Slow lifting under load
Lift or tilt function cuts out
Loss of traction power
Function inhibited by SAS/OPSS
Measure main hydraulic pressure at the test port against the manufacturer limit.
Measure pump flow under load and compare it with cylinder cycle time.
Measure battery/supply voltage drop separately under lift and traction load.
Separate pump, relief, valve and cylinder internal leakage using pressure, flow and cycle-time together.
Separate a safety-interlock inhibit from a genuine hydraulic or traction fault.
Record controller event codes, SAS/OPSS interlock state and related sensor inputs during the same event.
At rated load, lift/lower, tilt and traction functions must operate continuously and the event must not return.
Power system, traction/engine controller, hydraulic controller and SAS/OPSS safety inputs are evaluated together.
