MODEL BG790 ADJUSTMENTS

1If necessary, rotate the pulley on the motor by hand until the upper and lower cranks are in a vertical position (see Figure 13). This is the lowest point of travel and should be preset in this position at the factory.

2If the arm is not level, loosen the jam nuts on both the top and bottom end of the turnbuckle shaft.

3Rotate the shaft either CW or CCW as necessary until the gate arm is in the desired horizontal position.

NOTE: While the arm is raising, the upper and lower cranks should travel toward the side access cover.
