WARNING: Pressurized fluid can penetrate body tissue and result in serious injury or death.
Leaks can be invisible. Keep away from any suspected leak. Relieve pressure in the hydraulic
system before searching for leaks, disconnecting hoses, or performing any other work on the
system. If you must pressurize the system to find a suspected leak, use an object such as a
piece of wood or cardboard rather than your hands. When loosening a fitting where some
residual pressure may exist, slowly loosen the fitting until oil begins to leak. Wait for leaking to
stop before disconnecting the fitting. Fluid injected under the skin must be removed
immediately by a surgeon familiar with this type of injury.
WARNING: Fuel and fumes can explode and burn.
Shut off engine before refueling. No flame. No smoking.
