Machine Operation
NOTE: Analog gauges are identical EXCEPT for plug and hose barb locations in side of gauge housing.
DO NOT connect vacuum or bulk fill hose to wrong gauge. Check plug and hose barb installation if readout is
erratic or appears inaccurate.
VACUUM FAN MOTOR VALVE BLOCK ASSEMBLY
A pressure relief valve in the hydraulic circuit prevents build up of oil pressure over 35 PSI (241 kPa) 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 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 displays. Refer to their operation manuals for instructions.
Kinze vacuum 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.
VACUUM SYSTEM
Moving fan blades can cause amputation
or severe injury. Never operate vacuum
fan with cover removed.
