ADJUSTMENTS & PROCEDURES
NAUTILUS MAIN BRUSH AND IMPELLER PRESSURE RELIEF ADJUSTMENTS
These adjustments are necessary if the hydraulic manifolds are supplied with the relief valves set at zero or incorrectly set.
MAIN BRUSH PRESSURE RELIEF ADJUSTMENT:
•Install an appropriate pressure gauge at the gauge port on the main hydraulic manifold. The gauge port (GA) is located on the left side of the
manifold when viewed from the front of the machine.
•Disconnect the electrical connection to the main brush solenoid SV3 located in the lower left manifold port 3.2 (after the first 5 prototypes the 3.2
port location will be embossed as 10). This will block the flow out of the manifold and force the fluid flow to go over the relief valve RV2.
•Loosen the lock nut and unscrew the pressure adjustment screw on the pressure relief valve RV2. This will allow all of the fluid flow to pass at low
pressure through the relief valve.
•Start the machine and switch the engine throttle switch to operating (high) speed.
•Turn on the brushes.
•Turn the pressure relief adjustment screw in (clockwise) while monitoring the hydraulic pressure on the pressure gauge.
When the gauge reads 2500 psi (it will vary a little, and that is OK) tighten the adjustment screw lock nut and turn off the engine.
NOTE: Perform the adjustment as quickly as possible. During this set up do not run the machine for an extended period of time after the pressure
relief is set as the hydraulic oil will generate excessive heat when going through the pressure relief valve.
•Reconnect the electrical connection to the SV3 solenoid.
This completes the main brush pressure relief adjustment.
