Hydraulic Hoses and Fluid Lines
Look for wear, damage, and signs of leaks. Ensure that clamps and fittings are tight. Wet spots indicate leaks, but
a stain around a fitting or connector can also mean a leak. If a leak comes from a loose fitting or connector,
tighten it. If something is broken or worn out, correct it if authorized by the Maintenance Allocation Chart
(WP 0109). If not authorized, notify your supervisor.

definitions of the types/classes of leakage you need to know to be able to determine the status of your equipment.
Learn and be familiar with them, and remember when in doubt, notify your supervisor.
