position yourself and bystanders away from
the plane of the rotating accessory and run
the power tool at maximum no-load speed
for one minute. Damaged accessories will
normally break apart during this test time.
Wear personal protective equipment. De-
pending on application, use face shield, safe-
ty goggles or safety glasses. As appropriate,
wear dust mask, hearing protectors, gloves
and workshop apron capable of stopping
small abrasive or workpiece fragments. The
eye protection must be capable of stopping
flying debris generated by various operations.
The dust mask or respirator must be capable
of filtrating particles generated by your opera-
tion. Prolonged exposure to high intensity
noise may cause hearing loss.
Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken ac-
cessory may fly away and cause injury be-
yond immediate area of operation.
Hold power tool by insulated gripping sur-
faces only, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord. Cutting ac-
cessory contacting a "live" wire may make ex-
posed metal parts of the power tool "live"
and shock the operator.
Position the cord clear of the spinning ac-
cessory. If you lose control of the power tool,
the cord may be cut or snagged and your
hand or arm may be pulled into the spinning
accessory.
Never lay the power tool down until the ac-
cessory 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 pow-
dered metal may cause electrical hazards.
Bosch Power Tools
Do not operate the power tool near flamma-
ble materials. Sparks could ignite these ma-
terials.
Do not use accessories that require liquid
coolants. Using water or other liquid cool-
ants 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 accesso-
ry which in turn causes the uncontrolled
power tool to be forced in the direction op-
posite 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 caus-
ing the wheel to climb out or kick out. 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 pre-
cautions 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.
