14.1 Operational malfunctions
14.1.1 General information
The operator/operating personnel must perform
visual fill level control of the lubricant reservoir
at regular intervals. The control intervals de-
pend on the amount of lubricant required and
the pump's run time. The operator/operating
personnel must therefore determine the inter-
vals on their own based on the specific condi-
tions of usage.
If the reservoir has been emptied, the entire
system must be ventilated after refilling (see
Chapter 6, Assembly).
