6.1.3 Maintenance every 2 years

• 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 (18), the hydraulic oil must be between the
upper and lower marking on the oil dipstick, or
approx. 2 cm below the oil filling opening.
Dispose of the old oil according to regulations
to the intended location (district offices, environ-
mental protection office or commercial regula-
tory office has the obligation to disclose about
disposal points).

6.1.4 Maintenance every 6 years

• Exchange the protective and hydraulic hoses.
Excerpt from BGR 237
Specifications for the hydraulic hose lines:
• Normal specification:
6 years including 2 years storage time.
• Increased demands e.g. due to increased usa-
ge times, e.g. multi-shift operation, short cycle
times and pressure impulses and large external
and internal (due to medium) influences which
significantly 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 remo-
val 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 environ-
mental influences
• Aggressive deposits of all types
• Permanent humidity due to insufficient ventilati-
on
• If fluid is sitting in the lift grooves
The longer road dust, salt, and other aggressive
deposits remain caked onto the lift, the more da-
mage occurs.
The frequency of system cleaning depends,
among other things on the frequency of use, of
system handling, 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 sufficient.
Do not use and aggressive and abrasive materi-
als for cleaning, rather use mild cleaners, e.g. a
commercially available detergent and luke warm
water.
• For cleaning, do not use high pressure washers
(e.g. steam cleaners)
• carefully remove all contamination with a
sponge, or if required with a brush.
• Make sure that there is no residue of the cleaner
on the system.
• Dry the system with a cloth and spray it with a
spray wax or oil.
• Moving parts (bolts, bearing zones) are to be lu-
bricated or oiled according to instructions.
• When cleaning the workshop floor ensure that
no aggressive cleaning materials come into
contact with lift surfaces. Permanent contact
with any kind of liquid is prohibited. This is also
true for the fastening anchors.
