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.

English

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

English

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 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.

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.

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.

English

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.

English

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) 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. Never start the tool with a person in line with the wheel. This includes the operator.

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:

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 Speciﬁ c 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 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 Speciﬁ c 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.
