IMPORTANT SAFETY INFORMATION

Read and understand all of the safety precautions, warnings and operating instructions in the Instruction Manual

before operating or maintaining this power tool.

Most accidents that result from power tool operation and maintenance are caused by the failure to observe basic

safety rules or precautions. An accident can often be avoided by recognizing a potentially hazardous situation

before it occurs, and by observing appropriate safety procedures.

Basic safety precautions are outlined in the “SAFETY” section of this Instruction Manual and in the sections which

contain the operation and maintenance instructions.

Hazards that must be avoided to prevent bodily injury or machine damage are identified by WARNINGS on the

power tool and in this Instruction Manual.

NEVER use this power tool in a manner that has not been specifically recommended by HITACHI.

MEANINGS OF SIGNAL WORDS

WARNING indicates a potentially hazardous situations which, if ignored, could result in death or serious injury.

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, fire 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

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 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.

01Eng_DH24PF3_US-1 9/6/12, 15:433

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 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) Service

a) Have your power tool serviced by a qualified

repair person using only identical

replacement parts.

This will ensure that the safety of the power

tool is maintained.

DOUBLE INSULATION FOR SAFER

OPERATION

To ensure safer operation of this power tool, HITACHI

has adopted a double insulation design. “Double

insulation” means that two physically separated

insulation systems have been used to insulate the

electrically conductive materials connected to the power

supply from the outer frame handled by the operator.

Therefore, either the symbol “ ” or the words “Double

insulation” appear on the power tool or on the

nameplate.

Although this system has no external grounding, you

must still follow the normal electrical safety precautions

given in this Instruction Manual, including not using the

power tool in wet environments.

To keep the double insulation system effective, follow

these precautions:

䡬

Only HITACHI AUTHORIZED SERVICE CENTER

should disassemble or assemble this power tool,

and only genuine HITACHI replacement parts

should be installed.

䡬

Clean the exterior of the power tool only with a

soft cloth moistened with soapy water, and dry

thoroughly.

Never use solvents, gasoline or thinners on plastic

components; otherwise the plastic may dissolve.

CAUTION:

䡬 The dust cup and dust collector (B) are for exclusive use of concrete drilling

work. Do not use them for wood or metal drilling work.

䡬 Insert dust collector (B) completely into the chuck part of the main unit.

䡬 When turning the rotary hammer on while dust collector (B) is detached from a

concrete surface, dust collector (B) will rotate together with the drill bit. Make

sure to turn on the switch after pressing dust cup on the concrete surface. (When

using dust collector (B) attached to a drill bit that has more than 7-15/32" (190

mm) of overall length, dust collector (B) cannot touch the concrete surface and

will rotate. Therefore please use dust collector (B) by attaching to drill bits which

have 6-17/32" (166 mm), 6-19/64" (160 mm) and 4-21/64" (110 mm) overall length.

䡬 Dump particles after every two or three holes when drilling.

䡬 Please replace the drill bit after removing dust collector (B).

8. Selecting the driver bit

diameter is employed to drive in the screws.

9. Confirm the direction of bit rotation

(Fig. 6)

The bit rotates clockwise (viewed from

the rear side) by pushing the R-side of

the push button. The L-side of the push

button is pushed to turn the bit

counterclockwise.

HOW TO USE

CAUTION:

䡬 To prevent accidents, make sure to turn the switch off and disconnect the plug

from the receptacle when the drill pits and other various parts are installed or

removed. The power switch should also be turned off during a work break and

after work.

1. Switch operation

䡬 The rotation speed of the drill bit can be controlled steplessly by varying the

amount that the trigger switch is pulled. Speed is low when the trigger switch is

pulled slightly and increases as the switch is pulled more. To turn the switch OFF,

release the trigger switch to its original position. However, the switch

trigger can only be pulled in halfway during reverse and rotates at half the speed

of forward operation.

䡬 Pulling the trigger and pushing the stopper, it keeps the switched-on condition

which is convenient for continuous running. When switching off, the stopper can

be disconnected by pulling the trigger again. The switch stopper is unusable

during reverse.

the change lever to

mark. (Fig. 7)

(1) Mount the drill bit.

(2) Pull the trigger switch after applying the

drill bit tip to the drilling position (Fig. 8)

(3) Pushing the rotary hammer forcibly is

not necessary at all. Pushing slightly so

that drill dust comes out gradually is

just sufficient.

CAUTION:

䡬 When the drill bit touches an iron reinforcing rod, the bit will stop immediately

and the rotary hammer will react to revolve. Therefore please grip the side handle

and handle tightly as shown in Fig. 8.

3. Rotation only

This rotary hammer can be set to

rotation only mode by pressing the

push button and turning the change

lever to

To drill a wood or metal material using

the separately sold drill chuck and chuck

adaptor, proceed as follows. Installing

drill chuck and chuck adaptor (Fig. 10):

(1) Attach the drill chuck to the chuck

adaptor.

(2) The part of the SDS-plus shank is the

same as the drill bit. Therefore, refer to

the item of “Mounting the drill bit” for

attaching it.

CAUTION:

䡬 Application of force more than necessary will not only reducing drilling

efficiency at all, but will deteriorate the tip edge of the drill bit and reduce the

service life of the rotary hammer in addition.

䡬 Drill bit may snap off while withdrawing the rotary hammer from the drilled

hole. For withdrawing, it is important to use a pushing motion.

䡬 Do not attempt to drill anchor holes or holes in concrete with the main unit in

the rotation only function.

䡬 Do not attempt to use the rotary hammer in the rotation and striking function

with the drill chuck and chuck adaptor attached. This would seriously shorten

the service life of every components of the machine.

4. When driving machine screws

(Fig. 11)

First, insert the bit into the socket in the

end of chuck adaptor (D).

Next, mount chuck adaptor (D) on the

main unit using procedures described

in 5 (1), (2), (3), put the tip of the bit in

the slots in the head of the screw, grasp

the main unit and tighten the screw.

CAUTION:

䡬 Exercise care not to excessively prolong driving time, otherwise, the screws

may be damaged by excessive force.

䡬 Apply the rotary hammer perpendicularly to the screw head when driving a

screw; otherwise, the screw head or bit will be damaged, or driving force will

not be fully transferred to the screw.

䡬 Do not attempt to use the rotary hammer in the rotation and striking function

with chuck adaptor (D) and bit attached.

5. When driving wood screws (Fig. 11)

(1) Selecting a suitable driver bit

Employ phillips screws, if possible, since the driver bit easily slips off the heads

of slotted-head screws.

(2) Driving in wood screws

䡬 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.

䡬 After rotating the rotary hammer at low speed for a while until a wood screw in

partly driven into the wood, squeeze the trigger more strongly to obtain the

optimum driving force.

CAUTION:

䡬 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.

depth the position of the hole will

establish. Bore after that removing the

center pin and the guide plate from core

bit.

(4) Application of excessive force will not only expedite the work, but will deteriorate

the tip edge of the drill bit, resulting in reduced service life of the rotary hammer.

CAUTION:

䡬 When removing the center pin and the guide plate, turn OFF the switch and

disconnect the plug form the receptacle.

3. Dismounting. (Fig. 22)

Remove the core bit shank from the

rotary hammer and strike the head of

the core bit shank strongly two or three

times with the hammer holding the

core bit, then the thread becomes loose

and the core bit can be removed.

MAINTENANCE AND INSPECTION

WARNING: Be sure to switch power OFF and disconnect the plug from the

receptacle during maintenance and inspection.

1. Inspecting the drill bits

Since use of a dull tool will cause motor malfunctioning and degraded efficiency,

replace the drill bit with a new one or resharpening without delay when abrasion

is noted.

2. Inspecting the screws

Regularly inspect all screws and ensure that they are properly tightened. Should

any of the screws be loosened, retighten them immediately.

WARNING: Using this rotary hammer with loosen screws is extremely

dangerous.

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. Inspecting the carbon brushes

For your continued safety and electrical shock protection, carbon brush inspection

and replacement on this tool should ONLY be performed by a Hitachi Authorized

Service Center.

5. How to replace grease

Low viscosity grease is applied to this rotary hammer so that it can be used for

a long period without replacing the grease. Please contact the nearest service

center for grease replacement when any grease is leaking from loosened screw.

Further use of the rotary hammer despite the grease shortage causes seizure to

reduce the service life.

CAUTION: A specific grease is used with this machine, therefore, the normal

performance of the machine may be badly affected by use of other

grease. Please be sure to let one of our service agents undertake

replacement of the grease.

6. Service and repairs

All quality power tools will eventually require servicing or replacement of parts

because of wear from normal use. To assure that only authorized replacement

parts will be used, all service and repairs must be performed by a Hitachi

Authorized Service Center, ONLY.
