Maximum gap – 1/8" (0.30 cm)

idler pulley on each side.
d) Relieve pressure on the spring-loaded idler pulleys, and be sure the
stationary idler does not move.
e) Reposition the guide as necessary to achieve the proper gap and tighten the nut.

have the correct measurement. Repeat as necessary on both sides of the unit.
