Caution; Install Gate Bracket & Drive Chain - Chamberlain LiftMaster Professional SL575 Installation Manual

WARNING
INSTALL GATE BRACKET & DRIVE CHAIN

CAUTION

CAUTION
To prevent damage to the operator or gate, DO NOT drive the
limit (nuts) actuators on the shaft past their normal positions.
1. Mount gate brackets to the vertical front and rear posts of the
gate (Figure 1).
2. Remove the operator cover.
3. Locate and engage the manual disconnect and lock it in place
(refer to page 12).
4. Connect chain take-up bolt to the end of the chain and attach
to the rear gate bracket (Figure 2).
5. Ensure that the drive and idler sprockets are in line with each
other. Thread the chain through the plastic chain guide, around
drive and idler sprockets, and then through the second plastic
chain guide toward front gate bracket (Figure 3).
6. Adjust the chain to proper length and attach second take-up
bolt to chain end. Secure the take-up bolt to the front gate
bracket as shown.
Adjust nuts on chain take-up bolts to remove chain slack. A
general rule of thumb is to leave a maximum of 1" (2.5 cm) of
chain slack for every 10' (3 m) of chain length.
Do not overtighten chain.
NOTE ABOUT SOME TYPES OF CANTILEVER GATES:
With some cantilever gates over 20' (6 m) long, you may need to
add a brace along the length of the gate to prevent the gate from
bowing when chain is tightened. This may also be required on
some styles of gates that are constructed out of aluminum. If
positioned properly, this brace can also be used as a chain
support.
