Maintenance
5.8 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 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 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 your 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.
Contaminated hydraulic oil, lack of oil or wrong hydraulic oil –
Danger of severe damage to the hydraulic system!
☞ Take care to avoid contamination when working!
☞ Always fill in hydraulic oil using the filling screen!
☞ Only use authorised oils of the same type
– see chapter 5.14 Fluids and lubricants on page 5-34
☞ Always fill up hydraulic oil before the level gets too low
– see Filling up hydraulic oil on page 5-19
☞ If the hydraulic system is filled with biodegradable oil, then only use
biodegradable 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 contaminated with
metal chippings. Otherwise, follow-on damage can result!
Collect drained hydraulic oil and biodegradable oil in a suitable container!
Dispose 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.
