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)
