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. 12)
(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.
(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.
1. Mounting
CAUTION:
Be sure to turn power OFF and disconnect the plug
from the receptacle.
(1) Mount the core bit to the core bit shank. (Fig. 13)
Lubricate the thread of the core bit shank to
facilitate disassembly.
(2) Mount the core bit shank to the Rotary Hammer.
(Fig. 14)
(3) Insert the center pin into the guide plate until it
stops.
(4) Engage the guide plate with the core bit, and turn
the guide plate to left or right so that it does not
fall even if it faces downward. (Fig. 15)
