*) In this case the unbalance must be reduced to 2,19 cmkg.
**) See table of eccentric adjustments on page 11.
Note:
In order to protect the vibrators against too high speeds, a flow control
valve should be used to limit the oil flow to the permitted quantity (see
required oil).
As a control measure check the frequency with a sirometer.
