Cordless circular saw safety
warnings
Cutting procedures
1. DANGER:
Keep hands away from cutting area
and the 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.
2. Do not reach underneath the workpiece. The guard
cannotprotectyoufromthebladebelowtheworkpiece.
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
supporttheworkproperlytominimisebodyexpo-
sure, blade binding, or loss of control.
►Fig.1
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.Thisimprovestheaccuracy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 of the saw will run
o󰀨-centre,causinglossofcontrol.
8. 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.
Kickback causes and related warnings
— kickbackisasuddenreactiontoapinched,jammed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jammed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theoperator.
Kickbackistheresultofsawmisuseand/orincorrect
operating procedures or conditions and can be avoided
bytakingproperprecautionsasgivenbelow.
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couldcausethe
sawtojumpbackwards,butkickbackforcescanbecon-
trolledbytheoperator,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,itmay
walk up or kickback from the workpiece 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.
►Fig.2
►Fig.3
5. Do not use dull or damaged blades.
Unsharpenedorimproperlysetbladesproduce
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.
Ifbladeadjustmentshiftswhilecutting,itmaycause
binding and kickback.

13 ENGLISH
7. Use extra caution when sawing into existing walls
or other blind areas.Theprotrudingblademaycut
objectsthatcancausekickback.
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, espe-
cially when making cross-cuts. If kickback occurs,
thesawcouldeasilyjumpbackwardsoveryourhand,
leadingtoseriouspersonalinjury.
►Fig.4
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 accu-
racy,andpossiblekickback.
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.
Ifthesawisaccidentallydropped,thelowerguardmay
be bent. Raise the lower guard with the retracting handle
andmakesureitmovesfreelyanddoesnottouchthe
bladeoranyotherpart,inallanglesanddepthsofcut.
2. Check the operation of the lower guard spring. If
the guard and the spring are not operating prop-
erly, they must be serviced before use. Lower guard
mayoperatesluggishlyduetodamagedparts,gummy
deposits, or a build-up of 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 han-
dle and as soon as the blade enters the material, the
lower guard must be released. For all other sawing,
thelowerguardshouldoperateautomatically.
4.
Always observe that the lower guard is covering 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 hous-
ing. Leaving blade exposed is VERY DANGEROUS
andcanleadtoseriouspersonalinjury.
Additional safety warnings
1. Use extra caution when cutting damp wood, pres-
sure treated lumber, or wood containing knots.
Maintain smooth advancement of tool without 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.Bladescoastafterturno󰀨.
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!
►Fig.5
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.
►Fig.6
7. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion 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 specied in the man-
ual.Useofanincorrectlysizedblademaya󰀨ect
the proper guarding of the blade or guard opera-
tionwhichcouldresultinseriouspersonalinjury.
11. Keep blade sharp and clean. Gum and wood
pitch hardened on blades slows saw and
increasespotentialforkickback.Keepbladeclean
byrstremovingitfromtool,thencleaningitwith
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.
