GaTe OpeRaTIOn
The gate must roll freely with no binding of the wheel, guides, and/or gate hardware before any operator is
connected to the gate.
paD anD OpeRaTOR lOCaTIOn
Position the pad as indicated in Figure #1. Failure to do so may cause erratic operation resulting in reduced
operator life.
Important: If the gate is not at least twenty-eight inches longer than the opening, an extension should be added
to the rear portion of the gate fir the mounting of the rear chain bolt bracket. See Fig #2 The
extension must be rigid and long enough to allow the gate to fully close without the rear chain bolt
bracket hitting the operator.
Note: If there is already concrete where the operator is to be mounted, a pad is not necessary, if the existing
concrete is level.

Y dimension in Figure 2 must be high enough so that water will not stand under the operator in a worst case
scenario.
Soil conditions may vary but in sandy or loose soil the pad should be at least 18”-24” inches deep.
