(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
fi nished. 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
To prevent accidents, make sure to turn the
switch off and pull out the battery.
(1) Mount the core bit to the core bit shank. (Fig. 24)
Lubricate the thread of the core bit shank to facilitate
disassembly.

(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. 26)

2. How to bore (Fig. 27)
(1) Install the battery.
(2) A spring is installed in the center pin. Push it lightly
to the wall or the fl oor straight. Connect all over the
surface of the core bit tip and start operating.
(3) When boring about 3/16" (5 mm) in depth the position
of the hole will establish. Bore after that removing the
center pin and the guide plate from core bit.
(4) Application of excessive force will not only expedite
the work, but will deteriorate the tip edge of the drill bit,
resulting in reduced service life of the rotary hammer.
