When
using
a
small
drill
do
not
insert
it
so
far
that
the jaws touch the flutes (spiral grooves) of the drill.
Make
sure
that
the
drill
is
CENTERED
in
the
chuck
before
tightening the chuck with the key.
Tighten
the
drill
sufficiently,
so
that

not
SLIP
while

POSITIONING TABLE AND WORKPIECE
Lock
the
table
to
the
column
in
a
position
so
that
the
tip
of
the
drill
is
just
a
little
above
the
top
of
the
workpiece.
It
is
not

to
reposition
the
TABLE
SUPPORT
COLLAR
each
time
you
reposition
the
table.
Always
keep
the collar locked about 34 in. from the floor.
Always
place
a
piece
of
BACK-UP
MATERIAL
(wood,
plywood
,
,
.)
on
the
table
underneath
the
workpiece.
This
will
prevent
"splintering"
or
making
a
heavy
burr
on
the
underside of the workpiece as the drill breaks through.
Position
workpiece
to
butt
against
the
column
whenever
possible
—
if
it
is
too
short,
clamp
solidly
to
the
Table
~
this
is
to
prevent
the
drill
bit
from
grabbing
the
work
from
your
hands,
which
could
result
in
personal
injury.
A
drill
press vise must be fastened to the table.
CAUTION: To prevent the workpiece or the back-up
material from being torn from your hand while drilling,
position them against the left side of the column. Failure to
do this could result in personal injury.
CAUTION: If the workpiece or the back-up material are
not long
enough
to reach the
column,
CLAMP them to the
table. Failure to do this could result in personal injury.
