The gap between the rotary hook support and the back wall of the inner basket notch of the rotary hook should be a minimum of 0.18” - .022" [0.46mm - 0.5mm] [use fixture number 009027-01].
In most cases, this gap is adjusted by loosening the screws on the rotary hook support bracket and adjusting the gap. If this does not work, reset the rotary hook and retime it using the procedures explained in this manual.
