TOP AND BOTTOM BEAM AND HYDRAULIC LIFT
CYLINDER REMOVAL / INSTALLATION (Con't).
Escaping hydraulic fluid under pressure can pen etrate the skin, causing serious
injury to personnel. Relieve pressure before disconnecting hydraulic lines and
fittings. Tighten all connections before applying pressure. Keep hands and body
away from pinholes and nozzles that eject hydraulic fluid under high pressure.
Use a piece of cardboard or paper to search for leaks. If any hydraulic fluid is
injected into the skin, it MUST be surgically removed within a few hours by a
doctor familiar with this type of injury or gangrene may result.
