2.8 Hydraulic installation,
precautions
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.
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.
u When attaching the hydraulic attachment do not
route any hydraulic lines through the carrier's cab.
u Only use hydraulic lines which comply with the fol-
lowing quality requirements: Hydraulic hoses with 4
reinforcement steel wires 4SP and 4SH according to
DINEN856, Hydraulic hoses with high tensile steel
wire braid 1SN and 2SN according to DINEN853,
Hydraulic pipes, seamless cold-drawn steel pipes to
DINEN10305.
2.9 Media/consumables,
precautions
WARNING Hot hydraulic oil under high pressure
Hydraulic oil will squirt out under high pressure if there is
a leakage. The jet of oil might penetrate people's skin
and cause permanent damage. Hot hydraulic oil can
cause burns.
u Never use your hands to find leaks.
u Always keep your face away from a possible leak.
u If hydraulic oil has penetrated your skin consult a
doctor immediately.
WARNING Hydraulic oil spills
Spilt hydraulic oil can make a floor slippery. If people slip
they can be injured. Hydraulic oil is environmentally
harmful and must not penetrate the ground or enter the
water table or water supplies.
u Make sure not to spill any hydraulic oil.
u Immediately clean the floor if you have spilt hydraulic
oil.
u Observe all safety and environmental protection pro-
visions when handling hydraulic oil.
WARNING Skin infections/diseases due to oil and
grease
Hydraulic oil and grease can cause rashes (or even
eczema) if they come into contact with the skin.
u Avoid all skin contact with hydraulic oil and grease.
u Use a suitable skin protection product.
u Always wear safety gloves when working with hy-
draulic oil or grease.
u Immediately clean any skin that has been contami-
nated by oil or grease with water and soap.
