Safety Instructions For All Saws - Scheppach PL75 Originalbetriebsanleitung

g) Use power tools, accessories, and equipment ac-
cording to these instructions. Taking into account the
working conditions and the work being performed.
The use of power tools other than those intended for
the tool itself can lead to dangerous situations.
5) Service
a) Only let qualified service personnel repair your tool
and always use original replacement parts. This guar-
antees that the power tool remains safe to use.

6. Safety instructions for all saws

a) DANGER: Do not put your hands in the sawing area
or on the saw blade. Keep your second hand on the
extra handle of the motor housing. If both hands are
holding the saw, neither can be injured by the saw
blade.
One-handed operation is permitted only in conjunc-
tion with rail and anti-tilt.
b) Do not put your hands under the work piece. The pro-
tective cap cannot protect your hands from the blade
when they are under the work piece.
c) Adjust the cutting depth to the thickness of the work
piece. Less than one complete sawing tooth should
be visible under the work piece.
d) Never hold the work piece that is to be sawn in your
hand or over your leg. Make sure that the work piece
has a stable balance. It is important that the work
piece is held securely, in order to minimize the danger
of contact of a body part with the saw, loss of control
over the saw, or jamming of the blade.
e) Hold the equipment on the insulated handles, when
you undertake work in which the tool being used
could come into contact with hidden electrical wires,
or its own cable. Contact with a live power source
can electrify the metal parts of the tool and lead to
an electrical shock.
f) When making a long cut, always use a stop chock
or a straightedge. This improves the accuracy of the
cut and reduces the chance that the saw blade jams.
g) Always use the correct size of saw blades and make
sure they have the right locating bore (e.g. Star
shaped or round). Saw blades that do not fit the as-
sembly of the saw do not run correctly and cause
loss of control.
h) Never use damaged or incorrect saw blade shims
or screws.
The saw blade shims and screws are designed es-
pecially for your saw, for optimal performance and
operating safety.
7. Additional safety instructions for all
saws
Causes and prevention of kickbacks:
• A kickback is a sudden reaction due to a caught,
jammed or incorrectly adjusted saw blade, which
leads to the saw rearing up in an uncontrolled man-
ner and moving out of the work piece towards the
operator.
• If a saw blade catches or jams in the sawing edge
that closes behind it, it is blocked and motor's drive
pushes the saw back in the direction of the operator.
• If the saw blade twists in the saw groove or is in-
correctly positioned, the teeth at the rear side of
the saw blade edge catch in the surface of the work
piece. The saw then moves out of the saw groove and
springs back in the direction of the operator.
• A kickback results from an incorrect or faulty use of
the saw. It can be prevented, as will be described in
the following, by appropriate cautionary measures.
a) Hold onto the saw with both hands and position your
arms so that they can absorb any energy from a kick-
back. Always keep to the side of the saw blade, and
never bring it into line with your body. In the case of
a kickback, the circular saw can jump backwards, but
with adequate caution the operator can deal with the
energy of the kickback.
b) If the saw blade jams or you want to interrupt your
work, then turn the saw off and keep the work piece
still until the saw blade comes to a full stop. Never
try to remove the saw from the work piece or pull it
out when the saw blade is moving since then a kick-
back can occur. Find out the cause of the jam and
remove it.
c) If you want to start up a saw that is in the work piece,
centre the saw blade in the sawed groove and check
that the saw blade teeth are not caught in the work
piece. If the saw blade is jammed, it can jump out
of the work piece or cause a kick back when it is
started up.
d) Support larger work pieces in order to reduce the risk
of a kick back due to a saw blade jam. The weight
of larger work pieces can cause them to bend. Large
pieces must be supported on both sides, both near
the sawing slot as well as on the edges.
e) Do not use dull or damaged saw blades. Saw blades
with dull or misaligned teeth increase the friction, in
the sawing slot, cause saw blade jams and kickbacks.
f) Before you start sawing, tighten the adjustments for
the cut depth and angles. If you change settings while
sawing, the saw blade can jam and a kickback is the
result.
g) Be particularly careful when making "inserted cuts"
in walls that already exist or other areas where you
cannot see what is behind the surface. When the saw
blade is inserted into the wall it can be blocked by hid-
den objects and cause a kick back.
