3. INSTALLATION 3.1. Installation on Vehicle The AU8115MS Sprayer can be installed on any vehicle with an open bed and an enclosed cab to protect the driver from the spray. The sprayer should be positioned as far to the rear of the vehicle as possible so that when the support frame is raised the atomiser projects behind the rear of the vehicle.
IMPORTANT: the engine is shipped without oil. OIL MUST BE ADDED before starting the engine 4. CONTROLS This section describes the main features and controls of the sprayer and gives a brief explanation of their functions. Further details will be found elsewhere in this manual.

6.4. Set the Flow Rate The flow rate from the AU8115MS can be controlled either by the use of an adjustable restrictor valve or by interchangeable in-line orifice restrictor plates. The orifice restrictor plates should only be used when the sprayer will remain set to a constant flow rate for a long period.

IMPORTANT: if using the flow control valve, it is essential to ensure that there are no orifice plates fitted. The position of the flow control valve knob can be fixed after adjustment by tightening the locking screw using the 2 mm hexagonal key provided in the tool kit.

6.5. Select the Correct Droplet Size The correct spray droplet size must be selected for the application. The factory settings for the AU8115MS are designed to produce the smallest possible droplet size. For some spray applications, however, it may be more appropriate to select a larger size of droplet.
After use, drain any remaining pesticide from the tank by placing the drain hose into a suitable container and opening the drain valve. Any unused pesticide must be kept in a closed container for future use or safe disposal. MICRON AU8115MS VEHICLE MOUNTED SPRAYER...

8.2. The AU8115MS sprayer is fitted with a robust blower fan which is designed to withstand ingestion of dirt and debris without damage. The fan and fan casing must be cleaned after every six months of operation or more frequently if the sprayer is used in dusty or dirty conditions.
If necessary, remove the sprayhead from the sprayer and remove the two screws holding the front and rear casings together. Slide the atomiser securing ring out of the casing. Remove the hose connector and atomiser securing nut and slide the atomiser spindle from the support ring. MICRON AU8115MS VEHICLE MOUNTED SPRAYER...
