•
Ensure all connections are tight and hoses are in good condition before applying pressure to the system.
•
Check hydraulic cylinders for leaks and damage. Repair or replace as required.
•
Examine condition of hoses. Check for leaking hoses, kinked hoses, and for hoses that rub against other
hoses or other parts of the machine.
•
Replace all deteriorated or damaged hoses. When a hose with a protective sleeve is replaced, always install
a new protective sleeve over the new hose.
WARNING:
Pressurized fluid can penetrate body tissue and result in serious injury or death.
Leaks can be invisible. Keep away from any suspected leak. Relieve pressure in the
hydraulic system before searching for leaks, disconnecting hoses, or performing any other
work on the system. If you must pressurize the system to find a suspected leak, use an object
such as a piece of wood or cardboard rather than your hands. When loosening a fitting where
some residual pressure may exist, slowly loosen the fitting until oil begins to leak. Wait for
leaking to stop before disconnecting the fitting. Fluid injected under the skin must be
removed immediately by a surgeon familiar with this type of injury.
