INSTALLING SAFETY COVERS ON THE OPERATOR
The movement of the gate arm assembly presents the possibility of physical injury to installers, maintenance
technicians, and consumers/end users. The installer must know the areas of the operator where a person’s hands and
fingers could be pinched. Furthermore, the installer must take reasonable precautions when installing a gate operator
to prevent this type of injury (UL 325; 51.8.4 [a], [3]). GTO requires safety covers to be installed over the “pinch
points” of the gate operator. In particular, the upper and lower splines, the knuckle joint of the gate arm assembly, and
the operator itself must be covered.
Remove the gate arm assembly from the gate operator before attempting to install the safety covers. Detach the gate
bracket from the support bar and remove the

” bolt from the spline retainer. Lift the upper spline and the gate arm
assembly (as a unit) off the output shaft of the gear reducer. NOTE: check to make sure the knuckle cover and
its bolts are still in place (see page 14). In addition, make sure the safety edges, warning signs, and pedestrian gate
(if necessary) are installed (review pages 6-7).
