Hitachi Koki USA DH 24PM Power Hammer User Manual

English
Speed is low when the trigger switch is
pulled slightly and increases as the
switch is pulled more. To turn the switch
OFF, release the trigger switch to its
original position. However, the switch
trigger can only be pulled in halfway
during reverse and rotates at half the
speed of forward operation.
Pulling the trigger and pushing the
stopper, it keeps the switched-on
condition which is convenient for
continuous running. When switching off,
the stopper can be disconnected by
pulling the trigger again. The switch
stopper is unusable during reverse.
2. Rotation + Hammering
This rotary hammer can be set to rotation
and hammering mode by pressing the
push button and turning the change lever
to the
mark with the drill bit holder
installed. (Fig.9 )
(1) Mount the drill bit.
(2) Pull the trigger switch after applying the
drill bit tip to the drilling position (Fig. 10)
(3) Pushing the rotary hammer forcibly is not
necessary at all. Pushing slightly so that
drill dust comes out gradually is just
sufficient.
CAUTION:
When the drill bit touches an iron
reinforcing rod, the bit will stop
immediately and the rotary hammer will
react to revolve. Therefore please grip
the side handle and handle tightly as
shown in Fig. 10.
3. Rotation only
This rotation hammer can be set to
rotation only mode by pressing the push
button and turning the change lever to
the
mark with the drill chuck holder
installed. (Fig. 11)

WARNING:

careful not to hurt hands with the drill bit.

chuck holder, hold firmly the ring by hand
and tighten the sleeve by turning it

the stronger the gripping force becomes.

the sleeve by turning it counterclockwise
in the direction of (“OPEN.AUF ”)
