Assure that both unbalance sides are adjusteed in the same direction,
that they show the same marking and that they are positioned firmly
against each other. The two basis unbalances (inner weights) should
in no case be adjusted. Should it be however necessary please assure
that both basis unbalances are mounted in exactly the same position
and unidirectional on the shaft. Furthermore ensure that the basis
unbalance will be pressed firmly against the distance ring.

-Maintenance Of Vibrators-
General care
The outer housing of the vibrators should be cleaned regularly from strong contaminants.
Housings with cooling fins are to be kept dirt-free in order to secure good heat dissipation.
The cleaning with high pressure steam or high pressure water is not permitted because water
can penetrate into the interior and destroy the electrical winding.
The fixing bolts of the vibrator foot and those of the unbalance covers should be examined for
the right tightening torque and should be re-tightened if necessary. Defective fixing bolts
should be replaced by new screws.
Maintenance
The minimum maintenance plan has to be kept obligatory.
After the first 10 operating hours all fixing bolts and nuts should be examined of their
tightness and if necessary should be tightened or replaced by new bolt connections.
Secured bolt connections (we recommend with Loctite) should not be re-tightened but should
be exchanged and secured again if these have loosened.
The power consumption and the operating temperature of the vibrators should be supervised.
The power consumption shall not exceed the value of the nameplate and the operating
temperature measured on the surface of the motor housing shall not 70°C.
