GENERAL SAFETY RULES

WARNING!

Read all instructions

Failure to follow all instructions listed below may result in

electric shock, ﬁ re and/or serious injury.

The term “power tool” in all of the warnings listed below

refers to your mains operated (corded) power tool or battery

operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

1) Work area

a) Keep work area clean and well lit.

Cluttered and 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.

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 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 oﬀ position before plugging in.

Carrying power tools with your ﬁ nger 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.

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.

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

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

tools’ 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 and

in the manner intended for the particular type

of power tool, taking into account the working

conditions and the work to be performed.

Use of the power tool for operations diﬀ erent from

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 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.

c) 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.

English

7

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 ﬁ re.

e) 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.

4. Disconnect the charger’s power cord from the

receptacle or cigarette lighter socket

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.

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

pilot lamp of the charger lights up green. In such a case,

ﬁ rst let the

battery cool, then start charging.

○ When the pilot lamp ﬂ ickers in red (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 UC18YML2 /

UC18YRSL / UC18YFSL / UC18YGSL 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.

○ Check the voltage of the in-car power source when

the pilot lamp ﬂ ickers in green (every 0.2 seconds)

continuously. (UC18YML2)

If the voltage is 12V or lower, it indicates that the car

battery has weakened and cannot be charged.

○ If the pilot lamp does not blink in red (every second) even

though the charger cord or cigarette lighter connecting

plug is connected to the power, it indicates that the

protection circuit of the charger may be activated.

Remove the cord or plug from the power and then

connect it

again after 30 seconds or so. If this does

not cause the pilot lamp to blink in red (every second),

please take the charger to the Hitachi Authorized Service

Center.

PRIOR TO OPERATION

Setting up and checking the work environment

Check if the work environment is suitable by following the

precautions.

HOW TO USE

1. Conﬁ rm the clutch dial position (See Fig. 5)

The three modes of screwdriver, drill and impact drill can

be switched by the position of the clutch dial in this unit.

(1) When using this unit as a screwdriver, line up the one of

the numbers “1, 3, 5 ... 22” on the clutch dial, or the dots,

with the triangle mark on the outer body.

(2) When using this unit as a drill, align the clutch dial drill

mark “

” with the triangle mark on the outer body.

(3) When using this unit as an impact drill, align the clutch

dial hammer mark “

” with the triangle mark on the outer

body.

CAUTION

○ The clutch dial cannot be set between the numerals “1, 3,

5 ... 22” or the dots.

○ Do not use with the clutch dial numeral between “22”

and the line at the middle of the drill mark. Doing so may

cause

damage (See Fig. 6).

2. Tightening torque adjustment

(1) Tightening torque

Tightening torque should correspond in its intensity to

the screw diameter. When too strong torque is used,

the screw head may be broken or be injured. Be sure

to adjust the clutch dial position according to the screw

diameter.

(2) Tightening torque indication

The

tightening torque diﬀ ers depending on the type of

screw and the material being tightened.

The unit indicates the tightening torque with the numbers

“1, 3, 5 ... 22” on the clutch dial, and the dots. The

tightening torque at position “1” is the weakest and the

torque is strongest

at the highest number (See Fig. 5).

(3) Adjusting the tightening torque

Rotate the clutch dial and line up the numbers “1, 3, 5 ...

22” on the clutch dial, or the dots, with the triangle mark

on the outer body. Adjust the clutch dial in the weak or the

strong

torque direction according to the torque you need.

CAUTION

○ The motor rotation may be locked to cease while the unit

is used as drill. While operating the driver drill, take care

not to lock the motor.

○ Too long hammering may cause the screw broken due to

excessive tightening.

3. Rotation to Impact changeover (See Fig. 5)

The “Rotation (Rotation

only)” and “Impact (Impact +

Rotation)” can be switched by aligning the drill mark

“

” or the hammer mark “ ” with the triangle mark on

the outer body.

○ To make holes in the metal, wood or plastic, switch to

“Rotation (Rotation only)”.

○ To make holes in bricks or concrete blocks, switch to

“Impact (Impact + Rotation)”.

––––––––––––

CAUTION

○ The selection examples shown in Table 5 should be

considered as general standard. As diﬀ erent types of

tightening screws and diﬀ erent materials to be tightened

are used in actual works proper adjustments are naturally

necessary.

○ When using the impact driver drill with a machine screw

at

HIGH (high speed), a screw may damage or a bit may

loose due to the tightening torque is too strong. Use the

driver drill at LOW (low speed) when using a machine

screw.

NOTE

○ The use of the battery in a cold condition (below 0 degree

Centigrade) can sometimes result in

the weakened

tightening torque and reduced amount of work. This,

however, is a temporary phenomenon, and returns to

normal when the battery warms up.

○ When using the unit as an impact drill, prolonged

operation of 5 minutes or more will result in internal heat

which may cause a repeated noise

other than the sound

normally emitted by the motor. This does not indicate a

malfunction.

Discontinuing use of the unit and allowing its internal

temperature to cool down will eliminate the noise.

For prolonged use, allow the unit to cool down

periodically.

7. Using the hook

The hook is used to hang up the power

tool to your waist

belt while working.

CAUTION

○ When using the hook, hang up the power tool ﬁ rmly not to

drop accidentally.

If the power tool is dropped, it may lead to an accident.

CAUTION

If an operation which is normally performed at the

“Rotation” setting is performed at “Impact” setting,

the

eﬀ ect of making holes does not only increase but it may

also damage the bit or other parts.

4. Change rotation speed

Operate the shift knob to change the rotational speed.

Move the shift knob in the direction of the arrow (See

Figs. 7 and 8).

When the shift knob is set to

“LOW”, the drill rotates at a

low speed. When set to “HIGH”, the drill rotates at a high

speed.

CAUTION

○ When changing the rotational speed with the shift knob,

conﬁ rm that the switch is oﬀ .

Changing the speed while the motor is rotating will

damage the gears.

○ When

setting the shift knob to “HIGH” (high speed)

and the position of the clutch dial is “17” or “22”, it may

happen that the clutch is not engaged and that the motor

is locked. In such a case, please set the shift knob to

“LOW” (low speed).

○ If the motor

is locked, immediately turn the power oﬀ . If

the motor is locked for a while, the motor or battery may

be burnt.

Be sure to turn the shift knob.

5. The scope and suggestions for uses

The usable scope for various types of work based on the

mechanical structure of this unit is shown in Table 4

.

English

13

○ When carrying the power tool with hooked to your waist

belt, do not ﬁ t any bit to the tip of power tool. If the sharp

bit such as drill is ﬁ tted to the power tool when carrying it

with hooked to your waist belt, you will be injured.

○ Install

securely the hook. Unless the hook is securely

installed, it may cause an injury while using.

(1) Removing the hook.

Remove the screws ﬁ xing the hook with Phillips screw

driver.(Fig. 9)

(2) Replacing the hook and tightening the screws.

Install securely the hook in the groove of power tool and

tighten the

screws to ﬁ x the hook ﬁ rmly. (Fig. 10)

8. Using the light

Pull the trigger switch to light up the light. The light keeps

on lighting while the trigger switch is being pulled. The

light goes out after releasing the trigger switch. (Fig. 11)

(The light automatically goes out 10 seconds after

releasing the

trigger switch.)

CAUTION

Do not expose directly your eye to the light by looking into

the light.

If your eye is continuously exposed to the light, your eye

will be hurt.

9. Mounting and dismounting of the bit

(1) Mounting the bit

Loosen the sleeve by turning it toward the left (in the

counterclockwise direction as viewed from the

front)

to open the clip on the keyless chuck. After inserting a

driver bit, etc., into the keyless drill chuck, and tighten

the sleeve by turning it toward the right (in the clockwise

direction as viewed from the front). (See Fig. 12)

○ If the sleeve becomes loose during operation, tighten it

further.

The tightening force becomes stronger when the sleeve

is tightened additionally.

(2) Dismounting the bit

Loosen the sleeve by turning it toward the left (in the

counterclockwise direction as viewed from the front), and

then take out the bit etc. (See Fig. 12)

NOTE

If the sleeve is tightened in a

state where the clip of the

keyless chuck is opened to a maximum limit, a click

noise may occur. This is the noise that occurs when the

loosening of the keyless chuck is prevented and is not a

malfunction.

CAUTION

When it is no longer possible to loosen the sleeve, use a

vise or similar instrument to secure the bit. Set the clutch

mode between 1 and 7 and then turn the sleeve to the

loose side (left side) while operating the clutch. It should

be easy now to loosen the sleeve.

10. Automatic spindle-lock mechanism

This unit has automatic spindle-lock mechanism for quick

bit changes.

11. Con

ﬁ rm that the battery is mounted correctly

12. Check the rotational direction

The bit rotates clockwise (viewed from the rear side) by

pushing the R-side of the selector button.

The L-side of the selector button is pushed to turn the bit

counterclockwise. (See Fig. 13) (The

and marks

are provided on the body.)

CAUTION

Always use this unit with clockwise rotation, when using it

as an impact drill.

13. Switch operation

○ When the trigger switch is depressed, the tool rotates.

When the trigger is released, the tool stops.

○ The rotational speed of the drill can be controlled by

varying the amount that the trigger switch is pulled.

Speed is low when the trigger switch is pulled slightly and

increases as the trigger switch is pulled more.

NOTE

A buzzing noise is produced when the motor is about to

rotate;

This is only a noise, not a machine failure.

14. For drilling into brick

Excessive pressing force never increases drilling speed.

It will not only damage the drill tip or reduce working

eﬃ ciency, but could also shorten the service life of

drill bit. Operate the impact driver drill within 10-15 kg

pressing force while

drilling into brick.

OPERATIONAL CAUTIONS

○ Resting the unit after continuous work

(1) The power tool is equipped with a temperature protection

circuit to protect the motor.

Continuous bolt-tightening work may cause the

temperature of the unit to rise, activating the temperature

protection circuit and automatically stopping operation.

If this happens, allow the power tool to cool before

resuming use.

(2) After

use for continuous tightening wood screw works,

rest the unit for 15 minutes or so when replacing the

battery. The temperature of the motor, switch, etc., will

rise if the work is started again immediately after battery

replacement, eventually resulting in burnout.

MAINTENANCE AND INSPECTION

1. Inspecting the tool

Since use of a dull tool will degrade eﬃ ciency and cause

possible motor malfunction, sharpen or replace the tool

as soon as abrasion is noted.

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. Cleaning on the outside

When the driver drill 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.

5. Storage

Store the driver drill in a place in which the temperature is

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

NOTE

Make sure that the battery is fully charged when stored

for

a long period (3 months or more). The battery with

smaller capacity may not be able to be charged when

used, if stored for a long period.

NOTE

Storing Lithium-ion Batteries

Make sure the lithium-ion batteries have been fully

charged before storing them.

Prolonged storage 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.

However, signiﬁ cantly reduced battery usage time may

be recovered by repeatedly charging and using the

batteries two to ﬁ ve times.

English

14

If the battery usage time is extremely short despite

repeated charging and use, consider the batteries dead

and purchase new batteries.
