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 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

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 ground fault circuit

interrupter (GFCI) protected supply. Use of a GFCI

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 energizing 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

jewelry. Keep your hair, clothing and gloves

away from moving parts. Loose clothes, jewelry 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

ENGLISH

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) 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.

SAFETY INSTRUCTIONS FOR ALL

OPERATIONS

Safety Warnings Common for Grinding,

Sanding, Wire Brushing, Surface Finishing

or Abrasive Cutting-Off Operations

a ) This power tool is intended to function as a

grinder, sander, wire brush, surface finisher

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.

b ) Do not use forpolishing.

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 cannot

be adequately guarded orcontrolled.

f ) Threaded mounting of accessories must match

the grinder spindle thread. For accessories

mounted by flanges, the arbor 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

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.

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 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.

k ) 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.

l ) 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.

m ) 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.

n ) 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.

o ) Do not operate the power tool near flammable

materials. Sparks could ignite thesematerials.

p ) Do not use accessories that require liquid

coolants. Using water or other liquid coolants may

result in electrocution orshock.

q ) Do not use Type 11 (flaring cup) wheels on this

tool. Using inappropriate accessories can result

ininjury.

r ) Always use side handle. Tighten the handle

securely. The side handle should always be used to

maintain control of the tool at alltimes.

s ) When starting the tool with a new or

replacement wheel, or a new or replacement

wire brush installed, hold the tool in a well

protected area and let it run for one minute. If

the wheel has an undetected crack or flaw, it

should burst in less than one minute. If the wire

brush has loose wires, they will be detected.

ENGLISH

Never start the tool with a person in line with the

wheel. This includes theoperator.

t ) Use of accessories not specified in this manual

is not recommended and may be hazardous.

Use of power boosters that would cause the tool

to be driven at speeds greater than its rated speed

constitutesmisuse.

u ) Use clamps or another practical way to secure

and support the workpiece to a stable platform.

Holding the work by hand or against your body leaves

it unstable and may lead to loss ofcontrol.

v ) Avoid bouncing the wheel or giving it rough

treatment. If this occurs, stop the tool and inspect the

wheel for cracks orflaws.

w ) Always handle and store wheels in a carefulmanner.

x ) Do not operate this tool for long periods of time.

Vibration caused by the operating action of this

tool may cause permanent injury to fingers,

hands, and arms. Use gloves to provide extra

cushion, take frequent rest periods, and limit daily

time ofuse.

y ) Air vents often cover moving parts and should be

avoided. Loose clothes, jewelry or long hair can be

caught in movingparts.

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 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 center 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, 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 operation, 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 a complete stop. Never attempt

ENGLISH

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

eliminate the cause of wheelbinding.

d ) 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.

e ) 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.

f ) 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.

Safety Warnings Specific for Sanding

Operations

a ) Do not use excessively oversized sanding disc

paper. Follow manufacturers recommendations,

when selecting sanding paper. Larger sanding

paper extending beyond the sanding pad presents a

laceration hazard and may cause snagging, tearing of

the disc orkickback.

Safety Warnings Specific for Wire

Brushing Operations

a ) 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.

b ) 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 and

centrifugalforces.

c ) Safety goggles or safety glasses with side shields

and a full face shield compliant with ANSI Z87.1

MUST be worn by the operator and others that

are within 50' (15.2 m) of the use of thisproduct.

Additional Safety Information

WARNING: ALWAYS use safety glasses. Everyday

eyeglasses are NOT safety glasses. Also use face or

dust mask if cutting operation is dusty. ALWAYS WEAR

CERTIFIED SAFETYEQUIPMENT:

• ANSI Z87.1 eye protection (CAN/CSA Z94.3),

• ANSI S12.6 (S3.19) hearing protection,

• NIOSH/OSHA/MSHA respiratoryprotection.

WARNING: Some dust created by power sanding,

sawing, grinding, drilling, and other construction

activities contains chemicals known to the State

of California to cause cancer, birth defects or

other reproductive harm. Some examples of these

chemicalsare:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other

masonry products, and

• arsenic and chromium from chemically-

treatedlumber.

Your risk from these exposures varies, depending on how

often you do this type of work. To reduce your exposure to

these chemicals: work in a well ventilated area, and work with

approved safety equipment, such as those dust masks that are

specially designed to filter out microscopicparticles.

• Avoid prolonged contact with dust from power

sanding, sawing, grinding, drilling, and other

construction activities. Wear protective clothing and

wash exposed areas with soap and water. Allowing

dust to get into your mouth, eyes, or lay on the skin may

promote absorption of harmfulchemicals.

WARNING: Use of this tool can generate and/

or disperse dust, which may cause serious and

permanent respiratory or other injury. Always use

NIOSH/OSHA approved respiratory protection

appropriate for the dust exposure. Direct particles

away from face andbody.

WARNING: Always wear proper personal hearing

protection that conforms to ANSI S12.6 (S3.19)

during use. Under some conditions and duration

of use, noise from this product may contribute to

hearingloss.

• An extension cord must have adequate wire size

(AWG or American Wire Gauge) for safety. The smaller

the gauge number of the wire, the greater the capacity

of the cable, that is, 16 gauge has more capacity than 18

gauge. An undersized cord will cause a drop in line voltage

resulting in loss of power and overheating. When using

more than one extension to make up the total length,

be sure each individual extension contains at least the

minimum wire size. The following table shows the correct

size to use depending on cord length and nameplate

ampere rating. If in doubt, use the next heavier gauge. The

lower the gauge number, the heavier thecord.
