A
Check if the motor's cooling fan starts:
1. Turn the potentiometer slowly
and listen carefully:
a low buzzing noise should start.
•
2. Visually check that the fan runs by
detaching the control panel.
3. Replace a faulty fan (chap. 8).
5. Machine starts flashing rapidly after a longer period of drilling (5—60min)

1. Press control panel On/Off button; switch diode on and off.
2. Listen for a click noise from a relay inside the machine.
•
If no click noise, the emergency stop cable may be damaged.
3. Remove the control panel (chap. 6).
4. Remove cable from position K5 (chap. 8)
5. Check that this has contact when emergency stop is up and that the
contact is cut off when emergency stop is down.
8. Y-cable is faulty

Service guide & troubleshooting
Troubleshooting and suggested actions
Check attachment to drill pillar:
1. Remove power cable and use the drill pillar crank lever – check for unusual resistance.
2. Drilling with smaller drill crowns may discharge the machine over-load function.
•
Turn the potentiometer to mid-position and press the membrane button until the diode emits a continuous light.
3. When discharged due to over-load, the machine automatically reduces the maximum level, 1A below set potential value.
4. Reset machine by removing the power cable from power mains for a few seconds.
5. If the problem persists; send machine to service workshop.
B
1. Test feeding function by
mounting it on a DS450
stand;
2. Attach a scale between feeder
house and floor or directly on
the pillar.
•
The machine should be cap
able to pull a minimum of
290kg.
Important: increase the poten
tiometer carefully up to max. 20%
of the available range.
Check attachment to drill pillar.
1. Remove AD 10 and use the crank lever of the drill pillar – check for heavy resistance.
2. Check if the drill crown is worn out, is uneven or if the segments are glazed.
3. The ambient temperature should be below 40°C (104°F) and the machine should not be used in direct sunlight.
4. If the problem persists; send machine to service workshop.
Same as above "4. Machine starts flashing rapidly after a short period of drilling (1—5min)"
Check that the M4-screw is tightly secured in the gear house lid (chap. 5, page 11, ill. 2).
1. Check that AD 10 diode emits a continuous light.
2. Check; that the PRCD of the drill motor is activated (press reset), check that the drill motor is switched on.
3. Connect drill motor directly to power outlet (not via the automatic drill feeder AD10).
4. If drill motor only works when connected directly to power outlet, send machine to service workshop.
A
Send machine to service workshop.
Disassemble Y-cable and replace it (chap. 6—7).
C
If the machine is capable to pull less
than 200 kg:
1. Listen for noise from the gear
box.
•
In case of noise, the gearbox
should be dismantled it's parts
thoroughly checked (chap. 5).
2. Replace any parts that appear
worn or damaged.
1. Disassemble (chap. 6).
2. Connect the control panel.
3. Connect unit to earthed outlet with residual-current device (RCD) and
switch unit on.
4. Measure the voltage with multimeter over earth and position M (chap. 8).
5. If voltage is zero, the relay of the unit is damaged and the entire circuit
board should be replaced.
6. If there is voltage, the Y-cable is faulty and should be replaced.
D
In case of no noise or no apparent
fault with the gearbox:
•
Replace the motor—pinion-unit
(chap. 6—9).
