To avoid chemical contamination, wear appropriate protective equipment including gloves
whenever maintenance is carried out; turn off the pump and depress the trigger on the spray lance
to dissipate any pressure.
After spraying is completed, drain unused chemicals from the tank. Rinse the tank with clean water
then operate the sprayer with clean water in the tank to clean out the pump, hose, and spray lance.
Do not leave chemicals in the tank as they may crystallize or form solids and block in pump, spray
lines, nozzle, or filters.
If heavy frosts are experienced, run the sprayer until the pump and spray lines are dry. This will
prevent water freezing in the pump and damaging the sprayer.
Warning! Dispose of unused chemical and water used for rinsing in a manner that will not endanger
people, animals, or the environment in accordance with local regulations and the handling and
disposal information available from the chemical manufacturer.

after use to avoid filters becoming clogged.
