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.
Always place a piece of backup material
(wood, plywood, etc.) on the table under-
neath the workpiece. This will prevent
“splintering” or making a heavy burr on
the underside on the workpiece as the
drill breaks through. To keep the backup
material from spinning out of control, it
must contact the left side of the column,
as illustrated.
WARNING: To prevent the work-
piece or the backup material from
being torn from your hand while
drilling, position them against the
left side of the column. If the work-
piece or the backup material are not
long enough to reach the column,
clamp them to the table. Failure to
do this could result in personal
injury.
For small pieces that cannot be clamped
to the table, use a drill press vise (not
included).
WARNING: The vise must be
clamped or bolted to the table to
reduce the risk of injury from spin-
ning work and vise or tool break-
age.
