• Pressure marks caused when connecting leads are run through windows or the cracks of doors.
• Folds caused by the improper attachment of running of the connecting leads.
• Cuts resulting from the crossing of the connecting lead.
• Insulation damages caused by the ripping out of the connecting lead from the wall socket.
• Cracks due to the ageing of the insulation.
Faulty electrical connecting leads such as these may not be used and are highly dangerous due to the
insulation damage.
Check electrical connecting leads regularly for damage. Ensure that the connecting lead is not
attached to the mains supply when you are checking it. Electrical connecting leads must correspond
to the relevant VDE and DIN regulations. Only use connecting leads with the code H05VV-F.
The type designation must be printed on the connecting lead by regulation.
AC motor
• The supply voltage must be 230 volt ~ / 50 Hz.
• Extension leads up to 25 m in length must have a cross-section of 1.5 mm², > 25 m length / 2,5
mm². Connections and repairs of electrical equipment may only be performed by a qualified
electrician.
Please give the following information if you have any enquiries:
• Kind of current
• Machine type label data
• Data on the main label
13. Troubleshooting
The determination of the causes of these interference and their elimination always require
heightened attention and caution. Pull the mains plug!
In the following are some of the most common interferences and their causes listed. If you cannot
correct faults and errors with the machine, please contact your dealer.
Disturbance
Machine cannot be switched on No mains voltage available.
Machine switches off during
the no-load operation
independently
Machine remains during
working on standstill
Number of revolutions drops
during the treatment
Careless milling picture
Splinter ejection clogs (without
EN
Probable cause
Carbon brush conductors worn
out.
Power failure
Response of the overload
protection because of blunt
measurers or of too large feed
motion and/or thickness of chip
Too large splinter acceptance
Too large feed motion
Milling cutter blunt
Milling cutter blunt
Uneven feed motion
Too large splinter acceptance
Help
Control Voltage supply
Bring Machine into the service
centre
Control Net-lateral Pre-fuse
The machine does not restart
by the inserted under-voltage
protection automatically and
must again be switched on
after tension return.
Before continuing with work
exchange measurers and/or
wait for cooling of the engine.
Reduce Splinter acceptance
Reduce Feed speed
Replace milling cutter
Replace milling cutter
Work with constant pressure
and reduced feed motion
Reduce Splinter acceptance
