Step 6: Relief valve adjustment
The control valve is equipped with a relief valve to release the excess pressure
inside the power steering hydraulic system.
Note!
Do not unscrew the relief valve needlessly to ensure maximum
efficiency of the power steering.
Note!
Adjust the control valve only when all the previous steps have been
performed.
Note!
Adjust the release point of the tractor hydraulic lever prior to adjust the
control valve.
Note!
The tractor hydraulic lever will return to neutral position when the relief
valve is set too high.
● Set the tractor oil flow to minimum;
● Slowly unscrew the relief valve (1)
until the lever of the tractor stops
returning to neutral position
automatically.
