4. For use as a drill
(1) Mounting drill bit
Tighten drill bit with the chuck wrench. There are
three holes in which the chuck wrench should be
inserted. Tighten them equally in turn at three holes,
without tightening them only at one hole. The drill
bit can be removed in the opposite method as
mentioned above. (Fig 3)
(2) How to drill
1 To use for drilling lumber
Apply the point of the drill bit to the desired drilling
position, hold the drill perpendicular to the workpiece
surface and turn on the switch.
When drilling a through hole in lumber, remove the
drill from the material as soon as the tip of the drill
bit protrudes from the opposite surface. Then, turn
the workpiece over and complete the drilling from
the opposite side to obtain a clean hole. (Fig. 4)
If extra lumber is applied under the lumber you
want to drill and it is drilled together, a fine hole
will also be made. (Fig. 5)
A wood-working drill need not be pressed strongly
since it penetrates using the screw at the point.
Even if excessive force is used, a hole will not be
made quickly.
2 To use for drilling metal
In case you drill metal with an iron-working drill,
apply in advance a center punch in the drilling
position. You can drill metal stably since the point
of the drill does not slip.
If you apply sewing machine oil or soapy water to
the drill with a brush or an old tooth brush, the
drill will last long.
Even if more-than-necessary force is used, a hole
will not be made quickly.
On the contrary, the edge of the drill will be
damaged. This will decrease operational efficiency
and shorten the life of this too.
CAUTION:
Do not expose the motor to water as it may cause
motor malfunction and electric shock.
5. To use the driving wood screws (FD10VB)
(1) Driver bit
For driving a minus wood screw, the driver bit
detaches easily. So use wood screws with a plus
groove as often as possible.
Select a driver bit matching the plus groove and
the minus groove of the wood screw.
(2) Pilot hole
If a pilot hole is made with a drill a little thinner
than the diameter of the wood screw, the lumber
will not be split and the wood screw will be driven
with ease.
(3) Driving operation
Put the wood screw lightly in the pilot hole, apply
the bit to the groove, turn on the switch and drive
the screw.
6. Caution to be taken immediately after operation
When placing the drill in dusty places before the
rotating parts has stopped completely, make sure
the machine does not suck in dust and swarf.
MAINTENANCE AND INSPECTION
CAUTION
Be sure to switch power OFF and disconnect the plug
from the receptacle during maintenance and inspection.
1. Inspecting the drill bit and driver bit
Since use of an abraded drill bit will cause motor
malfunctioning and degraded efficiency, replace the
drill bit with a new one or resharpening without
delay when abrasion is noted. If you use a driver
bit of which point is worn or broken, it will be
dangerous since it slips. So replace it with a new
one.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loosened, retighten them immediately,
Failure to do so could result in serious hazard.
3. Replacing supply cord
If the replacement of the supply cord is necessary,
this has to be done by Hitachi Authorized Service
Center in order to avoid a safety hazard.
If the supply cord of this power tool is damaged,
it must be replaced by a specially prepared cord
available through the service organization.
4. Servicing
Consult an authorized Service Center in the event
of power tool failure.
