Pull Force on Take-Up Lever

Measurement

  1. Ensure that the take-up lever of the current needle is at full “head-up” position.

  2. Using a force gauge (Melco PN: 995591-01), measure the amount of pull force it takes to lift the take up lever up to a point just before it hits a hard stop.  Do not allow the take-up lever to hit the hard stop or the measurement will be inaccurate.

Adjustment

If the measurement is not between 1.4 to 1.5 lbs, readjust the preload on the take-up lever spring.
