Using Drill Chuck, Chuck Adaptor; How To Use The Core Bit - Hitachi Koki DH 40MR Instructions De Sécurité Et Mode D'emploi

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 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.
