1.4 WARRANTY LIMITS
Turbosol Produzione S.p.A. machines are covered by a warranty for a 12 (twelve) month period or 1000 hours of work -
whichever occurs first - starting from the delivery date of the machine to the Final user and, however, not beyond 18 (eighteen)
months from their shipment date. The machine's delivery date to the Final user must be reported on the warranty certificate that
must accompany all newly manufactured machines. The warranty is only valid if the manufacturing company receives the
warranty certificate card, duly completed and signed by the purchaser, within 30 days from the machine delivery date. The
warranty covers any manufacturing or material defects. The goods supplied by Turbosol Produzione S.p.A. but manufactured
by third parties are covered by the warranty granted by the latter to Turbosol and that is applied to the Final user. Only the
Manufacturing Company and the Organisations expressly authorised by it can intervene in the event of faults during the
warranty period. The faulty pieces must be sent to the Manufacturing Company ex works, which commits to gratuitously repair
or replace those parts that, at its indisputable judgement, show quality defects. The faulty pieces must be sent to the

2.2 TYPE OF MACHINE
The T20X is a stationary machine for the transportation, distribution and projection of mortar. It is used autonomously and
independently and is only intended for professional operators.
2.3 OPERATION
The premixed bags (or conglomerate individual components) are manually loaded inside the tipping mixer, in which the mixture
is created with the right consistency to be pumped. Once ready, it is unloaded into the hopper by mechanically tipping the
tipping mixer.
The worm pump transfers the conglomerate through the conveying pipe to the place of projection or distribution. Projection
takes place thanks to a gun.
The main machine commands are grouped on its structure, in a position that allows the operator maximum efficiency in
preparing the mixture.
Beneath the bonnet are the machine integrated system, such as the internal combustion engine, electrical, hydraulic,
pneumatic and water systems.
The operators generally involved are two and occupy different workstations: the first and main operator is on the machine, in
charge of its running and supervision and creation of the mixture; the second operator (generally working at the same time as
the first) is in charge of the distribution or projection on the place intended for such activities.

3.3 RECIPIENTS OF USE
The machine was designed to be operated by the following professional figures:
OPERATOR
Person trained and informed on residual risks, who deals with the supervision and running of the machine. Must be trained on
the position of all control and safety commands. The operator must only work with active safety conditions. The operator is also
trained to perform tooling tasks within the dangerous area, with the exclusive use of their hands or special tools provided with
the machine. The operator must also know the user requirements of cement conglomerates provided by manufacturers through
technical and safety data sheets of the product.
There are generally two operators involved and occupy different workstations:
- the first and main operator is on the machine;
- the second operator (generally working at the same time as the first) is in charge of the distribution or projection on the place
intended for such activities.
The operators must be able to communicate during the processing phases.
The main operator tasks are:
- possible machine transportation to the site;
- selection of the workplace according to the service conditions;
placing the machine;
- machine tooling for the work phases (piping connection, refuelling, etc.) and preliminary checks before starting the machine;
- running the machine;
- creating the mixture;
- machine supervision during the work phases, including cleaning;
- cleaning the machine;
- routine maintenance of the machine.
A second operator is required during the distribution and projection of the mortar, whose tasks are:
- distribution or projection of the mortar;
- supervising the distribution or projection area.
Additional personnel required for the performance of the work must be trained on the operations to be
performed and informed on relevant residue risks.
With reference to figure 3-1, the areas that can pose risks for the operator (dangerous areas) are:
A - work and tooling area around the machine. This is also the area occupied by the operator during cleaning of the machine.
During tooling the fixed guards are closed and locked, the mobile guards and closed or open with machine off. During the work
phase under manual operating conditions, the fixed guards are closed and locked and the mobile guards closed.
B - area in which the mortar conveying pipes and pneumatic piping were laid;
