It also stated that the Check list states that due to elastomerics in the rotor head the collective will be partially up, and to NOT attempt to lower until there is hydraulic pressure.
The S92 is the same. Here's the note I wrote in our Ops Manual Pt B 12 years ago.......
Prior to rotor engagement, the collective will rest in a midrange position. Monitor collective position during initial rotor engagement. As Nr increases through approximately 20% and hydraulic pressure increases, the CM2 shall depress the collective trim switch and move the collective to the full down position.. Avoid using the collective trim switch until hydraulic pressure builds.
(CM2 is the RHS pilot)
On top of that, with CT-7 engines (not sure if this variant is CT-7 or RTM 322) you can do the entire engine rinse and dry procedure without engaging the rotor!
Pity the same lessons have to be relearned!
