According to manufacturer instructions, the hydraulic oil should be changed
every two years in normal operations. Various environmental 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 unpleasantly.
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 opening.
Dispose of the old oil according to regulations to the intended location (district
offices, environmental protection office or commercial regulatory 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 dura-
tion 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 pressurised
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.
