⅜ 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. 10)

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).

5. 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.

6. Confirm the direction of bit rotation (Fig. 11)

The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the
push button. (Fig. 11-a)
The L-side of the push button is pushed to turn the bit counterclockwise. (Fig. 11-b)
The motor does not rotate if the push button is set to the center position. (Fig. 11-c)
