How To Use; Maintenance And Inspection - HIKOKI FDV 16VB2 Instrucciones De Manejo

English
CAUTION
○ Never change the direction of bit rotation during
operation.
Turn the power switch OFF before changing the
direction of bit rotation; otherwise, the motor will
burn.
○ Always use with clockwise rotation, when using
it as an impact drill.
9. IMPACT to ROTATION changeover (Fig. 5)
The impact drill can be switched from IMPACT
(impact plus rotation) to ROTATION (rotation only)
by simply sliding the change lever. When boring
concrete, stone, tile or similar board materials, slide
the change lever right. The drill head impacts against
the material while continuing to rotate.
When boring metal, wood or plastic, slide the
change lever fully to the left. The drill simply rotates
as an ordinary electric drill.
CAUTION
Do not use the impact drill in the IMPACT mode if the
material can be bored by rotation only. Such action
will not only reduce drill effi ciency, but may also
damage the drill tip.
When changing over, ensure the change lever is slid
as far as it will go.

HOW TO USE

1. Pressure
Drilling will NOT be accelerated by placing heavy
pressure on the drill. Such action will only result
in a damaged drill bit, decreased drilling effi ciency
and/or shortened service life of the drill.
2. Using a large diameter drill bit
The larger the drill bit diameter, the larger the
reactive force on your arm. Be careful not to lose
control of the drill because of this reactive force.
To maintain fi rm control, establish a good foothold,
hold the drill tightly with both hands, and ensure that
the drill is vertical to the material being drilled.
3. When drilling completely through the material
When the drill bit bores completely through the
material, careless handling often results in a broken,
drill bit or damage to the drill body itself due to the
sudden movement of the drill. Always be alert and
ready to release pushing force when drilling through
the material.
4. Switch operation
○ When the trigger is depressed, the tool rotates.
When the trigger is released, the tool stops.
○ The rotational speed of the drill can be controlled by
varying the amount that the trigger switch is pulled.
Speed is low when the trigger switch is pulled slightly
and increases as the trigger switch is pulled more.
○ The desired rotation speed can be pre-selected with
the speed control dial.
Turn the speed control dial clockwise for higher
speed and counterclockwise for lower speed. (Fig. 6)
○ 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.
CAUTION
Drill at a maximum rotation speed when drilling
wooden materials.
5. When driving wood screws
(1) Selecting a suitable driver bit
Employ plus-head screws, if possible, since the
driver bit easily slips off the heads of minus-head
screws.

(2) Driving in wood screws
○ Prior to driving in wood screws, make holes suitable
for them on the wooden board. Apply the bit to the
screw head grooves and gently drive the screws into
the holes.
○ After rotating the screwdriver at low speed for a
while until a wood screw is partly driven into the
wood, squeeze the trigger more strongly to obtain
optimum driving force.
CAUTION
○ Exercise care in preparing a hole suitable for the
wood screws 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.
○ Do not drive machine screws.

MAINTENANCE AND INSPECTION

1. Inspection the drill bit
Continued use of a worn and/or damaged drill bit
will result in reduced drilling effi ciency and may
seriously overload the drill motor. Inspect the drill
bit often and replace it with a new bit as necessary.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of
the screws be loose, retighten them immediately.
Failure to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
4. Replacing supply cord
If the replacement of the supply cord is necessary, it
has to be done by HiKOKI Authorized Service Center
to avoid a safety hazard.
5. Servicing
Consult an authorized Service Center in the event of
power tool failure.
6. Service parts list
CAUTION:
Repair, modifi cation and inspection of HiKOKI Power
Tools must be carried out by a HiKOKI Authorized
Service Center.
This Parts List will be helpful if presented with the
tool to the HiKOKI authorized Service Center when
requesting repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
MODIFICATION:
HiKOKI Power Tools are constantly being improved
and modifi ed to incorporate the latest technological
advancements.
Accordingly, some parts may be changed without
prior notice.
NOTE:
Due to HiKOKI's continuing program of research and
development, the specifi cations herein are subject to
change without prior notice.
