First claim

The invention claimed is:

1. A fluid dispensing system comprising:
a pump having a speed control for controlling pump speed;
a dispensing device, comprising:
at least first and second control buttons remote from the pump, and capable of communicating with the speed control of the pump through a wire or radio frequency to adjust pump speed, one of said control buttons actuable to signal the speed control to increase the speed of said pump and the other of said control buttons actuable to decrease the speed of said pump;
a valve connected to the dispensing device; and
a trigger for actuating the valve; and

a maximum pump speed control potentiometer located on the pump, the maximum pump speed control potentiometer providing a maximum pump speed control setting and allowing the maximum pump speed setting to be adjusted, so that any adjustments of the pump speed by the speed control in response to the first and second control buttons of the dispensing device may adjust the pump speed control to a pump speed setting below or up to the maximum pump speed setting, but may not adjust the pump speed above the maximum pump speed setting.
