PERSONAL SAFETY

GENERAL POWER TOOL SAFETY WARNINGS

WORK AREA SAFETY

ELECTRICAL SAFETY

• Keep work area clean and well lit.

 Cluttered or 

dark areas invite accidents.

• Do not operate power tools in explosive atmos-

pheres, such as in the presence of fl ammable 
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.

• 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. 

Unmodifi ed 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 condi-

tions. 

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 
or moving parts. 

Damaged or entangled cords 

increase the risk of electric shock.

• 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.

• 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.

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 

jewellery. Keep your hair, clothing and gloves 
away from moving parts.

 Loose clothes, jewel-

lery 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.

WARNING    

READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS. 

        Failure to follow the warnings and instructions may result in electric shock, fi re 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.

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 pre-

ventive safety measures reduce the risk of starting 
the power tool accidentally.

• Store idle power tools out of the reach of chil-

dren 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 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.

• 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 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.

• 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 infl uence of drugs, alcohol or medication. 

moment of inattention while operating 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 fi nger 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 rotating part of the power tool may 

• Recharge only with the charger specifi ed by 

the manufacturer. 

A charger that is suitable for 

one type of battery pack may create a risk of fi re 
when used with another battery pack.

• Use power tools only with specifi cally desig-

nated battery packs. 

Use of any other battery 

packs may create a risk of injury and fi re.

• When battery pack is not in use, keep it away 

from other metal objects like paper clips,

tection must be capable of stopping fl ying  debris 
generated by various operations. The dust mask 
or respirator must be capable of fi ltrating 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 fl y 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 hid-
den 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.

• 

Never lay the power tool down until the ac-
cessory has come to a complete stop. 

The 

spinning accessory 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 fl ammable 
materials. 

Sparks could ignite these materials.

• 

Do not use accessories that require liquid 
coolants. 

Using water or other liquid coolants 

may result in electrocution or shock.

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 acces-
sory’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.
• 

Maintain a fi rm 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 kick-
back forces, if proper precautions are taken.

• 

Never place your hand near the rotating acces-
sory. 

Accessory may kickback over your hand.

• 

Do not position your body in the area where 
power tool will move if kickback occurs.

SPECIFIC SAFETY RULES

• 

This power tool is intended to function as a 
grinder, sander, wire brushing or cut-off tool. 
Read all safety warnings, instructions, illus-
tr ations and specifi cations provided with this 
power tool.

 Failure to follow all instructions listed 

below may result in electric shock, fi re and/or se-
rious injury

.

• 

Operations such as polishing are not recom-
mended to be performed with this power tool. 

Op-

erations for which the power tool was not designed 
may create a hazard and cause personal injury.

• 

Do not use accessories which are not specifi -
cally designed and recommended by the tool 
manufacturer. 

Just because the 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 fl y apart.

• 

The outside diameter and the thickness of your 
accessory must be within the capacity rating 
of your power tool. 

Incorrectly sized accesso-

ries cannot be adequately guarded or controlled.

• 

The arbour size of wheels, fl anges,  backing 
pads or any other accessory must properly fi t 
the spindle of the power tool. 

Accessories with 

arbour holes that do not match the mounting hard-
ware of the power tool will run out of balance, vi-
brate excessively and may cause loss of control.

• 

Do not use a damaged accessory. Before 
each use inspect the accessory such as 
abrasive wheels for chips and cracks, back-
ing 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.

• 

Wear personal protective equipment. Depend-
ing on application, use face shield, safety gog-
gles or safety glasses. As appropriate, wear 
dust mask, hearing protectors, gloves and 
workshop apron capable of stopping small 
abrasive or workpiece fragments.

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 fi re.

• Under abusive conditions, liquid may be eject-

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

Liquid ejected from the battery may cause irritation 
or burns.

• Have your power tool serviced by a qualifi ed 

repair person using only identical replacement 
parts. 

This will ensure that the safety of the power 

tool is maintained.
