Always use the side grip to ensure operating safety.
Install the side grip so that the teeth on the grip fit in
between the protrusions on the tool barrel. Then tighten
the grip by turning clockwise at the desired position.
NOTE:
The depth gauge cannot be used at the posi
-
tion where the depth gauge strikes against the tool
body.
Installing or removing drill bit

Chuck key
To install the drill bit, place it in the drill chuck as far as
it will go. Tighten the chuck by hand. Place the chuck
key in each of the three holes and tighten clockwise. Be
sure to tighten all three chuck holes evenly.
To remove the drill bit, turn the drill chuck key counter
-
clockwise in just one hole, then loosen the chuck by
hand.
After using the chuck key, be sure to return it to the
original position.

Drilling operation
Drilling in wood
When drilling in wood, the best results are obtained
with wood drills equipped with a guide screw. The guide
screw makes drilling easier by pulling the drill bit into
the workpiece.
Drilling in metal
To prevent the drill bit from slipping when starting a
hole, make an indentation with a center-punch and
hammer at the point to be drilled. Place the point of the
drill bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The excep
-
tions are iron and brass which should be drilled dry.
CAUTION:
Pressing excessively on the tool
will not speed up the drilling.
In fact, this excessive
pressure will only serve to damage the tip of your drill
bit, decrease the tool performance and shorten the
service life of the tool.
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece.
There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it firmly.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
CAUTION:
Avoid drilling in material that you
suspect contains hidden nails or other things that
may cause the drill bit to bind or break.
