MERCURY OPERATOR'S MANUAL
1. Dilute the remaining spray liquid in the tank with at least 10 parts of water and spray the liquid
on trees that have already been treated. It is advisable to increase the forward speed (double it if
possible) and reduce the pressure.
2. Select and use the appropriate protective clothing, such as rubber gloves, face mask, welling-
ton boots, etc. Select an appropriate detergent for cleaning and a deactivating agent if necessary.
3. Wash the outside of the tractor and sprayer with detergent.
4. Clean the suction and pressure fi lters. Take care not to damage the mesh. Replace.
5. With the pump running, rinse the inside of the tank, remembering the tank roof too. Rinse and
operate all the components that have been in contact with the chemical product. Before opening
the nozzles make sure that the machine is on crops or the soakaway.
6. After all the liquid has been emptied out, stop the pump and fi ll at least 1/5 of the tank with clean
water, and add detergent and/or deactivating agent, for example washing soda or triple ammonia.
7. Start the pump and operate all controls so that the liquid is distributed to all the components.
Leave the nozzles until last.
8. Drain the tank and let the pump run dry. Stop the pump as soon as it becomes empty. Rinse
the inside of the tank.
9. Fit the fi lters and nozzles and store the sprayer. The solvents used in the chemical products
react very strongly. Store the sprayer with the tank lid removed.
Check periodically for corrosion and react accordingly.
Unforeseen interruptions
If an application must be interrupted unexpectedly, for example because of bad weather, and there
is still liquid remaining in the tank it is advisable to fl ush the pump, operating unit and tubes.
Close the nozzles and stop the PTO. Close the suction fi lter valve and open the fi lter. Start the
pump and immediately run clean water through the suction hose that leads to the pump and open
the nozzles. Continue until clean water is coming through the nozzles. Stop the pump and re as-
semble the suction fi lter.
