Installation of dust cup or dust collector (B) (Optional accessories) (Fig. 4, Fig. 5) When using a rotary hammer for upward drilling operations attach a dust cup or dust collector (B) to collect dust or particles for easy operation. ⅜ Installing the dust cup Use the dust cup by attaching to the drill bit a shown in Fig. 4. When using a bit which has big diameter, enlarge the center hole of the dust cup with this rotary hammer. CAUTION: ⅜ 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. 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 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. 9
