2. SCOPE AND IMPORTANCE OF THE MANUAL
This Manual, prepared by the Manufacturer, is an integral part of the batch feeder and must therefore
accompany it right up to its dismantling and must be easily available for rapid consultation by the
operators and Works Manager involved in the site operations.
If the machine changes ownership, the Manual must be handed over to the new owners. Before
carrying out any operation with or on the batch feeder, the workers concerned must have read this
Manual carefully.
If the Manual is lost, damaged or becomes illegible, download a copy from the TOREX® website and
check the date of the latest version.
The Manual provides warnings and indications concerning the safety standards for accident-prevention
at the workplace. However, and in any case, the various operators must strictly follow the safety
regulations that concern them as imposed by the standards in force.
Modifications, if any, to the safety standards, made over time must be duly implemented.
With the basic features of the machine remaining unchanged, the manufacturer reserves the
right to make modifications, if necessary, to organs, details or accessories considered to be
necessary for improvement of the product or for constructional or commercial requirements,
at any moment and without any obligation to update this publication promptly.

- Recover plastic parts (such as sealing rings, cover, etc.) and send these to collection centres.
- Send the remaining parts all made of steel to scrap yards.
At the end of the machine's life, drain the gear oil and send it to special collection centres; remove
the plastic parts (sealing rings) and send these to special collection centres; send the remaining
parts to scrap yards.
In case of demolition, separate the materials according to quality.

17. Possible problems
Minor problems can be solved without consulting a specialist. A list of the most common problems
with the possible causes and remedies is given below.
PROBLEM SOLUTION
• Check to make sure the switch setting is cor-

rect; set the correct activation threshold, if
necessary.
• Check the electric motor connections, and reset
if necessary.
• Check the state of the electric motor using the
instruments meant for the purpose and replace
it, if necessary. To carry out the operations
described above, follow the safety regulations

• Remove the material that caused the block,
after having created the appropriate safeties:
the machine must be certainly disconnected
from the power supply.
• Locate the material that caused the block, re-

18. Residual Risks

Although certain risks have been eliminated at the origin in the batch feeder design and construction
phase, certain ineliminabile residual risks still persist for which warning signs and instructions are
required for the operators and special measures have to be adopted in the use of the machine.
18.1 Mechanical hazards
Stability
Handling and lifting of the bacth feeder must be done according to the indications given in the Manual
(Chap.2 Section “TRANSPORT-WEIGHTS-LIFTING).
Risks due to surfaces, sharp edges and corners

Particularly in the maintenance steps, it is necessary to use personal protection equipment (cut-proof
gloves, protective clothing, safety footwear), to avoid injury due to sharp and cutting surfaces and
edges of certain components. (See Manual Chap.2 Section “WARNINGS” and “MAINTENANCE”)..
Prevention of risks due to moving parts.

In the correct installation of the batch feeder, all accesses to moving parts are closed: in this regard,
refer to the Manual (RV Manual, Chap.2 Sect. "WARNINGS" and "INSTALLATION").
The transmission unit is protected by a guard which must not be removed before the machine is set
in safety condition.
In the maintenance steps or in case of actions which may make the moving parts accessible, refer
to the procedures described in the Manual (Chap.2 Sect. ”MAINTENANCE”).
18.2 Risks due to Electricity
Make the motor connections according to the indications given in the Manual (Chap.2 Sect. ”ELEC-
TRICAL CONNECTIONS”).
The batch feeder is supplied with an electric motor without power cables for connection to the
mains.
During machine commissioning operations, the operator must take care to connect the cables cor-
rectly, carrying out the operations in complete safety as envisaged by the standards (CEI EN 60204-1)
regarding the use of electricity. It is important to ensure that the batch feeder body is connected to
the plant’s earth circuit to avoid risk of electrostatic discharges. The earthing connection must be
made by the installer.

18.3 Risks due to high temperatures
During the course of normal operations or maintenance or cleaning, the operator can come in contact
with parts having temperature exceeding 60°C, with the machine stopped.
The temperature level is, however, greatly conditioned by the batch feeder application conditions
(power absorbed by the motor, material conveyed, work cycle).
It is therefore the installer’s responsibility to place warning notices which (if the hazard exists) indi-
cate the hazard due to the presence of very hot surfaces and the obligation for the operator to use
personal protection devices, such as safety gloves.
18.4 Noise, Vibrations.
As indicated in the Manual, the User must carry out measurements with the batch feeder operating
with material.
The user and employer must respect the legal standards as regards protection from daily personal
exposure of operators to noise and, if necessary, prescribe the use of personal protection devices
(ear muffs, etc.) depending on the total noise level present in the individual work areas and the daily
personal exposure level for the workers.
The valve must also be stopped in case of abnormal noises or vibrations (Chap.2 Sect. “WARN-
INGS”).
18.5 Emissions of hazardous matter/substances
While carrying out operations involved in routine or extraordinary maintenance, cleaning or batch
feeder removal, the operator must use suitable personal protection equipment, especially, masks to
protect the respiratory tract belonging to a class suitable for the type of dust filtered, as well as gloves
or clothing.
For more details, refer to the relevant sections of the Operation Manual (Chap.2 Sect. ”WARNINGS”
and “MAINTENANCE”)
It is the installer’s responsibility to provide the necessary warning notices indicating that it is compulsory
for the operators to use the P.P.E. necessary and the potential presence of harmful substances.
