When using a rotary hammer for upward drilling
operations attach a dust cup or a dust collector (B) to
collect dust or particles for easy operation.
Installing the dust cup
○
Use the dust cup by attaching to the drill bit as shown in
Fig. 8.
When using a bit which has big diameter, enlarge the
center hole of the dust cup with this rotary hammer.
Installing dust collector (B)
○
When using dust collector (B), insert dust collector (B)
from the tip of the bit by aligning it to the groove on the
grip. (Fig. 9)
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.
