.
Always check the direction of
rotat¡on
before operation
.
Use
the
reversing switch
lever
only after the
tool
comes
to a
complete
stop. Changing
the direction of rotation
before the tool
stops
may damage
the tool
.
When not operating the tool, keep the reversing

Drilling
operation
.
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
workoiece.
.
Dr¡ll¡ng in
metal
To prevent the bit
Ííom
slipping
when starting a
hole,
make an indentat¡on
with
a center ounch and hammer
at the point to be drilled. Place the point of
the
bit
in
the
indentation and start
drilling
Use
a
cutting
lubricant
when drilling metals. The exceptions are iron and brass
which should be drilled
drv.
CAUTION:
.
Pressing excessively on the
tool
will not
speed up the
drilling. ln fact,
th¡s excessive pressure will
only
serve
to damage
the tip of your bil, decrease the tool perfor-
mance and shorten the service
life
ol
the tool
.
There
is a
tremendous twisting force
exerted
on
the
tool/bit
at the
t¡me
of
hole breakthrough. Hold the tool
firmly and exert care
when
the
bit begins
to
break
through
the
workp¡ece. Use both hands
to
help control
the tool
.
A
stuck
bit can be
removed simply
by
setting
the
reversing switch to reverse rotation
in
order to back out.
However, the tool
may
back out abruplly il you
do
not
hold
it Íirmly.
.
Always secure small workpieces ¡n
a
vise
or
similar
hold-down device.
Screwdriving
operation
Place the ooint
of
the driver bit in
lhe
screw head
and
apply pressure to the tool. Start the tool. Release the trig-
ger
just as
the screw bottoms
out lf
the trigger is
not
released,
the screw
may
strip out the
hole or lhe
screw
and/or bit may be damaged.
NOTE:
.
Make sure that the dr¡ver bit is inserted straight in the
screw head, or the screw and/or bit may be damaged.
.
When dr¡ving wood screws, predrill pilot holes
to
make
driving easier
and to prevent splitting of the workpiece
See the chart.
