2.1 Declaration of symbols
T is operating and maintenance instruction manual contains important notes and symbols, w ic are
to be considered and followed. T ese include:
 DA GER
Danger emphasizes operating and service procedures that if not avoided,
may lead to death or serious personal injuries.
 WAR I G
Warnings emphasize operating or service procedures, or conditions that
can result in serious personal injury or death.
 CAUTIO
Cautions emphasize operating or service procedures, or conditions that
can result in equipment damage or impairment of system operation. If not
avoided, light or medium body injuries could be the consequence.
NOTE
otes provide additional information that can expedite or improve operat-
ing or service procedures.
Danger symbol wit out key word: Additional notes
2.2 General warning notes
Using of t e Swivel Joint, t e following warnings are to be considered.
T e specified warnings are not only restricted to t e operation wit t e maximal
permissible operating pressure of 4150 bar / 60,000 psi or 6200 bar / 90,000
psi. T ey are also valid on work wit reduced operation pressures!

 DA GER
Danger of cutting of extremities on contact with waterjet
T e contact wit t e ig kinetic energy performing waterjet can ave t e conse-
quence of cutting of extremities or lead to ot er injuries.
Therefore:
 Operate t e mac ine only, w en nobody stands in t e danger zone of t e
waterjet.
 Never touc t e waterjet, not even wit personal protective equipment.
 Always maintain a sufficient safety distance from t e swivel joint w en it is
pressurized.
Any injuries in connection wit t e waterjet, alarm t e emergency doctor imme-
diately.
 CAUTIO
Danger of breathing difficulties and irritation of the skin and eyes by re-
leased solid particles or dust.
During mac ining of certain material, solid particles and dust may float in t e air,
w ic could cause breat ing difficulties and irritations to t e skin and eyes.
Therefore:
 Ensure t e proper ventilation of t e room surrounding t e mac inery.
 Ensure to wear t e personal protective equipment (protection glasses,
breat ing mask, gloves, …)
Additionally, t e rules and regulations of t e working place are to be followed to
prevent injuries!
2.3 Intended use
T e Swivel Joint is designed for t e transmission of rotary movements. T e swivel joint must be firmly
attac ed to t e mac ine. Only pure water may be used as working fluid. T e tec nical limit values
must always be observed.

2.4 Inadmissible usage
Inadmissible usage of t e Swivel Joint includes:
 T e usage of all ot er fluids ot er t an water
 T e addition of ot er substances to t e water
 Closure of t e pressure relief oles
 Excessive application of t e Swivel Joint
