In China we "pull" the trigger altho to be pedantic the RFM does say to "hold" the trigger.
"hold" is to "pull" ????
The way I was trained many years ago (when a particular Canadian company took delivery of its first A+ ...yes it was an A+ not an ++ but same throttle) was that if the engine went hot and you had not "PULLED" the trigger ; in your panic to shutdown , you may well jam the throtttle up against the idle stop.....in any case the RFM says you may have to move the throttle back past the throttle idle stop in order to modulate the T5 during start , so why would you not pull the trigger.
The analogy to the above is the 212 where you can hit the idle release switch but if you have a death like grip on that throttle , you will not move it ie the force you are applying to close the twist grip is jamming the cam against the pin and not allowing it to retract thus not allowing closure of the throttle past idle.
The late Peter H. had somewhat similiar happen to him in Bombay on a 212 years ago (he also had a battery problem) and in his desire to stop that awful noise and ever increasing TOT , he pulled the Fire T Handle.....clean out of the instrument panel.
