Adjust as necessary.
when the pressure control solenoid valve is force-driven
at 50% duty. If the K/D brake apply pressure is not within
the specified limit, make readjustment by using the reduc-
ing pressure adjustment screw.
Standard value: 275 kPa (39 psi)
Oil pressure change for
each turn of adjusting screw: 22 kPa (3 psi)
pressure is in the range 360-480 kPa (51-68 psi).
Caution
This adjustment should be made with oil temperature
The adjustment made with high oil temperature could
result in improper adjustment due to a line pressure
drop at idle.
