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 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.
CAUTION
Wipe area clean around all hydraulic connections prior to disconnecting. Cap or plug all openings after dis-
connecting. Contamination of hydraulic system could result in equipment failure.
NOTE
Tag all hydraulic lines.
