ADJUSTING THE DRIVE HEIGHT
Adjusng the Drive Height
Raise the operator to the correct height so that it engages the tooth rack in the gate beam. Clearance
between the tooth rack and spur gear should be 0.11” (2.7mm); an 11ga e wire can be used as a gauge
to set the correct clearance. See Figure 4.

2.0” retaining bolts and lock nuts on spur gear. See Figures 5 and 6.
