Calibrating The Sprayer Flow - Exmark Z Turf Equipment Z-SPRAY Operator's Manual

Operation
Important: If you used wetable powder
chemicals, clean the strainer after each tank
rinse.
1. Supply valve
17. Repeat steps 5 through 16.
18. Using a garden hose, spray off the outside of the
sprayer tank with clean water.
Note: Do Not use a power washer to clean the
machine. The high pressure water may force
residual corrosive materials into spreader-spreader
components.
19. Remove the nozzles and clean them by hand.
Replace damaged or worn nozzles.
20. Allow the spreader-sprayer to completely dry
before the next use.

Calibrating the Sprayer Flow

Note: Before using the sprayer for the first time,
change nozzles, or as needed–calibrate the sprayer
flow and speed.
Note: Refer to the chemical product label for
application rate recommendations.
The method to calibrate the sprayer flow involves
driving a preset distance, recording the time, and then
measuring the amount of liquid applied during that
time.
