(2) How to drill
To use for drilling lumber
1
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 fi ne 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.
To use for drilling metal
2
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
effi ciency 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 (FD10VA)
(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.
