CAUTION:
When the warming up operation is performed,
hold the side handle and the main body securely
with both hands to maintain a secure grip and be
careful not to twist your body by the jammed drill
bit.
7. How to use the drill bit (taper shank) and the taper
shank adaptor.
(1) Install drill bit with taper shank in the taper shank
adaptor. (Fig. 12)
(2) Turn the power on and drill a base hole.
(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 with taper shank, insert a
cotter into the slot of the taper shank adaptor, place

USING DRILL CHUCK, CHUCK ADAPTOR
Note that this machine can be used at “rotation only” if
separately sold parts such as drill chuck and chuck
adaptor are attached. Use it with the selector lever
positioned at “rotation + hammering”.
WARNING:
During operation, be sure to grip the handle and
the side handle firmly to prevent your body from
swaying.
(1) Switching to “rotation + hammering”
For switching to “rotation + hammering”, follow
the same procedures mentioned in [3. When
drilling at “rotation + hammering”] in Page 8.
(2) Attaching chuck adaptor to drill chuck (Fig. 14)
(a) Attach the chuck adaptor to the drill chuck.
(b) The SDS max shank of the chuck adaptor is
equivalent to the drill bit. Therefore, follow
the same procedure as [6. How to install tool]
in Page 7 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.
