• Check the powder coating and improve if re-
quired.
Damage by external influences is to be treated
immediately after detection. If these points are
not treated, infiltration of deposits of all kinds can
cause wide-ranging and permanent damage.
These points are to be lightly sanded (120 grit),
cleaned and degreased. Afterwards, rework with
a suitable touch up paint (note the RAL No.).
• Check galvanised surfaces and touch up as
needed.
White rust is fostered by permanent humidity,
poor ventilation.
Rust is brought out by mechanical damage,
wear, aggressive deposits (de-icing salt, leaking
operating fluids) cleaning that is not done or in-
complete.
The affected areas can be treated by using a
sanding cloth (A 280 grit). If required, these are-
as are to be post-treated with a suitable, resistant
material (paint etc.).
• Check the condition and function of the driving
ramp.
• Check the condition of the cement floor.
• Check the torque of the fastening anchor. Also
see the assembly protocol.
• The condition and function of the load suspension
means are to be checked.
• Check the torque of the fastening screws.
Torque (Nm) for shaft screws.

• Check electrical components for function. Re-
place any damaged components.

the condition of electrical lines. All cables and
lines must be secured so they cannot be crushed,
kinked or contact any moving assembly.
• Check hydraulic oil.
The oil is used if it has a milky colour or if the hy-
draulic oil smells unpleasantly.
• Check the hydraulic lines and screws for leaks.
• Hose lines are to be replaced:
- For damage to the outer coating up to the in-
sert (chafe marks, cuts, cracks).
- For brittleness of the outer coating (crack for-
mation), deformation of the natural shape in
the depressurised and in pressurised states.
- If leaking.
- For damage or deformation of the mounting fix-
ture.
- If the mounting fixture has meandered.
- If 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 inter-
val, no situation may occur which could result in
injury of employees or other personnel.
• Check the condition and function of all available
safety devices.
7.1.3 Maintenance every 2 years
According to manufacturer details, 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 hy-
draulic 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 hydrau-
lic oil smells unpleasantly.
To change oil, lower the lift is to its lowest position
then suction the oil out of the oil container and re-
place the contents.
The manufacturer recommends
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 up-
per and lower marking on the oil dipstick, or ap-
prox. 2 cm below the oil filling opening.
Dispose of the old oil according to regulations to
the intended location (district offices, environmen-
tal protection office or commercial regulatory of-
fice has the obligation to disclose about disposal
points).

7.1.4 Maintenance every 6 years

• Exchange the protective and hydraulic hoses.
