[2] Adjusting the Tension
Adjust the tension using the affixing bolts in the pulley bracket on the counter-motor side.
1) Move the slider to the motor-side mechanical end.
2) Loosen the affixing bolts (using a hex wrench of 3mm across flats).
3) Guide a wire around the bracket and pull the wire uniformly from both ends using tension
gauges.
4) With the wire pulled to a specified tension from both ends, tighten the affixing bolts carefully by
making sure the bracket does not deform. The appropriate tension varies depending on the
stroke.
