How To Use - HIKOKI DH 30PC2 Mode D'emploi

English
To operate the change lever, press the push button,
and release the lock of the change lever. Also, check
and make sure after operation that the push button
has returned and that the change lever has been
locked.
Switch the change lever without mistake. If it is
used at a position halfway, there is a fear that the
service life of the switching mechanism may be
shortened.
8. RCD
The use of a residual current device with a rated
residual current of 30mA or less at all times is
recommended.

HOW TO USE

CAUTION:
To prevent accidents, make sure to turn the switch off
and disconnect the plug from the receptacle when the
drill bits and other various parts are installed or removed.
The power switch should also be turned off during a
work break and after work.
1. Switch operation
The rotation speed of the drill bit can be controlled
steplessly by varying the amount that the trigger
switch is pulled. Speed is low when the trigger
switch is pulled slightly and increases as the switch
is pulled more.
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
Turn the grip slightly and confirm that the clutch
has been engaged with a click.
(1) Mount the drill bit.
(2) Pull the trigger switch after applying the drill bit
tip to the drilling position. (Fig. 4)
(3) Pushing the rotary hammer forcibly is not necessary
at all. Pushing slightly so that drill dust comes out
gradually is sufficient.
CAUTION:
When the drill bit touches construction iron bar, the
bit will stop immediately and the rotary hammer
will react to revolve. Therefore grip the side handle
and handle tightly as shown in Fig. 4.
3. Rotation only
This rotary hammer can be set to rotation only
mode by pussing the push button and turning the
change lever to the
Turn the grip slightly and confirm that the clutch
has been engaged with a click.
To drill wood or metal material using the drill chuck
and chuck adapter (optional accessories), proceed
as follows.
Installing drill chuck and chuck adapter: (Fig. 6)
(1) Attach the drill chuck to the chuck adapter.
(2) The part of the SDS-plus shank is the same as the
drill bit. Therefore, refer to the item of "Mounting
the drill bit" for attaching it.
CAUTIONS:
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.

mark. (Fig. 5)
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 hammering function with the drill chuck
and chuck adapter attached. This would seriously
shorten the service life of every component of the
machine.
4. When driving machine screws (Fig. 7)
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 slots in the head of the screw,
grasp the main unit and tighten the screw.
CAUTIONS:
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 hammering function with the chuck
adapter and bit attached.
5. When driving wood screws (Fig. 7)
(1) Selecting a suitable driver bit
Employ cross-recessed screws, if possible, since the
driver bit easily slips off the heads of slotted-head
screws.
(2) Driving in wood screws
Prior to driving in wood screws, make pilot holes
suitable for them in the wooden board. Apply the
bit to the screw head grooves and gently drive the
screws into the holes.
After rotating the rotary hammer at low speed for
a while until the wood screw is partly driven into
the wood, squeeze the trigger more strongly to
obtain the optimum driving force.
CAUTION:
Exercise care in preparing a pilot hole suitable for
the wood screw taking the hardness of the wood
into consideration. Should the hole be excessively
small or shallow, requiring much power to drive
the screw into it, the thread of the wood screw may
sometimes be damaged.
6. Hammering only
This rotary hammer can be set to hammering only
mode by pressing the push button and turning the
change lever to the
(1) Mount the bull point or cold chisel.
(2) Press the push button and set the change lever to
mark. (Fig. 9)
The rotation is released, turn the grip and adjust
the cold chisel to desired position. (Fig. 10)
(3) Turn the change lever to
Then bull point or cold chisel is locked.
7. Using the stopper (Fig. 11)
(1) Loosen the side handle, and insert the stopper into
the handle bolt hole.
(2) Adjust the stopper position according to the depth
of the hole and thighten the side handle securely.
