4. Check all hydraulic hoses, lines, and ttings.
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 uids, immediately seek treatment by a doctor
trained in the treatment of penetrating uid injuries.
• Visually inspect all of the hydraulic hoses, lines, and fittings for signs of damage, wear or
leaking.
• If any signs of damage are visible, do not operate the machine until repairs have been made.
• Some examples of common hydraulic hose damage are shown in Figure 3–4.
