F requently Asked Questions

2 4 B
Q. What will happen if I mount the surface-applied operator at a center line (1) to center line (2) dis-
tance different than the one recommended?
A. It will alter the manual push open force. Mounting the operator closer to the hinge gives the
operator less leverage (power) to open the door, and thus lowers the manual push open force. It also
lowers the amount of spring force available to close the door and hold it closed. Mounting the
operator further from the hinge has the opposite effect.
Note!
Mounting the operator at any distance other than the recommended distance CL1 to CL2 in this
manual (reference section titled, "Surface Mount Installation") can damage the operator or exceed
ANSI/ BHMA requirements.
Q. Why does my door arm slip?
A. Because the slot in the main arm and the slot in the shaft adapter was not lined up as on the
illustration, see picture reference section titled, "Arm Systems (Surface Applied).
