WARNING
DO NOT disconnect or remove any hydraulic system line or fitting unless hydraulic system pres-
sure 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 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.
CAUTION
Wipe area clean around all hydraulic connections prior to disconnecting. Cap or plug all openings
after disconnecting. Contamination of hydraulic system could result in equipment failure.
NOTE
Tophandler twistlock cylinders are replaced in the same manner.
Note direction of cylinder during removal to aid in installation.
Tag all hydraulic lines.
