The sweeper may be attached to the tractor if it does not cause problems and does not require
additional tools. Check the proper connection of all elements.
When connecting the hydraulic hoses to the tractor, ensure that they are not twisted, without
loops and protected from damage.
To ensure the optimal operation of the sweeping machine:
The sweeper requires a hydraulic circuit with backflow and a quick connect coupler.
Checking the turning parts (hydraulic motor, cleaning brush shaft) regularly (at least
every 8 working hours).
WARNING!
Strictly follow the guidelines on fixing points
5.2 CONNECTING THE SWEEPING MACHINE TO THE HYDRAULIC
SYSTEM
Remove the plugs of the quick connect couplings from the safety catches (or pull out the
attachment tips) and connect to external couplings on the tractor's hydraulic system. When
connecting the hydraulic hoses, make sure the hoses are not bent and are protected against damage.
5.3 TESTING THE SWEEPING MACHINE
The sweeping machine must be tested:
Before starting the sweeper operation
Periodically (at least once a month)
After repair works have been carried out
The user of the machine must ensure that the hydraulic hoses are replaced after a certain period
of time, even if any defects are not visible. The hydraulic hoses should not be used for more than 6
years. Date of production and permissible dynamic pressure are indicated on the hose.

5.4 WORKING WITH THE SWEEPING MACHINE
After checking the attachment of all safety devices and hydraulic connectors, you may start
working with the sweeper.
The sweeper working speed depends on the type of the surface to be cleaned and the amount of
garbage (but may not exceed 10 km/h).
When operating the sweeper:
With two wheels, observe that during operation the sweeping machine rolls on the wheels
Observe that the loader does not press the sweeping machine with its own weight
The hydraulic hoses must be connected in a way allowing the shaft to rotate in the
required direction
The supporting wheel sand garbage collection box may not obstruct the shaft
Before sweeping, check the shaft pressing to the ground. The shaft is pressed by
adjusting the supporting wheels (Fig. 4). If the sweeping segments are worn, the
supporting wheels must be reinstalled to ensure that the sweeping segments are in contact
with the surface to be cleaned.
Note! When the shaft is being reassembled, ensure that the axle is not bent. The hydraulic system
must be repaired by specialist workshops. In a daily work with the sweeping machine, observe its
safe condition.
