4.1 ADDITIONAL WEIGHTS ASSEMBLING
WARNING: This operation must be carried out exclusively by
specialised staff and with the drive motor with the power supply
disconnected.
WARNING: When working on the exciter the eccentric weights
may turn and so there is knocking danger.
WARNING: Mounting of additional weights can determine the
rotation of eccentric weights, pay attention for knocking.
To assemble the additional weights proceed in the following indicated
sequence:
- Verify on the eccentric weights that both the holes for the additional
weights and the radial holes for the fixing elastic pins are free.
- Introduce the additional weight in the hole in such a way that the
radial hole in the additional weight corresponds to the radial hole
of the eccentric weight.
- Push the additional weight up to a complete introducing in the
eccentric weight, than the radial holes of additional weight and
eccentric weight have to correspond.
- Push the fixing elastic pin in the hole of the eccentric weight, till the
pin it's completely into the diameter of the eccentric weight.

4.2 ADDITIONAL WEIGHTS REMOVAL
WARNING: This operation must be carried out exclusively by
specialised staff and with the drive motor with the power supply
disconnected.
WARNING: When working on the exciter the eccentric weights
may turn and so there is knocking danger.
WARNING: Removal of additional weights can determine the
rotation of eccentric weights, pay attention for knocking.
Proceed in the following indicated sequence:
- Start removing additional weights from the driven shaft.
- Push the fixing elastic pin radial inside the additional weight to be
removed.
- Rotate the weights in such a way there is no overlapping of the
additional weight with the eccentric weight of the short shaft.
- Remove the additional weight from the eccentric weight by lightly
tapping it.
- Remove the fixing elastic pin from the disassembled additional
weight.

4.3 WEIGHT COVER MOUNTING
WARNING: Before start driving the exciter it's absolutely ne-
cessary to assemble the weight covers to protect the eccentric
weights. Drive the exciter without weight covers it's a risk for
the vibrating machine and for the people safety.
The weight covers are composed of 3 parts in the coupling side and
of 4 parts in the other side:
- 1 - main protection weight box
- 3 - side end cover
The standard supply of the exciter is with the coupling side at the
right respect to the identification plate. The user can invert position
of the coupling side, easily moving in the opposite side the shaft
protection n°4.
In case of coupling of two or more exciters in series the user have,
for each added exciter, to remove the protection n°4 and install the
second opening kit, available on request.
WARNING: To correctly protect the eccentric weights it's neces-
sary to assemble the weight covers with all their parts. Otherwise
it would be a risk for people safety.
WARNING: In the weight cover assembling be aware that all
screws are correctly tightened with a suitable dynamometric
wrench following the indicated torques:
