V. OPERATING INFORMATION

Solution Pump

The solution pump is a hydraulically driven centrifugal pump (fig. 5.25) with variable speed control. Engage the solution pump while at a relatively low engine RPM setting (1,000 RPM). Increase engine RPM slowly and maintain full recommended throttle RPM for field operation. To activate the solution pump, push the solution pump lever forward (fig. 5.26).

NOTE:

DO NOT allow the pump to continue running when the boom switches are turned off. Failure to do so will generate over-heating and cause severe pump damage and void the warranty.

Solution Pressure Gauge

The solution pressure gauge (fig. 5.27) gives the operator a constant visual display of the amount of solution being applied (measured in PSI). The pressure (as determined by the monitorcontrolled butterfly valve) will vary according to ground speed. If applying solution manually, the solution pressure gauge visually informs the operator of needed manual adjustments.
