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 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 166 mm, 160 mm,
and 110 mm overall length.
Dump particles after every two or three holes
when drilling.
Please replace the drill bit after removing dust
