Lubrication
See instructions in the manual of the motor manufacturer.
Maintenance and assembly instruction
The lubrication of the motor friction bearings has to be done according to the instructions of
the motor manufacturer. Quiet running of the fan must be checked regularly. Unsteady running
is caused by deposition in the impeller or by wear (unbalance) or by damage of the impeller
produced by foreign substances. Take suitable steps (cleaning, changing of defective parts,
lining-up) when the damage or cause for unsteady running is well-known. Unsteady running
leads to vibrations and faults in material.
