Stretching the driving belts:
Open the door on the right (72) and stretch the driving belts by using the regulators
(50) so that, if you press the belt with a finger, its lowering does not exceed its
thickness. When you have to replace the driving belts, please loosen the regulators
(50) so that the belts can come out from their seating. Replace the worn belts and
stretch them as previously described. Assemble everything back together.
The driving belts on the R 500 tractor model are SPB 1800.
Checking the height of the driving roller
We suggest you to make sure, by looking inside the loading hopper, that between the
driving roller (54) and the apron conveyor (145) there is al least 5mm backlash.
Should you adjust their height, please use the rules (51) located on the sides of the
machine when opening the doors.
Checking the flexible coupling
To verify the wear of the coupling (112), please open the left door (73) and make sure
that there is no backlash between the two parts of the coupling. If so, you have to
replace the coupling. To replace it, please loosen the two dowels (29); disassemble
the pump supporting structure (111) by unbolting the four nuts (2). Without taking
the pump out, take the coupling out. Replace it with a new one and assemble
everything again following the inverse procedure.
Cleaning of the air / oil exchanger
To get the maximum results out of the hydraulic system, we suggest you to clean the
splits with compressed air or water, always taking care of directing the jet parallel to
the splits in order not to damage them. It is of the utmost importance that the electric
engine is unplugged from the voltage during this operation and it is well protected
against the jet.
Levels
Hydraulic oil: It is possible to check the level of the hydraulic oil through the level
indicator located on the oil tank. If you need to top up, please use the SAE46 oil type.
Oil for reducers and multiplier: Check the oil level in the reducers through the
appropriate level caps (SAE 80w-90 kind).
Daily maintenance
Clean the machine outside.
Make sure that the screws and the nuts are tightened properly.
Make sure that all protection devices are sound and steady on the machine.
Clean the apron conveyor inside.
Clean the air/oil exchanger
Check the intactness of the driving belts.
