Important information on the hydraulic system
Burn hazard during maintenance on a hot engine and
hydraulic system!
Can cause serious injury or death.
• Wait at least 10 minutes after stopping the engine.
• Wear protective equipment.
Fluid ejection hazard! Removing the filler plug can cause oil
to escape.
Can cause serious injury or death.
• Do not operate the machine with leaking or damaged hydraulic system
components.
• Wear protective equipment.
• Wear safety glasses to protect the eyes. If oil contacts the eye flush imme-
diately with clean water and seek medical treatment.
In order to avoid damage to the hydraulic system:
• Use hydraulic oil and grade according to fluids and lubricants table.
• Always add hydraulic oil using the filling screen.
• Check the hydraulic oil level once a day.
• If the hydraulic oil in the sight glass is cloudy, this indicates that water or air has
penetrated the hydraulic system. Contact a Wacker Neuson service center.
• If the hydraulic system is filled with biodegradable oil, then use only biode-
gradable oil of the same type for filling up – observe the sticker on the hydraulic
oil reservoir.
• Contact a Wacker Neuson service center if the filter of the hydraulic system is dirty.
