Machine Operation
VACUUM FAN MOTOR VALVE bLOCK ASSEMbLY
A pressure relief valve in the hydraulic circuit prevents build up of oil pressure over 35 PSI in case drain line when
vacuum fan motor is operating. This valve will vent oil outside valve block through a drain hole in the aluminum valve
block. This can occur whenever case drain is improperly connected or pressure in motor circuit builds.
See “Hydraulic Diagram - Vacuum Fan Motor System” in Lubrication and Maintenance section.
Valve block contains a check valve that prevents vacuum fan from operating in wrong direction if pressure is applied to
return side of motor and allows fan to coast to a stop when tractor hydraulic control is returned to neutral position.
NOTE: Fan turns at a reduced speed If reverse pressure is applied.
DIGITAL VACUUM READOUT
Digital vacuum readout is incorporated into Kinze Vision and Cobalt displays. Refer to their operation manuals for
instructions.
Kinze EdgeVac seed metering system includes seed meters, seed discs, and an air system consisting of a hydraulic
driven vacuum fan which draws air through manifolds, hoses, and seed meters on each row unit.
WARNING
Moving fan blades can cause amputation or severe injury. Never
operate vacuum fan with cover removed.
The analog vacuum or pressure gauge connects directly to the
EdgeVac (vacuum) or ASD (pressure) manifold and is teed into
the digital sending units.
Only adjustment is to “zero” needle with no vacuum or
pressure present. If there is a significant difference between
gauge and a reading taken at meters, a different manifold
location should be found to connect hose to gauge and digital
sending unit.
ANALOG VACUUM OR PRESSURE GAUGE
Analog gauge
EDGEVAC SYSTEM
NOTE: Analog gauges are identical EXCEPT for plug and hose barb locations in side of gauge housing.
DO NOT connect EdgeVac or ASD hose to wrong gauge. Check plug and hose barb installation if readout is
erratic or appears inaccurate.
