Amazone UX Super service schedule

1. With the pump stopped and level, check the oil is visible at the mark on the pump.
2. On the hitch drawbar the pump sits at a slight angle, so take the reading as an average.
3. If the oil is not at the mark, take off the cap and top up with 20W-30 branded oil or 15W-40 multigrade.
4. Foam or cloudy oil means a damaged diaphragm: stop and have it checked.

Tools: Funnel, Rags

1. Look over the machine for obvious faults and leaks.
2. Check the hydraulic oil filter indicator (hydraulic fold) and replace the element if needed.
3. Pump clear water around for a few minutes after use, and rinse the tank and filters.
4. Check the nozzles, drain the air reservoir, and check the tyre pressures weekly or every 50 hours.

Tools: Hose, Gloves

1. Wipe the nipples and gun clean first so dirt is not pushed in. Push out the dirty old grease and replace it.
2. Grease the drawbar bearings (2 points) and drawbar eye every 50 hours.
3. Grease the support leg cylinder (2 points) and the parking brake cable, pulleys and spindle every 100 hours.
4. Grease the other nipples to the chart on the machine. No grease or oil must get into the brake.
5. In winter grease the driveshaft guard tubes so they do not freeze solid, and the driveshaft joints.

Tools: Grease gun, Rags

1. Check the brake lines, hoses and coupling heads for damage and corrosion, and the joints are secure and free.
2. Test for leaks, check air reservoir pressure and brake cylinder pressure, and check the lining wear and brake settings.
3. Check the parking brake holds when applied.
4. Check the wheel hub bearing play and tighten the wheel nuts to 510 N·m. Leave brake adjustments to a trained workshop.

Tools: Torque wrench

1. Clean the line filters in the nozzle lines and replace any damaged filter insert.
2. On drawbar-type pump drives press the belt with a 75 N test force: the deflection must not exceed 14 mm at 540 rpm drive or 16 mm at 1,000 rpm. If it does, move the pulley in its slots to tighten.
3. Check the boom for cracks and the folding hinges for wear.

Tools: Soft brush, Tension gauge

1. Take the pump off, take off the filler cap and turn the pump upside down.
2. Turn the drive shaft by hand until all the old oil has run out. You can also use the drain screw, but some oil stays in the pump.
3. Stand the pump on a flat surface and turn the shaft left and right while slowly filling with new oil. It is full when the oil shows at the mark.
4. Check the level again after a few hours of work. Dispose of old oil properly.

Tools: Drain tray, Funnel, Rags

1. Do one piston at a time and finish it before starting the next. Swing the piston up so the pump oil does not run out.
2. Look at the valve seat, valve, spring and guide for damage and wear. Replace damaged parts and fit new O-rings.
3. Tighten the valve nuts crosswise to 25 N·m (BP 160-185 pump) or 20 N·m (AR 250-280 pump); check your handbook for the AR 185.
4. Check every diaphragm and replace all of them if any is swollen, split or porous.

Tools: Torque wrench, Spanners

1. Calibrate the flow meter and set the return flow meter as the handbook describes.
2. Check the output of each nozzle against the table and replace those that are worn.
3. Check the pump output and pressure.
4. Check the spray pattern across the boom.

Tools: Measuring jug, Stopwatch, Pressure gauge

1. Clean the machine thoroughly while the tank is empty and drain the last of the liquid.
2. Run the pumps slowly and pump air until no liquid comes from the nozzles.
3. Open the drain tap on the suction side and the distribution valve on the pressure side, move the valves through all positions and close them again.
4. Remove one diaphragm valve from a nozzle body in each boom section so the nozzle lines empty.
5. Take out and clean the suction and pressure filters.
6. Take off the pump pressure hose so the water drains away, and run the pump for about half a minute until nothing comes out.
7. Cover the pump pressure connection, grease the driveshaft joints and the guard tubes, and change the pump oil.
8. Drain the hoses on the induction bowl and the injector, and empty the rinse water tank by loosening the union nut.

Tools: Hose, Grease gun
