Scheppach HS105 Traduction Des Instructions D'origine page 34

Guiding the workpiece with the rip fence and the
mitre gauge at the same time increases the likeli-
hood 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 damaged push stick may break causing your
hand to slip into the saw blade.
g) Do not perform any operation "freehand".
Always use either the rip fence or the mitre
gauge to position and guide the workpiece.
"Freehand" means using your hands to sup-
port 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 binding 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 be-
fore 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 information
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 operating procedures
or conditions. And can be avoided by taking proper pre-
cautions 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 veloci-
ty 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 contact with the saw blade may occur
or kickback may drag your fingers into the saw
blade.
c) Never hold and press the workpiece that is be-
ing cut off against the rotating saw blade.
Pressing the workpiece being cut off against the
saw blade will create a binding condition and kick-
back.
d) Align the fence to be parallel with the saw
blade.
A misaligned fence will pinch the workpiece
against the saw blade and create kickback.
e) Use a featherboard to guide the workpiece
against the table and fence when making non-
through cuts such as rabbeting, dadoing or
resawing cuts.
A featherboard helps to control the workpiece in
the event of a kickback.
f) Use extra caution when making a cut into blind
areas of assembled workpieces.
The protruding saw blade may cut objects that can
cause kickback.
