Cleaning the Sprayer
Clean the spray system after each spraying session.
Important: Always empty and clean the sprayer
immediately after each use. Failure to do so may
cause the chemicals to dry or thicken in the lines,
clogging the pump and other components.
To properly clean the spray system:
• Use three separate rinses.
• Use a minimum of 5 gallons (19 L) for each rinse.
• Use the cleaners and neutralizers as recommended
by the chemical manufacturers.
• Use pure clean water (no cleaners or neutralizers)
for the last rinse.
WARNING
Do Not clean spray nozzles by mouth or blowing
through them. Swallowing or inhaling chemicals
could cause serious injury or death.
Replace all worn and damaged nozzles.
Make sure nozzles are installed correctly.
1. Drive the machine to a designated cleaning area.
2. Stop the spreader-sprayer on a level surface, leave

3. To drain the tank, remove the tank drain valve
plug. The tank drain is located on the left side of
