APPLICATIONS
This demolition hammer should be applied to breaking
concrete, chipping off concrete, grooving, bar cutting and
driving piles in installation of piping and wiring, sanitary
facility installation, machinery installation, water supply
and drainage work, interior jobs, harbor facilities and
other civil engineering work.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the
nameplate of this demolition hammer.
2. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the
power switch is in the ON position, this demolition
hammer will start operating immediately, inviting
serious accident.
3. Extension cord
When the work area is remote from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Mounting an accessory, such as a bull point, a
cutter, etc.
(1) With the retainer directed backward, insert the
accessory shank point into the hole on the front
cover. (Fig. 1)
(2) Swing the retainer back into place so that it engages
the accessory shank point and prevents the
accessory, such as a bull point, a cutter, etc. from
coming all the way out of front cover. (Fig. 2)
NOTE
Use a manual hammer to open/close the retainer,
as it is too heavy to move by hand.
When removing the accessory, such as a bull point,
a cutter, etc., follow the above procedure in reverse
order.
5. Always hold the body handle and side handle of
this demolition hammer firmly.
Otherwise the counterforce produced may result in
inaccurate and even dangerous operation.
OPERATION
1. Pull the trigger switch after applying the tip of the
bit to the crushing position.
In some cases, it is necessary to punch the tip of
the bit against the crushing position forcibly in
order to begin the striking stroke.
This is not due to malfunction of the power tool.
It means that the safe guard mechanism against
no-load striking is working.

2. Operate this demolition hammer by utilizing its
own weight.
The performance will not be better even if it is
pressed or thrust forcibly against the work surface.
Hold this demolition hammer with a force just
sufficient to counteract the reaction.
CAUTION
Sometimes the power tool does not begin the
striking stroke even when the motor rotates because
the oil has become thick.
If the power tool is used at low temperatures or
if it is used after a long idle time, this demolition
hammer should be kept running in for about five
minutes in order to warm it up.
HOW TO REPLACE GREASE
This demolition hammer is full air-tight construction
to protect against dust and to prevent lubricant leakage.
Therefore, this demolition hammer can be used without
lubrication for long periods. Replace the grease as
described below.
Grease replacement period
After purchase, replace grease after every 6 months
of usage. Ask for grease replacement at the nearest
authorized service center.
MAINTENANCE AND INSPECTION
1. Inspecting this demolition hammer
Use of a dull accessory, such as a bull point, a
cutter, etc., will cause motor malfunctioning and
degraded efficiently. Replace with a new one without
delay when 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. Inspecting the retainer (Fig. 1, Fig. 2)
The retainer may become loose due to excessive
use. Always, pay attention to its proper functioning
to securely hold the accessory shank portion. If any
wear and tear is found, bring this demolition
hammer to an authorized service center for
maintenance service.
4. 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.
5. Inspecting the carbon brushes (Fig. 3)
The motor employs carbon brushes which are
consumable parts. When they become worn to or
near “wear limit”, it results in motor trouble. When
an auto-stop carbon brush is equipped, the motor
will stop automatically. At that time, replace both
carbon brushes with new ones which have the
same carbon brush Nos. shown in the figure 3. In
addition, always keep carbon brushes clean and
ensure that they slide freely within the brush holders.
6. Replacement procedure
Loosen the screw (Hexagon socket hd. bolt M5 ×
10) of the tail cover, then remove the tail cover
(Fig. 4). After removing the brush cap, the carbon
brush can be removed.
After replacing the carbon brush, tighten the brush
cap, then mount the tail cover securely.
NOTE
Due to HITACHI’s continuing program of research and
development, the specifications herein are subject to
change without prior notice.

Español
(2) Deslice el retenedor hasta su posición de forma que
enganche la punta del vástago del accesorio para evitar
que el accesorio (la punta maestra, la cuchilla, etc.) se
salga a través de la cubierta frontal. (Fig. 2)
NOTA
Para abrir y cerrar el retenedor, utilice un martillo,
ya que es demasiado pesado para moverlo
manualmente.
Para extraer el accesorio (por ejemplo, la punta
maestra, la cuchilla, etc.), siga el procedimiento
inverso.
5. Sujete siempre firmemente el asidero del cuerpo
y el asidero lateral del martillo.
De lo contrario, la contrafuerza producida podría
causar un funcionamiento impreciso e incluso
peligroso.
OPERACIÓN
1. Después de aplicar con fuerza la punta de la
herramienta contra la superficie de trabajo, apriete
el interruptor disparador para comenzar la percusión.
Esto no se debe a una avería de la herramienta
eléctrica.
Esto significa que está trabajando el mecanismo de
protección contra la percusión sin carga.
2. Emplee el martillo utilizando su propio peso.
El rendimiento no mejorará aunque presione con
mayor fuerza la heramienta contra la superficie de
trabajo.
Emplee la fuerza suficiente en el martillo para
controlar la reacción.
PRECAUCIÓN
Puede ser que algunas veces la herramienta eléctrica
no comience a percutir, aunque el motor esté en
funcionamiento, debido a que el aceite se ha vuelto
espeso.
Cuando utilice la herramienta eléctrica a bajas
temperaturas, o cuando no la haya utilizado durante
mucho tiempo, deje el martillo en funcionamiento
durante cinco minutos aproximadamente para que
se caliente.
CAMBIO DE GRASA
La construcción de este martillo completamente estanca,
para evitar que entre polvo y haya fugas de lubricante.
Por ello, el martillo puede usarse sin lubricante durante
largos períodos. Cuando haya que cambiar la grasa,
proceda como sigue:
Período de cambio de grasa
Tras la adquisición de la herramienta, cambie la grasa
cada 6 meses de uso. Consultar para ello al centro de
servicio autorizado.
MANTENIMIENTO E INSPECCION
1. Inspección del martillo
La utilización de un accesorio mellado (por ejemplo,
una punta maestra, una cuchilla, etc.) puede causar
la avería del motor y degradar la eficacia. Cuando
note abrasión, reemplácela lo antes posible por
otra nueva.
2. Inspección de los tornillosde montaje
Inspeccionar regularmente todos los tornillos de
montaje y asegurarse de que estén apretados
firmemente. Si cualquier tornillo estuviera suelto,
volver a apretarlo inmediatamente. El no hacer esto
provocaría un riesgo serio.
3. Inspección del retenedor (Fig. 1, Fig. 2)
Es posible que el retenedor se afloje debido a un
uso excesivo. Fíjese siempre si funciona
correctamente para sujetar bien el vástago del
accesorio. Si descubre algún desgaste o rotura,
lleve el martillo a un centro de servicio autorizado
para que lo reparen.
4. Mantenimiento del motor
La unidad de bobinado del motor es el verdadero
“corazón” de las herrantientas eléctricas.
Prestar el mayor cuidado a asegurarse de que el
bobinado no se dañe y/o se humedezca con aceite
o agua.
5. Inspección de las escobillas de carbón (Fig. 3)
El motor emplea escobillas de carbón que son
partes consumibles. Cuando se gasten o estén cerca
del “límite de uso”, causan problemas al motor.
Al equiparse la escobilla de carbón de parada
automática, el motor se detendrá automáticamente.
En ese momento hay que proceder a cambiar ambas
escobillas de carbón por las nuevas, que tienen los
mismos números de escobillas de carbón que se
muestran en la figura 3. Adicionalmente, debe
mantener siempre limpias las escobillas de carbón
y asegurarse de que se deslicen libremente dentro
de los portaescobillas.
6. Procedimiento de reemplazo
Afloje el tornillo (perno de cabeza hexagonal M5

6. Do not force the tool. It will do the job better and
safer at the rate for which it was intended.
7. Use the right tool. Do not force small tools or
attachments to do the job of a heavy duty tool.
Do not use tools for purposes not intended; for
example, do not use circular saw to cut tree limbs
or logs.
8. Dress properly. Do not wear loose clothing or
jewellery, they can be caught in moving parts.
Rubber gloves and non-skid footwear are recom-
mended when working outdoors. Wear protecting
hair covering to contain long hair.
9. Use eye protection. Also use face or dust mask
if the cutting operation is dusty.
10. Connect dust extraction equipment.
If devices are provided for the connection of dust
extraction and collection facilities ensure these
are connected and properly used.
11. Do not abuse the cord. Never carry the tool by
the cord or yank it to disconnect it from the
receptacle. Keep the cord away from heat, oil and
sharp edges.
12. Secure work. Use clamps or a vise to hold the
work. It is safer than using your hand and it frees
both hands to operate tool.
13. Do not overreach. Keep proper footing and bal-
ance at all times.
14. Maintain tools with care. Keep cutting tools sharp
and clean for better and safer performance. Fol-
low instructions for lubrication and changing

damaged, have it repaired by authorized service
center. Inspect extension cords periodically and
replace, if damaged. Keep handles dry, clean, and
free from oil and grease.
15. Disconnect tools. When not in use, before servic-
ing, and when changing accessories such as
blades, bits and cutters.
16. Remove adjusting keys and wrenches. Form the
habit of checking to see that keys and adjusting
wrenches are removed from the tool before turn-
ing it on.
17. Avoid unintentional starting. Do not carry a
plugged-in tool with a finger on the switch. Ensure
switch is off when plugging in.
18. Use outdoor extension leads. When tool is used
outdoors, use only extension cords intended for
outdoor use.
19. Stay alert. Watch what you are doing. Use com-
mon sense. Do not operate tool when you are
tired.
20. Check damaged parts. Before further use of the
tool, a guard or other part that is damaged should
be carefully checked to determine that it will
operate properly and perform its intended func-
tion. Check for alignment of moving parts, free
running of moving parts, breakage of parts,
mounting and any other conditions that may affect
its operation. A guard or other part that is dam-
aged should be properly repaired or replaced by
an authorized service center unless otherwise
indicated in this handling instructions. Have de-
fective switches replaced by an authorized service
center. Do not use the tool if the switch does not
turn it on and off.
