FAMILIARIZATION

OPERATOR CONTROLS

The standard configuration of the Guardian 55 ES 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.
