2.4.7 Bolt the limit switch plates so they engage the limit switches' lever arms. The
plate must be located so that both limit switches are hit in the correct
sequence. The first limit switch tells the controller to slow the gate down.
The second limit tells the controller to stop the gate.
2.4.8 Grease or cosmoline needs to be added to the rack, pinion and wheel areas to
prevent oxidation. This should be checked and touched up during the
monthly maintenance as needed.
