Hydraulic hoses
When checking for leaks, suitable aids should be used due to danger.
(Goggles, work gloves, a piece of cardboard that quickly detects
leakage, etc.) Thin splashes of hydraulic oil under high pressure can penetrate the skin
and cause serious damage. In case of injury of this kind, seek medical attention
immediately. INFECTION HAZARD.
Check the condition of all hoses by regular inspection. Pay particular attention
that they do not rub against edges, slideways, bolts, etc., and that the hose
sleeve is properly placed so that the hoses are always protected as good as
possible.
Check all hydraulic hoses and fittings daily. Any damage or leakage must be
repaired immediately. Hoses with defective metal bands must be replaced
GreenTec's hydraulic systems operate at very high pressure. Only use original
hoses. A blown hose can be very dangerous.
When replacing hoses, avoid twisting hoses and fittings. Use two wrenches to loosen and
tighten. Avoid excessive tightening. If fittings continue to leak, they must be replaced.
The warranty on the hoses is limited to replacement of hoses due to defective material or
fabrication. The warranty for hoses no longer applies if:
•
Hoses are damaged due to wear and tear
•
If the hoses have received a cut or have been jammed during work
•
If the thread is damaged due to excessive tightening.

A hose is
weakened when it is twisted during
assembly. That is why pressure
pulses in a twisted hose tend to
overload the steel wire and loosen
the connections. Fit hoses so the
machine's movements cause them
to bend rather than twist.
