Do not use them for wood or metal drilling work. ⅜ Insert dust collector (B) completely into the chuck part of the main unit. ⅜ 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 but rotates. 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.) 11
