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
route 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 4SP and 4SH according to DIN EN 856,
Hydraulic hoses with high tensile steel wire
braid 1SN and 2SN according to DIN EN 853,
Hydraulic pipes, seamless cold-drawn steel
pipes to DIN EN 10305.
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.
►
Never use your hands to find leaks.
►
Always keep your face away from a possible
leak.
►
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.
►
Make sure not to spill any hydraulic oil.
►
Immediately clean the floor if you have spilt
hydraulic oil.
►
Observe all safety and environmental protection
provisions 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.
►
Avoid all skin contact with hydraulic oil and
grease.
►
Use a suitable skin protection product.
►
Always wear safety gloves when working with
hydraulic oil or grease.
►
Immediately clean any skin that has been
contaminated by oil or grease with water and
soap.
