7. Maintenance
7.10.
Wheel’s Axle
Grease every 250 hours the wheel’s axles with consistent grease. To this
purpose, take out the A cap and fill with grease the internal cavity,
replacing again the protective cap.
7.11.
Tyres
The trailed sprayers are provided with tyres with measures indicated in the board of the
descriptions’ chapter.
The following rules of maintenance must be respected:
• Verify the inflated pressure of the tyres before any season start up and with certain
frequency.
•
Check that the bolts that hold the wheels rim are well tightened.
•
Check the condition of the wheels, in order to detect possible fissures or deformation of this one
which could cause a puncture or explosion of the wheel, with the ensuing danger that this
implies.
•
Avoid the excessive accumulation of mud in wheels as well as in axles.
7.12.
Winter Storage
Before storing your machine for the winter pause, it is advisable to give it a special care:
•
Make sure that the tank is empty and free of wastes.
•
Replace the joints and the possible losses.
•
In areas where the temperature is prone to descending below 0°C, fill the tank with 50 liters of
water mixed with antifreeze and set the pump on working with the jets closed, until being sure
that the pump and all the circuit is full of antifreeze.
•
Leave the tank with the charging mouth uncovered to avoid possible accumulation of gases.
•
After a full cleaning of the machine, check the paint of the frame; repair the rusted places, as
the phytosanitary products accelerate corrosion in damaged areas.
•
Start a general greasing process and change the oil in the pump and in the gear box.
•
Disassemble the manometer of pressure and keep it away of frosts and in vertical position.
•
Keep the machine in a safe, aired and closed place.
•
Make sure that the pressure regulation valve is in “zero” position.
•
Check that all protections of the machine are in perfect condition.
•
All the electrical connectors should be kept in plastic bags to protect them from humidity, dirt
and corrosion.
•
Disassemble the control box if the tractor has one, and keept in a dry and clean place.
7.13.
Preparation of the machine to use it after its storage
After the storage period, the machine should be arranged to start the job of the new season with
guarantees. For a correct start, follow the next steps:
• Assemble again the manometer of pressure. Replace the old teflon.
•
Connect the machine to the tractor including electrical wires and hydraulic adapters.
•
Check the brake.
•
Empty the tank until no waste of freeze remains.
•
Rinse completely the liquid circuit with clean water.
•
Fill in the tank with clean water and check all fonctions.
