be pulled into the spinning accessory.
! 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 kick out. The wheel may either jump toward or away
from the operator, depending on the 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. The
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 the
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:
! Always use the guard designed for the type of wheel you are
using. 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 the operator from broken wheel fragments and accidental
contact with the wheel.
! 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.
! Wheels must be used only for recommended applications. For
example: Do not Grind with the side of a 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. A wheel
intended for a larger power tool is not suitable for the higher speed
of a smaller tool and may burst.
Additional safety warnings specific for abrasive cutting off
operations:
! Do not "jam" the cut-off wheel or apply excessive pressure. Do
not attempt to make An excessive depth of cut. Overstressing
the wheel increases the loading and susceptibility to twisting or
binding of the wheel in the cut and the possibility of kickback or
wheel breakage.
! Do not position your body in line with and behind the rotating
wheel. When the wheel, at the point of operation, is moving away
from your body, the possible kickback may propel the spinning
wheel and the power tool directly at you.
! When the wheel is binding or when interrupting a cut for any
reason, switch off the power tool and hold the power tool
motionless until the wheel comes to a complete stop. Never
attempt to remove the cut-off wheel from the cut while the
wheel is in motion, otherwise kickback may occur. Investigate
and take corrective action to eliminate the cause of wheel binding.
! Do not restart the cutting operation in the workpiece. Let the
wheel reach full speed and carefully re-enter the cut. The wheel
may bind, walk up or kickback if the power tool is restarted in the
workpiece.
! Support panels or any oversized workpiece to minimize the
risk of wheel pinching and kickback. Large workpieces tend to
sag under their own weight. Supports must be placed under the
workpiece near the line of cut and near the edge of the workpiece
on both sides of the wheel.
! Use extra caution when making a "pocket cut" into existing
walls or other blind areas. The protruding wheel may cut gas or
water pipes, electrical wiring or objects that can cause kickback.
Safety warnings specific for sanding operations:
! When sanding, do not use excessively oversized sanding disc
paper. Follow the manufacturers' recommendations when
selecting sanding paper. Larger sanding paper extending beyond
the sanding pad presents a laceration hazard and may cause
snagging, tearing of the disc, or kickback.
Safety warnings specific for polishing operations:
! Do not allow any loose portion of the polishing bonnet or its
attachment strings to Spin freely. Tuck away or trim any loose
attachment strings. Loose and spinning attachment strings can
entangle your fingers or snag on the workpiece.
Safety warnings specific for wire brushing operations:
! Be aware that wire bristles are thrown by the brush even
during ordinary operation. Do not overstress the wires by
applying excessive load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
! If the use of a guard is recommended for wire brushing, do not
allow any interference of the wire wheel or brush with the
guard. Wire wheel or brush may expand in diameter due to work
load and centrifugal forces.
Additional safety instructions:
! Use suitable detectors to determine if utility lines are hidden in
the work area or call the local utility company 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 damage or may cause an electric shock.
! If the power supply should be disconnected, e. g. due to a
power outage or pulling the mains plug, release the On/Off
switch and set it to the Off position. This prevents uncontrolled
restarting.
! When working stone, use dust extraction. The vacuum cleaner
must be approved for the extraction of stone dust. Using this
equipment reduces dust-related hazards.
! Use a cutting guide when cutting stone. Without sideward
guidance, the cutting disc can jam and cause kickback.
Other safety instructions:
! Do not clamp the machine in a vice.
! Always direct the cable to the rear away from the machine.
! Insert plug in power supply socket only when machine is switched
off.
! Apply the machine to the workpiece only when switched on.
! Be careful when cutting grooves, e.g., in load-carrying walls: See
notes on statics.
! When grinding metal, flying sparks are produced. Take care that no
persons are endangered. Because of the danger of fire, no
combustible materials should be located in the vicinity (spark flight
zone).
! Pay attention to the direction of rotation. Always hold the ma-chine so
that sparks and grinding dust fly away from the body.
! Caution! The grinding tool runs on after the machine is switched
off.
! BOSCH can assure flawless functioning of the machine only
when original accessories are used.
