POSITIONING TABLE AND WORKPIECE
Lock the table to column in a position so that the tip
of the drill bit is just a little above the top of the work
piece.
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 bit
breaks through. To keep the backup material from
spinning out of control, it must contact the left side of
the column, as
illustr~ted.
WARNING: TO PREVENT THE WORKPIECE OR
THE
BACKU~P
MATERIAL FROM BEING TORN
FROM YOUR HAND WHILE DRILLING, POSI
TION THEM AGAINST THE LEFT SIDE OF· THE
COLUMN. 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.
For small pieces that cannot be clamped to the table,
use a Drill Press Vise (Optional accessory.)
WARNING: THE VISE MUST BE CLAMPED OR
BOLTED TO THE TABLE TO AVOID INJURY
FROM SPINNING WORK AND VISE OR TOOL
BREAKAGE.
INSTALLING DRILL BITS IN CHUCK
With the switch off and the key removed, insert drill bit
into chuck far enough to obtain maximum GRIPPING of
the CHUCK JAWS ... the jaws are approx. 1" long. When
using a small drill bit do not insert it so far that the jaws
touch the flutes (spiral grooves) of the drill bit.
Make sure that the drill bit is CENTRED in the chLJck
before tightening the chuck with the key.
Tighten the drill bit sufficiently, so that it does not SLIP
while drilling.
Turn the chuck key clockwise to tighten -
counter
clockwise to loosen the drill bit.
