3.11 Maintenance work :
- Maintenance work may only be performed by suitably qualified and trained personnel.
- Keep unauthorized persons away from the machine.
- Never carry out maintenance work on a driving machine or with the engine running.
- Park the machine on a firm, even surface.
- Take the key out of the ignition.
- Safeguard the articulated joint with the transport safeguard.
3.11.1 Work on the hydraulic line :
Before performing any work on hydraulic systems, they must be depressurized. Hydraulic oil emerging under
pressure can penetrate the skin and cause serious injury. In case of injury due to oil emerging at high
pressure, immediately consult a doctor as serious infections can result.
When performing setting work at the hydraulic system, do not tread in front of or behind the facings.
Do not adjust the pressure relief valve.
Drain off the hydraulic oil at operating temperature – danger of scalding!
Collect up emerging hydraulic oil and dispose of in an environmentally responsible manner.
Never attempt to start the engine when the hydraulic oil has been drained.
After the completion of all work (with the system still depressurized!), check the seal of all connections and
screw joints.
3.11.2 Exchanging hydraulic hose lines :
Hose lines must never be swapped or exchanged.
Subject hydraulic hose lines to regular visual inspections.
The immediate exchange of hydraulic hose lines is essential in the following cases :
• Damage of the outer ply through to the inlay (e.g. abrasion, cuts)
• Brittleness of the outer ply (crack formation in the hose material).
• Deformation in pressureless or pressurized condition which does not correspond with the original
shape of the hydraulic hose line.
• Deformation on bending, e.g. crushing points, kinks, separation of plies, formation of blisters.
• Leaks.
• Incorrectly executed installation.
• Migration of the hydraulic hose from the fitting.
• Corrosion of the fitting which impairs functional characteristics and strength.
• Damage or deformation of the fitting which impairs functional characteristics, strength or the hose
to hose connection
Only original RAMMAX spare hydraulic hose lines offer the security of using the correct hose type (pressure
stage) in the right situation.
