Drilling in wood
When drilling in wood, best results are obtained with wood drills equipped with a guide
screw. The guide screw makes drilling easier by pulling the bit into the workpiece.
0
Drilling in metal
To prevent the b i t from slipping when starting
a hole, make an indentation with a center-
punch and hammer a t the point t o be drilled place the point of the bit in the indenta-
tion and start drilling.
Use a cutting lubricant when drilling metals. The exceptions 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 t i p of your bit, decrease the tool performance
and shorten the service life of the tool.
.There is a tremendous force exerted on the tool/bit
a t
the time of hole breakthrough.
Hold the tool firmly and exert care when the bit begins t o break through the workpiece.
.A stuck b i t can be removed simply
by
setting the reversing switch t o reverse rotation in
order t o back out. However, the tool may back out abruptly if you do not hold
it
firmly.
.Always secure small workpieces in a vise or similar hold-down device.
Overload
protector
The overload protector automatically cuts out to break the circuit whenever heavy work
i s
prolonged. Wait 20-30 seconds before resuming operation.
CAUTION :
Always withdraw the tool from the workpiece before resuming operation. If the tool
cannot be withdrawn, hold the tool firmly when turning on the tool, to overcome a
strong reaction.
Hook
A hook is provided as
a
standard equip-
ment. This hook is convenient for tem-
porarily
hanging the
tool.
To install the
hook, first insert one end of the hook into
one slot in the tool body and then insert
the other end into the other slot. Secure
the hook with the screw. The hook can be
installed on either left or right side of the
tool.
