Causes of and ways to avoid recoil:
•
A recoil is the sudden reaction resulting from
a caught, jammed or incorrectly aligned saw
blade which may result in the saw leaping out
of the workpiece out of control and towards
the operator.
•
If the saw blade becomes caught or jammed
in closing saw gap, it will block and the power
of the motor will cause the saw to leap back-
wards towards the operator.
•
If the saw blade is twisted or incorrectly alig-
ned in the cut, the teeth in the rear saw blade
edge may become caught in the surface of
the workpiece, which results in the saw blade
leaping out of the saw gap and the saw lea-
ping towards the operator.
A recoil is the result of incorrect or wrong use of
the saw. It can be prevented by suitable precau-
tions, as described below.
a) Hold the saw
fi
rmly in both hands and
hold your arms in a position in which you
can withstand the recoil forces. Always
hold the saw blade to one side. Never
hold the saw blade in a straight line with
your body.
In the event of a recoil the circular
saw may leap backwards, but the user can
still overcome the recoil forces if he has taken
suitable precautions.
b) If the saw blade jams or the sawing ope-
rating is interrupted for another reason,
release the ON/OFF switch and hold the
saw steady in the workpiece until the saw
blade has reached a complete standstill.
Never attempt to take the saw out of the
workpiece or to pull it backwards whilst
the saw blade is moving or there is a
possibility of a recoil.
Find the reason for
the blade jamming and rectify it by suitable
means.
c) If you wish to restart a saw that is already
in the workpiece, center the saw blade
in the saw gap and check that the saw’s
teeth are not caught in the workpiece.
If
the saw blade is jammed it may move out of
the workpiece or cause a recoil when the saw
is restarted.
d) Support large panels to reduce the risk of
a recoil by a jammed saw blade.
Large pa-
nels may sag under their own weight. Panels
must be supported on both sides both near
the saw gap and also at the edge.
e) Do not use blunt or damaged saw blades.
Saw blades with blunt or incorrectly aligned
teeth will create increased friction due to the
saw gap being too small. In addition the saw
blade may also jam and cause recoil.
f) Secure the cutting depth and cutting ang-
le settings before starting to saw.
If the
settings change as you are sawing, the saw
blade may jam and cause recoil.
g) Be particularly careful when carrying out
a “plunge cut” in a concealed area such
as an existing wall.
The plunge-cutting saw
blade may block when sawing into concealed
objects and thus cause recoil.
h)
Do not use grinding wheels!
i)
The diameters of the saw blades used must
correspond to the diameters speci
fi
ed on the
hand-held circular saw blade!
j)
Use only recommended saw blades!
Safety instructions for saws with a swing
guard hood
a) Check that the bottom safety hood closes
perfectly before using the appliance. Do
not use the saw if the bottom safety hood
does not move freely and does not close
immediately. Never clamp or tie the bot-
tom guard hood in open position.
If you
drop the saw by accident the bottom guard
hood may become bent. Open the safety
hood with the lever and ensure that it moves
freely and will not come into contact with the
saw blade or other parts regardless of the
cutting angle and depth.
b) Check the function of the spring on the
bottom safety hood. Have the appliance
serviced before you use it if the bottom
safety hood and spring are not in perfect
working order.
Damaged parts, sticky depo-
sits or accumulations of chips will result in the
bottom guard hood working with a delay.
c) Open the bottom safety hood by hand
only for special cuts, such as “immersion
and angle cuts”. Open the bottom safety
hood using the lever and release the lever
again as soon as the saw blade has en-
gaged in the workpiece.
The bottom safety
hood must operate automatically for all other
sawing work.
