FAMILIARIZATION
OPERATOR CONTROLS
The standard configuration of the Guardian 70ES incorporates manual controls of the engine
and the spray on/off. Optional electrical remote spray on/off is available by using a 12-volt
electric solenoid valve in place of the manual spray ball valve to control the flow of chemical to
the nozzle. This remote control device plugs into a "cigarette" lighter or accessory port of a
vehicle to provide 12 volts and a simple toggle switch opens the solenoid valve so the operator
can gain more distance between him/her and the machine.
AIR PRESSURE GAUGE
The air pressure gauge has a pressure range from 0-150 psig. When
the engine is running and manual throttle adjusted to the desired
engine RPM, air pressure is most often the overriding factor in
assuring correct atomization of a given flow rate. Air pressure is
measured through the copper tubing from the air compressor
discharge port.
