Place the hydraulic breaker on timber support blocks.
The breaker box service opening must be facing up-
wards.
2.
Depressurise the hydraulic system before discon-
necting a hydraulic hose (see chapter Depressuris-
ing the hydraulic system).
3.
Remove the cover of the service opening.
4.
Connect the pressure gauge to the HP-accumulator
via the pressure line »P«.
5.
Close the tank line »T«.
You need an assistant to monitor the pressure
gauge.
WARNING Injury by impacts
A sudden movement of the carrier may cause your
assistant to be hit and injured by the boom or the hy-
draulic attachment.
u Only move the boom very slowly and in a con-
trolled manner while an assistant is within the
danger zone.
u Always keep sight of your assistant.
6.
Switch on the hydraulic breaker at the lowest possi-
ble engine rpm and mode level.

sistant indicates that the operating pressure (180bar
(2610psi)) is reached.
8.
Open the tank line »T« a little and slowly release
pressure.
9.
Watch the pressure gauge during the release proce-
dure. As soon as the gas pressure in the HP-accu-
mulator is reached, the indicator stops shortly and
then drops sharply to zero.

50bar (725psi). Refilling must be performed by an
