Allied Systems H4A Operating Manual page 13

• Be aware of the hazards of pressurized hydraulics:
»
Wear personal protective equipment, such as
gloves and safety glasses, whenever servicing
or checking a hydraulic system.
»
Assume that all hydraulic hoses and components
are pressurized. Relieve all hydraulic pressure
before disconnecting any hydraulic line.
»
Never try to stop or check for a hydraulic leak
with any part of your body; use a piece of
cardboard to check for hydraulic leaks.
»
Small hydraulic hose leaks are extremely
dangerous, and can inject hydraulic oil under
the skin, even through gloves.
»
Infection and gangrene are possible when
hydraulic oil penetrates the skin. See a doctor
immediately to prevent loss of limb or death.
