Section 7. Component Procedures Lift Pressure Adjustment
Hydraulic Components
Lift Pressure Adjustment The Lift Pressure Relief Valve (REL-1) limits system pressure for lift functions. Perform the following steps to adjust lift system pressure. 1. Lower the carriage and load handler completely. 2. Turn the key switch OFF and disconnect the battery connector. 3. Remove the tractor cover. 4. Model 9600 - Connect a pressure gauge capable of reading 5000 psi (351 kg/cm2) to the Main Lift Pressure Port (TP1) on the main manifold. Refer to Figure 7-92. Model 9700 - Connect a pressure gauge capable of reading 5000 psi (351 kg/cm2) to the Mini Lift Pressure Port (TP2) on the main manifold. Refer to Figure 7-92. Figure 7-92.
Model 9700 - while requesting mini-mast lift, turn the adjusting screw in until the load begins to elevate. Note the pressure required for lift. 9. Adjust REL-1 until lift pressure is 100 to 300 psi (7 to 21 kg/cm2) above the value recorded in step 7. This can be done by elevating the main mast against the mechanical stops (loaded or unloaded). 10. When the pressure is correct, tighten the lock nut on the valve. 11. Check both main and mini mast for correct operation. 12. Lower the load handler completely. Turn the key switch OFF and disconnect the battery connector. 13. Remove the pressure gauge. 14. Install the tractor cover.
