How To Use - HIKOKI DH 14DSL Instrucciones De Manejo

When using a rotary hammer for upward drilling
operations attach a dust cup or a dust collector (B)
to collect dust or particles for easy operation.
Installing the dust cup
Use the dust cup by attaching to the drill bit as
shown in Fig. 7.
When using a bit which has big diameter, enlarge
the center hole of the dust cup with this rotary
hammer.
Installing dust collector (B)
When using dust collector (B), insert dust collector
(B) from the tip of the bit by aligning it to the
groove on the grip. (Fig. 8)
CAUTION
The dust cup and dust collector (B) are for exclusive
use of concrete drilling work. Do not use them for
wood or metal drilling work.
Insert dust collector (B) completely into the chuck
part of the main unit.
When turning the rotary hammer on while dust
collector (B) is detached from a concrete surface,
dust collector (B) will rotate together with the drill
bit. Make sure to turn on the switch after pressing
dust cup on the concrete surface. When using dust
collector (B) attached to a drill bit that has more
than 190 mm of overall length, dust collector (B)
cannot touch the concrete surface and will rotate.
Therefore, please use dust collector (B) by attaching
to drill bits which have 166 mm, 160 mm, and 110
mm overall length.
Dump particles after every two or three holes when
drilling.
Please replace the drill bit after removing dust
collector (B).
4. Selecting the driver bit
Screw heads or bits will be damaged unless a bit
appropriate for the screw diameter is employed to
drive in the screws.
5. Confirm the direction of bit rotation (Fig. 9)
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the push button.
The L-side of the push button is pushed to turn the
bit counterclockwise. (See Fig. 9) (The
marks are provided on the body.)
CAUTION
The push button cannot be switched while the
power tool is turning. To switch the push button,
stop the power tool, then set the push button.
6. Continuous drilling
The number of holes that can be drilled in concrete
after one recharge is shown in Table 4.

These data are for the referential values. The number of
holes that can be drilled varies according to the sharpness
of the used bit or the conditions of the concrete being
drilled.
CAUTION
When using this unit continuously, the unit may
overheat, leading to damage in the motor and switch.
Please leave it without using it for approximately
15 minutes.

HOW TO USE

1. Switch operation
When the switch trigger is depressed, the tool
rotates. When the switch trigger is released, the tool
stops.
The rotational speed of the rotary hammer can be
controlled by varying the amount that the switch
trigger is pulled. Speed is low when the switch
trigger is pulled slightly and increases as the switch
trigger is pulled more.
When releasing the switch trigger, the brake will
be applied for immediate stopping.
2. Rotation + Hammering
Turn the change lever fully in the direction of the
" " mark to set "rotation + hammering".
(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 construction iron bar, 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. 11.
3. Rotation only
Turn the change lever fully in the direction of the
" " mark to set "rotation only". (Fig. 10)
To drill a wood or metal material using the optional
drill chuck and chuck adapter, proceed as follows.
R
Installing drill chuck and chuck adapter: (Fig. 12)
(1) Attach the drill chuck to the chuck adaptor.
(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.
CAUTION
Application of force more than necessary will
not only expedite work at all, but will deteriorate
the tip edge of the drill bit and reduce the
service life of the rotary hammer in addition.
Drill bit 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 use the rotary hammer in the
rotation and striking mode with the drill chuck
and chuck adapter attached. This would seriously
shorten the service life of every component of
the machine.
4. When driving wood screws (Fig. 13)
(1) Selecting a suitable driver bit
Employ plus-head screws, if possible, since the driver
bit easily slips off the heads of slotted-head screws.
