Safety instructions

General Power Tool Safety Warnings

WARNING

warnings and 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-operated (cord­less) power tool.

Work area safety

u Keep work area clean and well lit. Cluttered or dark

areas invite accidents.

u 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.

u Keep children and bystanders away while operating a

power tool. Distractions can cause you to lose control.

Electrical safety

u 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.

u Avoid body contact with earthed or grounded sur-

faces, such as pipes, radiators, ranges and refrigerat­ors. There is an increased risk of electric shock if your

body is earthed or grounded.

u Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of elec­tric shock.

u Do not abuse the cord. Never use the cord for carry-

ing, pulling or unplugging the power tool. Keep cord
away from heat, oil, sharp edges or moving parts.

Damaged or entangled cords increase the risk of electric
shock.

u 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..

u If operating a power tool in a damp location is un-

avoidable, use a residual current device (RCD) protec­ted supply. Use of an RCD reduces the risk of electric

shock.

Personal safety

u 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 inatten-

tion while operating power tools may result in serious per­sonal injury.

Read all safety warnings and all in­structions. Failure to follow the

u 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.

u 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 en­ergising power tools that have the switch on invites acci­dents.

u Remove any adjusting key or wrench before turning

the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal in­jury.

u Do not overreach. Keep proper footing and balance at

all times. This enables better control of the power tool in
unexpected situations.

u Dress properly. Do not wear loose clothing or jew-

ellery. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewellery or long hair can

be caught in moving parts.

u 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

u 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.

u 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.

u 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.

u 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.

u 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.

u Keep cutting tools sharp and clean. Properly main-

tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.

u Use the power tool, accessories and tool bits etc. in

accordance with these instructions, taking into ac­count the working conditions and the work to be per-

1 609 92A 6E9 | (25.11.2020) Bosch Power Tools

formed. Use of the power tool for operations different
from those intended could result in a hazardous situation.

Service

u Have your power tool serviced by a qualified repair

person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.

Safety information for the angle grinder

Safety Warnings common for Grinding, Sanding, Wire Brushing or Abrasive Cutting Off operations

u 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

instructions listed below may result in electric shock, fire
and/or serious injury.

u 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.

u 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.

u The rated speed of the accessory must be at least

equal to the maximum speed marked on the power
tool. Accessories running faster than their rated speed

can break and fly apart.

u The outside diameter and the thickness of your ac-

cessory must be within the capacity rating of your
power tool. Incorrectly sized accessories cannot be ad-

equately guarded or controlled.

u 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.

u 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.

u 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 gen-

erated 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.

u 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.

u Hold the power tool by insulated gripping surfaces

only, when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.

Cutting accessory contacting a "live" wire may make ex­posed metal parts of the power tool "live" and could give
the operator an electric shock.

u 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 accessory.

u 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.

u 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.

u 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.

u Do not operate the power tool near flammable materi-

als. Sparks could ignite these materials.

u 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 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.

u 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

Bosch Power Tools 1 609 92A 6E9 | (25.11.2020)

during start-up. The operator can control torque reac-

tions or kickback forces, if proper precautions are taken.

u Never place your hand near the rotating accessory.

Accessory may kickback over your hand.

u 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.

u 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.

u 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

u 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.

u The grinding surface of 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.

u 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.

u Wheels must be used only for recommended applica-

tions. For example: do not grind with the side of cut­off wheel. Abrasive cut-off wheels are intended for peri-

pheral grinding, side forces applied to these wheels may
cause them to shatter.

u 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 pos­sibility of wheel breakage. Flanges for cut-off wheels may
be different from grinding wheel flanges.

u Do not use worn down wheels from larger power

tools. Wheel intended for 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

u 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.

u 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 kick-

back may propel the spinning wheel and the power tool
directly at you.

u 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 ac-

tion to eliminate the cause of wheel binding.

u 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.

u Support panels or any oversized workpiece to minim-

ize 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.

u 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

u Do not use excessively oversized sanding disc paper.

Follow manufacturers recommendations, when select­ing sanding paper. Larger sanding paper extending bey-

ond the sanding pad presents a laceration hazard and
may cause snagging, tearing of the disc, or kickback.

Safety Warnings specific for Wire Brushing operations

u 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.

u If the use of a guard is recommended for wire brush-

ing, 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 information

Wear safety goggles.

u 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.

u Do not touch grinding and cutting discs until they have

cooled down. The discs can become very hot while work­ing.

u Release the On/Off switch and set it to the off position

when the power supply is interrupted, e. g., in case of
