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
