Setting Mechanical Selective Control Valve for VACUMETER™-7810, 7720 and 7820 Tractors

IMPORTANT: If vacuum level cannot be fine tuned adequately with the 200 Series tractor SCV, the planter flow control valve can be used to adjust vacuum. The tractor flow control valve must be fully open when using planter control valve.

Set SCV control knob (A) to motor position (continuous detent). Flow control knob (B) will be used to control vacuum level, start with flow control low and work up. The flow control valve on the machine must be set to full open position.

SCV lever should be in forward position for running and "float" for off. The motor has an over-running check valve to protect seals if accidentally put in neutral.
