(1) Switching to “rotation + hammering”

procedures mentioned in [3. When
drilling at “rotation + hammering”] in
Page 12.
(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 10 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. 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.
