where they do not distort or deform the base plate.
Excessive tension can lead to fracture.
Quill return spring (Fig. 9):
It may be necessary to adjust your quill return
spring if the tension is such that the quill returns
either too quickly or too slowly. To do so, lower
the table for additional clearance. Work from left
side of drill press. Move the stop nuts (B 1/2) down
to their lowest position and lock in place with
wrench to prevent quill dropping while tensioning
spring. Place screwdriver in lower front notch (C)
of spring cap (D), and hold it in place. Remove the
screw (E) and the nut (E) by using an Allen wrench.
Carefully turn screwdriver anticlockwise and en
-
gage next notch in boss (G). Do not remove screw
-
driver. Install the nut (E) and the screw (E) again.
If there is not enough tension on spring, repeat
steps moving one notch each time and check
-
ing tension after repetition. Proper tension is
achieved when quill returns gently to full up posi
-
tion when released from 20mm depth. Check quill
while feeding to have smooth and unrestricted
movement. If movement is too tight, loosen Allen
screw (E) and knurled nut (F). Check if the spindle
can move freely again and retighten.
The angular play of the spindle (Fig. 10):
With the spindle in a low position, take it in your
hand and try to make it revolving around its axis. If
there is too much play, proceed as follows:
1. Loosen lock nut (L).
2.
Turn the screw (I) 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.
NOTE:
The installed electric motor is completely wired
ready for operation. The customer‘s connection to
the power supply system, and any extension cables
that may be used, must conform with local regula
-
tions. Check electrical connection cables regularly
for damage. Make sure the cable is disconnected
from the mains when checking. Electrical connection
cables must comply with the regulations applicable
in your country.
Single-phase motor:
f
The mains voltage must coincide with the voltage
specified on the motor’s rating plate.
f
Dimension cables up to a length of 25m must have
a cross-section of 1.5mm
2
and beyond 25m at least
2.5mm
2
.
f
The connection to the mains must be protected
with an appropriate slow acting fuse.
NOTE:
The motor is automatically switched off in the event
of an overload. The motor can be switched on again
after a cooling down period that can vary.
WARNING:
Connect the machine only to a socket with the prop
-
erly installed ground contact.
OPERATING THE UNIT
WARNING:
For your own safety, keep the machine switch in off
position while performing any of the below proce
-
dures. Machine should be turned on, only if a specif-
ic step of the procedure states so and only for that
particular step.
Pivoting the table (Fig. 11):
To bring the table (3) to the inclined position, re-
lease the table locking (h) and adjust the desired
table angle. Re-tighten the table locking
Adjusting table height (Fig. 12):
Loosen the table support lock handle (b). Adjust
the table (3) to the desired height. Re-tighten the
table lock handle (b).
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 work piece.
Installing drill bits:
WARNING:
Only cylindrical tools with the stipulated maximum
shaft diameter may be clamped in the scroll chuck
(Fig. 1.5). Only use a tool that is sharp and free of de-
fects. Do not use tools whose shaft is damaged or
which are deformed or flawed in any other way. Use
only accessories and attachments that are specified
in the operating instructions or have been approved
by the manufacturer. If the pillar drill should become
jammed, switch off the machine and return the drill
to its starting position.
Insert the drill bit into chuck far enough to obtain
maximum gripping of chuck jaws. When using a
small drill bit do not insert it so far that the jaws
touch the spiral grooves of the drill bit. Make sure
that the drill bit is centered in the chuck before
tightening the chuck with the chuck key. Tight-
en the drill chuck sufficiently, so that the drill bit
does not slip while drilling.
Turn the chuck key clockwise to tighten, anticlock-
wise to loosen. Tighten the drill bit equally by us-
ing all three holes in succession. The drill bit can
be release by using one hole only.
Choosing speed and tensioning belt (Fig. 13):
You can set different spindle speeds on your pillar
drilling machine:
1.
Open pulley cover.
2.
Loosen the drive belt on the right side of the
machine head by unfastening the wing screws
(12) on both sides. Pull the right side of the mo
-
tor in the direction of the spindle to loosen the
v-belt. Tighten the wing screws again.
3.
Attach the v-belt to the corresponding belt
pulleys (Fig. 16). Available speeds are achieved
with the following v-belt combinations:
600 rpm
A
1
900 rpm
B
2
1.450 rpm
C
3
1.950 rpm
D
