__________________
 A. Do this test.

 (1) Make sure that the PTU P/BSW is in the AUTO position.

 (2) Start the engine No. 1 (Ref. AMM TASK 71-00-00-710-003).

 (3) Start the engine No. 2 (Ref. AMM TASK 71-00-00-710-003).

 (4) Do a check of the PTU for continuous running.

 (a) If there is continuous running, do the subsequent steps: 1 On the overhead panel 40VU, set the GREEN/ENG 1 PUMP P/BSW to
_ the OFF position, and after some seconds, back to the ON position.
 2 Do again a check for continuous running of the PTU.
_

 (5) Shut down the engines (Ref. AMM TASK 71-00-00-710-028).
