CAUTION CAUTION PRESSURE TEST (CONT) PRESSURE TEST (CONT) In the event of a tachometer failure, a HAND THROTTLE lever positioned to full down is approximately 750 RPM. (18) Set engine speed to idle 750 RPM (TM 9-2320-366-10-1). (19) Position PTO switch to off (TM 9-2320-366-10-1). (20) Shut down engine (TM 9-2320-366-10-1).
