WARNING Hydraulic pressure too high
If the hydraulic pressure is too high, the parts of the hy-
draulic attachment will be exposed to excessively high
loads. Parts can break loose or burst causing serious in-
juries.
u Lay the drain line of the pressure relief valve directly
in the tank to ensure the safe functioning of the pres-
sure relief valve!
u The pressure relief valve must be set at the maxi-
mum static pressure.
u The pressure relief valve setting must be checked to
ensure that the maximum static pressure (see chap-
ter Technical specifications) of the hydraulic instal-
lation is not exceeded at any time. Attach a lead seal
to the pressure relief valve.
u Prior to their first use, the safety facilities on the hy-
draulic installation must be checked by a profes-
sional/authorised monitoring body for their quality
(CE mark etc.), suitability and proper functioning.
u 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.

The hydraulic system is under high pressure. Hydraulic
lines may spring a leak or burst. Hydraulic oil squirting
out can lead to serious injury.

lowing quality requirements:
- Hydraulic hoses with 4 reinforcement steel wires
according to DINEN856 4SH,
- Hydraulic pipes, seamless cold-drawn steel pipes
