To turn the switch OFF, pull the trigger switch again
to disengage the stopper, and 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.
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
● DH28PMY with the drill bit holder installed
(1) Mount the drill bit.
(2) Pull the trigger switch after applying the drill bit tip to
the drilling position (Fig. 9).
(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. 9.
3. Rotation only
This rotary hammer can be set to rotation only mode
by pressing the push button and turning the change
lever to the mark (Fig. 10).
To drill wood or metal material using the drill chuck
and chuck adapter (optional accessories), proceed as
follows.
● DH24PH, DH26PC, DH28PCY
Installing drill chuck and chuck adapter (Fig. 11).
(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.

<Installation/Removal of the drill bit (Fig.12)>
CAUTION
Prevent accidents, make sure to turn the switch off
and disconnect the plug from the receptacle.
When installing or removing the drill bit, be careful
not to hurt hands with the drill bit.
(1) Installation
After inserting the drill bit in the drill chuck holder,
hold firmly the ring by hand and tighten the sleeve by
turning it clockwise (in the direction of "← GRIP.ZU")
If loosened in use, tighten strongly the sleeve. The
harder you tighten the sleeve, the stronger the
gripping force becomes.
(2) Removal
Hold firmly the ring by hand and loosen the sleeve by
turning it counterclockwise in the direction of
("OPEN.AUF →").
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.

(2) Adjust the depth gauge position according to the
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 slots in the head of the screw,
grasp the main unit and tighten the screw.
In the same manner as the drill bit is installed, install
the driver bit to the drill chuck holder.
turn on the switch to tighten the screw.
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.
Employ plus-head screws, if possible, since the driver
bit easily slips off the heads of minus-head 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.
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.
This rotary hammer can be set to hammering only
mode by pressing the push button and turning the
change lever to the mark (Fig. 14).
