Hitachi DH 36DBL Handling Instructions Manual page 42

English
(1) Installation
After inserting the drill bit in the drill chuck holder, hold fi rmly the ring by hand and tighten
the sleeve by turning it clockwise (in the direction of "A")
If loosened in use, tighten strongly the sleeve. The harder you tighten the sleeve, the
stronger the gripping force becomes.
(2) Removal
Hold fi rmly the ring by hand and loosen the sleeve by turning it counterclockwise in the
direction of ("B").
CAUTION
○ Application of force more than necessary will not only expedite the work, but will
deteriorate the tip edge of the drill bit and reduce the service life of the rotary
hammer in addition.
○ Drill bits may snap off while withdrawing the rotary hammer from the drilled hole.
For withdrawing, it is important to use a pushing motion.
○ Do not attempt to drill anchor holes or holes in concrete with the machine set in the
rotation only function.
○ Do not attempt to use the rotary hammer in the rotation and striking function with
the drill chuck and chuck adapter attached. This would seriously shorten the
service life of every component of the machine.

First, insert the bit into the socket in the end of chuck
adapter (D).
Next, mount chuck adapter (D) on the main unit using
procedures described in 4 (1), (2), (3), put the tip of the bit

In the same manner as the drill bit is installed, install the
driver bit to the drill chuck holder. Apply the driver bit to
the groove of screw head and turn on the switch to tighten
the screw.
CAUTION
○ Exercise care not to excessively prolong driving time, otherwise, the screws may
be damaged by excessive force.
○ Apply the rotary hammer perpendicularly to the screw head when driving the
screw; otherwise, the screw head or bit will be damaged, or driving force will not be
fully transferred to the screw.
○ Do not attempt to use the rotary hammer in the rotation and striking function with
the chuck adapter and bit attached.
