Pull out the base and platform e-stops.
3.
From the base controls, use the e-pump switch
in combinating with the telescope retract switch
to activate the pressure on the gauge. Check
the reading while still retracting.

The pressure should be 228 bar (3300 psi).
Follow the next steps for adjusting the pressure
if needed.
5.
Locate relief valve
RV6
on the e-pump.
6.
Loosen the lock nut on the relief valve.
7.
Turn the adjusting stem clockwise to increase
the pressure and counterclockwise to decrease
the pressure until 228 bar (3300 psi) is observed
on the gauge.
8.
Tighten the lock nut.
5.5-6 Turret Rotate Relief Valve
Adjustment (RV3)
