Operator Controls
NO MOVEMENT OF THE FUNCTION
Check to see that valve spool actuates when control is operated.
If spool shifts, refer to sections on 1) Relief Valve Troubleshooting; 2) Motor, Cylinder or
Winch Troubleshooting according to circuit being checked; 3) Pump Troubleshooting; 4)
Control Valve Troubleshooting.
WITH THE ELECTRICALLY CONTROLLED VALVES on the outriggers, three (3) spools must
be checked.
The diverter valve should be checked by using a test gauge on the test port and activating
the outrigger controls. If pressure (2500 psi) is indicated, the spool is shifting.
Check the outrigger extend-retract and function valves by pushing the. pins in prior to
activating the functions. Check to see if the appropriate pin has been pushed back out as
the functions are activated. If they have, the spools are shifting.
If the spools do not all shift, check the electrical connections. Frequently ground
connection are a problem.
If no electrical power is present at the valve, check the electrical wiring and correct the
fault. Most controls require a minimum of 10 volts.
If power is present, repair or replace the solenoid or valve section which is not shifting.
If the spools shift, see page 5-19, “Outrigger Circuit”.
