CAUTION indicates a potentially hazardous situations which, if not avoided, may result in minor or moderate injury, or

may cause machine damage.

NOTE emphasizes essential information.

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.

4

English

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) 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

quali

ﬁ 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

After operation, pull out batteries from the charger

ﬁ rst, and then keep the batteries properly.

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.

●

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

connector. If there are no foreign objects,

it is probable that the battery or charger is

malfunctioning. Take it to your authorized

Service Center.

13

English

●

Since the built-in micro computer takes about

3 seconds to conﬁ rm that the battery being

charged with charger 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.

●

If the pilot lamp does not blink in red (every

second) even though the charger cord 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.

of the rotary hammer in addition.

●

Drill bits may snap oﬀ while withdrawing

the rotary hammer from the drilled hole. For

withdrawing, it is important to use a pushing

motion.

●

Do not attempt to drill anchor holes or holes in

concrete with the machine set in the rotation

only function.

●

Do not attempt to use the rotary hammer in

the rotation and striking function with the drill

chuck and chuck adapter attached. This would

seriously shorten the service life of every

component of the machine.

CAUTION

●

Exercise care not to excessively prolong driving

time, otherwise, the screws may be damaged by

excessive force.

●

Apply the rotary hammer perpendicularly to the

screw head when driving the screw; otherwise,

the screw head or bit will be damaged, or driving

force will not be fully transferred to the screw.

●

Do not attempt to use the rotary hammer in the

rotation and striking function with the chuck

adapter and bit attached.

5. When driving wood screws (Fig. 18)

(1) Selecting a suitable driver bit

Employ plus-head screws, if possible, since the driver

bit easily slips oﬀ the heads of minus-head screws.

(2) Driving in wood screws.

○

Prior to driving in wood screws, make pilot holes

suitable for them in the wooden board.

Apply the bit to the screw head grooves and gently

drive the screws into the holes.

○

After rotating the rotary hammer at low speed for a

while until the wood screw is partly driven into the

wood, squeeze the trigger more strongly to obtain the

optimum driving force.

CAUTION

Exercise care in preparing a pilot hole suitable

for the wood screw taking the hardness of the

wood into consideration. Should the hole be

excessively small or shallow, requiring much

power to drive the screw into it, the thread of the

wood screw may sometimes be damaged.

OPERATIONAL CAUTIONS

Resting the unit after continuous work

(1) The power tool is equipped with a temperature

protection circuit to protect the motor.

Continuous 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 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.

REACTIVE FORCE CONTROL

This product is equipped with a Reactive Force Control

(RFC) feature that reduces jerking of the tool body.

If the tool bit is suddenly overburdened, any jerking of the

tool body is reduced by activation of the slip clutch or by

stopping of the motor by the sensor built into the tool body.

If the motor is stopped because of overburdening

detection by the controller, this is indicated by blinking

of the remaining battery lamp while the switch is pulled.

(Fig. 25)

Because the RFC feature may not activate or its

performance may be insuﬃ cient depending on the

working environment and conditions, be careful not to

suddenly overburden the tool bit while operating.

●

Possible causes of sudden overburdening

1

Tool bit biting into material

2

Impact against nails, metal or other hard objects

3

Tasks involving prying or any excess application of

pressure, etc.

Also, other causes include any combination of the

aforementioned.

●

When the reactive force control (RFC) is triggered

When the RFC is triggered and the motor stops, turn

oﬀ the tool’s switch and remove the cause of the

overburdening before continuing operation.
