DRILLING AND DRIVING-IN OPERATIONS FOR ANCHORS
Use the optional accessories for anchors, such
as anchor adapter and taper shank adapter.

is used.
(1) Install the self-drilling anchor in the anchor
adapter (Fig. 6).
(2) Turn on the switch and drill a base hole with
the self-drilling anchor. (Fig. 7)
At the start of the hole-drilling slightly tilt the
hammer drill to determine the hole position.
(3) After cleaning out dust with a syringe, attach
the plug to the anchor tip and drive in the
anchor with a hand hammer.
(4) After driving in the anchor, use the drift key to
separate the anchor. (Fig. 8)
(5) By employing a hand hammer or pliers, snap
off the tapered portion of the anchor. (Fig. 9)
CAUTION:
Since the snapped-off tapered portion will fly
about, pay attention to the snapping direction.
