Shut off the engine. Loosen the main relief valve (1)
lock nut (2) and turn the adjusting screw (3)
clockwise to increase and counter clockwise to
decrease the pressure.
NOTE:
1/2 turn of the adjusting screw (3) will
change the pressure approximately 500 psi (35 bar).
Hold the adjusting screw (3) from turning and tighten
the lock nut (2).
Repeat Steps 81, 82 and 83 until the pressure gauge
reads 3000 psi (207 bar).
If the pressure can be adjusted to 3000 psi (207 bar),
proceed to Step 84.
If the pressure is more than 3000 psi (207 bar) and
does not change when the adjusting screw (3) is
turned counterclockwise, replace the main relief
valve.
If the pressure is less than 3000 psi (207 bar) and
does not increase when the adjusting screw is turned
clockwise, go to the Pump Pressure Test in this
manual before replacing the relief valve.
STEP 84
If the pump, relief valve or any cylinders are repaired
or replaced, repeat Steps 81, 82 and 83 to set the
main control valve relief pressure at 3000 psi (207
bar).
