The flowmeter (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
flowmeter is being replaced, calibrate the flowmeter af-
ter installation (see Calibrating the Sprayer Flow in the
machine Operator’s Manual).
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.
Removal (Fig. 13)
1. Park machine on a level surface, stop spray pump,
stop engine and engage parking brake. Remove key
from ignition switch.
2. Disconnect wire harness connector from flowmeter.
IMPORTANT: Note the direction of the arrow on top
of flowmeter (Fig. 14). The arrow should point to-
ward the boom valve manifold assembly.
3. Support flowmeter and loosen clamps that secure
