Traction Locks Up / Warning Alarm Sounds

Diagnosis & fix steps

LOGIC: Hydrostatic Charge Pressure Below Critical Shutdown Level. ACTION: Install a 0–600 PSI mechanical gauge on the hydrostatic charge test port (must read >320 PSI at idle). Inspect hydraulic oil charge filter for collapse; test charge relief valve on tandem pump.

Red Seal field insights

Cold-Start Cavitation: Running heavy hydraulic loads with viscous, sub-zero ISO 46 oil starves the hydrostatic charge pump, tripping low pressure switches and locking the spring-applied brakes.
