Clean the operator as needed.
5. It is suggested that while at the site voltage readings be taken at the operator. Using a Digital Voltmeter, verify that the incoming
voltage to the operator it is within ten percent of the operators rating.

on contact with a rigid object or stop when an object
activates the non-contact sensors. After adjusting the
force or the limit of travel, retest the gate operator.
Failure to adjust and retest the gate operator properly
can increase the risk of INJURY or DEATH.
