System Maintenance Plan; As Required Or Visible Damage; Maintenance 1 X Per Year - ATT Nussbaum SPRINTER MOBIL 2500 Manuel D'exploitation

served during daily use. Customer service must be
informed of any malfunctions or leaks.
To simplify maintenance work, follow instructions on
the maintenance sticker that is found somewhere
on the unit, depending on the lift design.
7.1

System maintenance plan

Before beginning service, disconnect
from power. The system is to be se-
cured against unintentional lowering
and unauthorized access.

As required or visible damage

7.2.1 Maintenance 1 x per year

• Check condition of the model plate, load capac-
ity and sticker. Exchange them if damaged or il-
legible.
• Check condition of the Model plate, load capac-
ity and sticker. Exchange them If damaged or il-
legible.
• Free the piston rod of the lifting cylinder of sand
and dirt.
• Check the wiper for damage.
• Moving parts such as joint bolts and DU bearings,
sliding pieces, sliding surfaces and rollers are to
be cleaned and checked for wear, exchange if
required.
• Moving parts such as joint bolts, sliding pieces and
sliding surfaces are to be cleaned and checked
for wear and lightly greased. Do not over-lubricate.
• Check the polymer overlays and replace if re-
quired.
• Check all available safety devices for function.
• Check the state and function of the mobile set.
• Check ease of motion of the tow bar (8), guide
roller (6) and wheel axles (9).
• According to manufacturer instructions, the hy-
draulic oil should be changed every two years in
normal operations. Various environmental influ-
ences e.g. location, temperature swings, inten-
sive operation etc., can have an influence on the
quality of the hydraulic oil. For this reason, the oil
must be checked during annual safety inspec-
tions and maintenance.
The oil is used if it has a milky colour or if the hy-
draulic 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 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, environ-
OPI_SPRINTER MOBIL 2500-3000_V3.1_DE-EN-FR-ES-IT
mental protection office or commercial regulato-
ry office has the obligation to disclose about dis-
posal points).
• 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 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 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
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, 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 influences, 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 insert
(chafe marks, cuts, cracks)
- for brittleness of the outer coating (crack forma-
tion), deformation of the natural shape in the
depressurized and in pressurized 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 ther is an extension of the replacement interval,
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 suspension
