IV. OPERATION & TROUBLE SHOOTING GUIDE
1. Installing Drills
Insert drill into chuck jaws about 1"
(25.4mm). When using a small drill do
not insert it so far that the jaws touch
the flutes of the drill. Make sure that
the drill is centred in the chuck before
tightening the chuck with the key.

2. Positioning Workpiece
Always place a piece of wood on the
table. This will prevent "splintering" or
making heavy burrs on the underside of
the workpiece as the drill breaks
through. The wood should contact the
left side of the column.
3. Using Vise
For small workpiece
that cannot be clamped
to the table, use a drill
press vise. The vise
must be clamped or
bolted to the table.
