8. Maintenance and Service
8.1. Service
No welding/drilling work on the crane
DANGER
• Do not do any welding work on the crane.
Welding work on the crane may only be
carried out by a Hiab authorised service
workshop, or in close consultation with
Hiab.
• Do not drill into the crane yourself. Drilling
work on the crane may only be carried out
by a Hiab authorised service workshop, or
in close consultation with Hiab.
• Never try to reinstall the crane. Only a
Hiab Installer may reinstall the crane.
Leakages
DANGER
• STAY AWAY from oil leaks in the hydraulic system! Oil in the hydraulic system is
under high pressure, can spill, be very hot and cause you injury.
• Do not replace any hydraulic hoses or lines yourself.
You can disconnect a hydraulic line or a hose only for specific operator’s tasks (for example,
disconnecting the JIB or other accessories).
1. Make sure that the cylinders are not at the end of stroke and minimise as much as possible the
forces acting on them.
2. Switch off the system.
3. Disengage the PTO.
4. Make sure that you wear the correct personal protective equipment.
5. Move all levers in both directions to the end of the stroke to release all the pressure in the line.
6. Slowly loosen all connectors.
7. If they do not come out easily, you have remaining pressure in the line. Stop and do step 5
again.
Deal with an oil leak as follows:
1. Rest the crane on the floor or on the truck platform.
2. Switch off the control system.
3. Disengage the PTO.
