Auto Calibrating Sprayer

The SPRAYSTAR ™ system will automatically calibrate itself in order to provide an optimal control for a particular situation.

The only time auto calibration is needed is when the A and B values do not lie within their ranges or when one of the following has been replaced:

• solution pump/hydraulic motor assembly
• proportional valve
• hydraulic pump

NOTE: The A and B ranges are:

A = 2000-4000

B = 6500-9000

To auto calibrate the sprayer:

NOTE: Solution pump switch should be turned off to perform this procedure.

1. Operate engine at full throttle and warm hydraulic fluid temperature to normal operating range.

2. Fill solution tank with water or solution. Set solution control valves on valve manifold to spray position.
