This section shows you how to remedy possible malfunctions. If
none of the measures listed here are successful, please contact
our service department, your retailer or your importer.
THE MACHINE DOES NOT RUN
The machine does not start
•
The machine is not connected to the electrical network. Check
the following items:
- Is the motor cable connected to the extension cable?
- Is the extension cable inserted into the power socket?
•
The power socket is not properly connected. This error must
be corrected by a professional.
•
The electrical safety device of the electrical network inter-
rupted the electrical circuit, e.g. because
- too many electricity consumers are connected to the same
electrical circuit,
- improper electrical installation.
The causes for the error must be repaired by an expert.
•
The electrical network is not providing sufficient voltage
(undervoltage). Use a transformer if necessary (e.g. LÄGLER
®
part number 708.00.00.100 for 230 volts).
•
The temperature switch in the motor has switched off the
machine because
- one or more power cables have a total length of more than
20 m
- the power cables has wire cross-sections which are too
small:
at mains voltage 220 V or 230 V are the wire cross-sections
smaller than 2.5 mm²
at mains voltage 400 V are the wire cross-sections smaller
than 1.5 mm²
- or too much pressure was applied to the sanding drum.
The motor must cool off and the causes for the problems
named above must be remedied.
•
An electrical component of the machine (e.g. capacitors,
contactor, cable, switch) is defective and must be inspected
by a qualified electrician and replaced if necessary.
