DISCONNECT
Figure 7
MODEL SL580 – Slide out the lock bar located underneath the cover and remove the cover.
Pull the disconnect chain and engage it in the slot provided. The gate may now be moved
manually.
To re-engage the operator, release the chain from the slot. The lock bar has provisions for a
padlock to prevent tampering with the operator.
MODEL SL590 – Open the hinged door and pull the disconnect lever and lock it in place.
The gate may now be moved manually.
To re-engage the operator, release the lever and close the door. The door has provisions for
a padlock to prevent tampering with the operator.
NOTES: On both models, when the operator is under load, you may find it necessary to
relieve the tension on the drive chain before disengaging the system. This may be
accomplished by firmly applying pressure in a downward motion to the drive chain with
your foot. You may also relieve pressure by rotating the external gear reducer shaft,
extending through the brake.
Manual Disconnect does not prevent motor from running.
