unpredictable behaviour resulting in fire, explosion or
risk of injury.
Do not expose a battery pack or tool to fire or ex-
u
cessive temperature. Exposure to fire or temperature
above 130°C may cause explosion.
Follow all charging instructions and do not charge
u
the battery pack or tool outside the temperature
range specified in the instructions. Charging improp-
erly or at temperatures outside the specified range may
damage the battery and increase the risk of fire.
Service
Have your power tool serviced by a qualified repair
u
person using only identical replacement parts. This
will ensure that the safety of the power tool is main-
tained.
Never service damaged battery packs. Service of
u
battery packs should only be performed by the manu-
facturer or authorized service providers.
Safety instructions for circular
saws
Cutting procedures
DANGER: Keep hands away from cutting area
u
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.
Do not reach underneath the workpiece. The guard
u
cannot protect you from the blade below the workpiece.
Adjust the cutting depth to the thickness of the
u
workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
Never hold the workpiece in your hands or across
u
your leg while cutting. Secure the workpiece to a
stable platform. It is important to support the work
properly to minimise body exposure, blade binding, or
loss of control.
Hold the power tool by insulated gripping surfaces,
u
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.
When ripping always use a rip fence or straight edge
u
guide. This improves the accuracy of cut and reduces
the chance of blade binding.
Always use blades with correct size and shape (dia-
u
mond versus round) of arbour holes. Blades that do
not match the mounting hardware of the saw will run off-
centre, causing loss of control.
Never use damaged or incorrect blade washers or
u
bolt. The blade washers and bolt were specially de-
signed 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 sur-
face 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 oper-
ating procedures or conditions and can be avoided by tak-
ing proper precautions as given below.
Maintain a firm grip with both hands on the saw and
u
position your arms to resist kickback forces. Posi-
tion 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.
When blade is binding, or when interrupting a cut for
u
any reason, release the trigger and hold the saw mo-
tionless in the material until the blade comes to a
complete stop. Never attempt to remove the saw
1 609 92A 65W | (31.03.2021)
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.
When restarting a saw in the workpiece, centre the
u
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 re-
started.
Support large panels to minimise the risk of blade
u
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.
Do not use dull or damaged blades. Unsharpened or
u
improperly set blades produce narrow kerf causing ex-
cessive friction, blade binding and kickback.
Blade depth and bevel adjusting locking levers must
u
be tight and secure before making the cut. If blade
adjustment shifts while cutting, it may cause binding
and kickback.
Use extra caution when sawing into existing walls or
u
other blind areas. The protruding blade may cut ob-
jects that can cause kickback.
Lower guard function
Check the lower guard for proper closing before
u
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.
Check the operation of the lower guard spring. If the
u
guard and the spring are not operating properly,
they must be serviced before use. Lower guard may
operate sluggishly due to damaged parts, gummy de-
posits, or a build-up of debris.
The lower guard may be retracted manually only for
u
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 guard should operate automatically.
Always observe that the lower guard is covering the
u
blade before placing the saw down on bench or
floor.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.
Additional safety warnings
Do not allow the chip ejector to come into contact
u
with your hands. You may be injured by rotating parts.
Do not use the saw above the level of your head. Do-
u
ing so will mean you have inadequate control of the
power tool.
Use suitable detectors to determine if there are hid-
u
den supply lines or contact the local utility company
for assistance. Contact with electric cables can cause
fire and electric shock. Damaging gas lines can lead to
explosion. Breaking water pipes causes property dam-
age.
Hold the power tool firmly with both hands and make
u
sure you have a stable footing. The power tool can be
more securely guided with both hands.
Do not operate the power tool when stationary . It is
u
not suitable for operation with a saw table.
When performing plunge cuts which are not right-
u
angled, secure the guide plate of the saw so that it
will not shift sideways.In the event of a sideways shift,
the saw blade may become jammed, which could lead to
kickback.
Secure the workpiece. A workpiece clamped with
u
clamping devices or in a vice is held more secure than
by hand.
Always wait until the power tool has come to a com-
u
plete stop before placing it down. The application tool
can jam and cause you to lose control of the power tool.
Do not use HSS saw blades. Such saw blades can eas-
u
ily break.
Do not saw any ferrous metals. Hot chips may ignite
u
the dust extractor.
Wear a dust mask.
u
In case of damage and improper use of the battery,
u
vapours may be emitted. The battery can set alight
or explode. Ensure the area is well ventilated and seek
medical attention should you experience any adverse ef-
fects. The vapours may irritate the respiratory system.
Do not open the battery. There is a risk of short-circuit-
u
ing.
The battery can be damaged by pointed objects such
u
as nails or screwdrivers or by force applied extern-
ally. An internal short circuit may occur, causing the
battery to burn, smoke, explode or overheat.
Only use the battery with products from the manu-
u
facturer. This is the only way in which you can protect
the battery against dangerous overload.
Protect the battery against heat, e.g.
against continuous intense sunlight, fire,
dirt, water and moisture. There is a risk of
explosion and short-circuiting.

Intended use

The power tool is intended for making straight cuts in wood
with and against the grain and mitre cuts in wood while
resting firmly against the workpiece.
