According to manufacturer instructions, the hydraulic oil should be
changed every two years in normal operations. Various environmen-
tal influences e.g. location, temperature swings, intensive operation
etc, can have an influence on the quality of the hydraulic oil. For this
reason, the oil must be checked during annual safety inspections and
maintenance.
The oil is used if it has a milky colour or if the hydraulic oil smells unpleas-
antly.
To change oil, lower the lift is to its lowest position then suction the oil
out of the oil container and replace the contents.
The manufacturer recommends a high-quality clean hydraulic oil. The
required oil volume and type is to be taken from the technical data.
After filling, the hydraulic oil must be between the upper and lower
marking on the oil dipstick, or approx. 2,5 cm below the oil filling open-
ing.
Dispose of the old oil according to regulations to the intended location
(district offices, environmental protection office or commercial regula-
tory office has the obligation to disclose about disposal points).
Hydraulic hose lines
Storage and duration of use
Excerpt from DIN20066:2002-10
• For permitted loading, hoses undergo a natural change. This limits
the duration of use.
• Improper storage, mechanical damage and unpermitted loads are
the most frequent cause of breakdowns.
• The duration of use of a hose line including any storage time should
not exceed six years.
Hose lines are to be replaced if/when,
• Damage to the outer coating up to the insert (chafe marks, cuts,
cracks).
• The outer coating becomes brittle (crack formation).
• Deformation from the natural shape in the depressurised and pres-
surised conditions.
• Leakage.
• Damage or deformation of the mounting fixture.
• Meandering of the mounting fixture.
• The lifetime has been exceeded.
Repair of the hose line using the implemented hose / mounting fixture
is not permitted.
Extending the replacement intervals given in the guideline is possible
if the inspection for safe-work condition is done in adjusted, shortened
time frames, if required and by competent personnel.
If there is an extension of the replacement interval, no situation may
occur which could result in injury of employees or other personnel.
