Operator Preparation
Vent Plug Installation
In order to keep gear oil from spilling out during shipping,
gear reducers used in gate operators have either a solid
plug, or a sealed vent plug, installed at the factory.
For operators with a solid plug, replace the solid plug with
the vent plug provided (see Figure 3).
With the vent plug installed, remove the vent plug's breather
pin to allow the gear box to vent (see Figure 3).
Gate Arm Installation
The gate arm connects the operator to the gate. The arm
supplied can be used in left-hand or right-hand installations.
Gate Arm Assembly
Refer to Figure 4.
1. Remove the arm assembly cover.
2. Place the center hole in the rail guide over the 1" drive
shaft.
3. Place the drive sprocket on drive shaft. Be sure the
keyway is in place and set screws are secured.
4. Connect the gate bracket to the gate. Manually open the
gate to approximately half-open position.
5. String the arm assembly chain as shown in Figure 4.
✓ NOTE: Observe the way the chain threads around the sprockets for
left-hand or right-hand installations. Refer to Figure 4.
6. Adjust for taut chain tension but do not overtighten.
7. Replace the arm assembly cover.
