• Lubricate all lubrication nipples with a multi-pur-
pose grease.
• Check set down catches for ease of latching and
clean and lightly lubricate friction surfaces.
• condition of the load cable: if wire breaks can
be seen on a a wire cable, the entire cable set
must be exchanged.
• check all available safety devices for function.
e.g. catches, switch, CE stop, warning signal,
main switch, return and rollover safeties, etc.
• check hydraulic oil for wear. The oil is used if it
has a milky colour or if the hydraulic oil smells un-
pleasant.
• All weld seams must have a visual inspection.
Stop the system and contact the manufacturer if
there are cracks or breaks in weld seams.
• check galvanized surfaces and touch up as
needed. White rust is fostered by permanent hu-
midity, poor ventilation.
Rust is brought out by mechanical damage, wear,
aggressive deposits (de-icing salt, leaking opera-
ting fluids) cleaning that is not done or incomplete.
The affected areas can be treated by using a
sanding cloth (A 280 grit). If required, the parts
are to be treated with a suitable, resistant mate-
rial (paint etc).
• check the filling level of the hydraulic oil.
• check the protective hose and hydraulic hoses:
Check the condition of the protective hose
around the hydraulic lines. These should be ex-
changed if there is damage. When doing this,
hydraulic lines are absolutely to be checked for
possible crushing points. Lines which have been
crushed must be exchanged. Otherwise pressu-
rized hoses must be exchange as required, ho-
wever at latest after 6 years.
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 depressurized and in pressurized states.

• if leaking
• for damage or deformation of the mounting
fixture
• 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 fra-
mes, if required and by competent personnel.
If ther is an extension of the replacement inter-
val, no situation may occur which could result in
injury of employees or other personnel.
• The condition and function of the wheel jacks
are to be checked.
• check the torque of the fastening anchor. See
the data sheet for the relevant anchor manufac-
turer.
• check the torque of the fastening screws. Also
see the assembly protocol.
