Hydraulic system

7.1 Safety notes Observe the safety notes before starting work on hydraulic system.

Danger Work on hydraulic systems may only be carried out by trained personnel with special knowledge and experience on hydraulics.

Wear personal safety equipment (e.g. safety helmet, ear protection, protective gloves, safety boots).

Warning of high oil pressure!

The hydraulic system is subject to high pressure. Serious injuries can be caused by escaping hydraulic oil when loosening a hydraulic connection or when a leak occurs.

Only carry out work on a de-pressurised hydraulic system!

De-pressurise hydraulic system before starting retrofitting work (see Section 7.4).

The pilot control is equipped with a pressure accumulator, which remains under high pressure even after the engine is shut down.

Therefore, de-pressurise the pressure accumulator.

Danger of injury!

If leaks are present hydraulic oil will leak out under high pressure.

Hydraulic oil will leak out under high pressure, penetrate the skin and cause severe damage to health.

Danger of infection. In the case of injury contact a doctor immediately!

Hydraulic system - General information

7.2

General information

7.2.1 Hydraulic cylinder Pressure cylinders are subject to slight leakage. Remove excess leakage residue with a cloth. Dispose of oil-soaked cloth as hazardous waste.

The sliding surfaces of the piston rods are chrome-plated. Heavier leakage indicates damaged sliding surfaces or defective seals.

Cleaning hydraulic cylinders:

Do not use sharp edged tools, caustic fluids or abrasives.

Wash down piston rods regularly with steam cleaner. Do not direct the jet straight at the sealing elements.

Apply preservative to extended piston rods after cleaning. This protects the surface from the effects of environment and weather.

7.2.2 Screw connections Check hydraulic screw connections and couplings regularly for leaktightness. Seal points of leakage and remove oil residue.

Leaking hydraulic oil endangers the environment and presents a hazard due to danger of slipping.

Always seal opened screw connections immediately at both sides with plugs.

7-2

835 / 06.2003

Hydraulic system - Hydraulic lines

7.3 Storage and duration of use

Hydraulic lines

Even when used correctly at permissible loads, hoses and hose lines are subject to natural wear and tear. Their service life is therefore limited.

The operator is responsible for ensuring that hose lines are replaced at suitable intervals, even when there are no obvious defects to be seen in the hose line.

Hose lines must be replaced at least every six years, including a maximum of two years storage time, where applicable.

Check

Hose lines should be inspected by a specialist technician at least once a year to ensure that they are functioning correctly.

Remedy any defects discovered immediately.

Defects

Replace hose lines in the following cases (see also DIN 20 066):

Outer layer damaged as far as reinforcement (e.g. abrasion points, cuts, cracks);

Outer layer brittle (cracks appearing in hose material); Deformation, which does not conform to the natural shape of the hose or hose line, both when under and not under pressure, or when bent (e.g. layer separation, bubbles forming);

Leaks; Hose fittings damaged or deformed (sealing function affected); Hose has separated from fittings; Corrosion of fittings which reduces function and strength; Installation requirements ignored; Storage times and/or service life exceeded.
