Danger from residual pressure in hydraulic lines
Residual pressure in the hydraulic system can cause
severe or fatal injuries!
- Proceed as follows before working on the hydraulic
system:
1. Place the machine on a level surface, secure it
against accidentally rolling away and activate the
parking brake if necessary.
- Depressurise the hydraulic system for maintenance:
2. Open hopper.
3. Move levelling cylinder to lower limit position.
4. Retract screed.
5. Lower the screed to the floating position.
6. Set crowning to 0°.
7. Move front hopper cylinder to lower limit position.
8. Retract the auger lifting cylinder.
9. Centre the platform in the centre position.
- Stop the engine and remove the ignition key before any
maintenance work.
- Secure the machine against being switched on,
disconnect the battery from the vehicle electrical system.
- Let the hydraulic oil cool down.
- Allow a waiting period to relieve residual pressures.
- Depressurise the diaphragm accumulator by waiting at
least 20 minutes after stopping the engine.
- Do not carry out any maintenance work on the drive
system until the system pressure has been relieved.
Make sure that the oil pressure of the diaphragm
accumulator is completely released with a measurement
at the measuring connections contained in the
switching circuit.
- Stop the engine and remove the ignition key before any
maintenance work.
- Secure the vehicle to prevent it being switched on again.
- Let the hydraulic oil cool down.
A
After depressurising, begin slowly and carefully
when opening the threaded connections in the hy-
draulic lines.
Continue to loosen the threaded connections with
caution in order to notice possible dangers resulting
from any still remaining pressure in the hydraulic flu-
id (here it may help to knock gently on the threaded
connection) so that precautions can be taken.
Do not continue loosening the threaded connection
if there is still any remaining pressure in the system.
Depressurise the system again and check once
more that this has been effective.
