WARNING

DO NOT disconnect or remove any hydraulic system line or fitting unless hydraulic system pressure

has been relieved. Tighten all connections before applying pressure. Escaping hydraulic fluid under

pressure can penetrate the skin, causing serious injury.

Search for leaks with a piece of cardboard. Protect hands and body from high-pressure fluids. If an acci-

dent occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed

within a few hours or gangrene may result.

At operating temperature, hydraulic fluid is hot. Allow hydraulic fluid to cool before disconnecting any

hydraulic lines. Failure to do so could result in serious burns.

Hydraulic fluid is very slippery. Immediately wipe up any spills. Failure to follow this warning may

result in injury to personnel.
