Kickback - Causes And Corresponding Safety Instructions - Parkside PMTS 210 A1 Originalbetriebsanleitung

c) Immediately reattach the guarding system af-
ter completing an operation (such as rabbet-
ing, dadoing or resawing cuts) which requires
removal of the saw blade guard and/or riving
knife. The guard and riving knife help to reduce the risk
of injury.
d) Make sure the saw blade is not contacting the
guard, riving knife or the workpiece before the
switch is turned on. Inadvertent contact of these items
with the saw blade could cause a hazardous condition.
e) Adjust the riving knife as described in this in-
struction manual. Incorrect spacing, positioning
and alignment can make the riving knife inef-
fective in reducing the likelihood of kickback.
f) For the riving knife to work, they must be en-
gaged in the workpiece. The riving knife is ineffective
when cutting workpieces that are too short to be engaged
with the riving knife. Under these conditions a kickback
cannot be prevented by the riving knife.
g) Use the appropriate saw blade for the riving
knife. For the riving knife to function properly, the saw
blade diameter must match the appropriate riving knife
and the body of the saw blade must be thinner than the
thickness of the riving knife and the cutting width of the saw
blade must be wider than the thickness of the riving knife.
Cutting procedures warnings
a) m DANGER: Never place your fingers or hands
in the vicinity or in line with the saw blade. A
moment of inattention or a slip could direct your hand to-
wards the saw blade and result in serious personal injury.
b) Feed the workpiece into the saw blade or cut-
ter only against the direction of rotation. Feeding
the workpiece in the same direction that the saw blade is
rotating above the table may result in the workpiece, and
your hand, being pulled into the saw blade.
c) Never use the mitre gauge to feed the work-
piece when ripping and do not use the rip fence
as a length stop when cross cutting with the mi-
tre gauge. Guiding the workpiece with the rip fence and
the mitre gauge at the same time increases the likelihood of
saw blade binding and kickback.
d) When ripping, always apply the workpiece
feeding force between the fence and the saw
blade. Use a push stick when the distance be-
tween the fence and the saw blade is less than
150 mm, and use a push block when this dis-
tance is less than 50 mm. "Work helping" devices
will keep your hand at a safe distance from the saw blade.
e) Use only the push stick provided by the manu-
facturer or constructed in accordance with the
instructions. This push stick provides sufficient distance
of the hand from the saw blade.
f) Never use a damaged or cut push stick. A dam-
aged push stick may break causing your hand to slip into
the saw blade.

g) Do not perform any operation "freehand". Al-
ways use either the rip fence or the mitre gauge
to position and guide the workpiece. "Free-
hand" means using your hands to support or
guide the workpiece, in lieu of a rip fence or
mitre gauge. Freehand sawing leads to misalignment,
binding and kickback.
h) Never reach around or over a rotating saw
blade. Reaching for a workpiece may lead to accidental
contact with the moving saw blade.
i) Provide auxiliary workpiece support to the
rear and/or sides of the saw table for long
and/or wide workpieces to keep them level. A
long and/or wide workpiece has a tendency to pivot on
the table's edge, causing loss of control, saw blade bind-
ing and kickback.
j) Feed workpiece at an even pace. Do not bend
or twist the workpiece. If jamming occurs, turn
the tool off immediately, unplug the tool then
clear the jam. Jamming the saw blade by the workpiece
can cause kickback or stall the motor.
k) Do not remove pieces of cut-off material while
the saw is running. The material may become trapped
between the fence or inside the saw blade guard and the
saw blade pulling your fingers into the saw blade. Turn the
saw off and wait until the saw blade stops before removing
material.
l) Use an auxiliary fence in contact with the table
top when ripping workpieces less than 2 mm
thick. A thin workpiece may wedge under the rip fence
and create a kickback.
Kickback - causes and corresponding safety in-
structions
Kickback is a sudden reaction of the workpiece due to a
pinched, jammed saw blade or misaligned line of cut in the
workpiece with respect to the saw blade or when a part of the
workpiece binds between the saw blade and the rip fence or
other fixed object.
Most frequently during kickback, the workpiece is lifted from
the table by the rear portion of the saw blade and is propelled
towards the operator.
Kickback is the result of saw misuse and/or incorrect operat-
ing procedures or conditions. And can be avoided by taking
proper precautions as given below.
a) Never stand directly in line with the saw blade.
Always position your body on the same side of
the saw blade as the fence. Kickback may propel
the workpiece at high velocity towards anyone standing in
front and in line with the saw blade.
b) Never reach over or in back of the saw blade to
pull or to support the workpiece. Accidental con-
tact with the saw blade may occur or kickback may drag
your fingers into the saw blade.
