Do:

  1. Slide the cam's lobe flat-face-down into the 4 mm pocket under the foot's drive end, hole over the foot's empty hole.
  2. Fit the second M5×10 BHCS through both and leave it loose: a pivot, not a fastener.

check Check

Tab free to swing about the screw; motor still free to slide along the extrusion; both M5×10 in the foot loose.

What you're looking at

Manual p.43: the blue [a]_belt_tensioner, a cam whose lobe lies in a pocket under the drive end of the motor foot. The lobe is eccentric: swinging the tab from upright to flat pushes the motor foot away and takes up the belt slack.

tip Tip

Flat face down, round lobe on your left: the upright tab is far-right on _a, near-right on _b. The wrong hand swings away from the motor.
