• Perform maintenance work only after the truck crane has been shut down.
Always ensure that the truck crane is well-protected from unauthorised
operation before beginning maintenance work. Remove the key and put
up warning signs.
If due to exceptional circumstances the truck crane needs be put into oper-
ation for certain types of maintenance work, great care must be taken where
there are
moving parts (superstructure, outriggers, Cardan shafts, slewing
bearing, engines, tiltable crane cab). There is a risk of injury!
• Ensure that all hydraulic components are returned to their initial positions
(e.g. the main boom) or locked (e. g. the outriggers) before starting main-
tenance work.
Escaping hydraulic fluid or compressed air can cause severe injury.
Rememb
er that the hydrauli
c and compressed air systems of the truck crane
are pressurised even when the truck crane is not in operation. Tighten loose
screw connections only when the systems are depressurised. Always
depressurise the hydraulic and compressed air systems before opening
them.
• Do not allow hot fluids to escape in an uncontrolled manner. Risk of scald-
ing!
• Observe the applicable safety regulations when working with flammable
fluids.
• Observe the applicable safety regulations when working with process
materials.
• Switch off all electrical consumers and first disconnect the earthing termi-
nal before removing any electrical batteries.
• Keep in mind the corrosive effect of battery acid.
• Note the fire alarm and fire-fighting facilities on site.
• Return the truck crane to proper working order once maintenance work is
completed. Inform the crane operator accordingly.
