Safety Notes

General Power Tool Safety Warnings

Read all safety warnings and all instruc-

tions. 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.

Work area safety

 Keep work area clean and well lit. Cluttered or dark areas

invite accidents.

 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.

 Keep children and bystanders away while operating a

power tool. Distractions can cause you to lose control.

Electrical safety

 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.

 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.

 Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of electric

shock.

 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.

 When operating a power tool outdoors, use an exten-

sion cord suitable for outdoor use. Use of a cord suitable

for outdoor use reduces the risk of electric shock.

 If operating a power tool in a damp location is unavoid-

able, use a residual current device (RCD) protected

supply. Use of an RCD reduces the risk of electric shock.

Personal safety

 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 op-

erating power tools may result in serious personal injury.

 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.

 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.

 Remove any adjusting key or wrench before turning

the power tool on. A wrench or a key left attached to a ro-

tating part of the power tool may result in personal injury.

 Do not overreach. Keep proper footing and balance at

all times. This enables better control of the power tool in

unexpected situations.

 Dress properly. Do not wear loose clothing or jewel-

lery. Keep your hair, clothing and gloves away from

moving parts. Loose clothes, jewellery or long hair can be

caught in moving parts.

 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.

Power tool use and care

 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.

 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.

 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.

 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.

 Maintain power tools. Check for misalignment or bind-

ing 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.

 Keep cutting tools sharp and clean. Properly maintained

cutting tools with sharp cutting edges are less likely to bind

and are easier to control.

 Use the power tool, accessories and tool bits etc. in ac-

cordance 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.

Service

 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.

Cut-off machine safety warnings

 The guard provided with the tool must be securely

attached to the power tool and positioned for maxi-

mum safety, so the least amount of wheel is exposed

towards the operator. Position yourself and bystand-

ers away from the plane of the rotating wheel. The

guard helps to protect operator from broken wheel frag-

ments and accidental contact with wheel.

 Use only diamond cut-off wheels for your power tool.

Just because an 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 apart.

 Wheels must be used only for recommended applica-

tions. 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.

 Always use undamaged wheel flanges that are of cor-

rect diameter for your selected wheel. Proper wheel

flanges support the wheel thus reducing the possibility of

wheel breakage.

 The outside diameter and the thickness of your acces-

sory must be within the capacity rating of your power

tool. Incorrectly sized accessories cannot be adequately

controlled.

 The arbour size of wheels and flanges must properly fit

the spindle of the power tool. Wheels and flanges with

arbour 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 damaged wheels. Before each use, inspect

the wheels for chips and cracks. If power tool or wheel

is dropped, inspect for damage or install an undam-

aged wheel. After inspecting and installing the wheel,

position yourself and bystanders away from the plane

of the rotating wheel and run the power tool at maxi-

mum no load speed for one minute. Damaged wheels 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 pro-

tectors, gloves and workshop apron capable of stop-

ping small abrasive or workpiece fragments. The eye

protection must be capable of stopping flying debris gen-

erated 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.

 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.

 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 ex-

posed metal parts of the power tool “live” and could give

the operator an electric shock.

 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 wheel.

 Never lay the power tool down until the accessory has

come to a complete stop. The spinning wheel 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 flammable materi-

als. Sparks could ignite these materials.

 Do not use accessories that require liquid coolants.

Using water or other liquid coolants may result in electro-

cution or shock.

Kickback and related warnings

 Kickback is a sudden reaction to a pinched or snagged ro-

tating wheel. Pinching or snagging causes rapid stalling of

the rotating wheel which in turn causes the uncontrolled

power tool to be forced in the direction opposite of the

wheel’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 pinch-

ing. Abrasive wheels may also break under these condi-

tions.

Kickback is the result of power tool misuse and/or incor-

rect operating procedures or conditions and can be avoid-

ed by taking proper precautions as given below.

 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 reactions or

kickback forces, if proper precautions are taken.

 Never place your hand near the rotating accessory.

Accessory may kickback over your hand.

 Do not position your body in line with the rotating

wheel. Kickback will propel the tool in 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. Cor-

ners, sharp edges or bouncing have a tendency to snag the

rotating accessory and cause loss of control or kickback.
