Keep bystanders a safe distance away from work area.
u
Anyone entering the work area must wear personal
protective equipment. Fragments of workpiece or of a
broken accessory may fly away and cause injury beyond
immediate area of operation.
Hold power tool by insulated gripping surfaces only,
u
when performing an operation where the cutting ac-
cessory may contact hidden wiring or its own cord.
Cutting accessory contacting a "live" wire may make ex-
posed metal parts of the power tool "live" and could give
the operator an electric shock.
Always hold the tool firmly in your hand(s) during the
u
start-up. The reaction torque of the motor, as it acceler-
ates to full speed, can cause the tool to twist.
Use clamps to support workpiece whenever practical.
u
Never hold a small workpiece in one hand and the tool
in the other hand while in use. Clamping a small work-
piece allows you to use your hand(s) to control the tool.
Round material such as dowel rods, pipes or tubing have
a tendency to roll while being cut, and may cause the bit
to bind or jump toward you.
Position the cord clear of the spinning accessory. If
u
you lose control, 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 accessory has
u
come to a complete stop. The spinning accessory may
grab the surface and pull the power tool out of your con-
trol.
After changing the bits or making any adjustments,
u
make sure the collet nut, chuck or any other adjust-
ment devices are securely tightened. Loose adjustment
devices can unexpectedly shift, causing loss of control,
loose rotating components will be violently thrown.
Do not run the power tool while carrying it at your
u
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
u
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 materi-
u
als. Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
u
Using water or other liquid coolants may result in electro-
cution or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged rotat-
ing wheel, sanding band, brush or any other accessory.
Pinching or snagging causes rapid stalling of the rotating ac-
cessory which in turn causes the uncontrolled power tool to
be forced in the direction opposite of the accessory's rota-
tion.
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
Bosch Power Tools
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 on the power tool and position
u
your body and arm to allow you to resist kickback
forces. The operator can control kickback forces, if
proper precautions are taken.
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 toothed saw blade. Such blades create
u
frequent kickback and loss of control.
Always feed the bit into the material in the same dir-
u
ection as the cutting edge is exiting from the material
(which is the same direction as the chips are thrown).
Feeding the tool in the wrong direction causes the cutting
edge of the bit to climb out of the work and pull the tool in
the direction of this feed.
When using rotary files, high-speed cutters or tung-
u
sten carbide cutters, always have the work securely
clamped. These wheels will grab if they become slightly
canted in the groove, and can kickback.When the rotary
file, high-speed cutter or tungsten carbide cutter grab, it
may jump from the groove and you could lose control of
the tool.
Safety warnings specific for grinding and abrasive
cutting-off operations
Use only wheel types that are recommended for your
u
power tool and only for recommended applications.
For example: do not grind with the side of a cut-off
wheel. Abrasive cut-off wheels are intended for peri-
pheral grinding, side forces applied to these wheels may
cause them to shatter.
For threaded abrasive cones and plugs use only un-
u
damaged wheel mandrels with an unrelieved shoulder
flange that are of correct size and length. Proper man-
drels will reduce the possibility of breakage.
Do not "jam" a cut-off wheel or apply excessive pres-
u
sure. Do not attempt to make an excessive depth of
cut. Overstressing the wheel increases the loading and
susceptibility to twisting or snagging of the wheel in the
cut and the possibility of kickback or wheel breakage.
Do not position your hand in line with and behind the
u
rotating wheel. When the wheel, at the point of opera-
tion, is moving away from your hand, the possible kick-
back may propel the spinning wheel and the power tool
directly at you.
When wheel is pinched, snagged or when interrupting
u
a cut for any reason, switch off the power tool and
hold the power tool motionless until the wheel comes
