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 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

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, Polishing or Abrasive, Cutting-Off Operations

a ) This power tool is intended to function as a

grinder, sander, wire brush, polisher 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 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.

c ) 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.

d ) 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.

e ) 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.

f ) 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.

ENGLISH

g ) 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.

h ) 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.

i ) 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.

j ) 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.

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.

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

tool. Using inappropriate accessories can result ininjury.

q ) Always use side handle. Tighten the handle

securely. The side handle should always be used to maintain control of the tool at alltimes.

r ) 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.

s ) 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.

t ) 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.

u ) Avoid bouncing the wheel or giving it rough

treatment. If this occurs, stop the tool and inspect the wheel for cracks orflaws.

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

x ) Air vents often cover moving parts and should be

avoided. Loose clothes, jewelry or long hair can be caught in movingparts.

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 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 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 Polishing Operations

a ) Do not allow any loose portion of the polishing

bonnet or its attachment strings to spin freely. Tuck away or trim any loose attachment strings.

Loose and spinning attachment strings can entangle your fingers or snag on theworkpiece.

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.



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 chemicallytreated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.

CAUTION: When not in use, place tool on its side on a stable surface where it will not cause a



tripping or falling hazard. Some tools with large battery packs will stand upright on the battery pack but may be easily knockedover.

• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long hair can be caught in movingparts.

• 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
