ReminderonTensionAdjusters
The Tension Adjusters are used as the last step to
lock, and the first step to release the gears.Never
fully tighten them during operations.The optimum
position is one just deep enough to rid any plays.
Hesitation in turning the Gear Switch by 90° means
theTensionAdjusterhasnotbeenloosenedenough.
