The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN60745 and may be used to compare one tool with another. It may be used for a preliminary assessment ofexposure.

WARNING: The declared vibration emission level represents the main applications of the tool. However if



the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total workingperiod.

An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total workingperiod.

Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of workpatterns.

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, 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.

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 flammable 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.

Unmodified 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 or 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 influence 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 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.

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 off. 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 affect 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 different

from those intended could result in a hazardoussituation.

5) Battery tool use and care

a ) Recharge only with the charger specified by the

manufacturer. A charger that is suitable for one type

of battery pack may create a risk of fire when used with another batterypack.

b ) Use power tools only with specifically designated

battery packs. Use of any other battery packs may create a risk of injury andfire.

c ) When battery pack is not in use, keep it away from

other metal objects like paper clips, coins, keys, nails, screws or other small metal objects that can make a connection from one terminal to another.

Shorting the battery terminals together may cause burns or afire.

d ) Under abusive conditions, liquid may be ejected

from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid

ejected from the battery may cause irritation orburns.

6) Service

a ) 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.

ADDITIONAL SPECIFIC SAFETY RULES

Safety Instructions for All Operations

a ) This power tool is intended to function as a

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

ENGLISH

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.

b ) 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.

c ) Do not use accessories which are not specifically

designed and recommended by the tool manufacturer. Just because the accessory can

be attached to your power tool, it does not assure safeoperation.

d ) 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.

e ) The outside diameter and the thickness of your

accessory must be within the capacity rating of your power tool. Incorrectly sized accessories can not be

adequately guarded orcontrolled.

f ) 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.

g ) Do not use a damaged accessory. Before each use

inspect the accessory such as abrasive wheel 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.

h ) 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.

i ) 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.

j ) Hold the power tool by insulated gripping surfaces

only, when performing an operation where the

ENGLISH

cutting tool may contact hidden wiring. Contact with a "live" wire will also make exposed metal parts of the power tool "live" and could give the operator an electricshock.

k ) 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.

l ) 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.

m ) 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.

n ) Do not operate the power tool near flammable

materials. Sparks could ignite thesematerials.

o ) Do not use accessories that require liquid coolants.

Using water or other liquid coolants may result in electrocution orshock.

FURTHER SAFETY INSTRUCTIONS FOR ALL OPERATIONS

Causes and Operator Prevention of Kickback

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:

a ) 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

reaction or kickback forces, if proper precautions aretaken.

b ) Never place your hand near the rotating accessory.

Accessory may kickback over yourhand.

c ) 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.

d ) 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.

e ) 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

a ) 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.

b ) 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.

c ) 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 the operator from broken wheel fragments and accidental contact with wheel and sparks that could igniteclothing.

d ) Wheels must be used only for recommended

applications. For example: do not grind with the side of cut-off wheel. Abrasive cut-off wheels are intended

for peripheral grinding, side forces applied to these wheels may cause them toshatter.

e ) Always use undamaged wheel flanges that are

of correct 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.

f ) 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

a ) 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.

b ) Do not position your body in line with and behind

the rotating wheel. When the wheel, at the point of operations, is moving away from your body, the possible kickback may propel the spinning wheel and the power tool directly atyou.

c ) 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
