Carton Inventory; Hardware Inventory; Site Preparation - Chamberlain RJO Owner's Manual

Your garage door opener is packaged with all parts illustrated below. If anything is missing, carefully check the packing
material. Hardware for assembly and installation is also listed below.
It is imperative that the wall or mounting surface provide ade-
quate support for the operator.
NOTE: The plywood shipping base supplied with the unit
may be used for this purpose. Securely anchor the shipping
base to the wall then mount the operator securely to the
base.
This surface must:
a) Be rigid, to prevent play between operator and
door shaft.
b) Provide a level base.
c) Permit the operator to be fastened securely,
with the drive shaft parallel to the door shaft.
The safety and life of the operator will be adversely affected
if any of the above requirements are not met.
