__________________
 A. Check/Test
 (1) Before you start the APU for the operational test:
 - do a visual inspection and make sure that you do not find damage and/or unwanted material in the air intake system and/or on the engine air-intake screen (Ref. AMM TASK 49-16-00-210-001).

 - do a visual inspection and make sure that you do not find damage and/or unwanted material in the exhaust system and/or on the turbine exducer blades and stators (Ref. AMM TASK 49-20-00-200-001)

 NOTE : THE TORQUE LIMIT IS 29 lbf.ft (3.9318 m.daN). DO NOT TURN THE
____ SHAFT WITH A TORQUE MORE THAN THE LIMIT. A TORQUE MORE THAN THE LIMIT WILL DAMAGE THE COMPONENT.
 - turn the manual drive shaft of the starter motor (8KA) in a counterclockwise direction (in the direction of the arrow on the housing) and make sure that: . you can turn the manual drive shaft of the starter motor equally, . the APU rotors, bearings and gears do not rub, . the APU rotors, bearings and gears do not make unsual noise.
 NOTE : Turn the manual drive shaft of the starter motor with a torque
____ wrench. Make sure that the drag is 15 to 45 lbf.in (0.17 to 0.51 m.daN).
 (a) If you find that the drag of the APU rotors, bearings and gears is too much, they do rub or they make unsual noise, replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-001) and (Ref. AMM TASK 49-11-11-400-001).
 (2) Do the operational test of the APU (Ref. AMM TASK 49-00-00-710-004).
