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 fi rmly 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 9.
(2) Attaching chuck adaptor to drill chuck (Fig. 16)
(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
effi ciency and shortened life of this machine.
(b) A drill can snap sometimes when drilling is
almost finished. It is important to relax your
thrusting pressure when drilling is nearing the
end.

HOW TO USE THE CORE BIT

When boring penetrating large hole use the core bit. At
that time use with the center pin and the core bit shank
provided as optional accessories.
