General Power Tool Safety Warnings

WARNING Read all safety warnings and all

instructions. Failure to follow the warnings and

instructions may result in electric shock, fi e and/

or serious 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.

1) Work area safety

a) Keep work area clean and well lit. Cluttered

or dark areas invite accidents.

b) Do not operate power tools in explosive

atmospheres, such as in the presence of

ammable liquids, gases or dust. Power

tools create sparks which may ignite the

dust or fumes.

c) Keep children and bystanders away

while operating a power tool. Distractions

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. Unmodifie

plugs and matching outlets will reduce

risk of electric shock.

b) 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.

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 outdoor

use. Use of a cord suitable for outdoor

use reduces the risk of electric shock.

f) If operating a power tool in a damp location

is unavoidable, use a residual current

device (RCD) protected supply. Use of an RCD

reduces the risk of electric shock.

3) Personal safety

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 inuence

of drugs, alcohol or medication. A moment

of inattention while operating power tools may

result in serious personal injury.

b) 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.

c) Prevent unintentional starting. Ensure

the switch is in the o-position before

connecting to power source and/or battery

pack, picking up or carrying the

tool. Carrying power tools with your finge

on the switch or energising power tools that have

the switch on invites accidents.

d) 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.

e) Do not overreach. Keep proper footing

and balance at all times. This enables

better control of the power tool in unexpected

situations.

f) Dress properly. Do not wear loose clothing

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 connection

of dust extraction and collection facilities,

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 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.

b) Do not use the power tool if the switch

does not turn it on and o. Any power

tool that cannot be controlled with the

switch is dangerous and must be repaired.

c) 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.

d) 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.

e) Maintain power tools. Check for

misalignment or binding of moving parts,

breakage of parts and any other condition

that may aect the power tool’s operation.

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. Properly

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 instructions,

taking into account the working conditions

and the work to be performed. Use of the

power tool for operations dierent from those

intended could result in a hazardous situation.

5) Service

a) Have your power tool serviced by a qualied

repair person using only identical

replacement parts. This will ensure that

the safety of the power tool is maintained.

4. Special safety instructions

Safety Warnings Common for Grinding,

Sanding, Wire Brushing or Abrasive Cutting-

O Operations

• This power tool is intended to function as a

grinder, sander, wire brush or cut-o tool.

Read all safety warnings, instructions,

illustrations and specications provided with

this power tool. Failure to follow all instructions

listed below may result in electric shock, fi e and/

or serious injury.

• 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.

• Do not use accessories which are not

specically designed 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. Accessories running faster

than their rated speed can break and fly apa t.

• 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

or controlled.

• The arbor size of wheels, anges, backing

pads or any other accessory must properly

t the spindle of the power tool. Accessories

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.

• Do not use a damaged accessory. Before

each use, inspect the accessory such as

abrasive wheels for chips and cracks, backing

pads for cracks, tears or excess wear, wire

brushes 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 deb is generated by

various operations. The dust mask or respirator

must be capable of filt ating particles generated

by your operation. Prolonged exposure to high

intensity noise may cause hearing loss.

• Keep bystanders a safe distance away from

the work area. Anyone entering the work area

must wear personal protective equipment.

Fragments of workpiece or of a broken

accessory may fly way and cause injury beyond

immediate area of operation.

• Hold the power tool only by the insulated

gripping surfaces when performing an

operation where the cutting accessory may

contact hidden wiring or its own cord. Contact

with a “live” wire will also make exposed

metal parts of the power tool “live” and

shock the operator.

• Position the cord clear of the spinning

accessory. 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 accessory.

• 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.

• 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

ammable materials. Sparks could ignite these

materials.

• 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.

• Maintain a rm 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. The accessory may kickback over

your hand.

• Do not position your body in the area where

the power tool will move if kickback occurs.

Kickback will propel the tool in the 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. Corners, 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

over the power tool.

Additional safety instructions for grinding

and cutting o operations

• Use only wheel types that are recommended

for your power tool and the specic guard

designed for the selected wheel. Wheels for

which the power tool was not designed cannot

be adequately guarded and are unsafe.

• 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 and accidental contact with

wheel.

• Wheels must be used only for recommended

applications. For example: do not grind

with the side of the cut-off whee . Abrasive

cut-off wheels a e intended for peripheral

grinding; side forces applied to these wheels

may cause them to shatter.

• Always use undamaged wheel anges that

are of correct size and shape for your selected

wheel. Proper wheel flanges suppo t

the wheel thus reducing the possibility of

wheel breakage. Flanges for cut-off wheel

may be dierent from grinding wheel flange .

• 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 or

abrasive cutting off ope ations

• Do not “jam” the cut-o 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.

• 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 o the power

tool and hold the power tool motionless until

the wheel comes to a complete stop. Never

attempt to remove the cut-o wheel from

the cut while the wheel is in motion, otherwise

kickback may occur. Investigate and

take corrective action to eliminate the cause

of wheel binding.

• Do not restart the cutting operation in the

workpiece. Let the wheel reach full speed

and carefully reenter 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 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.

• Use extra caution when making a “pocket

cut” into existing walls or other blind areas.

The protruding wheel may cut gas or water

pipes, electrical wiring or objects that can

cause kickback.

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 fi e

and electric shock. Damaging a gas line can

lead to explosion. Penetrating a water line

causes property damage or may cause an

electric shock.

• Release the On/O switch and set it to the

o position when the power supply is

interrupted, e. g., in case of a power failure or

when the mains plug is pulled. This prevents

uncontrolled restarting.

• 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.

• Use a cutting guide when cutting stone.

Without sideward guidance, the cutting disc

can jam and cause kickback.

• When working with the machine, always

hold it rmly with both hands and provide

for a secure stance. The power tool is guided

more secure with both hands.

• Secure the workpiece. A workpiece clamped

with clamping devices or in a vice is held

more secure than by hand.

• Keep your workplace clean. Blends of

materials are particularly dangerous. Dust from

light alloys can burn or explode.

• Never use the machine with a damaged cable.

Do not touch the damaged cable and

pull the mains plug when the cable is damaged

while working. Damaged cables increase

the risk of an electric shock.

Important.

Read the instructions for use before

starting the machine.

Wear safety goggles.

Wear ear protection.

Wear good quality, strong gloves.

Always use breathing apparatus when

machining materials which generate

dust.

End of life machines contain valuable

materials and therefore they should not

be placed in household waste.

We would ask you to play your part in

protecting resources and help protect

the environment by returning this

machine to a return point (if one is

available) when it reaches the end of its

life.
