SAFETY

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, 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.

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

ﬂ ammable 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.

Unmodiﬁ ed 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 inﬂ uence 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.

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 ﬁ nger 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

English

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 aﬀ ect 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 diﬀ erent

from those intended could result in a hazardous

situation.

5) Battery tool use and care

a) 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.

b) Use power tools only with speciﬁ cally

designated battery packs.

Use of any other battery packs may create a risk

of injury and ﬁ re.

c) 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 ﬁ re.

d) Under abusive conditions, liquid may be

ejected 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.

6) Service

a) 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.

– WARNING –

To reduce the risk of injury, user must read

instruction manual.

NOTE

The charging time may vary according to temperature

and power source voltage.

4. Disconnect battery charger from the receptacle.

CAUTION

Do not pull the plug out of the receptacle by

pulling on the cord.

Make sure to grasp the plug when removing from

receptacle to avoid damaging cord.

5. Remove the battery from the battery charger.

Supporting the battery charger with hand, pull out the

battery from the battery charger.

How to make the batteries perform longer

(1) Recharge the batteries before they become

completely exhausted.

When you feel that the power of the tool becomes

weaker, stop using the tool and recharge its battery.

If you continue to use the tool and exhaust the electric

current, the battery may be damaged and its life will

become shorter.

(2) Avoid recharging at high temperatures.

A rechargeable battery will be hot immediately after

use. If such a battery is recharged immediately after

use, its internal chemical substance will deteriorate,

and the battery life will be shortened. Leave the

battery and recharge it after it has cooled for a while.

CAUTION

●

When the battery charger has been continuosly

used, the battery charger will be heated, thus

constituting the cause of the failures. Once the

charging has been completed, give 15 minutes

rest until the next charging.

●

If the battery is charged while it is heated

because it has been left for a long time in a

location subject to direct sunlight or because

the battery has just been used, the pilot lamp of

the charger lights for 1 second, does not light for

0.5 seconds (oﬀ for 0.5 seconds). In such a case,

ﬁ rst let the battery cool, then start charging.

17

English

●

When the pilot lamp ﬂ ikers rapidly in red (at

0.2–second intervals), check for and take out

any foreign objects in the charger’s battery

installation hole. If there are no foreign objects,

it is probable that the battery or charger is

malfunctioning. Take it to your authorized

Service Center.

BEFORE OPERATION

Read section titled “SAFETY” (pages 3–10).

Make sure of the followings before operation.

PREPARING THE BATTERY

Read section titled “SAFETY, IMPORTANT SAFETY

INSTRUCTIONS FOR BATTERY CHARGER” (page 7).
