Safety Notes
General Power Tool Safety Warnings
Read all safety warnings and all in-
structions. Failure to follow the warnings 
and instructions may result in electric shock, fire and/or seri-
ous injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless) 
power tool.
Work area safety
Keep work area clean and well lit. Cluttered or dark areas 
invite accidents.
Do not operate power tools in explosive atmospheres, 
such as in the presence of flammable liquids, gases or 
dust. Power tools create sparks which may ignite the dust 
or fumes.
Keep children and bystanders away while operating a 
power tool. Distractions can cause you to lose control.
Electrical safety
Power tool plugs must match the outlet. Never modify 
the plug in any way. Do not use any adapter plugs with 
earthed (grounded) power tools. Unmodified plugs and 
matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces, 
such as pipes, radiators, ranges and refrigerators. 
There is an increased risk of electric shock if your body is 
earthed or grounded.
Do not expose power tools to rain or wet conditions. 
Water entering a power tool will increase the risk of electric 
shock.
Do not abuse the cord. Never use the cord for carrying, 
pulling or unplugging the power tool. Keep cord away 
from heat, oil, sharp edges and moving parts. Damaged 
or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a cord suitable 
for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is unavoid-
able, use a residual current device (RCD) protected 
supply. Use of an RCD reduces the risk of electric shock.
Personal safety
Stay alert, watch what you are doing and use common 
sense when operating a power tool. Do not use a power 
tool while you are tired or under the influence of drugs, 
alcohol or medication. A moment of inattention while op-
erating power tools may result in serious personal injury.
Use personal protective equipment. Always wear eye 
protection. Protective equipment such as dust mask, 
non-skid safety shoes, hard hat, or hearing protection 
used for appropriate conditions will reduce personal 
injuries.Prevent unintentional starting. Ensure the switch is in 
the off-position before connecting to power source 
and/or battery pack, picking up or carrying the tool. 
Carrying power tools with your finger on the switch or en-
ergising power tools that have the switch on invites acci-
dents.
Remove any adjusting key or wrench before turning 
the power tool on. A wrench or a key left attached to a ro-
tating part of the power tool may result in personal injury.
Do not overreach. Keep proper footing and balance at 
all times. This enables better control of the power tool in 
unexpected situations.
Dress properly. Do not wear loose clothing or jewel-
lery. Keep your hair, clothing and gloves away from 
moving parts. Loose clothes, jewellery or long hair can be 
caught in moving parts.
If devices are provided for the connection of dust ex-
traction and collection facilities, ensure these are con-
nected and properly used. Use of dust collection can re-
duce dust-related hazards.
Power tool use and care
Do not force the power tool. Use the correct power tool 
for your application. The correct power tool will do the 
job better and safer at the rate for which it was designed.
Do not use the power tool if the switch does not turn it 
on and off. Any power tool that cannot be controlled with 
the switch is dangerous and must be repaired.
Disconnect the plug from the power source and/or the 
battery pack from the power tool before making any 
adjustments, changing accessories, or storing power 
tools. Such preventive safety measures reduce the risk of 
starting the power tool accidentally.
Store idle power tools out of the reach of children and 
do not allow persons unfamiliar with the power tool or 
these instructions to operate the power tool. Power 
tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or bind-
ing of moving parts, breakage of parts and any other 
condition that may affect the power tool’s operation. If 
damaged, have the power tool repaired before use. 
Many accidents are caused by poorly maintained power 
tools.
Keep cutting tools sharp and clean. Properly maintained 
cutting tools with sharp cutting edges are less likely to bind 
and are easier to control.
Use the power tool, accessories and tool bits etc. in ac-
cordance with these instructions, taking into account 
the working conditions and the work to be performed. 
Use of the power tool for operations different from those 
intended could result in a hazardous situation.
Service
Have your power tool serviced by a qualified repair per-
son using only identical replacement parts. This will en-
sure that the safety of the power tool is maintained.

Safety Warnings for Angle Grinder
Safety Warnings common for Grinding, Sanding, Wire 
Brushing or Abrasive Cutting Off Operations
This power tool is intended to function as a grinder, 
sander, wire brush or cut-off tool. Read all safety warn-
ings, instructions, illustrations and specifications pro-
vided with this power tool. Failure to follow all instruc-
tions listed below may result in electric shock, fire and/or 
serious injury.
Operations such as polishing are not recommended to 
be performed with this power tool. Operations for which 
the power tool was not designed may create 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.
The outside diameter and the thickness of your acces-
sory must be within the capacity rating of your power 
tool. Incorrectly sized accessories cannot be adequately 
guarded or controlled.
Threaded mounting of accessories must match the grind-
er spindle thread. For accessories mounted by flanges, 
the arbour hole of the accessory must fit the locating di-
ameter of the flange. Accessories that do not match the 
mounting hardware of the power tool will run out of balance, 
vibrate excessively and may cause loss of control.
Do not use a damaged accessory. Before each use in-
spect the accessory such as abrasive wheels for chips 
and cracks, backing pad for cracks, tear or excess 
wear, wire brush for loose or cracked wires. If power 
tool or accessory is dropped, inspect for damage or in-
stall an undamaged accessory. After inspecting and in-
stalling an accessory, position yourself and bystanders 
away from the plane of the rotating accessory and run 
the power tool at maximum no-load speed for one min-
ute. Damaged accessories 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.
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 accumu-
lation of powdered metal may cause electrical hazards.
Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
Do not use accessories that require liquid coolants. Us-
ing water or other liquid coolants may result in electrocu-
tion or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged ro-
tating 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 accesso-
ry’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 direction of the wheel’s movement at the point of pinch-
ing. Abrasive wheels may also break under these condi-
tions.
Kickback is the result of power tool misuse and/or incor-
rect operating procedures or conditions and can be avoid-
ed 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. Al-
ways 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. Ac-
cessory 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. Cor-
ners, sharp edges or bouncing have a tendency to snag the 
rotating accessory and cause loss of control or kickback.

1 609 92A 0ML | (9.4.14)Bosch Power Tools
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 Cut-
ting-Off operations
Use only wheel types that are recommended for your 
power tool and the specific guard designed for the se-
lected wheel. Wheels for which the power tool was not de-
signed cannot be adequately guarded and are unsafe.
The grinding surface of the 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 frag-
ments, accidental contact with wheel and sparks that 
could ignite clothing.
Wheels must be used only for recommended applica-
tions. For example: do not grind with the side of the 
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 cor-
rect size and shape for your selected wheel. Proper 
wheel flanges support the wheel thus reducing the possi-
bility of wheel breakage. Flanges for cut-off wheels may be 
different from grinding wheel flanges.
Do not use worn down reinforced wheels from larger 
power tools. Wheels intended for larger power tools are 
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 pres-
sure. Do not attempt to make an excessive depth of cut. 
Overstressing the wheel increases the loading and suscep-
tibility 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 wheel is binding or when interrupting a cut for 
any reason, switch off the power tool and hold the pow-
er 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 elimi-
nate 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 work-
pieces 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 ex-
isting 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
Do not use excessively oversized sanding disc paper. 
Follow manufacturers recommendations, when select-
ing sanding paper. Larger sanding paper extending be-
yond the sanding pad presents a laceration hazard and 
may cause snagging, tearing of the disc, or kickback.
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 warnings
Wear safety goggles.
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 explo-
sion. Penetrating a water line causes property damage or 
may cause an electric shock.
Release the On/Off switch and set it to the off position 
when the power supply is interrupted, e. g., in case of a 
power failure or when the mains plug is pulled. This pre-
vents uncontrolled restarting.
Do not touch grinding and cutting discs before they have 
cooled down. The discs can become very hot while working.
Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
Products sold in GB only: Your product is fitted with a 
BS 1363/A approved electric plug with internal fuse (ASTA 
approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be 
cut off and an appropriate plug fitted in its place by an author-
ised customer service agent. The replacement plug should 
have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible 
shock hazard and should never be inserted into a mains sock-
et elsewhere.
Products sold in AUS and NZ only: Use a residual current de-
vice (RCD) with a rated residual current of 30 mA or less.

The integrated vibration damper reduces occurring vibra-
tions.
Do not continue to use the power tool when the damp-
ing element is damaged.
Hand Guard
For operations with the rubber sanding plate 14 or with 
the cup brush/wheel brush/flap disc, always mount the 
hand guard 12.
The hand guard 12 is fastened with the auxiliary handle 3.
Mounting the Grinding Tools
Before any work on the machine itself, pull the mains 
plug.
Do not touch grinding and cutting discs before they 
have cooled down. The discs can become very hot while 
working.
Clean the grinder spindle 4 and all parts to be mounted.
For clamping and loosening the grinding tools, lock the grind-
er spindle with the spindle lock button 1.
Actuate the spindle lock button only when the grinder 
spindle is at a standstill. Otherwise, the machine may be-
come damaged.
Quick-clamping Nut
With the quick-clamping nut 9, grinding tools can be mounted 
without additional tools.
The quick-clamping nut 9 may be used only for grinding 
or cutting discs.
Use only a flawless, undamaged quick-clamping nut 9.
When screwing on, pay attention that the side of the 
quick-clamping nut 9 with printing does not face the 
grinding disc; the arrow must point to the index mark 33.
Lock the grinder spindle with 
the spindle lock button 1. To 
tighten the quick-clamping 
nut, firmly turn the grinding 
disc in clockwise direction.
