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 pene-

trate the skin, causing serious injury.

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

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 oil is hot. Allow hydraulic oil to cool before disconnecting any hydraulic

lines. Failure to do so could result in injury.

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

injury to personnel.
