5. If the transport speed only increases when the screw is loosened and does not

decrease again even when the screw is fully loosened, the drive unit is too rigidly

tuned. In this case, remove a leaf spring and retune the frequency. You must re-

move as many leaf springs as necessary until the properties described in point 4)

are achieved. If you have to remove several leaf springs, they must be removed

as evenly as possible from the three spring assemblies on the bowl side.

6. If the transport speed decreases immediately while the screw is being loosened,

the drive unit is tuned too softly. In this case, fit a leaf spring and retune the fre-

quency. You must add as many leaf springs as necessary until the properties de-

scribed in point 4) are achieved. If you have to add several leaf springs, they must

be added as evenly as possible to the three spring assemblies on the bowl side.

The fitted leaf springs must be clean and dry.

Only one spring assembly must be dismantled at a time. To tighten the screw after tuning

the bowl feeder, apply the appropriate installation tool

in order to prevent the bowl feeder from twisting. The spring assemblies connected to the

counter weight must not be loosened.

After you have adjusted the natural frequency, the magnet gap must be checked.This

can easily become maladjusted whilst you are fitting or removing springs. If this is the

case the magnet gap must be reset as described in section 6.2 Adjusting the magnet

gap.

6 Maintenance instructions

A type BF bowl feeder essentially requires no servicing. The leaf springs, however, may

oxidize in certain conditions of use, thus affecting the vibration behavior in the long run.

In these cases the leaf springs must be removed and cleaned or be changed. In rare

cases the leaf springs must be completely replaced.

Only one spring assembly may be dismantled at a time when removing the leaf springs.

Before undoing the screws the centering brackets

to the drive unit

(see Figure 7)

thus prevent these parts sagging or moving.

The leaf springs must not be oiled or greased as this would make the

springs sticky and in turn adversely affect the vibration response.
