MAINTANCE AND STORAGE AFTER SEASON
When the spraying season is over, find some time and prepare the spraying appliance for storage.
Before storing the appliance, thoroughly clean the inside and the outside of the sprayer (regulator,
pump, sieves, selection valves, nozzles, etc.). When the cleaning is done make sure that there is
no water left in the valves, the filters, the pump, the nozzles, etc. Do not maintain the sprayer until
it has not been thoroughly cleaned.
13.1
Hoses
Check the tightness of all hoses and hose junctions. Replace damaged hoses with new ones. A
damaged hose cost you a lot of time during spraying.
13.2
Surface protection
Some sprays contain solvents with adverse effect on zinc. Remove the rust from the part where
the zinc coating is damaged and apply a new layer with a zinc spray.
13.3
Reservoir
Make sure that there are no rests of insecticide inside the reservoir. Chemical agents must not stay
in the reservoir for a long time, since they can fast shorten the durability of the reservoir and other
parts. Make sure that the outflow valve is opened.
13.4
Pressure regulator
Protect the pressure regulator against moisture and dust. It is recommended to grease moving parts
with WD-40 or oil. There are further instructions about the maintenance of the regulator in chapter
10.5.
13.5
Pump
After every season, thoroughly clean the inside and the outside of the pump and prepare it for
storage. Check the quantity of working hours and, if necessary, repair the pump (oil change,
membrane change, sealing change, etc.) or at least check the oil level, the sealing, etc. This is the
most appropriate time of the season to perform some maintenance work. If you are not sure
whether or not you can repair the pump on your own, leave the work to an authorized expert. You
can find the description about maintenance work in the chapter 11.
13.6
Multiplier gearbox
After each use, check the oil level and check for potential leakage. If you notice oil stains, you
must perform a service. Pay attention to unusual sounds during operation.
13.7
Drive/cardan shaft
It is very important that the safety pin, which is attached to the head of the cardan shaft, is clean
and greased. This assures that the shaft is safe to use.
Check the protective cover, the functioning and the condition of the cardan shaft every 40 working
hours. Replace damaged parts with new ones.
