►

Release the pressure in the hydraulic system.

►

Let the engine cool down.

►

Injury hazard! Fluid escaping under high pressure can damage the
skin and eyes. Removing the filler cap can cause oil to escape.

Can cause severe injuries 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. If oil contacts the eye

flush immediately

with clean water and seek medical treatment.

►

Malfunctioning or leaking threaded fittings, hose connections and
pressure lines must be immediately repaired by a Wacker Neuson
service center (search for hydraulic leaks with a piece of cardboard).

NOTICE

Damage due to wrong hydraulic oil.

►

Use hydraulic oil according to the engine/machine fluids and
lubricants.

►

Have the hydraulic oil only changed by a Wacker Neuson service
center.
