Maintenance Every 2 Years - Nussbaum SPRINTER MOBIL 2500 Betriebsanleitung Und Prüfbuch

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 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 luids) 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 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. During this, check
hydraulic lines for any crushing points (from third
party inluences, e.g rolling over it with a load).
Any affected lines must be exchanged. Other-
wise pressurized hoses must be exchange as re-
quired, however 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
ixture
• if the mounting ixture has meandered
• if the lifetime has been exceeded
Repair of the hose line using the implemented
hose / mounting ixture 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 per-
sonnel.
If ther is an extension of the replacement inter-
val, no situation may occur which could result in
injury of employees or other personnel.
• For systems with aluminium panelling, these must
be removed to clean the drive in rails of dirt.
• Check the torque of the fastening anchor.
• The condition and function of the load suspensi-
on means are to be checked.
• Check the torque of the fastening screws.

• The system is itted with no-maintenance DU
sliding bearings. Despite this, due to environmen-
tal inluences of various kinds (e.g. humidity, dust,
dirt) bearing zones may become noisy.
In this case, spray the affected areas with an
acid and resin free oil spray (no adhesive oil or
biologically degradable oil). Noises normally
occur after the system has been raised and lo-
wered several times.
• Check the function of the CE STOP with warning
signal.

acturers instructions.
