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 safety equipment. Always wear eye protection. Safety
equipment such as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions will reduce personal
injuries.

c) Avoid accidental starting. Ensure the switch is in the off­position before plugging in. Carrying power tools with your finger on

the switch or plugging in 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.

3

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 these devices can reduce dust-related hazards.

POWER TOOL USE AND CARE

4

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

BATTERY TOOL USE AND CARE
a) Ensure the switch is in the off position before inserting battery
pack. Inserting the battery pack into power tools that have the switch

on invites accidents.

b) Recharge only with the charger specified by the manufacturer.

A charger that is suitable for one type of battery pack may create a risk
of fire when used with another battery pack.

c) Use power tools only with specifically designated battery
packs. Use of any other battery packs may create a risk of injury and

fire.

d) When battery pack is not in use, keep it away from other metal
objects like paper clips, 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 fire.

e) Under abusive conditions, liquid may be ejected from the
battery; avoid contact. If contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally seek medical help.

Liquid ejected from the battery may cause irritation or burns.

6

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.
