OPERATION PROCEDURES (Continued)
d. Watch the temperature gage. As the temperature increases or decreases, readjust the flowmeter to the correct
flow meter setting. Find the new flow setting in the performance data graph.
e. Watch the nozzle pressure gage. If the nozzle air pressure gradually increases, the air holes may be plugged
with oil or partially coated with oil residue. Remove the nozzle air cap and rinse it with acetone.
f. Turn the solenoid valve switch OFF when driving near automobiles and buildings. The insecticide can cause
spotting to paint finishes. The commercially acceptable operating distance from automobiles and buildings is 100 feet.
g. Turn the solenoid valve switch OFF when the vehicle is stopped.
h. Only spray insecticide aerosol when wind conditions are less than 10 mph.
i. Do not spray insecticide aerosol during the hot periods of the day. The heat rising from the ground will carry the
aerosol away. The best time to spray is early morning or late evening when the temperatures are cooler.
a. Shut the solenoid valve switch OFF and stop the truck.
b. Shut the aerosol generator ignition switch OFF.
c. Close the fuel tank valve.
d. Park the vehicle on a flat area or facing uphill.
e. If the aerosol generator is going to be stored for less than three days, flush the fluid lines only.
