Hydraulic oil under pressure can penetrate body tissue causing serious injury and
possible death. When troubleshooting a hydraulic system for leaks, always use cardboard

hydraulic oil or any other fluids, immediately seek treatment by a doctor trained in the
treatment of penetrating fluid injuries.
