Kickback And Related Warnings; Safety Warnings Specific For Grinding And Abrasive Cutting-Off Operations - Bosch GWS18V-8B15 Operating/Safety Instructions Manual

personal protective equipment. Fragments of
workpiece or of a broken accessory may fly away and
cause injury beyond immediate area of operation.
Hold the power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring. Cutting
accessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give the
operator an electric shock.
Never lay the power tool down until the accessory
has come to a complete stop. The spinning accessory
may grab the surface and pull the power tool out of your
control.
Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into your
body.
Regularly clean the power tool's air vents. The
motor's fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electrical hazards.
Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.

Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other
accessory. Pinching or snagging causes rapid stalling
of the rotating accessory 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 kickout. The wheel may either jump toward or away
from the operator, depending on direction of the wheel's
movement at the point of pinching. Abrasive 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 on the power tool and position
your body and arm 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 control torque

reactions or kickback forces, if proper precautions are
taken.
Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
Do not position your body in the area where power
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 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 or
toothed saw blade. Such blades create frequent
kickback and loss of control.
Safety Warnings Specific for
Grinding and Abrasive
Cutting-Off Operations:
Use only wheel types that are recommended for
your power 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 be mounted below the plane of the guard lip.
An improperly 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 and positioned for maximum safety, so the
least amount of wheel is exposed towards the
operator. The guard helps to protect operator from
broken wheel fragments, accidental contact with
wheel and sparks that could ignite clothing.
Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
Always use undamaged wheel flanges that are of
correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing
the possibility 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. Wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and may
burst.
