Safety instructions for Sanding Roller
Safety warnings that are common for sanding or wire
brushing
 This power tool is intended to function as a sander or
wire brush. Read all safety warnings, instructions, il-
lustrations and specifications provided with this power
tool. Failure to follow all instructions listed below may re-
sult in electric shock, fire and/or serious injury.
 Operations such as polishing or cutting-off are not rec-
ommended to be performed with this power tool. Oper-
ations for which the power tool was not designed may cre-
ate a hazard and cause personal injury.
 Do not use accessories which are not specifically de-
signed and recommended by the tool manufacturer.
Just because the accessory can be attached to your power
tool, it does not assure safe operation.
 The rated speed of the accessory must be at least equal
to the maximum speed marked on the power tool. Ac-
cessories running faster than their rated speed can break
and fly apart.
 Do not use a damaged accessory. Before each use,
check application tools such as sanding sleeves and la-
mella rolls for chips and cracks, the shank for cracks,
wear or heavy wear, and wire brushes for loose or bro-
ken wires. If the machine or application tool is
dropped, inspect for damage or install an undamaged
application tool. After inspecting and installing the ap-
plication tool, position yourself and bystanders away
from the plane of the rotating application tool and run
the power tool at maximum no-load speed for one min-
ute. Damaged application tools will normally break apart
during this test time.
 Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing pro-
tectors, gloves and shop apron capable of stopping
small abrasive or workpiece fragments. The eye protec-
tion 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 operation.
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 accessory may fly away and cause injury beyond
immediate area of operation.
 Hold the power tool by insulated gripping surfaces on-
ly, when performing an operation where the cutting ac-
cessory may contact hidden wiring or its own cord. Cut-
ting accessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give the op-
erator an electric shock.
 Position the cord clear of the spinning accessory. If you
lose control, the cord may be cut or snagged and your hand
or arm may be pulled into the spinning wheel.
Bosch Power Tools
 Never lay the power tool down until the accessory has
come to a complete stop. The spinning wheel 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 ac-
cumulation of powdered metal may cause electrical haz-
ards.
 Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
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.
Additional safety warnings
Wear safety goggles.
Wear protective gloves.
 Switch the power tool off when the power supply is in-
terrupted, e.g. as a result of a power cut or the plug be-
ing pulled. This prevents an uncontrolled restart.
 Hold the power tool by the insulated gripping surfaces
because the sanding tool can strike its own mains ca-
ble. Damaging a live cable can make metal parts of the tool
"live" and lead to an electric shock.
 Use the machine only for dry sanding. Penetration of wa-
ter into the machine increases the risk of an electric shock.
 Apply the machine to the workpiece only when
switched on and switch the machine off only after it has
been lifted away from the workpiece. The power tool
can move suddenly.
 Never touch the sanding tool when it is running. This
poses a risk of injury.
 Pay attention that no persons are put at risk through
sparking. Remove any combustible materials in the vi-
cinity. Sparking occurs when sanding metal materials.
 Do not use any worn, torn or severely clogged sanding
tools. Damaged sanding tools can tear, fly off and injure
someone.
 Regularly clean the power tool's air vents. The motor's
fan will draw the dust inside the housing and excessive ac-
cumulation of powdered metal may cause electrical haz-
ards.
 Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
