Cordless circular saw safety
warnings
Cutting procedures
1.
DANGER: Keep hands away from cutting area
and the blade. Keep your second hand on auxil-
iary 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 off-centre, causing loss of control.
8. Never use damaged or incorrect blade wash-
ers 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 reac-
tion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controlled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 correc-
tive 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work-
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.
►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.

12 ENGLISH
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.
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, especially 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accuracy,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
handle and as soon as the blade enters the mate-
rial, the lower guard must be released. For all other
sawing,thelowerguardshouldoperateautomatically.
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
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 off.
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 off
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 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 specied in the man-
ual.Useofanincorrectlysizedblademayaffect
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 poten-
tial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.
