Sprayer Cleanup

Before and after using Olympus herbicide, always complete a thorough cleaning of the spray tank, lines and filters. The following procedures are recommended:

  1. Drain the tank completely, and then wash out tank, boom and hoses with clean water. Drain again.
  2. Half fill the tank with clean water and add ammonia (i.e., 3% domestic ammonia solution) at a dilution rate of 1% (i.e., 1 Lof domestic ammonia for every 100 L of rinsate). Complete filling of the tank with water. Agitate/recirculate and flush through boom and hoses. Leave agitation on for 10 minutes. Drain tank completely.
  3. Repeat step 2.
  4. Remove nozzles and screens and soak them in a 1% ammonia solution. Inspect nozzles and screens and remove visible residues.
  5. Flush tank, boom, and hoses with clean water.
  6. Inspect tank for visible residues. If present, repeat step 2.
  7. Dispose of rinsing in accordance with provincial regulations.
