5.4.3 Cleaning the electrical cabinet
Although the electrical cabinet is con-
structed to shut off external air, foreign parti-
cles such as dust and dirt may enter the
cabinet when the door is open.
Accumulation of foreign particles on the
printed circuit boards or other electronic
components could cause machine malfunc-
tion.
Clean the inside of the electrical cabinet
regularly.
Remove dust inside electrical cabinet with a
vacuum cleaner. Do not use compressed air
to clean the electrical cabinet.
Never touch circuit boards or parts around
the connector. Also avoid hitting these parts
with the vacuum.
We recommend that the electrical cabinet is cleaned every 1000 operating hours .
5.4.4 Refilling the oil in the central lubrication system
The central lubrication system lubricates important functional parts of the milling machine. The
maximum fill amount is 2 litres. If levels drop below the minimum fill amount, an audible alarm is
triggered.
