the battery pack after use, avoid

placing the charger or battery pack

in a warm environment such as in

a metal shed, or an uninsulated

trailer.

GENERAL SAFETY

› DO NOT store or use the tool and

battery pack in locations where the

temperature may reach or exceed

40ºC (such as outside sheds or metal

buildings in summer).

› The charger is designed to operate

on standard household electrical

power (240 volts). Do not attempt

to use it on any other voltage! The

battery pack is not fully charged out

of the carton. First read the safety

instructions and then follow the

charging notes and procedures.

› The longest life and best

performance can be obtained if the

battery pack is charged when the air

temperature is between 18 - 24ºC.

Do not charge the battery pack in

an air temperature below 10ºC or

above 40ºC. This is important and will

prevent damage to the battery pack.

› Do not incinerate the battery pack

even if it is seriously damaged or is

completely worn out. The battery can

explode in a fire.

› Never attempt to open the battery

pack for any reason. If the plastic

housing of the battery pack breaks or

cracks, immediately discontinue use

and do not recharge.

Save these instructions and other

documents supplied with this tool for

future reference.

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

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.

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-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.

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) BATTERY TOOL USE AND CARE

a) 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.

b) Use power tools only with

specifically designated battery. Use

of any other battery packs may create

a risk of injury and fire.

c) When the battery 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.

d) 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

ADDITIONAL SAFETY RULES

FOR IMPACT WRENCHES

a) Hold power tool by insulated

gripping surfaces, when performing

an operation where the fastener

may contact hidden wiring or its

own cord. Fasteners contacting a

“live” wire may make exposed metal

parts of the power tool “live” and

could give the operator an electric

shock.

b) Do not use the tool in wet or damp

conditions.

c) Wear ear protectors when in use.

Exposure to noise can cause

hearing loss.

d) Check the socket carefully for

wear, cracks or damage before

installation.

e) Hold the tool firmly.

f) The proper fastening torque may

differ depending upon the kind or

size of the bolt. Check the torque

with a torque wrench.

This appliance is not intended for

use by persons (including children)

with reduced physical, sensory

or mental capabilities, or lack of

experience and knowledge, unless

they have been given supervision or

instruction concerning use of the

appliance by a person responsible for

their safety.

Children should be supervised to

ensure that they don’t play with the

appliance.

Recommendations for the use of a

residual current device with a rated

residual current of 30mA or less:

› Wear a hard hat (safety helmet),

safety glasses and/or face shield. It

is also highly recommended that you

wear a dust mask, ear protection and

padded gloves.

› Secure the work piece. A work piece

clamped with clamping devices or

in a vice, is held more secure than

by hand.

› One-handed operation can be

hazardous. It is recommended you

hold the unit firmly with both hands

when operating the tool.

› After installing the wrench socket,

pull lightly on the socket to make sure

that it does not come loose. If the

socket is not installed properly, it can

come loose during use, which can be

dangerous.

› Hold the power tool with a firm grip.

High reaction torque can briefly occur

a qualified repair person using only

identical replacement parts. This will

ensure that the safety of the power

tool is maintained.

b) If the supply cord is damaged,

it must be replaced by the

manufacturer, its service agent or

similarly qualified persons in order to

avoid a hazard.

LITHIUM-ION BATTERY &

CHARGER SAFETY

OVER CHARGING PROTECTION

This feature ensures that the battery is

never overcharged. When the battery

has reached its full charge capacity

the charger will shut off protecting the

internal components of the battery from

being damaged. An internal component

of the battery pack is an over discharge

protector. This feature will stop the

battery from discharging beyond the

recommended lowest safety voltage.

OVER DISCHARGE PROTECTION

An internal component of the battery

pack is an over discharge protector.

This feature will stop the battery from

discharging beyond the recommended

lowest safety voltage.

OVER HEAT PROTECTION

The battery has an internal Thermister

cut off sensor which will cease the

charging cycle if the battery becomes

hot during the charging process. This

Thermister sensor will also stop the

battery from operating should the

battery become too hot during the

operation of the tool. This can happen

when the tool is overloaded or being

used for extended periods of time.

Up to 30min in cooling time may

be required depending on ambient

temperature and operation being

performed.

while tightening and loosening nuts

and bolts.

› Check that any socket to be used

is not cracked or broken. Broken or

cracked sockets are dangerous.

› If the ring securing the socket is

damaged, the socket may come off

during use causing personal injury.

› The torque delivered by the impact

wrench depends on how long it is

applied, the size of socket and other

factors such as the state of the battery

charge.

› Use a torque wrench to check that

the bolt has been tightened to the

appropriate level of torque.

› Stop the impact wrench before

changing the direction of rotation.

Always release the trigger switch and

wait for the impact wrench to stop

before switching the direction of

rotation.
