After Repairing or Replacing the Components (continued)
4. Remove all the caps or plugs from the hydraulic tubes, hydraulic fittings, and
components before connecting them again.
5. Use proper tightening procedures when installing the hydraulic hoses and
fittings; refer to Installing the Hydraulic Hose and Tube (O-Ring Face Seal
Fitting) (page 6–11) and Installing the Hydraulic Fittings (SAE Straight Thread
O-Ring Fitting into the Component Port) (page 6–13) .
6. After you complete the repairs, check the control linkages or cables for
proper adjustment, binding, or broken parts.
7. After you complete the repairs, clean the hydraulic components, hose
connections, and fittings to prevent future accumulation of dirt and unwanted
material on the hydraulic components.
8. After you disconnect or replace any hydraulic components, operate the
machine functions slowly until the air is out of the system; refer to Charging
the Hydraulic System (page 6–151) .
9. Check for hydraulic-fluid leaks. Shut off the engine and repair leaks if
necessary.
10. Check the hydraulic-fluid level in the hydraulic tank and add correct quantity
of fluid if necessary.
Checking the Hydraulic Lines and Hoses
WARNING
Hydraulic fluid escaping under pressure can penetrate skin and
cause injury.
• Ensure that all hydraulic-fluid hoses and lines are in good
condition and all hydraulic connections and fittings are tight
before applying pressure to the hydraulic system.
• Keep your body and hands away from pinhole leaks or nozzles
that eject high-pressure hydraulic fluid.
• Use a piece of cardboard or paper to find hydraulic leaks.
• Release all pressure in the hydraulic system before performing
any work on the system.
• Seek immediate medical attention if hydraulic fluid is injected
into your skin.
IMPORTANT
Check the hydraulic lines and hoses daily for leaks, kinked
lines, loose mounting supports, wear, loose fittings, and hose
deterioration. Repair the damaged hydraulic lines and hoses before
operating the machine.
