DRILLING AND DRIVING-IN OPERATIONS
FOR ANCHORS
1. When a taper shank adapter is used. (Fig. 11)
(1) Install drill bit with taper shank in the taper shank
adapter.
(2) Turn the power on and drill a base hole to the depth
sounded by indicating groove on the drill bit.
(3) After cleaning out dust with a syringe, attach the
plug to the anchor tip and drive in the anchor with
a manual hammer.
(4) To remove the drill bit (taper shank), insert the
cotter into the slot of the taper shank adapter and
strike the head of the cotter with a manual hammer
supporting on a rest. (Fig. 12)
USING DRILL CHUCK, CHUCK ADAPTER
Note that this machine can be used at "rotation only"
if separately sold parts such as drill chuck and chuck
adapter are attached.
positioned at "rotation + striking".
CAUTION:
During operation, be sure to grip the handle and
the side handle firmly to prevent your body from
swaying.
(1) Switching to "rotation + striking"
For switching to "rotation + striking", follow the
same procedures mentioned in [3. When drilling
at "rotation + striking"].
(2) Attaching chuck adapter to drill chuck (Fig. 13)
(a) Attach the chuck adapter to the drill chuck.
(b) The SDS max shank of the chuck adapter is
equivalent to the drill bit. Therefore, follow the
same procedure as [How to install tool] for
attaching and detaching.
(3) Drilling
(a) Even if you apply more-than-required pressure
to the machine body, drilling can never be
performed as quickly as you expect. Applying
more force or pressure to the machine body
than what is needed, on the contrary, damages
the drill tip, resulting in the declined working
efficiency and shortened life of this machine.
(b) A drill can snap sometimes when drilling is
almost finished.

end.
HOW TO HANDLE A CORE BIT
When a core bit is used, large diameter holes and blind
holes can be drilled. In this case, use optional
accessories for core bits (such as a center pin and core
bit shank) for more efficient operation.
1. Mounting
CAUTION
Prior to mounting a core bit, always disconnect the
plug from the power supply receptacle.
(1) Mount the core bit on the core bit shank. (Fig. 14)
Before that, feed oil to the screw portion of core
bit shank for easy dismounting.
(2) Mount the core bit shank on the main body in the
same manner as in mounting the drill bit and the
bull point. (Fig. 15)
