7.1
System maintenance plan
Before beginning service, disconnect
from power. The system is to be se-
cured against unintentional lowering
and unauthorised access.
7.1.1 As required or visible damage
Check the polymer overlays and replace if required.
7.1.2 Maintenance 1 x per year
• 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.
• Lubricate all lubrication nipples with an acid-free
multi-purpose grease. Do not over-lubricate.
• 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 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.
Optional CE stop switch and signalling unit
Push button, main switch
Electrical cable
During assembly and maintenance always check
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.
• Check the foot bumper for condition and func-
tion. Exchange if damaged
