Work area safety
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
whichmayignitethedustorfumes.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
youtolosecontrol.
Electrical safety
1. Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodiedplugsandmatchingoutletswill
reduce risk of electric shock.
2. Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tricshockifyourbodyisearthedorgrounded.
3. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
4. Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
5. When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.
6. If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
7.
Power tools can produce electromagnetic elds
(EMF) that are not harmful to the user. However,
users of pacemakers and other similar medical devices
should contact the maker of their device and/or doctor
for advice before operating this power tool.
Personal safety
1. Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired or
under the inuence of drugs, alcohol or med-
ication. A moment of inattention while operating

8. Do not let familiarity gained from frequent use
of tools allow you to become complacent and
ignore tool safety principles. A careless action
cancausesevereinjurywithinafractionofa
second.
9. Always wear protective goggles to protect
your eyes from injury when using power tools.
The goggles must comply with ANSI Z87.1 in
the USA, EN 166 in Europe, or AS/NZS 1336
in Australia/New Zealand. In Australia/New
Zealand, it is legally required to wear a face
shield to protect your face, too.
It is an employer's responsibility to enforce
the use of appropriate safety protective equip-
ments by the tool operators and by other per-
sons in the immediate working area.
Power tool use and care
1. Do not force the power tool. Use the correct
power tool for your application. The correct

Cutting procedures
1. D
ANGER: Keep hands away from cutting area
and the blade. Keep your second hand on auxiliary
handle, or motor housing. If both hands are holding
thesaw,theycannotbecutbytheblade.
2. Do not reach underneath the workpiece. The
guardcannotprotectyoufromthebladebelowthe
workpiece.

5ENGLISH
3. 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.
4. Never hold the workpiece in your hands or
across your leg while cutting. Secure the
workpiece to a stable platform. It is important to
supporttheworkproperlytominimisebodyexpo-
sure, blade binding, or loss of control.
5. Hold the power tool by insulated gripping
surfaces, when performing an operation where
the cutting tool may contact hidden wiring.
Contact with a “live” wire will also make exposed
metal parts of the power tool “live” and could give
the operator an electric shock.
6. When ripping, always use a rip fence or
straight edge guide.Thisimprovestheaccuracy
of cut and reduces the chance of blade binding.
7. Always use blades with correct size and shape
(diamond versus round) of arbour holes.
Blades that do not match the mounting hardware
ofthesawwillruno-centre,causinglossof
control.
8. Never use damaged or incorrect blade wash-
ers or bolt. The blade washers and bolt were
speciallydesignedforyoursaw,foroptimum
performanceandsafetyofoperation.
Kickback causes and related warnings
— kickback is a sudden reaction to a pinched,
jammedormisalignedsawblade,causingan
uncontrolled saw to lift up and out of the workpiece
toward the operator;
— whenthebladeispinchedorjammedtightlybythe
kerf closing down, the blade stalls and the motor
reactiondrivestheunitrapidlybacktowardthe
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
toclimboutofthekerfandjumpbacktowardthe
operator.
Kickbackistheresultofsawmisuseand/orincorrect
operating procedures or conditions and can be avoided
bytakingproperprecautionsasgivenbelow.
1. Maintain a rm 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
couldcausethesawtojumpbackwards,but
kickbackforcescanbecontrolledbytheoperator,
if proper precautions are taken.
2. 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.
3. When restarting a saw in the workpiece, centre
the saw blade in the kerf so that the saw teeth
are not engaged into the material. If a saw blade
binds,itmaywalkuporkickbackfromthework-
piece as the saw is restarted.
4. 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.
5. Do not use dull or damaged blades.
Unsharpenedorimproperlysetbladesproduce
narrow kerf causing excessive friction, blade
binding and kickback.
6. Blade depth and bevel adjusting locking levers
must be tight and secure before making the
cut.Ifbladeadjustmentshiftswhilecutting,itmay
cause binding and kickback.
7. Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
maycutobjectsthatcancausekickback.
8. ALWAYS hold the tool rmly with both hands.
NEVER place your hand, leg or any part of your
body under the tool base or behind the saw,
especially when making cross-cuts. If kickback
occurs,thesawcouldeasilyjumpbackwardsover

6ENGLISH
9. Never force the saw. Push the saw forward at a
speed so that the blade cuts without slowing.
Forcing the saw can cause uneven cuts, loss of
accuracy,andpossiblekickback.
Lower guard function
1. Check the 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
into the open position.Ifthesawisaccidentally
dropped,thelowerguardmaybebent.Raisethe
lower guard with the retracting handle and make
sureitmovesfreelyanddoesnottouchtheblade
oranyotherpart,inallanglesanddepthsofcut.
2. Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use.
Lowerguardmayoperatesluggishlydueto
damagedparts,gummydeposits,orabuild-upof
debris.
3. The lower guard may be retracted manually
only for special cuts such as “plunge cuts”
and “compound cuts”. Raise the lower guard
by the retracting handle and as soon as the
blade enters the material, the lower guard
must be released. For all other sawing, the lower
guardshouldoperateautomatically.
4. Always observe that the lower guard is cover-
ing the blade before placing the saw down on
bench or oor. An unprotected, coasting blade
will cause the saw to walk backwards, cutting
whatever is in its path. Be aware of the time it
takes for the blade to stop after switch is released.
5. To check lower guard, open lower guard by
hand, then release and watch guard closure.
Also check to see that retracting handle does
not touch tool housing. Leaving blade exposed
is VERY DANGEROUS and can lead to serious
personalinjury.
Additional safety warnings
1. Use extra caution when cutting damp wood,
pressure treated lumber, or wood containing
knots. Maintain smooth advancement of tool with-
out decrease in blade speed to avoid overheating
the blade tips.
2. Do not attempt to remove cut material when
blade is moving. Wait until blade stops before
grasping cut material.Bladescoastafterturno.
3. Avoid cutting nails. Inspect for and remove all
nails from lumber before cutting.
4. Place the wider portion of the saw base on
that part of the workpiece which is solidly
supported, not on the section that will fall o
when the cut is made. If the workpiece is short
or small, clamp it down. DO NOT TRY TO HOLD
SHORT PIECES BY HAND!
5. Before setting the tool down after completing a
cut, be sure that the guard has closed and the
blade has come to a complete stop.
6. Never attempt to saw with the circular saw
held upside down in a vise. This is extremely
dangerous and can lead to serious accidents.
7.
Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
8. Do not stop the blades by lateral pressure on
the saw blade.
9. Do not use any abrasive wheels.
10. Only use the saw blade with the diameter that
is marked on the tool or specied in the man-
ual.Useofanincorrectlysizedblademayaect

11. Keep blade sharp and clean. Gum and wood
pitch hardened on blades slows saw and
increasespotentialforkickback.Keepbladeclean
byrstremovingitfromtool,thencleaningitwith
gum and pitch remover, hot water or kerosene.
Never use gasoline.
12. Wear a dust mask and hearing protection when
use the tool.
13. Always use the saw blade intended for cutting
the material that you are going to cut.
14. Only use the saw blades that are marked with
a speed equal or higher than the speed marked
on the tool.
15. (For European countries only)
Always use the blade which conforms to
EN847-1.
