1.6.2 CHECK FOR PRESSURE OF HIGH
PRESSURE RELIEF VALVE

sure gauge (250 ~ 300 kgf/cm
2
) between the hydraulic
hose and PH port using the adapter.
2. Put the range shift lever to the "Neutral" position and
start the engine. When the engine speed reaches ap-
prox. 2,800 rpm, maintain that speed.
3. Push the power steering lever to the left or right as far
as possible to measure the high pressure relief valve's
pressure.
4. When the measured pressure is out of the specified
range, remove the lock nut on the high pressure relief
valve and turn the adjusting screw to adjust the pres-
sure.
