CAUTIONS
If the battery has been heated (due to sunlight, etc.1
right after operation, the charger’s pilot lamp may
not light in red. In such a case, first let the battery
cool, then start charging.
When the pilot lamp flikers in red (at 0.2~second
intervals), check for and take out any foreign objects
in the charger’s battery installation hole. If there are
no foreign objects, it is probable that the battery
or charger is malfunctioning. Take it to your au-
thorized Service Center.
Do not use UC24YF to charge the battery at a
temperature lower than O’C. Rapid charging at low
temperature will shorten the battery life. Due to
this, it may take a maximum of 60 minutes to
charge EB24B.
Selecting the driver bit
Screw heads or bits will be damaged unless a bit
appropriate for the screw diameter is employed to
drive in the screws.
Confirm the direction of bit rotation (Fig. II)
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the push button. (Fig.
ll-a)
The L-side of the push button is pushed to turn the
bit counterclockwise. (Fig. 1l-b)
The motor does not rotate if the push button is set
to the center position. (Fig. 1%~)
Continuous drilling
The number of holes that can be drilled in concrete
after one recharge is shown in Table 3.

Mounting the drill bit (Fig. 6)
To attach a drill bit (SDS-plus shank), fully pull the
grip in the direction of the arrow as shown in Fig.
6 and insert the drill bit as far as it will go while
rotating.
By releasing the grip, the drill bit will be secured.
To remove the drill bit, fully pull the grip in the
direction of the arrow and pull out the drill bit.
Confirm that the battery is mounted correctly.
Installation of dust cup or dust collector (B) (Op-
tional accessories) (Fig, 8, Fig. 9)
When using a hammer drill for upward drilling
operations attach a dust cup or a dust collector (B)
to collect dust or particles for easy operation.
Installing the dust cup
Use the dust cup by attaching to the drill bit as
shown in Fig. 8.
When using a bit which has big diameter, enlarge
the center hole of the dust cup with this hammer
drill.
Installing dust collector (B)
When using dust collector (B), insert dust collector
(B) from the tip of the bit by aligning it to the
groove on the grip. (Fig. 9)
CAUTION:
0 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.
0 Insert dust collector (B) completely into the chuck
part of the main unit.
0 When turning the hammer drill 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 190 mm of overall length, dust collector (BI
cannot touch the concrete surface and will rotate.
Therefore, please use dust collector (BI by attaching
to drill bits which have I66 mm, 160 mm, and 110
mm overall length.
0 Dump particles after every two or three holes when
drilling.
0 Please replace the drill bit after removing dust
collector (B).

These data are for the referential values. The number of
holes that can bedrilled varies according tothe sharpness
of the used bit or the conditions of the concrete being
drilled.
CAUTION
When using this unit continuously, the unit may overheat,
leading to damage in the motor and switch.
Please leave it without using it for approximately 15
minutes.
HOW TO USE
1. Switch operation
2.
(11
(21
(31
The rotational speed of the drill bit can be con-
trolled 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.
Rotation + Striking
Align the ”b ” mark with the “?’ mark by rotating
the change lever to set the “Rotation + Striking”
mode. (Fig. IO)
Mount the drill bit.
Rdl the trigger switch after applying the drill bit
tip to the drilling position. (Fig. 7)
Pushing the hammer drill forcibly is not necessary
at all. Pushing slightly so that drill dust comes out
gradually is just sufficient.
CAUTION
When the drill bit touches construction iron bar, the
bit will stop immediately and the hammer drill will
react to revolve. Therefore please grip the side
handle and handle tightly as shown in Fig. 7.
Rotation only
Align the ”b ” mark with the “=# mark by rotating
the change lever to set the “Rotation only” mode.
(Fig. IO)

.
English
-
To drill a wood or metal material using the optional
drill chuck and chuck adapter, proceed as follows.
Installing drill chuck and chuck adapter: (Fig. 12)
Attach the drill chuck to the chuck adaptor.
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.
CAUTIONS
Application of force more than necessary will
not only expedite work at all, but will deteriorate
the tip edge of the drill bit and reduce the
service life of the hammer drill in addition.
Drill bit may snap off while withdrawing the
hammer drill from the drilled hole. For with-
drawing, it is important to use a pushing motion.
Do not attempt to use the hammer drill in the
rotation and striking mode with the drill chuck
and chuck adapter attached. This would seri-
ously shorten the service life of every compo-
nent of the machine.
When driving wood screws (Fig. 14)
Selecting a suitable driver bit
Employ plus-head screws, if possible, since the
driver bit easily slips off the heads of slotted-head
screws.
Tightening wood screws
Prior to tightening 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 in the holes.
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.
Using depth gauge (Fig. 13)
Loosen the knob on the side handle, and insert the
stopper into the mounting hole on the side handle.
Adjust the depth gauge position according to the
depth of the hole and tighten the knob bolt se-
curely.
How to use the drill bit (taper shank) and the taper
shank adapter
Mount the taper shank adapter to the hammer drill.
(Fig. 15)
Mount the drill bit (taper shank) to the taper shank
adapter. (Fig. 15)
Turn the switch ON, and drill a hole to prescribed
depth.
TO remove the drill bit (taper shank), insert the
cotter into the slot of the taper shank adapter and
strike the head of the cotter with a hammer sup-
porting on the rest. (Fig. 16)
LUBRICATION
Low viscosity grease is applied to this hammer drill 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 form
loosened screw.
Further use of the hammer drill despite the grease short-
age causes damage to reduce the service life.
11
CAUTION
A specific grease (FG6A) is used with this machine,
therefore, the normal performance of the machine may
be badly affected by use of different grease. Please be
sure to let one of our service centers to undertake replace-
ment of the grease.
MAINTENANCE AND INSPECTION
Inspecting the tool
Since use of a dull tool will degrade efficiency and
cause possible motor malfunction, sharpen or re-
place the tool as soon as abrasion is noted.
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. Fail-
ure to do so could result in serious hazard.
Cleaning on the outside
When the power 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,
as they melt plastics.
Storage
Store the power tool in a place in which the tem-
perature is lessthan 40°C and out of reach of children.
NOTE
Due to HITACHI’s continuing program of research and
development, the specifications herein are subject to
change without prior notice.
IMPORTANT
Correct connections of the plug
The wires of the mains lead are coloured in accordance
with the following code:
Blue: -Neutral
Brown: -Live
As the colours of the wires in the mains lead of this tool
may not correspond with the coloured markings identify-
ing the terminals in your plug proceed as follows:
The wire coloured blue must beconnected tothe terminal
