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.
Use extreme caution when handling heavy parts. Provide adequate support and use assistance
during procedure. Ensure that any lifting device used is in good condition and of suitable load
capacity. Keep clear of heavy parts supported only by lifting device. Failure to follow this warning
may result in death or injury to personnel.
Boom lift cylinder weighs 885 lb (402 kg). Lifting device must have sufficient capacity to lift cylin-
der. Failure to follow this warning may result in death or injury to personnel.
