⅜ Installing dust collector (B)
When using dust collector (B), insert dust collec-
tor (B) from the tip of the bit by aligning it to the
groove on the grip (Fig. 10)
CAUTION:
⅜ The dust cup and dust collector (B) are for exclu-
sive 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 press-
ing dust cup on the concrete surface. (When us-
ing 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 sur-
face 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.
⅜ Dump particles after every two or three holes
when drilling.
⅜ Please replace the drill bit after removing dust
collector (B).
5. Selecting the driver bit
Screw heads or bits will be damaged unless a bit appropriate for the screw diameter is
employed to drive in the screws.
6. Confirm the direction of bit rotation (Fig. 11)
The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the re-
versing switch lever. The L-side of the lever is pushed to turn the bit counterclockwise.
