MODEL 200 UC HYDRAULICS
HYDRAULIC PRESSURE ADJUSTMENT
NO PRESSURE CHECK KIT
MAINTAIN FEEDWHEEL HYDRAULIC PRESSURE AT SPECIFIED PSI (bar).
1. Put the control bar in the o position.
2. Disconnect the autofeed block from the control
valve and plug the port on the autofeed block.
If your machine has only one feedwheel,
disconnect the hydraulic hose going from the
control valve to the feedwheel motor at the
feedwheel control valve end and plug the end
of the hose.
3. Leave all other hydraulic hoses connected.
4. Install pressure gauge in port on the control
valve from which the autofeed block or hose
was disconnected.
5. Start engine with the control bar in the o
position.
6. Adjust engine to full throttle.
7. Engage control bar to the normal operating
position to activate a reading on the pressure
gauge.
With the engine shut down, make sure the hydraulic oil is clean and the tank is 7/8 full. Start the engine
to allow the hydraulic oil to warm up. Before checking or adjusting the hydraulic pressure settings, make
sure the engine is shut o and the ignition key is in your possession. Ensure the pressure gauge is installed
correctly to check the relief valve pressure.
8. Pressure gauge should read maximum specied
PSI (bar).
ONLY ENGAGE CONTROL BAR FOR 4-5
SECONDS TO SET PRESSURE OR YOU
MAY DAMAGE HYDRAULICS.
9. Locate relief next to autofeed solenoid, loosen
jam nut, use an allen wrench to readjust relief
pressure setting if needed, and then retighten
jam nut.
10. Reassemble autofeed block or hose to control
valve.
11. Check for hydraulic leaks.
12. Relief valve pressure should be checked and/or
readjusted every month for best performance.
