Information regarding the hydraulic system
Burn hazard when performing maintenance on or with the
machine on a hot engine and hydraulic system.
Can result in severe injury or death.
► Wait at least 10 minutes after stopping the engine.
► Wear protective equipment.
Injury hazard! Fluid escaping under high pressure can
damage the skin and eyes. Removing the filler cap can
cause oil to escape.
Can result in severe injury or death.
► Do not operate the machine with leaking or damaged
hydraulic system components.
► Open the breather filter carefully to slowly release the
pressure inside the tank.
► Wear protective equipment.
► Wear safety glasses to protect the eyes. If oil contacts the eye
flush immediately 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 biodegradable 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.
