• The system is fi tted with no-maintenance DU
sliding bearings. Despite this, due to environmen-
tal infl uences 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 biologi-
cally degradable oil). Noises normally occur after
the system has been raised and lowered several
times.
• Check the function of the CE STOP with warning
signal.

turers instructions.

• Exchange the protective and hydraulic hoses.
Excerpt from BGR 237
Specifi cations for the hydraulic hose lines:
• Normal specifi cation:
6 years including 2 years storage time.
• Increased demands e.g. due to increased
usage times, e.g. multi-shift operation, short cy-
cle times and pressure impulses and large ex-
ternal and internal (due to medium) infl uences
which signifi cantly reduce the lifetime of the
hose lines:
2 year operation duration

Cleaning and care of the system

A regular and expert clean helps retain the value
of the system.
Additionally, it can also be a pre-requisiste for the
preservation of guarantee claims for any eventual
corrosion damage.
The best protection for the system is regular
removal of contaminants of any kind.
This includes above all:
• De-icing salt
• Sand, pebbles, earth
• Industrial dust of all types
• Water, also in connection with other environmen-
tal infl uences
• Aggressive deposits of all types
• Permanent humidity due to insuffi cient ventilation
The frequency of system cleaning depends, among
other things on the frequency of use, of system han-
dling, of workshop cleanliness, and the location of
the system.
Furthermore, the degree of contamination de-
pends on the time of year, the weather conditions
and workshop ventilation.
Under adverse circumstances, weekly system
cleaning might be required, however a monthly
cleaning may be suffi cient.
