Main Implement Pumps (1) Adjustment screw for constant horsepower flow control for upper pump. (2) Adjustment screw for constant horsepower flow control for lower pump.Adjust the flow of the upper pump by turning screw (1). Loosen the locknut that holds the screw. Turn screw (1) clockwise in order to increase the output flow of the pump. Turn screw (1) counterclockwise in order to decrease the output flow of the upper pump. Tighten the locknut.Adjust the flow of the lower pump. Loosen the locknut that holds screw (2). Turn screw (2) clockwise in order to increase the output flow of the pump. Turn screw (2) counterclockwise in order to decrease the output flow of the lower pump. Tighten the locknut.Adjustment of the Maximum Output Flow of the Pump
Illustration 3 g00789643
Main Implement Pump (3) Adjustment screw for upper pump. (4) Adjustment screw for lower pump.Adjust the maximum output flow of the upper pump.
Loosen the locknut.
In order to adjust maximum output flow, turn the screw. Turning screw (3) clockwise will decrease the maximum output flow of the pump. Turning screw (3) counterclockwise will increase the maximum output flow of the upper pump.
Tighten the locknut.
Adjust the maximum output flow of the lower pump. Use screw (4) instead of screw (3). Repeat Steps 1 through 3.
