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.

SCV lever must be in forward position for running vacuum and variable rate drive and be moved to "float" position to deactivate. The motor has an over-running check valve to protect seals when accidentally put in neutral.
