MICRONAIR AU8500 ULV TREE SPRAYER 

3.  The sprayer should be protected from rain and prolonged direct sunlight when not 

in use, either by leaving the machine under cover or by covering it with a 
protective sheet. 

 

 

7.2. Fan 

Gearbox 

 
The fan gearbox is filled with SAE 90 gear oil.  The oil level is shown in the oil level 
indicator at the side of the gearbox. 
 
The oil in the gearbox should be changed after the first 50 hours of use and every 
500 hours thereafter.  The oil capacity of the gearbox is approximately 1.5 litres. 

 

 

7.3.  Pump, Pipework and Filter 

 
The pesticide pump used on both the sprayer is a centrifugal pump magnetically 
coupled to an electric motor.  As the pump has a magnetic coupling there is no shaft 
seal to wear or leak.  The pump contains no user serviceable parts and should be 
replaced as a complete assembly. 
 
All hoses have a PTFE lining with a braided stainless steel outer covering and 
crimped end fittings.  Hoses cannot be repaired if they are damaged and must be 
replaced with the appropriate Micronair spare parts. 
 
There is a 50 mesh filter in the pesticide pipe between the tank and the pump.  This 
should be checked and cleaned after the first month (or 20 hours) use of the sprayer 
and then every three months or after each 50 hours of operation, whichever occurs 
first.  The procedure to clean the filter is as follows: 

1. CLOSE the 

Filter Isolating

 valve (2 in Fig. 1). 

2.  Place a shallow container with at least 0.5 l capacity under the bowl of the filter. 

3.  Unscrew the filter bowl and remove the filter screen. 

4.  Clean the filter screen and inside the inside of the filter bowl 

5.  Fit the screen inside the bowl and screw them back onto the filter body.  Do not 

over-tighten the thread. 

6. OPEN the 

Filter Isolating

 valve. 

 

IMPORTANT:  Wear gloves and eye protection when working on the pump, 
filter or pipework.  Re-use any clean pesticide drained from the system and 
dispose of any contaminated residues, cleaning cloths etc safely. 

 
 

7.4. Atomiser 

 
See Micronair AU8120 Atomiser Handbook for full maintenance instructions.
