STEP 3
ATTACH THE CHAIN
Refer to the Appendix for rear installation step 3, page 35. DO NOT run
the operator until instructed.
1. Manually open the gate and line up the front bracket so the chain will
be level with the idler pulley and parallel to the ground. Weld the front
bracket in this position.
2. Manually close the gate and line up the rear bracket so the chain will
be level with the idler pulley and parallel to the ground. Weld the rear
bracket in this position.
3. Route the chain through the operator.
4. Connect the chain to the brackets using the eye bolt hardware. Chain
should not be too tight or have excessive slack.
NOTE: The chain should have no more than 1 inch of sag for every 10
feet of chain length.
