CONVERSION FACTORS ............................................................................ 22 1. INTRODUCTION The AU8000 Sprayer consists of a Micronair AU8000 sprayhead mounted on a knapsack mistblower. The sprayhead provides a narrow, easily controlled spectrum of spray droplets to ensure an even distribution of product with a minimum of wastage. Air from the mistblower rotates the atomiser and is then directed into the airstream which carries the spray safely away from the operator and ensures maximum swath width and penetration of foliage. The AU8000 sprayer is intended for use in agriculture, public health spraying, migratory pest control (locust, armyworm etc.) and in any other application where a safe, effective, portable sprayer is required. It can be used with conventional water-based chemicals (both solutions and solids in suspension) and with specialised ULV formulations. The unit is supplied with easily interchangeable restrictors for quick and easy calibration of output rate for all chemicals and application techniques. Regardless of chemical type or application rate, the AU8000 sprayhead ensures optimum coverage of the target with a minimum wastage of chemical due to incorrectly sized droplets or run-off. The AU8000 sprayhead is also available separately as a conversion kit for use with an existing mistblower. For satisfactory operation, the air output from the mistblower must be as shown in the specification below. 2.

ASSEMBLY These instructions apply both to AU8000 sprayheads supplied as part of a complete sprayer and to sprayheads supplied as conversion kits. The steps with numbers in square brackets [ ] refer to conversion kits ONLY and should be disregarded when assembling a sprayer supplied complete. There may be some minor differences when installing conversion kits on some models of sprayer. Parts are identified by their reference number in Fig. 5. [1.] Ensure that the mistblower is empty, clean and in good running order. [2.] Disconnect the chemical feed hose from any existing on/off valve or flow regulator. Leave the feed hose connected to the chemical tank. [3.] Remove the original spray nozzle and outlet, leaving only the flexible air duct attached to the blower. 4. Insert one end of the rigid air tube (19) into the inlet of the sprayhead so that 40 mm of tube is inside the casing. 5. Slacken both clamping screws of the handle and valve assembly (13). Slide the handle over the air tube with the handle angled towards the sprayhead. Position the handle with one clamp over the slotted inlet of the sprayhead casing and the other on the air tube. Tighten both clamping screws to grip both the sprayhead and air tube. 6. Temporarily insert the free end of the air tube into the f...
