Check the hydraulic oil level
Hydraulic Hose Lines
Before working on any hydraulic system or lines
make the system make sure the system or line
pressure has been released or discharged.
Carry out the change of hydraulic oil while it is still
warm in accordance to the lubrication plan and the
lubrication table.
Do not start the motor while the hydraulic oil is drain-
ing under any circumstance.
Immediately replace any damaged seals.
Change the return filter element and the air filter
with each change of hydraulic oil.
Change the hydraulic oil also after each major re-
pair on the hydraulic unit.
Collect the drained-off hydraulic oil and dispose it
in an environment friendly manner.

The function of hydraulic hose lines must be tested at reg-
ular intervals (minimum once a year) by an expert (with a
knowledge of hydraulics).
Hose lines must immediately be replaced in the following
instances:
• Damage to the outer layer to the inner lining (abrasion
marks, cracks, cuts, etc.).
• Brittleness of the outer layer (cracking of hose covering).
• Unnatural deformations of the hose line. This applies to
both a pressureless and pressurized condition (e.g. layer
separation, blister formation, crushed areas, kinks).
• Leaks.
• Damage or deformation of hose fittings (impaired sealing
function).
• Hose slips out of the fitting.
• Corrosion of fitting (degrading of function and strength).
• Improper installation.
• Use beyond the expiry date of max. 6 years.
• Check the oil level through the oil gauge glass.
• If necessary top off the oil level up to the upper area of the
glass.
If hydraulic oil is not visible through the guage
glass, the components, hoses and connections
need to be checked immediately for leaks.
