Safety Notes
General Power Tool Safety Warnings
WARNING
instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains­operated (corded) power tool or battery-opera ted (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 ig nite 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 w ith 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 th e 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 s uitable
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.

Read all safety warnings and all instruc­tions. Failure to follow the warnings and
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 en­ergising power tools that have the switch on invites acci­dents.
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 con­nected 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 th e 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. I f damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
Keep cutting tools sh arp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind and are easier to control.
Us e 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 Ha ve 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 warn­ings, instructions, illustrations and specifications pro­vided 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
grinder spindle thread. For accessories mounted by flanges, the arbour hole of the accessory must fit the locating diameter 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 in­stall an undamaged accessory. After inspecting and in­stalling 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 min­ute. 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 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 operation. Prolonged exposure to high intensity noise may cause hearing loss.
Keep bystanders a safe distance away from work ar ea.
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.
Bosch Power Tools 1 609 92A 364 | (29.11.16)
Hold the power tool by insulated gripping surfaces on-
ly, when performing an operation where the cutting ac­cessory 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 op­erator 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 ac­cumulation of powdered metal may cause electrical haz­ards.
Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
Do not us e accessories that require liquid coolants. Us-
ing 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 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 accesso­ry’s rotation at the point of the binding. For example, if an abrasive wheel is snagged or pinche d 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 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.
Mai ntain 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.
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.
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.

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 Abrasiv e Cut­ting-Off operations
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 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 frag­ments, 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-
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 select­ing 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.
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 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 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 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.
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.
Relea se the On/Off switch and set it to the off position
whe n the p ower suppl y is in terr upted , e. g ., in case o f 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.
