Maintenance
5.8 Hydraulic system
Specific safety instructions
WARNING
Pressurized hydraulic oil hazard. Hydraulic oil escaping under high pressure
can catch fire, damage property, penetrate the skin and cause severe burns
and injuries.
☞ Do not operate the machine with leaking or damaged hydraulic system
components.
☞ Use a piece of cardboard to diagnose the source of hydraulic leaks.
☞ Hydraulic oil can be hot and may cause serious burns if contact is made
with skin. If contact occurs with hot oil, seek immediate medical attention
and treatment for the burn.
☞ Wear safety glasses to avoid eye contact. If oil contacts the eye flush
immediately with clean water and seek emergency medical treatment.
☞ Seek immediate medical attention if oil penetrates the skin. Oil may cause
serious infections.
• Release the pressure in all lines carrying hydraulic oil prior to any maintenance and
repair work. To do this:
• Lower all hydraulically controlled attachments
• Move all control levers of the hydraulic control valves several times
• Hydraulic oil escaping under high pressure can penetrate the skin and cause serious
injuries. Always consult a doctor immediately even if the wound seems insignificant—
otherwise serious infections could set in!
• If the hydraulic oil in the sight glass is cloudy, this indicates that water or air has
penetrated the hydraulic system. This may cause damage to the hydraulic pump!
• Oil flowing out of high pressure lines may cause fire or malfunctions, and severe
injuries or damage to property. Interrupt work immediately if slack nuts or damaged
hoses and lines are detected.
☞ Contact your Wacker Neuson dealer immediately
• Replace the hose or line if one of the problems mentioned below is detected.
☞ Damaged or leaky hydraulic seals.
☞ Worn or torn shells or uncovered reinforcement branches.
☞ Expanded shells in several positions.
☞ Entangled or crushed movable parts.
☞ Foreign bodies jammed or stuck in protective layers.
