•
At low temperatures: The machine is too cold and must be
heated up to room temperature in a warm room.
•
Cables which are too thin or too long are used for the electri-
cal connection:
Power cables with wire cross-sections which are too small
(mains voltage 220 V or 230 V smaller than 2.5 mm², mains
voltage 400 V smaller than 1.5 mm²) or with a total length of
more than 20 m lead to a loss of power and are not allowed
for safety reasons!
•
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 V-belts are too tight and must be loosened (
Sec-
tion 7.10, Replacement and tensioning of V-belts
