Hydraulic installation,
precautions
WARNING Hydraulic pressure too high
If the hydraulic pressure is too high, the parts of
the hydraulic attachment will be exposed to
excessively high loads. Parts can break loose or
burst causing serious injuries.
►
Lay the drain line of the pressure relief valve
directly in the tank to ensure the safe
functioning of the pressure relief valve!
►
The pressure relief valve must be set at the
maximum static pressure.
►
The pressure relief valve setting must be
checked to ensure that the maximum static
pressure (see chapter Technical specifications)
of the hydraulic installation is not exceeded at
any time. Attach a lead seal to the pressure
relief valve.
►
Prior to their first use, the safety facilities on the
hydraulic installation must be checked by a
professional/authorised monitoring body for
their quality (CE mark etc.), suitability and
proper functioning.
►
If any significant changes are made to the
hydraulic installation, a new acceptance
inspection is to be carried out in accordance
with the relevant national safety provisions.
WARNING Hot hydraulic oil squirting out
The hydraulic system is under high pressure.
Hydraulic lines may spring a leak or burst.
Hydraulic oil squirting out can lead to serious
injury.
►
When attaching the hydraulic attachment do not
lay any hydraulic lines through the carrier's cab.
►
Only use hydraulic lines which comply with the
following quality requirements:
Hydraulic hoses with 4 reinforcement steel
wires according to DIN EN 856 4SH,
Hydraulic pipes, seamless cold-drawn steel
pipes to DIN EN 10305.
Special parts, precautions
HP-accumulator
DANGER Danger of explosions
The HP-accumulator of the hydraulic breaker is
filled with nitrogen (N
2
). Filling it with any other gas
may trigger an explosion and lead to serious,
possibly fatal, injuries.
►
Only fill the HP-accumulator with nitrogen (N
2
).
►
Do not carry out any welding and soldering
work to the HP-accumulator.
►
Check the HP-accumulator in accordance with
the national safety provisions.
WARNING Component coming loose
abruptly
Risk of bursting
The HP-accumulator is under pressure, even when
the hydraulic system has been depressurised.
Screw connections might come loose
unexpectedly and cause injuries.
►
Never unscrew the cover or the upper shell
from a pressurised HP-accumulator.
►
Never carry out mechanical processing to the
HP-accumulator.
Piston accumulator
DANGER Danger of explosions
The integrated piston accumulator is filled with
nitrogen (N
2
). Filling it with any other gas may
trigger an explosion and lead to serious, possibly
fatal, injuries.
►
Only fill the piston accumulator with
nitrogen (N
2
).
WARNING Component coming loose
abruptly
The piston accumulator is under pressure, even
when the hydraulic system has been
depressurised. The filling valve might come loose
unexpectedly and cause injuries.
►
Never unscrew the filling valve »G« from the
pressurised piston accumulator.
