The flow meter (item 3) provides an input to the Toro
Electronic Controller (TEC) regarding the spray system
flow that is available to the boom spray valves. If the flow
meter is being replaced, calibrate the flow meter after in-
stallation (see Flow Calibration in the machine Opera-
tor’s Manual or Software Guide).
IMPORTANT: Make sure to remove and neutralize
chemicals from spray components before disas-
sembly. Wear protective clothing, chemical resist-
ant gloves and eye protection during repair.

1. Park machine on a level surface, stop spray pump,
stop engine and engage parking brake. Remove key

ward the boom section valve assembly.

tion valve assembly from machine (see Spray Control
