Hydraulic System Checks And Setup; Setting The Valve Spool Stops - Raven SmarTrax Installation Manual

2. In some cases, an extension hose may need to be used to reach the Raven steering control
valve. If an extension hose is made, be sure that the extension hose is the same inside
diameter as the original hose. If the hose inside diameter is too large or too small, the vehicles
hydraulic system will not perform as expected. (For more details, see the installers worksheet)
LS-Steer Hose
1. Connect the provided pressure switch with tee fitting directly to the port labeled LS-Steer.
2. Depending on valve orientation, the pressure switch may need to be moved to the adjacent
branch of the tee fitting.
3. Once the pressure switch is installed, run a new hose from the open branch on the tee to the
Load Sense port on the tractors steering orbital. This port should be open as the original hose
was removed and run to the LS-PV port in the previous step.
4. When making the hose for this connection, it is important to use hose with the same inside
diameter as the original load sense hose. Failure to use identical size hose will effect the
vehicles hydraulic system. (For more details, see the installers worksheet)

HYDRAULIC SYSTEM CHECKS AND SETUP

Once all of the hoses have been hooked up, go back and verify that all hose fittings and
connections are tight, and that the hoses are attached to their appropriate ports.
Once the hydraulic system has been plumbed, it is important to start the tractor and verify that
there are no leaks and that the hoses have been hooked up correctly.
WARNING!
machine stand clear, in the case that a hose has not been completely tightened.
Once the machine is started and running, a complete inspection of the hoses, fittings and
valves should be done to verify that the system is leak free.
In some instances, it may be found that air has gotten into the hydraulic system. If this
happens, it is important to remove the air from the system by turning the steering wheel from
lock to lock several times.
Once the valve is tested, attach the supplied warning label on or near the valve.

SETTING THE VALVE SPOOL STOPS

The steering control valve will not come from the factory preset. Flow rates to the cylinders
must be set so that the wheels turn left and right at the same rate.
It is recommended that lock to lock turning time achieved by the steering control valve should
be approximately 15 seconds in both directions. To verify this setting, the steering control
valve must be pulsed using the SmarTrax controller. In the solenoid control config menu, use
the LesR screen to pulse the valve.
To pulse the steering control valve, the steering wheel should be turned all the way to the left,
and then pulsed to the right.
Upon initial system start up, it is important that any person near the
