Flight manual (350): Preflight Inspection Initial Cockpit Checks.
Trims: Checked
Caution: the elevator trim must not be forced past the limits...
a) elevator - set two units NU
b) Rudder and Aileron - set to zero units.
My operator does a full range of motion check on first flight of the day, regardless, the checklist speaks for itself in terms of bringing the rudder back to zero.
