Page: 108 / 390

Work on chassis, braking and steering systems must only be carried
out by qualified personnel trained for such work.
Clean any traces of oil, fuel or preservatives from the machine, espe‐
cially connections and threaded unions, before carrying out mainte‐
nance or repair work. Do not use aggressive cleaning agents. Use
lint-free cleaning rags.
Bolted connections that you have loosened for carrying out mainte‐
nance and repair work must always be replaced or retightened in ac‐
cordance with manufacturer specifications.
Do not open gas-filled spring elements, as used on maintenance
flaps, for instance. The spring elements are filled with gas under high
pressure which can escape explosively if you attempt to open them.
Relieve the tension on systems under mechanical stress.
Be aware of hot functional fluids and surfaces (hydraulic fluid, hy‐
draulic fluid radiator, etc.).
Ensure that all functional fluids, consumables and replaced parts are
disposed of safely and with minimum environmental impact.
3.2 Welding
Only carry out welding, flame cutting and grinding operations on the
machine once this has been expressly approved by the manufacturer.
Only qualified personnel may carry out welding work in line with man‐
ufacturer specifications, especially on the placing boom, on the sup‐
ports, on load-bearing parts, on fuel and oil tanks or other compo‐
nents which are important for industrial safety. This work must be in‐
spected by qualified welding personnel. The operator must document
the evidence of the formal qualifications of the welder and the quali‐
fied welding personnel.
Always attach the earth cable of the welding unit directly to the com‐
ponent which is being welded. The welding current must not flow
through hinges, cylinders, etc. Significant damage may be caused in
the event of a flash over.
