PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
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, the power tool
will start operating immediately, which could cause
a serious accident.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.

5. Installation of dust cup or dust collector (B)
(Optional accessories) (Fig. 2, Fig. 3)
When using a hammer drill for upward drilling
operations attach a dust cup or 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. 2.
When using a bit which has big diameter, enlarge
the center hole of the dust cup with this rotary
hammer.
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. 3)
CAUTION:
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.
Insert dust collector (B) completely into the chuck
part of the main unit.
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
the 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
(B) cannot touch the concrete surface but rotates.
Therefore please use dust collector (B) by attaching
to drill bits which have 166 mm, 160 mm, and 110
mm overall length.
Dump particles after every two or three holes when
drilling.
