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 residual current device (RCD) protected supply.

Use of an RCD 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-

2

English

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 energising 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 jewellery.

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

Additional safety instructions for drills

• Wear ear protectors. Exposure to noise can cause hearing
loss.

• Use auxiliary handles supplied with the tool. Loss of control
can cause personal injury.

• Hold 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 shock the operator.
