General Power Tool Safety Warnings

Read all safety warnings and all

instructions. Failure to follow

the warnings and instructions may result in elec-

tric shock, fire and/or serious injury.

Save all warnings and instructions for future

The term “power tool” in the warnings refers to

your mains-operated (corded) power tool or

battery-operated (cordless) power tool.

a) Keep work area clean and well lit. Clut-

tered or dark areas invite accidents.

b) 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

c) Keep children and bystanders away

while operating a power tool. Distrac-

tions can cause you to lose control.

2) Electrical safety

a) 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.

b) Avoid body contact with earthed or

grounded surfaces, such as pipes, radia-

tors, ranges and refrigerators. There is

an increased risk of electric shock if your

body is earthed or grounded.

c) Do not expose power tools to rain or wet

conditions. Water entering a power tool

will increase the risk of electric shock.

d) 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.

e) When operating a power tool outdoors,

use an extension cord suitable for out-

door use. Use of a cord suitable for out-

door use reduces the risk of electric

f) If operating a power tool in a damp loca-

tion is unavoidable, use a residual cur-

rent device (RCD) protected supply. Use

of an RCD reduces the risk of electric

a) 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 influ-

ence of drugs, alcohol or medication. A

moment of inattention while operating

power tools may result in serious person-

b) Use personal protective equipment. Al-

ways wear eye protection. Protective

equipment such as dust mask, non-skid

safety shoes, hard hat, or hearing protec-

tion used for appropriate conditions will

reduce personal injuries.

c) Prevent unintentional starting. Ensure

the switch is in the off-position before

connecting to power source and/or bat-

tery pack, picking up or carrying the

tool. Carrying power tools with your fin-

ger on the switch or energising power

tools that have the switch on invites acci-

d) Remove any adjusting key or wrench be-

fore turning the power tool on. A wrench

or a key left attached to a rotating part of

the power tool may result in personal inju-

e) Do not overreach. Keep proper footing

and balance at all times. This enables

better control of the power tool in unex-

f) Dress properly. Do not wear loose cloth-

ing or jewellery. Keep your hair, clothing

and gloves away from moving parts.

Loose clothes, jewellery or long hair can

be caught in moving parts.

g) If devices are provided for the connec-

tion of dust extraction and collection fa-

cilities, ensure these are connected and

properly used. Use of dust collection can

reduce dust-related hazards.

4) Power tool use and care

a) Do not force the power tool. Use the cor-

rect power tool for your application. The

correct power tool will do the job better

and safer at the rate for which it was de-

b) 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 re-

c) Disconnect the plug from the power

source and/or the battery pack from the

power tool before making any adjust-

ments, changing accessories, or storing

power tools. Such preventive safety

measures reduce the risk of starting the

power tool accidentally.

d) Store idle power tools out of the reach of

children and do not allow persons unfa-

miliar with the power tool or these in-

structions to operate the power tool.

Power tools are dangerous in the hands of

e) Maintain power tools. Check for mis-

alignment or binding of moving parts,

breakage of parts and any other condi-

tion that may affect the power tool’s op-

eration. If damaged, have the power tool

repaired before use. Many accidents are

caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Prop-

erly maintained cutting tools with sharp

cutting edges are less likely to bind and

are easier to control.

g) Use the power tool, accessories and tool

bits etc. in accordance with these in-

structions, taking into account the work-

ing conditions and the work to be per-

formed. Use of the power tool for

operations different from those intended

could result in a hazardous situation.

a) Have your power tool serviced by a qual-

ified repair person using only identical

replacement parts. This will ensure that

the safety of the power tool is maintained.

Safety Warnings for Angle Grinder

Safety Warnings common for Grinding, Sand-

ing, Wire Brushing or Abrasive Cutting Off Op-

f This power tool is intended to function as a

grinder, sander, wire brush or cut-off tool.

Read all safety warnings, instructions, illus-

trations 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.

f This power tool is not recommended for

polishing. Operations for which the power

tool was not designed may create a hazard

and cause personal injury.

f Do not use accessories which are not spe-

cifically designed and recommended by the

tool manufacturer. Just because the acces-

sory can be attached to your power tool, it

does not assure safe operation.

f The rated speed of the accessory must be at

least equal to the maximum speed marked

on the power tool. Accessories running fast-

er than their rated speed can break and fly

f The outside diameter and the thickness of

your accessory must be within the capacity

rating of your power tool. Incorrectly sized

accessories cannot be adequately guarded

f The arbor size of wheels, flanges, backing

pads or any other accessory must properly

fit the spindle of the power tool. Accesso-

ries with arbor holes that do not match the

mounting hardware of the power tool will run

out of balance, vibrate excessively and may

cause loss of control.

f Do not use a damaged accessory. Before

each use inspect the accessory such as

abrasive wheels for chips and cracks, back-

ing 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 accesso-

ry, 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

f Wear personal protective equipment. De-

pending on application, use face shield,

safety goggles or safety glasses. As appro-

priate, wear dust mask, hearing protectors,

gloves and workshop apron capable of stop-

ping small abrasive or workpiece frag-

ments. The eye protection must be capable

of stopping flying debris generated by vari-

ous operations. The dust mask or respirator

must be capable of filtrating particles gener-

ated by your operation. Prolonged exposure

to high intensity noise may cause hearing

f 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 ac-

cessory may fly away and cause injury be-

yond immediate area of operation.

f Hold power tool by insulated gripping sur-

faces only, when performing an operation

where the cutting accessory may contact

hidden wiring or its own cord. Cutting ac-

cessory contacting a “live” wire may make ex-

posed metal parts of the power tool “live”

and shock the operator.

f Position the cord clear of the spinning ac-

cessory. If you lose control of the power tool,

the cord may be cut or snagged and your

hand or arm may be pulled into the spinning

f Never lay the power tool down until the ac-

cessory has come to a complete stop. The

spinning accessory may grab the surface and

pull the power tool out of your control.

f 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.

f Regularly clean the power tool’s air vents.

The motor’s fan will draw the dust inside the

housing and excessive accumulation of pow-

dered metal may cause electrical hazards.

f Do not operate the power tool near flamma-

ble materials. Sparks could ignite these ma-

f Do not use accessories that require liquid

coolants. Using water or other liquid cool-

ants may result in electrocution or shock.

Kickback and related warnings

f 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 accesso-

ry which in turn causes the uncontrolled

power tool to be forced in the direction op-

posite 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 caus-

ing 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

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.

Bosch Power Tools 1 609 929 T63 | (26.1.09)

f 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 re-

actions or kickback forces, if proper precau-

f Never place your hand near the rotating ac-

cessory. Accessory may kickback over your

f Do not position your body in the area where

power tool will move if kickback occurs.

Kickback will propel the tool in direction op-

posite to the wheel’s movement at the point

f Use special care when working corners,

sharp edges, etc. Avoid bouncing and snag-

ging the accessory. Corners, sharp edges or

bouncing have a tendency to snag the rotat-

ing accessory and cause loss of control or

f Do not attach a saw chain woodcarving

blade or toothed saw blade. Such blades

create frequent kickback and loss of control

over the power tool.

Additional safety instructions for grinding and

cutting off operations

f Use only wheel types that are recommend-

ed 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

f The guard must be securely attached to the

power tool and positioned for maximum

safety, so the least amount of wheel is ex-

posed towards the operator. The guard

helps to protect operator from broken wheel

fragments and accidental contact with

f Wheels must be used only for recommend-

ed applications. 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.

f Always use undamaged wheel flanges that

are of correct size and shape for your se-

lected 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.

f Do not use worn down 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 abra-

sive cutting off operations

f Do not “jam” the cut-off wheel or apply ex-

cessive pressure. Do not attempt to make

an excessive depth of cut. Overstressing the

wheel increases the loading and susceptibili-

ty to twisting or binding of the wheel in the

cut and the possibility of kickback or wheel

f 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.

f When wheel is binding or when interrupting

a cut for any reason, switch off the power

tool and hold the power tool motionless un-

til the wheel comes to a complete stop. Nev-

er attempt to remove the cut-off wheel from

the cut while the wheel is in motion other-

wise kickback may occur. Investigate and

take corrective action to eliminate the cause

f Do not restart the cutting operation in the

workpiece. Let the wheel reach full speed

and carefully reenter the cut.

bind, walk up or kickback if the power tool is

restarted in the workpiece.

f Support panels or any oversized workpiece

to minimize the risk of wheel pinching and

kickback. Large workpieces tend to sag un-

der 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.

and electric shock. Damaging a gas line can

lead to explosion. Penetrating a water line

causes property damage or may cause an

f 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.

f Use a cutting guide when cutting stone.

Without sideward guidance, the cutting disc

can jam and cause kickback.

f When working with the machine, always

hold it firmly with both hands and provide

for a secure stance. The power tool is guided

more secure with both hands.

f Secure the workpiece. A workpiece clamped

with clamping devices or in a vice is held

more secure than by hand.

f Keep your workplace clean. Blends of mate-

rials are particularly dangerous. Dust from

light alloys can burn or explode.

f Never use the machine with a damaged ca-

ble. Do not touch the damaged cable and

pull the mains plug when the cable is dam-

aged while working. Damaged cables in-

crease the risk of an electric shock.

For cutting stone, it is best to use a diamond

cutting disc. As a safety measure against jam-

ming, the cutting guide with dust extraction pro-

tection guard 21 must be used.

Operate the machine only with dust extraction

and additionally wear a dust protection mask.

The vacuum cleaner must be approved for the

extraction of masonry dust. Bosch provides suit-

able vacuum cleaners.

For cutting expecially hard material, e. g., con-

crete with high pebble content, the diamond

cutting disc can overheat and become damaged

as a result. This is clearly indicated by circular

sparking, rotating with the diamond cutting

In this case, interrupt the cutting process and al-

low the diamond cutting disc to cool by running

the machine for a short time at maximum speed

Noticeable decreasing work progress and circu-

lar sparking are indications of a diamond cutting

disc that has become dull. Briefly cutting into

abrasive material (e. g. lime-sand brick) can re-

sharpen the disc again.
