SYSTEM DEPRESSURIZATION: Completely lower all attachments to the ground. Turn off the engine and operate all hydraulic control levers through their full range to release residual system pressure.
POWER DISCONNECTION: Always disconnect the negative (-) battery terminal before beginning work to prevent electrical hazards.
CLEAN WORK ENVIRONMENT: Thoroughly clean the area around sensor ports and connections before disassembly to prevent contamination of the hydraulic system.
