level. If required, adjust the turnbuckle as follows:
1. Make sure the unit power switch is off.
2. Rotate the gearbox pulley by hand until the crank arm is in parallel with the turnbuckle shaft
at its lowest point of travel (see Figure 7).
3. If the gate arm is not level, loosen both turnbuckle jam nuts and rotate the shaft until the gate
arm is parallel with the ground, then retighten the two jam nuts.
