Kickback and related warnings:
Kickback is a sudden reaction to a pinched or snagged rotat-
ing wheel, backing pad, brush or any other accessory. Pinch-
ing or snagging causes rapid stalling of the rotating access-
ory which in turn causes the uncontrolled power tool to be
forced in the direction opposite of the accessory's rotation
at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by
the workpiece, the edge of the wheel that is entering into the
pinch point can dig into the surface of the material causing
the wheel to climb out or kick out. The wheel may either
jump toward or away from the operator, depending on direc-
tion of the wheel's movement at the point of pinching. Abras-
ive wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
Maintain a firm grip with both hands on the power tool
u
and position your body and arms to allow you to resist
kickback forces. Always use auxiliary handle, if
provided, for maximum control over kickback or
torque reaction during start-up. The operator can con-
trol torque reactions or kickback forces, if proper precau-
tions are taken.
Never place your hand near the rotating accessory.
u
Accessory may kickback over your hand.
Do not position your body in the area where power
u
tool will move if kickback occurs. Kickback will propel
the tool in direction opposite to the wheel's movement at
the point of snagging.
Use special care when working corners, sharp edges,
u
etc. Avoid bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a tendency to
snag the rotating accessory and cause loss of control or
kickback.
Do not attach a saw chain woodcarving blade, seg-
u
mented diamond wheel with a peripheral gap greater
than 10 mm or toothed saw blade. Such blades create
frequent kickback and loss of control.
Safety warnings specific for grinding operations:
Use only wheel types that are specified for your power
u
tool and the specific guard designed for the selected
wheel. Wheels for which the power tool was not designed
cannot be adequately guarded and are unsafe.
The grinding surface of centre depressed wheels must
u
be mounted below the plane of the guard lip. An im-
properly mounted wheel that projects through the plane
of the guard lip cannot be adequately protected.
The guard must be securely attached to the power tool
u
and positioned for maximum safety, so the least
amount of wheel is exposed towards the operator.
The guard helps to protect the operator from broken
wheel fragments, accidental contact with wheel and
sparks that could ignite clothing.
Wheels must be used only for specified applications.
u
For example: do not grind with the side of cut-off
wheel. Abrasive cut-off wheels are intended for peri-
Bosch Power Tools
pheral grinding, side forces applied to these wheels may
cause them to shatter.
Always use undamaged wheel flanges that are of cor-
u
rect size and shape for your selected wheel. Proper
wheel flanges support the wheel thus reducing the pos-
sibility of wheel breakage. Flanges for cut-off wheels may
be different from grinding wheel flanges.
Do not use worn down wheels from larger power tools.
u
A wheel intended for larger power tool is not suitable for
the higher speed of a smaller tool and may burst.
When using dual purpose wheels always use the cor-
u
rect guard for the application being performed. Failure
to use the correct guard may not provide the desired level
of guarding, which could lead to serious injury.
Additional safety information
Wear safety goggles.
Hold the power tool firmly with both hands
and make sure you have a stable footing. The
power tool can be more securely guided with
both hands.
Use suitable detectors to determine if utility lines are
u
hidden in the work area or call the local utility com-
pany for assistance. Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to
explosion. Penetrating a water line causes property dam-
age or may cause an electric shock.
Release the On/Off switch and set it to the off position
u
when the power supply is interrupted, e. g., in case of
a power failure or when the mains plug is pulled. This
prevents uncontrolled restarting.
Do not touch grinding discs until they have cooled
u
down. The discs can become very hot while working.
Secure the workpiece. A workpiece clamped with
u
clamping devices or in a vice is held more secure than by
hand.
Products sold in GB only:
Your product is fitted with an BS 1363/A approved electric
plug with internal fuse (ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an au-
thorised customer service agent. The replacement plug
should have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains
socket elsewhere.
Use a dust extractor when working with stone. The
u
dust extractor must be approved for extracting stone
dust. Use of this equipment can reduce the risks posed
by dust.
