1.4 Chain Installation
1. Secure the chain brackets to each end of the
gate so that the brackets are level with the
top chain cutouts in the operator housing.
Brackets should be attached to the inside of
the frame so that the chain bolts, when
attached, do not protrude beyond the frame
of the gate.
2. Remove the breather plug pin from the
gear-box and discard it (page 17).
3. Route the chain through the gate operator:
under the chain guide idlers and over the
drive sprocket.
4. Attach the chain to the chain bolts using the
master links supplied, and then attach the
chain bolts to the chain brackets using the
hardware supplied. Make any adjustments to
the chain length at this time.
5. Adjust the chain bolts to tighten the chain.
The chain should sag no more than one (1)
inch per 10 feet of travel. Do not over tighten
the chain. IMPORTANT!! Be sure that the
chain is parallel to the gate. Installing the
chain in any other manner will cause
excessive noise, chain idler wear and
chain stretching.
6. If the operator is to be rear mounted, an
endless idler assembly (P/N 2600-818) is
required. Depending on the length of the
gate, additional chain may also be required.
