10 Check quill while feeding to have smooth and unre-
stricted movement. If movement is too tight, loosen jam
nut and slightly loosen standard nut until unrestricted.
Retighten jam nut.
the angular play of the spindle, Fig. 10.3
With the spindle in a low position, take it in your hand and
try to make it revolving about its axis. If there is too much
play, proceed as follows:
1 Loosen lock nut (A).
2 Turn the screw (B) clockwise to eliminate the play but
without obstructing the upward and downward motion
of the spindle (a little bit of play is normal).
3 Tighten the lock nut.
wArning: if you are not familiar with this kind of ma-
chine, take advice
in any case you should have read and understood the safety
and operational instruction before attempting to operate this
product.
pivoting the table, Fig. 11.1, 11.2
Tip: The inclination display (a) only serves as orientation
for a rough angular adjustment. For precision work suit-
able goniometers must be used.
1 To bring the table (3) to the inclined position, release
the table locking (b) and adjust the desired table angle.
Re-tighten the table locking.
Adjusting table height, Fig. 11.1
1 Loosen the table support lock handle (A).
2 Adjust the table (3) to the desired height.
3 Re-tighten the table locking (A).
Note: it is better to lock the table to the column in a posi-
tion so that the tip of the drill bit is just slightly above the
top of the workpiece
installing drill bits.
1 Inser1 drill bit intc chuck (A) far enough to obtain
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.
3 Tighten the drill chuck sufficiently, so that the drill bit
does not slip while drilling.
4 Turn the chuck key clockwise to tighten, anticlockwise
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.

1 You can set different spindle speeds on your pillar
drilling machine:
2 WITH THE SWITCH „OFF", open pulley cover.
3 Loosen the drive belt on the right side of the machine
head by unfastening the wing screws (d) on both sides.
Pull the right side of the motor in the direction of the
spindle to loosen the v-belt (for type stb 16s: loosen
the v-belt by using the lever (e)). 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

from an experimented
motor backwards to clamp the v-belt again.
6 Tighten belt tension lock knob. Belt should deflect
approximately 13 mm –1/2" -by thumb pressure at
mid-point of belt between pulleys.
7 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 pulley
cover. The device switches off immediately to avoid the
risk of injuries.
removing the chuck.
1 Open jaws of chuck as wide as they go by turning chuck
sleeve (A) anticlockwise (when viewed from above).
2 Carefully tap chuck with mallet (B) in one hand while
holding chuck in other hand to prevent dropping it
when released from spindle nose.
person. depth stop, Fig 10.2 (only for stb t16 and stb s16)
The depth stop enables the drilling of holes in the work-
piece until a defined depth. Adjust the ring (6) usiing the
scale to the desired depth and tighten the ring with the
wing nut (7).
depth stop, Fig. 13 (only for stb t13)
The depth stop enables the drilling of holes in the work-
piece until a defined depth. You have two options for that.
drilling to a specific depth.
1 Mark the drilling depth (H) on one side of the work-
piece.
2 WITH THE SWITCH „OFF", bring the drill bit down
until the tip or lips are even th the mark.
3 Hold the feed handle at this position.
4 Spin the lower nut {B) down to contact the depth stop
lug {C) on the head.
5 Spin the upper nut {D) down and tighten against the
lower nut.
6 The chuck and the drill bit wiII now be stopped after
traveling downward the distance selected on the depth
scale.
depth scale method
Note: for this method, with the spindle in its upper posi-
tion the tip of the drill bit must be just slightly above the
top of the workpiece
1 Switch off the machine, lower the drill so far until the
indicator (E) points at the desired drilling depth of the
depth scale (F).
2 Turn the lower nut (B) downwards until it reaches the
lower stop (C).
3 Lock the lower nut (D) against the upper nut.
4 The chuck and the drill bit will now be stopped after
traveling downward the distance selected on the depth
scale.
positioning table and workpiece, Fig. 14
Always place a piece of back up material (A) ('wood, ply-
wood...) on the table undemeath the workpiece (B). This
wiII prevent splitering or making a heavy burr on the un-
derside 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 mate-
rial from being torn from your hand whiile drilling, posi-
tion them to the left side of the column. If the work piece
or the backup material are not long enough to reach the
