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) 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 toolʼs 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.

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.

7

English

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.

PRECAUTION

Keep children and inﬁ rm persons away.

When not in use, tools should be stored out of reach of

children and inﬁ rm persons.

CORDLESS IMPACT WRENCH

SAFETY WARNINGS

4. Disconnect the charger’s power cord from the

receptacle.

5. Hold the charger ﬁ rmly and pull out the battery.

NOTE

Be sure to pull out the battery from the charger after use,

and then keep it.

Regarding electric discharge in case of new batteries,

etc.

As the internal chemical substance of new batteries and

batteries that have not been used for an extended period

is not activated, the electric discharge might be low when

using them the ﬁ rst and second time. This is a temporary

phenomenon, and normal time required for recharging

will be restored by recharging the batteries 2–3 times.

English

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

○ 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 charge indicator lamp of the charger lights

for 0.3 seconds, does not light for 0.3 seconds (oﬀ for

0.3 seconds). In such a case, ﬁ rst let the battery cool,

then start charging.

○ When the charge indicator lamp ﬂ ickers (at 0.2-second

intervals), check for and take out any foreign objects in

the charger’s battery connector. If there are no foreign

objects, it is probable that the battery or charger is

malfunctioning. Take it to your authorized Service

Center.

○ Since the built-in micro computer takes about

3 seconds to conﬁ rm that the battery being charged with

UC18YSL3 is taken out, wait for a minimum of 3 seconds

before reinserting it to continue charging. If the battery

is reinserted within 3 seconds, the battery may not be

properly charged.

MAINTENANCE AND INSPECTION

1. Inspecting the socket

A worn or deformed hex. or a square-holed socket will

not give an adequate tightness to the ﬁ tting between

the nut or anvil, consequently resulting in loss of

tightening torque. Pay attention to wear of a socket holes

periodically, and replace with a new one if needed.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that

they are properly tightened. Should any of the screws be

loose, retighten them immediately. Failure to do so could

result in serious hazard.

3. Maintenance of the motor

The motor unit winding is the very “heart” of the power

tool. Exercise due care to ensure the winding does not

become damaged and/or wet with oil or water.

4. Inspection of terminals (tool and battery)

Check to make sure that swarf and dust have not

collected on the terminals.

On occasion check prior, during and after operation.

CAUTION

Remove any swarf or dust which may have collected on

the terminals.

Failure to do so may result in malfunction.

5. Cleaning on the outside

When the tool is stained, wipe with a soft dry cloth or

a cloth moistened with soapy water. Do not use chloric

solvents, gasoline or paint thinner, for they melt plastics.

6. Storage

Store the power tool in a place in which the temperature

is less than 40°C and out of reach of children.

NOTE

Storing lithium-ion batteries.

Make sure the lithium-ion batteries have been fully

charged before storing them.

Prolonged storage (3 months or more) of batteries with

a low charge may result in performance deterioration,

signiﬁ cantly reducing battery usage time or rendering

the batteries incapable of holding a charge.

English

However, signiﬁ cantly reduced battery usage time may

be recovered by repeatedly charging and using the

batteries two to ﬁ ve times.

If the battery usage time is extremely short despite

repeated charging and use, consider the batteries dead

and purchase new batteries.

CAUTION

In the operation and maintenance of power tools, the

safety regulations and standards prescribed in each

country must be observed.

Important notice on the batteries for the HiKOKI
