Inspect the hazardous area. No person or ob-
!
ject may stand in the working area of the lift, or
on the lift.
• Open the stainless steel hood.
• Press the double-acting valve (see hydraulic dia-
gram 0.10) on the hydraulic block.
• Pull the operating lever until the lowest position is
reached.
• The entire lowering process must be continuously
observed.
• Afterwards, remove the polymer overlays and
drive the vehicle from the lift.
If required, defective parts must first
be replaced before the lift is put into
operation again. For this, inform cus-
tomer service. Turn the main switch
off and secure against restart. Shut-
down the lift until all defective parts
have been exchanged.
• Only operate the lift if it is in seamless condition
from a safety point of view again.
After exchange of defective parts a "Vent of the
!
hydraulic system" must be done.

Maintenance and care of the system
Before maintenance, do all prepa-
ration work so there is no danger to
life or limb or object damage during
maintenance and repair work.
Value is placed on long lifetimes and safety in the
development and production of Nussbaum prod-
ucts. To guarantee the safety of the operator, prod-
uct reliability, low running costs, keep the warranty
and also the long-lifetime of the product, proper
set up and operation is just as important as regular
maintenance and sufficient care.
Our platforms fulfil or exceed all safety standards of
the countries we supply to. For example, European
regulations require a service by qualified experts
every 12 months of work of the platform. To guar-
antee the largest possible availability and function-
al capacity of the lift system, ensure the list of any
cleaning, care and maintenance work is done.
The lift system is to be serviced at regular intervals
according to the following plan. For intensive oper-
ation and higher degree of contamination shorten
the service interval.
The complete function of the lift system is to be ob-
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 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.
