Safety Precautions
Hydraulic System Hazards
The hydraulic system is under pressure whenever the engine is running and may hold pressure even after the engine is shut off. Cycle all hydraulic controls after the trench boom is resting on the ground. Some components will retain residual or trapped pressure. Use extreme caution when removing any hydraulic component.
During inspection of the hydraulic system:
•Cycle all hydraulic controls to release residual pressure.
•Wait for the hydraulic fluid to cool down before disconnecting any hydraulic lines. Hot hydraulic fluid can cause severe burns.
WARNING
Hydraulic oil under pressure can penetrate body tissue causing serious injury and possible death. When troubleshooting a hydraulic system for leaks, always use cardboard or wood as a detector. DO NOT USE YOUR BARE HANDS. If you are injected with hydraulic oil or any other fluids, immediately seek treatment by a doctor trained in the treatment of penetrating fluid injuries.
•Hydraulic fluid can cause permanent eye injury. Wear safety glasses or a full face shield to provide appropriate eye protection.
•When venting or filling the hydraulic system, loosen the filler cap slowly to allow any pressure in the hydraulic tank to be released and remove the cap gradually.
