Lubrication
The bearings of the vibrating motors of the
HVE series are lubricated for life. Maintenance
of the bearings for this equipment is not
required.
The theoretical bearing life is:
Motor type
f = 50 Hz
f = 60 Hz
HVE/VFLE 2/2-6
7500 h
5500 h
HVE/VFLE 2/2-4
30000 h
20000 h
HVE/VFLE 2/2-2
65000 h
65000 h
HVE/VFLE 2/4
150000 h
150000 h
If there are any signs of wear or when the
theoretical bearing life is being reached, the
equipment should immediately be removed
from operation and the special bearings
replaced.
In this case, we recommend the equipment
to be sent to the manufacturer for repair (or
with any other damage). It is the only way to
ensure professional repair.
The electric vibrators must al-
ways be disconnected from the
electricity mains before any work
is carried out on it!
1. Switch off vibrator motor
2. Secure against being switched
back on again
3. Test for safe disconnection from
the power supply
4. Allow the vibratory motor to cool
Maintenance work to be carried out
regularly
• The surfaces of the motors must be kept
free from dirt in order to ensure adequate
cooling.
• Check the connection cable for chafe
marks and if applicable remove whatever is
causing them.
• Check fixing bolts for secure fit and if
necessary retighten.
• Check the seals.
The fixing bolts must be retight-
ened after approx. two operating
hours (following startup). Other
checks should be carried out
daily.
