Checking the hydraulic system for leaks
Safety instructions regarding pressure line checks
Burn and injury hazard if hot hydraulic oil escapes under high
pressure!
Hydraulic oil escaping under high pressure can catch fire, damage
property, penetrate the skin, and cause serious burns.
► Do not operate the machine with leaking or damaged hydraulic system
components.
► Never search for leaks with your bare hands, wear protective gloves
and clothes.
► Wear safety glasses to protect the eyes. If oil contacts the eye flush
immediately with clean water and seek medical treatment.
► Seek immediate medical attention if oil penetrates the skin. Oil can
cause serious infections.
► Retighten leaking threaded fittings and hose connections only when
the hydraulic system is not under pressure. In other words, release the
pressure before working on pressurised lines.
► Never weld or solder damaged or leaking pressure lines and hardware.
Have damaged parts replaced with new ones by a qualified and
authorized service center.
► Do not check for leaks with an open flame due to explosive fire risk
from vaporised oil mist.
