If the workpiece or blade becomes jammed, turn the
metal chopsaw off. Wait for all moving parts to stop and
disconnect the plug from the power source and/or
remove the battery pack. Then work to free the jammed
material. Continued sawing with a jammed workpiece
could cause loss of control or damage to the metal
chopsaw.
After finishing the cut, release the switch, hold the saw
head down and wait for the blade to stop before remov-
ing the cut-off piece. Reaching with your hand near the
coasting blade is dangerous.
Hold the handle firmly when making an incomplete cut
or when releasing the switch before the saw head is
completely in the down position. The braking action of
the saw may cause the saw head to be suddenly pulled
downward, causing a risk of injury.
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 cut
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 metal, causing the blade to climb out
of the cut 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.
Maintain a firm grip on saw handle 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.
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 remove the saw blade from the work piece
while 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, center the saw
blade in the cut and check that saw teeth are not
engaged into the material. If saw blade is binding, it may
walk up or kickback from the workpiece as the saw is
restarted.
Support long material lengths to minimize the risk of
blade pinching and kickback. Long length materials
tend to sag under their own weight. Supports must be
placed under the material on both sides near the line of
cut and near the edge of the material.
Do not use dull or damaged blades. Unsharpened or
improperly mounted blades produce narrow cuts caus-
ing excessive friction, blade binding and kickback.
Blade depth and bevel adjusting locking levers must be
tight and secure before making cut. If blade adjustment
shifts while cutting, it may cause binding and kickback.
Do not use accessories which are not specifically
designed and recommended by the tool manufacturer.
Just because the accessory can be attached to your
power tool, it does not assure safe operation.
Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. Where appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments. The eye
protection must be capable of stopping flying debris
generated by various operations. The dust mask or res-
pirator must be capable of filtrating particles generated
by your operation. Prolonged exposure to high inten-
sity noise may cause hearing loss.
Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal pro-
tective equipment. Fragments of workpiece or of a bro-
ken accessory may fly away and cause injury beyond
immediate area of operation.
Regularly clean the power tool's air vents. The motor's
fan will draw the dust inside the housing and excessive
accumulation of powdered metal may cause electrical
hazards.
Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in elec-
trocution or shock.
Secure the work piece firmly. A work piece that is
gripped tightly in a clamping device or vice, is more
secure than if held by hand.
Before putting into operation, check the mains connec-
tion and the mains plug for damage.
Always operate the power tool with together with a
PRCD personal protection switch (*).Before beginning
to work, always check the proper functioning of the
PRCD personal protection switch (*) (see page 30).
Further safety warnings
Use ear protection during operation.
Use a stationary extraction system, blow out ventilation
slots frequently and connect a residual current device
(RCD) on the line side. When working metal under
extreme operating conditions, it is possible for conduc-
tive dust to settle in the interior of the power tool. The
total insulation of the power tool can be impaired.
Do not rivet or screw any name-plates or signs onto the
power tool. If the insulation is damaged, protection
against an electric shock will be ineffective.
Do not work with materials containing magnesium.
Danger of fire.
Do not work with CFRP (carbon-fiber-reinforced poly-
mer) and materials containing asbestos. These materi-
als are considered carcinogenic.
