Preparation after off season storage
After a storage period the sprayer should be prepared
for the next season the following way:
1 Remove the cover.
2 Remove the support from the wheel axle and adjust
the tyre pressure.
3 Wipe off the grease on the hydraulic ram piston rods.
4 Fit the pressure gauges again (seal with teflon tape).
5 Connect the sprayer to the tractor including hydrau-
lics and electrics.
6 Check all hydraulic and electric functions.
7 Empty the remaining anti-freeze from the tank (If
used).
8 Rinse the entire liquid circuit of the sprayer with
clean water.
9 Fill with clean water and check all functions.

Troubleshooting
In cases where breakdowns have occurred, the same
factors always seem responsible:
•
Minor leaks on the suction side of the pump will
reduce the pump capacity or stop the suction com-
pletely.
•
A clogged suction filter will hinder or prevent suction
so that the pump does not operate satisfactorily.
•
Clogged up pressure filters will result in increasing
pressure at the pressure gauge but lower pressure at
the nozzles.
•
Foreign bodies stuck in the pump valves results in
these valves not closing tightly against the valve
seat. This reduces pump efficiency.
•
Poorly reassembled pumps, especially diaphragm
covers, will allow the pump to suck air, resulting in
reduced or no capacity.
•
Hydraulic components that are contaminated with dirt
result in rapid wear to the hydraulic system.
Therefore always check:
1 Suction, pressure and nozzle filters are clean.
2 Hoses for leaks and cracks, paying particular atten-
tion to the suction hoses.
3 Gaskets and O-rings are present and in good condi-
tion.
4 Pressure gauge is in good working order (Correct
spray dosage depends on it).
5 EC operating unit functions properly. Use clean
water to check.
6 Hydraulic components are maintained, clean and
free from leaks. Refer to the boom operator's manual
supplied with your sprayer documentation, either
FALCON or EAGLE PARALIFT Boom Operator's
Manual .
