table, must not be exceeded. The lower the centrifugal force is set, the less is the wear of
moulds and vibrators.

Adjustment of the direction of rotation

Remove a cover to be able to check the direction of rotation.

Switch on the vibrator shortly and detect direction of rotation.

If it is necessary to change the rotation, turn the main switch off and secure it against
incidentally activation.

Swap the connection of 2 leads of the power cable, e.g. at the connector or at the
distribution panel. Do not swap leads in the terminal box of the vibrator!

Mount the cover again.

Adjustment of the unbalance

The unbalances of the vibrators are normally set to the maximum generation of centrifugal
force for which the vibrator was designed for.

Remove both covers.

Loosen the clamping screw of the adjusting unbalance on one side and adjust
according to the following diagram on the next page

Adjust the unbalance on the other side of the rotor shaft the same way

Tighten clamping screw again.

Perform the same adjustment of the unbalance on the other side of the rotor shaft and
tighten the clamping screw.

Remount the covers.
