Troubleshooting
LIFT CIRCUIT OPERATION TROUBLESHOOTING
PROBLEM POSSIBLE CAUSE TROUBLESHOOTING* SOLUTION
Planter raising uneven. Master cylinder leaking. Raise planter slowly until
master cylinder reaches
end of stroke. If master
cylinder is leaking it will lag
behind the slave cylinder,
causing the tire to squat
less. If planter settles when
hydraulic lever is released,
check assist cylinders. Check piston rephasing
valve for contamination.
Before removing rephasing
valve, measure set screw
setting by turning set screw
clockwise and counting
the revolutions until it
bottoms out. After cleaning
rephasing valve, bottom
the screw out and back it
out the same number of
revolutions as the original
setting.
Replace rephasing valve
and adjust as stated above
or replace piston.
Install seal kit.
Consult your Kinze Dealer
for leak testing and
rephasing valve adjustment
if necessary.
Slave cylinder leaking. Raise and lower planter.
As planter lowers, side with
leaking slave cylinder will
drop rapidly. Install wheel
lockups on master and
assist cylinders. Retract
slave cylinder and observe
which tire settles. If planter
settles when hydraulic lever
is released, check assist
cylinders. Check piston rephasing
valve for contamination.
