Too much force will cause improper operation of the safety reversal mechanism and
may cause serious injury. The higher the force is set the less sensitive the opener is
to detecting an obstruction.
▪
Force settings should only be adjusted by a suitable qualified technician.

The safety reversal system must now be tested by placing a 40mm high
object on the floor and ensuring the door reverses on contact, see page 9.
Adjust force again if necessary.
