WARNING
Turbine fuels are very flammable. They may cause drying and irritation of skin or eyes.
Handle only in wellventilated areas away from heat and open flame. Drain and store in
approved metal safety containers. Avoid prolonged or repeated contact with skin and
do not take internally. Wash contacted area of skin thoroughly after handling. If irrita-
tion of skin results, get medical attention. Get medical attention for eyes.
NOTE
Ensure that maximum power trim stop is installed when adjusting or checking maximum speed
setting. Ensure that maximum power trim stop is removed after adjustment or check is com-
pleted.
NOTE
Ensure that linkage systems are properly set prior to making fuel control adjustments. (Ref. TM
55152024023 or TM 55492032813).
NOTE
Maximum and ground idle speed settings of compressor rotor are interacting. Adjustment of one
requires a compensating adjustment to the other. To allow for backlash in adjustment screw, al-
ways approach final setting in counterclockwise direction.
