of components, placing, repair, etc.) insulate the machine as follows:
Stop the machine; Cut off electric supply; Make sure the machine is powerless and the complete lack of
residual energies: temperatures, bucket on the ground. Only one operator shall be responsible for the
execution of all these operations. Always use the protective equipment during installation, operation
and maintenance of the machine: Work gloves, Safety shoes, Ear muffs, and masks. On-site Ensure
sufficient lightening and space for maintenance works and the moving around of the personnel. Always clean the
ground, because dust, water, etc. make the ground become slippery and dangerous. Wear tight-fitting clothing. Do not
wear any jewellery or clothing that can get caught. Always use the protective equipment.
On the machine, before
starting the work Make sure the motor cooling grating is chipless and free of any dirt. The concrete mixers are
equipped with a magneto-thermal switch with minimum voltage release coil. In case the supply voltage does not comply
with the specifications or after a short-time cutoff , the minimum voltage coil will automatically cut off the supply voltage.
In such a case you must press the start push-button to restart the machine. The motor is equipped with an overload
protection; the motor stops in case of overheating. The motor is protected from inopportune starts after cutoff
.
All
Maintenance and assembling operations must be done, after having disconnected the power supply to the
machine.
The machine shall be kept turned off when it is not used. Always carry out a work cycle without material to
check good operation. Ensure the machine devices and the area in front of the drum are proper and free of obstacles.
Ensure all the safety devices, control devices and work devices are well positioned.
During operation Use the prescribed protective equipment. Never approach the moving and operating elements
with your hands, arms or other parts of your body. Remove rubble with an appropriate device and always with the
machine stopped:
never use your hands! In case of machine trouble, never work with the machine running, wait for
complete machine stop and finish the work cycle or stop immediately the machine. During the operation of the machine,
of its elements or of its accessories, it is strictly forbidden to remove any protection, like cases, barriers or other
protection and safety elements. Never modify switches or other safety and/or operating cycle control devices, because
such an intervention could seriously damage the mechanical elements of the machine and injure the health of the
operator. Pay attention to the operating and the moving parts. Do not climb or position yourself on or inside the
machine. In case of machine trouble, stop the machine with the emergency push-button and cut off the electric energy
supply until the trouble has been eliminated. It is forbidden to climb or sit on the machine.
During maintenance Before carrying out any maintenance work, insulate the machine as described at the
beginning of this chapter . In case of mechanical or electrical troubles, get in touch with the authorised personnel.
If the machine is out of service because of troubles, maintenance or repair works, place a sign and padlock the
main switch. Always use the protective equipment during repair and replacement of the machine elements.
All electric operations must be done by experienced and authorised personnel.
Never approach the moving and operating areas with your hands, arms or other parts of your body. Remove rubble with
an appropriate device (brush, wooden piece, etc.):
never use your hands! Regular maintenance of the mechanical and
electrical elements ensures a long machine life, best performances and a high safety factor. Periodically check proper
grounding, according to the standards in force. Before starting the machine, check the inside and outside of the
machine for possible tools or foreign matters and remove them. Safety signs :
Caution electrocution hazard Ground connection point
(on components of the electric system)
Caution moving parts Direction of motor rotation
(next to the drum)
Wear ear protection
Anchorage / hoisting point
(ear muffs or plugs)
(On the machine there are instructions about residual hazards, follow these instructions.)
8. MAINTENANCE
The machine does not require any particular maintenance work.
The technical solutions and the components installed on the machine reduce the maintenance works
at the minimum. However, we recommend to carry out a series of operations, which aim at ensuring
safety, liability and efficiency of the machine for a long period of time.
Before performing maintenance work, switch off and disconnect the machine from the power
supply (main switch). During maintenance work, place a special sign on the electric panel and on the
machine to highlight this status. Never make any modifications to the machine. Use the protective
equipment during maintenance work: work gloves, safety shoes, masks, and goggles.
8.1
Preventive (routine) maintenance To be carried out every day at the end of the work : Clean the
work areas, the drum and the operating mechanisms. Blow away the dust on the machine and on the motor protection
grating with compressed air. Remove any deposits from the work and support surfaces. Check the supply cable and
make sure that it is undamaged. Periodically check the hydraulic oil level, the belts and replace them, if necessary.
Oil is a special waste and must be disposed of according to the laws in force.
Clean the ground and remove any rubble. To be carried out every week: Check locking of the
mechanical components. Check protections and ensure their good operation, replace if necessary.
Check the oil level of the drum reducer and the scraper shovel reducer, if necessary fill up with SAE 150 oil. Periodically
lubricate the rotation pin of the bucket and the pins of the lower rollers. Lubricate the crown gear with viscous grease.
