POSITiONiNG TABLE AND WORKPIECE
Lock the table tothe column in a positionso that thetip
ofthe drill isjusta little above the topof the workplece.
Always place a piece of BACK-UP MATERIAL (wood,
plywood...) on the table underneath the workpiece.
This willprevent "splintering" or making a heavy burr on
the underside on the workpiece as the drill bit breaks
through. To keep the backup materialfrom spinningout
of control,it must contactthe left side of the column,as
illustrated.
WARNING: To prevent the workpiece or the
backup material from being torn from your
hand while drilling, position them against the
left side of the column, if the workpiece and 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.
