carbon deposits from the body. Such a condition must be corrected before further turbine opera-
tion. Record findings on Inspection Form PGS/GT–FF–WS27.

This will shorten the time required in the cleaning tank.
CAUTION
Do not use metallic scrapers, pen knives, or wire brushes
to remove carbon from fuel metering passages.
3. A typical cleaning and rinsing facility is shown in Figure CI-I.5. Immerse the parts in a clean solu-
tion like those suggested in Table CI-1, and allow the parts to soak at the solution temperature rec-
ommended by the supplier until clean. Follow the manufacturer’s instruction for use, the tempera-
ture required and the safety precautions to be observed.
Ultrasonic cleaning equipment may also be used to clean fuel nozzle parts. Consult ultrasonic
equipment manufacturer for cleaning equipment recommendations, cleaning solution to be used,
temperatures required and the safety precautions to be observed.
