
mounting hardware of the saw will run eccentrically, causing
lossofcontrol.
h) Neverusedamagedorincorrectbladewashersorbolt.The
blade washers and bolt were specially designed for your
saw,foroptimumperformanceandsafetyofoperation.
CAUSES AND OPERATOR PREVENTION OF
KICKBACK
• Kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to lift up
andoutoftheworkpiecetowardtheoperator.
• Whenthebladeispinchedorboundtightlybythekerfclosing
down, the blade stalls and the motor reaction drives the unit
rapidlybacktowardtheoperator.
• Ifthe blade becomes twisted or misalignedin thecut,the
teeth at the back edge of the blade can dig into the top
surface of the wood causing the blade to climb out of the kerf
andjumpbacktowardoperator.
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautionsasgivenbelow.
a) Maintainafirmgripwithbothhandsonthesawandposition
your arms to resist kickback forces. Position yourbody to
eithersideoftheblade,butnotinlinewiththeblade.Kickback
could cause the saw to jump backwards, but kickback forces
can be controlled by the operator, if proper precautions are
taken.
b) When blade is binding, or when interrupting a cut for any
reason, release the trigger and hold the saw motionless in
thematerialuntilthebladecomestoacompletestop.Never
attempt to remove the saw from the work or pull the saw
backwardwhilethebladeisinmotionorkickbackmayoccur.
Investigate and take corrective actions to eliminate the cause
ofbladebinding.
c) Whenrestartingasawintheworkpiece,centrethesawblade
in the kerf and check that the saw teeth are not engaged into
thematerial.ifsawbladeisbinding,itmaywalkuporkick
backfromtheworkpieceasthesawisrestarted.
d) Supportlargepanelstominimisetheriskofbladepinching
and kickback. Large panels tend to sag under their own
weight.Supportsmustbeplacedunder the panel on both
sides,nearthelineofcutandneartheedgeofthepanel.
e) Do not use dull or damaged blades. Unsharpened or
improperly set blades produce a narrow kerf causing
excessivefriction,bladebindingandkickback.
f) Bladedepthandbeveladjustinglockingleversmustbetight
andsecurebeforemakingacut.Ifbladeadjustmentshifts
whilecutting,itmaycausebindingandkickback.
g) Useextracautionwhenmakinga“plungecut”intoexisting
walls or other blind areas. The protruding blade may cut
objectsthatcancausekickback.
SAFETY INSTRUCTIONS REGARDING LOWER
GUARD
a) Checklowerguardforproperclosingbeforeeachuse.Do
not operate the saw if the lower guard does not move freely
andcloseinstantly.Neverclamportiethelowerguardinthe
openposition.Ifthesawisaccidentallydropped,lowerguard
may be bent. Raise the lower guard with the blade guard
lever and make sure it moves freely and does not touch the
bladeoranyotherpart,inallanglesanddepthsofcut.
b) Checktheoperationofthelowerguardspring.Iftheguard
and the spring are not operating properly, they must be
serviced before use. Lower guard may operate sluggishly
due to damaged parts, gummy deposits, or a build-up of
debris.
c) Lowerguardshould beretractedmanually onlyfor special
cuts such as “plunge cuts” and “compound cuts”. Raise
lowerguardbybladeguardlever.Assoonasbladeenters
thematerial,thelowerguardmustbereleased.Forallother
sawingtasks,thelowerguardshouldoperateautomatically.
d) Always observe that the lower guard is covering the
blade before placing the saw down on bench or floor.An
