Installing drill bits
Inser1 drill bit intc chuck (A) far enough to obtain
1
maximum gripping of chuck jaws (B). (When using
a small drill bit do not insert it so far that the jaws
touch the flutes -spiral grocves -of the drill bit. )
2 Make sure that the drill bit is centered in the chuck
before tightening the chuck w th the chuck key
(C). optional.
Tighten the drill chuck sufficiently, so that the drill
3
bit does not slip while drilling.
Turn the chuck key clockwise to tighten, anticlock-
4
wise to loosen. Tighten the drill bit equally by using
all three holes in successicn. The drill bit can be
release by using one hole only.
Choosing speed and tensioning belt, Fig. 13
Note! Pull power plug!
You can set different spindle speeds on your pillar
1
drilling machine:
2 WITH THE SWITCH „OFF", open pulley cover.
3 Loosen the drive belt on the right side of the ma-
chine head by unfastening the wing screws (12)
on both sides. Pull the right side of the motor in
the direction of the spindle to loosen the v-belt.
Tighten the wing screws again.
4 Attach the v-belt to the corresponding belt pulleys.
5 Loosen the wing screws and push the right side
of the motor backwards to clamp the v-belt again.
Tighten belt tension lock knob. Belt should deflect
6
approximately 13 mm –1/2" -by thumb pressure at
mid-point of belt between pulleys.
Close pulley cover .

8 If belt slips while drilling readjust belt tension.
Tip: Safety switch
If you want to adjust speed you have to open the pul-
ley cover. The device switches off immediately to
avoid the risk of injuries.
Removing the chuck
Open jaws of chuck as wide as they go by turn-
ing chuck sleeve anticlockwise (when viewed from
above).
Carefully tap chuck with mallet in one hand while
holding chuck in other hand to prevent dropping it
when released from spindle nose.
Depth stop, Fig. 14
The depth stop enables the drilling of holes in the
workpiece until a defined depth. You have two op-
tions for that.
Drilling to a specific depth.
1 Mark the drilling depth (H) on one side of the work-
piece.
WITH THE SWITCH „OFF", bring the drill bit down
2
until the tip or lips are even th the mark.
Hold the feed handle at this position.
3
4 Spin the lower nut (B2) down to contact the depth
stop lug (13) on the head.

5 Spin the upper nut (B1) down and tighten against
the lower nut.
The chuck and the drill bit wiII now be stopped
6
after traveling downward the distance selected on
the depth scale.
Depth scale method, Fig. 6
Note: for this method, with the spindle in its upper po-
sition the tip of the drill bit must be just slightly above
the top of the workpiece.
Switch off the machine, lower the drill so far until
1
the indicator (g) points at the desired drilling depth
of the depth scale (e).
2 Turn the lower nut (B2) downwards until it reaches
the lower stop (13).
Lock the lower nut (B1) against the upper nut.
3
The chuck and the drill bit will now be stopped
4
after traveling downward the distance selected on
the depth scale.
Positioning table and workpiece, Fig. 15
Always place a piece of back up material (H) ('wood,
plywooood...) on the table undemeath the workpiece
(B). This wiII prevent splitering or making a heavy
burr on the underside of the workpieces as the drill
bit breaks through. To keep the back up 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 whiile drilling, position
them to 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.
Note: for small pieces that cannot be clamped to the
table, use a drill press vise (Optional accessory).
The vice must be clamp or bolt to the table to avoid
injury from spinning work and vise or tool breakage.
Drilling a hole.
Make a dent in the workpiece where you want the
hole, using a center punch or a sharp nail. Before
turning the switch on, bring the drill down to the
workpiece lining it up with the hole location.
Turn the switch on and pull down on the feed handles
with onIy enough effort to allow the drill to cut.
FEEDING TOO SLOWLY might cause the drill bit to
burn.
FEEDING TOO RAPIDLY might stop the motor,
cause the bett or drill to slip, tear the workpiece
loose, or break the drill bit.
When drilling metal, it may be necessary to lubricate
the tip of the drill with motor oil to prevent burning the
drill bit.
