Maintenance
5.11 Hydraulic system
Specific safety instructions
• Release the pressure in all lines carrying hydraulic oil prior to any maintenance and
repair work. To do this:
• Lower the boom or the attachment to the ground.
• Move all control levers of the hydraulic control valves several times.
• Raise the control lever base.
• Hydraulic oil escaping under high pressure can penetrate the skin and cause serious
injuries. Therefore always consult a doctor immediately, even in the case of minor
wounds – 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 can cause damage to the hydraulic pump.
• Oil or fuel flowing out of high pressure lines can 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 a Wacker Neuson dealer immediately.
• Have a line replaced if one of the following problems 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.
Caution!
Dirty hydraulic oil, lack of oil or wrong hydraulic oil –
Danger of severe damage to the hydraulic system.
☞
Take care to avoid dirt when working.
☞
Always add hydraulic oil using the filling screen.
☞
Only use authorized oils of the same type
☞
Always add hydraulic oil before the level gets too low
☞
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 tank.
☞
Contact customer service if the hydraulic system filter is dirty and contains
metal chippings. Otherwise, follow-on damage can result.
Environment!

pose of drained oil and used filters by an ecologically safe method. Always
contact the relevant authorities or commercial establishments in charge of oil
disposal before disposing of biodegradable oil.
