2 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.
Caution!
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.
) 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unprotected,coastingbladewillcausethesawto 
 walkbackward,cuttingwhateverisinitspath.
Warning!
Be aware of the time it takes for the blade to stop
after the switch is released.
