CHECK VALVE (LIFT SYSTEM)
Check valves, located in valve block on right side of center post, trap oil flow in planter’s lift
system to keep toolbar level during field operation. Consult your Kinze Dealer for service.
CHECK VALVE (VACUUM FAN)
Check valve located in valve block below vacuum fan motor assembly operates as a return
line check to prevent vacuum fan motor reverse operation. Remove and inspect valve If
it does not operate properly. Check for foreign material and if O-ring is leaking internally.
Replace if defective.
RELIEF VALVE CARTRIDGE
Pressure relief valve located in valve block below vacuum fan motor assembly helps prevent
damage to vacuum fan motor by limiting pressure in the motor case drain line. It is set to open at
35 PSI. If valve fails to function properly, it should be removed for inspection. Check for foreign
material and contamination on valve and the seating area of valve body. Replace if defective.
SOLENOID VALVE
Solenoid valve consists of a chambered body with an electric coil actuated cartridge valve.
If solenoid or solenoids fail to operate, first determine if problem is electrical or
hydraulic. If valve is working properly, a click will be heard when solenoid coil is
energized and valve stem opens. If no sound is heard, check solenoid coil by touching
top of coil housing with a metallic object such as a pliers or screwdriver. If coil is
working properly, coil housing will be strongly magnetized when energized. If voltage
to coil is low it will be weakly magnetized when energized and no click will be heard.
Coil
FLOW CONTROL VALVE
Flow control valves should be adjusted for row marker raise and lower speed as part of
assembly procedure or upon initial operation. If valve fails to function properly or requires
frequent adjustment, it should be removed for inspection. Check for foreign material and
contamination on valve and seating areas of valve body. Replace defective components.
PRESSURE RELIEF VALVE
If pressure relief valve does not release tongue lock or function properly, remove valve from
valve block and check for foreign material or if O-ring is leaking internally. Replace if defective.
Cartridge
NOTICE
Connect hydraulic motor case drain to a case drain return line with zero pressure on tractor or hydraulic
motor will be damaged. DO NOT connect hydraulic motor case drain to SCV outlet. Contact tractor
manufacturer for specific details on “zero pressure return”.
PRESSURE REDUCING RELIEF VALVE
If wings do not properly stay to ground, plumb into butt end of cylinder to test psi. Proper
setting is 2000 PSI.
