the side handle fi rmly to prevent your body from
swaying.

(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.
