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. 1 l-b)
The motor does not rotate if the push button is set
to the center position.
(Fig. 1%~)

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 be drilled varies according to the 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.

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.
