9. Maintenance and repair
9.1 Qualification of maintenance and
repair staff
Maintenance and repair work may only be carried
out by an authorized
maintenance contractor
(
Chapter 2.6).
9.2 Maintenance and repair safety reg-
ulations
Only qualified electricians may work on electrical
equipment on the machine.
Only qualified staff with specialist knowledge and
experience with hydraulics or pneumatics may
work on hydraulic or pneumatic equipment.
Ensure that you follow the instructions listed in
2, Safety.
When working on the hydraulics or on pneumatic
equipment, ensure that you follow the safety
regulations listed in the supplied power unit oper-
ating instructions annexed to this manual.
Only perform maintenance on unloaded lifts and
rolling jacks.
Main lifts and rolling jacks must be lowered com-
pletely or latched into the lock positions (locking
latches).
Prevent environmental hazards:
●
Mineral-oil-based hydraulic oil is combustible
and a water pollutant. It must only be used in
conjunction with the relevant safety data sheet
and if all specified measures contained therein
are implemented.
●
Provide suitable oil drain pans and oil absor-
bents.
●
Ensure that no hydraulic oils, lubricants or
cleaning materials contaminate the soil or leak
into the drainage system.
●
Comply with local regulations for handling wa-
ter pollutants, for example for absorbing leaking
fluids or fluids from oil separators.
Avoid contact with or inhalation of toxic sub-
stances such as hydraulic fluid.
Wear protective clothing, for example protective
goggles, protective gloves etc.
Before all maintenance and repair work:
●
secure the post lift zone with a red-white chain
and warning notices.
●
turn the main switch to OFF ("OFF
“ Position).
●
disconnect the air supply (manometer on the
compressor unit to 0 bar).
●
inform all persons in the area about the
maintenance and repair work.
Only use original spare parts from the manufac-
turer.
Tighten all fittings after maintenance work ac-
cording to the specified torque figures.
The default setting for safety valves must be a
maximum of 10 % or a minimum of 20 bar above
the operating pressure of the machine. The safety
valve settings may not be adjusted.
Remove all used materials, tools and other ob-
jects from the danger zone after cleaning,
maintenance, and repair work.
Dispose of hydraulic oils, lubricants, cleaning
materials, and replaced parts in accordance with
environmental regulations.
DANGER
Inadequate maintenance and repair
work may cause serious injury and
also lead to damage to property. A
safety risk as well as a risk of fatal
injury exists during operation.
Follow the maintenance and repair instructions
below carefully.
Regularly clean the post lift (
Chapter 8).
Comply with maintenance intervals (
Chapter
9.3). This will keep the post lift in perfect work-
ing condition and guarantee safe operation.
Maintenance and repair work must be docu-
mented (
annex, maintenance schedule,
regular maintenance reports, and repair re-
ports).
