English to French Tech/Engineering Automotive / Cars & Trucks disc spring starter

In user hadbook for disc spring starters.
When starting for the first time:

"When engine starts, adjust the throttle to the desired level. Make a note of the number of winds made when the engine started and mark on the quick reference operator’s instructions label as the ‘advised number of winds for starting’. "


I'm not sure if winds should be translated simply as "tours" (done with a winding handle) or rather as "enroulements" (and hence winding/unwinding as enrouler/dérouler but we are talking of springs here, not some kind or cord) or even as (serrer/desserrer)...
