Maintenance And Inspection - Hitachi Koki FD10VB Handling Instructions Manual

(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 a metal-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 tool.
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 slotted head wood screw, the driver
bit detaches easily. So use cross-recessed head
wood screws as often as possible.
Select a driver bit matching the cross-recessed and
the slotted groove of the wood screw.
(2) Pilot hole
If a pilot hole is made with a drill a little smaller 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 screw head 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
during maintenance and inspection.
1. Inspecting the drill bits 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 loose, retighten them immediately. Failure
to do so could result in serious hazard.
3. Servicing
Consult a Hitachi Authorized Service Center in the
event of power tool failure.
