Safety regulations

2.0 SAFETY

Users are advised to become fully familiar with the instructions in this booklet, particularly
the safety regulations, paying great attention to those operations that are particularly
dangerous.
The Manufacturer declines all and every responsibility for failure to comply with
the safety and accident-preventing provisions described herein. The Manufacturer
also declines all responsibility for damage caused by improper use of the motor-
driven vibrator or by modifications accomplished without authorization.
Pay attention to the danger signs in this booklet. They precede an indication
of a potential danger.

2.1 GENERAL SAFETY SPECIFICATIONS

When electrically operated equipment is used, it is necessary to take all
the necessary safety precautions in order to reduce the risk of fire outbreak,
electric shocks and personal injuries. Before the motor-driven vibrator is
used, it is therefore essential to carefully read and become fully familiar with
the following safety regulations. Keep this booklet in a safe place after it
has been read.
- It is strikly forbidden to use converter in satured environments with explosion risk.
- Keep the work area in a clean and orderly condition. Untidy areas and environments
encourage accidents.
- Before beginning work, check that the motor-driven vibrator and the machine on which
it is installed are in a perfect condition. Check that operation is regular and that there
are no damaged or broken parts. Any parts as are damaged or broken must be repaired
or replaced by competent and authorized personnel.
- Repairs made by persons as have not been authorized by the Manufacturer shall void
the guarantee. In this case, the user will also risk operating with unsafe and potentially
dangerous equipment.
- Never touch the motor-driven vibrator whilst it operates.
- Only proceed with inspections, checks, cleaning, maintenance and replacement of
parts when the motor-driven vibrator and machine are off and with the plug removed
from the current socket (Fig. 2).
- Children or unauthorized, inexpert persons or those in poor conditions of health are
forbidden to touch or use the motor-driven vibrator.
- Check that the electricity main complies with the standards in merit.
- When installing the equipment, check that the power cable is of a very flexible type
and ensure that the machine has been correctly grounded (Fig. 3).
- Check that the current socket is suitable and that it conforms to the standards in merit,
with automatic switch and built-in protection.
- Any electric cable extensions must have plugs/sockets and cable with ground
connection as established by the standards in merit.
- Never stop the motor-driven vibrator by detaching the plug from the current socket
and never pull the cable to detach the plug from the socket.
- Periodically check the condition of the cable. Replace it if it is damaged. This operation
may only be carried out by competent and authorized personnel.
- Only used approved and marked extension cables.
- Protect the cable against high temperatures, lubricants and sharp edges. Never twist
or knot the cable.
- Never allow children or unauthorized persons to touch the cable when the plug is
inserted.
- If installation of the motor-driven vibrator on a machine causes the sound level
estabilished by the laws in force in the country of use to be exceeded, the operators
must take adequate precautions by wearing ear muffs, for example, in order to
safeguard their hearing.
- Even though the motor-driven vibrators have been designed to function at a low
operating temperature, their temperature may reach high values in particularly hot
places, this being caused by the environment itself.
ENGLISH
Always wait until the equipment has cooled before working on the motor-
driven vibrator (Fig. 4).
- Only use authorized tools as described in the instruction manual or the Manufacturer's
catalogues. Failure to comply with this regulation could mean that the users work
with unsafe and potentially dangerous equipment.
- Repairs must only be made by persons authorized by the Manufacturer.
The Manufacturer is, however, at your complete disposal for immediate
and accurate technical assistance and for everything else as may be
required to ensure the correct operation and maximum efficiency of the
motor-driven vibrator.
SECTION 3
Handling and installation
The motor-driven vibrator may be supplied without packing or palletized, according to
the type and size.
To handle the palletized unit, use a lift truck or forked transpallet. Only use the lifting
eyebolts or brackets if the unit is not packed (Fig. 4A).
If the motor-driven vibrator must be stored for a long period of time (up to 2 years at most),
ensure that the storage area is at ambient temperature (not less than +5°C) with a relative
humidity of not more than 60%.
Take the greatest care to prevent impact or vibrations when handling
the unit. This will prevent damage to the rolling bearings.

3.0 BEFORE INSTALLATION

Before installation and if the motor-driven vibrator has been in store for a
long period of time, remove the side covers protecting the weights (Fig. 5)
and check that the shaft is free to turn (Fig. 6).
For ball bearing equipped vibrators, after 3 years of stock, it is
necessary to replace the complete bearing.
After having kept for more than two years on stock the roller bearing
equipped vibrators it is necessary to regrease them due to the
suggested quantities (see pag. 70).After 3 years of stock, it is
necessary to replace completely the grease.
It is essential to test each individual phase to earth and between phases.
To conduct this test use an Megger insulation tester at a test voltage of
approximately 2.2 Kv, for not longer than 5 sec. between phases and 10 sec.
between phase and earth (Fig. 7).
If faults are detected, the electric rotary vibrator must be sent for resetting to an
ITALVIBRAS After-Sales Centre.

3.1 INSTALLATION

ITALVIBRAS vibrators can be installed in any position.
The vibrator must, however, be rigidly fixed to a perfectly flat structure (Fig. 8) with bolts
(type 8.8) DIN 931 or 933 and nuts (type 8.8) DIN 934, able to bear high clamping torques
(Fig. 9). Use a torque wrench (Fig. 9) regulated according to the following «Technical
Features» Tables (to page 66).
The bolt diameter must correspond to that indicated in the above mentioned Table, in
relation to the vibrator in question (to page 66).
It is also essential to check that the bolts are fully torqued. This is particularly necessary
during the initial operative period.
Remember that most faults and breakdowns are due to irregular fixing or
bad torquing.
Attention: Check the tightness again after a brief period of
operation.
The electric rotary vibrator must be connected to a steel safety cable of suitable
diameter and length. This must be able to sustain the vibrator following accidental
detatchment, up to a maximum dropping distance of 15 cm (Fig. 10).
