Use the variable speed select knob (V,
Fig 2) to set the spindle speed.
The digital readout (U) displays the
actual speed.
7.3 Auto feed overload protection
The auto feed mechanism is equipped
with an overload protection clutch.
First the downfeed will stop, then the
feed handles will disengage and the
spindle will return to the top by spring
force.
Stop the machine immediately under
this condition.
Check the job-setup:
Make sure that the drill bit is sharp and
the machine adjustments are correct.
Wenn die Maschine beim Betrieb mit
automatischem Vorschub überlastet
wird, kommt die Ueberlastkupplung
zum Einsatz.
Der Vorschub setzt bei laufender
Spindel aus, es fallen die
Vorschubhebel und Pinole
automatisch in die Ausgangsstellung
zurück.
Ist dies der Fall, die Maschine sofort
abstellen.
Ueberprüfen Sie das Werkzeug
(Schärfe) und die
Maschineneinstellungen.
Adjustment:
The overload protection clutch has
precisely been adjusted ex works and
may only be readjusted by a qualified
person.
If the job setup is correct and the
overload clutch reacts, it may be
adjusted as follows:
Remove the „overload protection“
cover plate.
Tighten the nut clockwise by ¼ turn
(Fig 14).
Fig 14
Test the auto feed drilling
performance. If needed, repeat the
adjustment.
Reinstall the cover plate.
ATTENTION:
Overtightening the clutch may damage
the feed mechanism.
8. Maintenance and inspection
General notes:
Maintenance, cleaning and repair
work may only be carried out after
the machine is disconnected from
the power source. Pull the mains
plug!
Clean the machine regularly.
Defective safety devices must be
replaced immediately.
Repair and maintenance work on the
electrical system may only be carried
out by a qualified electrician.
Changing oil:
Drain oil after first month of operation.
by removing drain plug and refill with
oil.
Gear box oil (SAE 90)
Then change the oil annually
(respectively every 700 operating
hours).
Weekly lubrication:
Once a week lubricate gently with
grease.
-the teeth of the quill
-the column-rack
Coolant facility:
Pour 8 litres of coolant mix into the
coolant tank (Z, Fig 15).
Fig 15
Follow coolant manufacturer’s
recommendations for use, care and
disposal.

9.1 Frequency inverter
Installation and repair of the frequency
inverter may only be carried out by a
qualified electrician.
The following points have to be
observed:
1) Disconnected from the power
source. Pull the mains plug!
2) Electronic components are very
sensitive, do not touch with bare
hands or non-isolated metal tools.
3) The DC-capacitor remains under
voltage, even when the machine is
disconnected from mains.
Assuer that all LED´s are off before
you start service work.
