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

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 drill bit, pull

lightly on the bit to make sure that it

does not come loose. If the bit is not

installed properly, it can come loose

during use, which can be dangerous.

› Use a bit that is appropriate for the

application.

› Hold the power tool with a firm grip.

High reaction torque can briefly occur.

› Check that any bit to be used is not

cracked or broken. Broken or cracked

bits are dangerous.

› If the ring securing the bit is

damaged, the socket may come off

during use causing personal injury.

› The torque delivered by the hammer

drill depends on how long it is

applied, the size of bit and other

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.

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

charging process. This 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.

OVER CURRENT PROTECTION

Should the battery be overloaded

and the maximum current draw be

exceeded the battery will temporarily

stop working to protect the internal

components. The battery will resume

to normal operation once the excessive

current draw has returned to normal

safe level. This may take a few seconds.

SHORT CIRCUIT PROTECTION

If the battery pack was to short circuit

the short circuit protector would

immediately stop the battery pack

from operating. This will ensure that

no further internal components of the

battery or the tools are damaged.
