the enclosure.
Every time a maintenance, repair or overhaul operation is carried
out on a vibrator, is necessary to check the seals conditions and
the correct placement in the seats.
When the product is used in zones 21-22, the O-rings have to be
changed every two years of use.
Only authorised technicians can intervene on the parts that make
up the vibrator. Before carrying out maintenance on the vibrator
wait until the temperature of the vibrator case is not above 40°C and
ensure that the electrical power supply has been disconnected. If
parts must be replaced, only ITALVIBRAS original spare parts must
be used.
All maintenance, repair and overhaul operations carried out by a
third part and not by ITALVIBRAS void warranty.

5.0 ADMITTED AND NOT ADMITTED ACTIONS BY USER

The Series E electric vibrator are suitable to be used in potentially
explosive atmospheres and the safety operation in such environ-
ments is assured by the protection mode of these vibrators and so
by the component used and by assembling process. Therefore the
admitted works by user for repairs, overhauls and maintenance are
strictly limited.
The only admitted maintenance actions for user are:
- external vibrator cleaning, to periodically eliminate excess of dust
and dirty;
- periodical lubrication, following what mentioned in next par.5.1.
- replacement of wiring box cover, weight covers and relative seals,
only with original ITALVIBRAS spare parts.
Maintenance and repairs involving removal of vibrator parts are
NOT admitted, except for:
- wiring box cover to connect the supply cable to the electric
board;
- weight covers to adjust and replace the eccentric weights and to
check the rotational sense of the shaft.
In case it is necessary to remove other parts not listed above, it's
strictly necessary to contact Italvibras - Fiorano Modenese (Italia).
Within these forbidden actions are also included the bearing repla-
cement, the removal of stator and other inner parts.
It's extremely important to check the bearing's conditions to avoid
that an excessive wear cause the unbalancing of the shaft and the
danger of stripment of the rotor with the stator. Then if an increa-
sing bearing noise is noted, the bearing replacement is strictly re-
commended.
In case of troubles always contact Italvibras.
In case the bearing checking it's not possible, we recommens to
plan bearings replacement at the calculated theoretical bearings
life time (page 97 and following).
ATTENTION: Every time the afore-mentioned maintenance ope-
rations are carried out it is recommended that all disassembled
screws and spring washers are replaced and that the screws are
tightened using a dynamometric wrench.
5.1 LUBRICATION
All bearings are correctly lubricated on mounting the vibrator.
Therefore when the vibrator is supplied the user DON'T have to lu-
bricate it.
All ITALVIBRAS vibrators are realised to use the "FOR LIFE", lubri-
cation system and therefore do not compulsorily require periodical
lubrication.
For a correct use of the bearings Italvibras recommend in any case
a periodical lubrication every 3000-5000 hours.
Only for heavy work, as for example 24 hour service with high environ-
mental temperatures, starting from frame sizes AF33 and 35 periodical
re-lubrication of the bearings is mandatory, using the two external grea-
sers with the following type of grease:
- speed of 3000 rpm or higher: KLUEBER ISOFLEX NBU 5;
- speed of 800 rpm or lower: KLUEBER STABURAGS NBU 8 EP;
- MVSI special series 600-720 rpm: KLUEBER ISOFLEX NBU 5.
Approximately, on average, the frequency of re-lubrication can be inclu-
ded between 000 and 5000 hours and depends on the operative condi-
tions and the type of vibrator, therefore it can be lower or higher than the
indicated values. The quantity of grease to be introduced on periodical
lubrication is indicated in the table on page 97. It is advised to contact
ITALVIBRAS for particular uses which is at complete disposal to advise
the client on the best lubrication possible for the specific use.
Never mix greases even if they have similar features. Excessive
quantity of grease causes increased heating of the bearings and
consequent anomalous current absorption.
Respect the ecological laws in force in the country in which the
equipment is used, relative to use and disposal of products used
for cleaning and maintenance of the vibrator. Always comply with
recommendations of the manufacturer.
If the machine must be demolished, comply with the anti-pollution
regulations envisioned in the country of use.
Remember that the Manufacturer is always available for any type of
assistance and spare parts.

5.2 SPARE PARTS

On requesting spare parts always state:
- Type of vibrator (TYPE detectable from the identification plate).
- Serial number (SERIAL NO. detectable from the identification plate).
- Power supply voltage and frequency (VOLT and HZ detectable from
the identification plate).
- Spare part number (detectable from the spare part table starting from
page 03) and desired quantity.
- Exact destination address of the goods and means of delivery.
ITALVIBRAS declines any liability for incorrect forwarding due to
incomplete or confused requests.
It's ITALVIBRAS option to DON'T supply some spare parts when
these component are part of a forbidden overhaul.
ITALVIBRAS declines any liability for maintenance operations car-
ried out by a third part company, even if using original spare parts.
