7. Installation of dust cup or dust collector (B)
(Optional accessories) (Fig. 4, Fig. 5)
When using a rotary hammer 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 a shown
in Fig. 4.
When using a bit which has big diameter, enlarge
the center hole of the dust cup with this rotary
hammer.

Dust collector (B)
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
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.
Dump particles after every two or three holes when
drilling.
Please replace the drill bit after removing dust
collector (B).
8. 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.
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.
