Maintenance
These devices require little maintenance, but routine visual
inspection is recommended to keep foreign debris from
collecting on the exterior actuators and rollers.
Removing the operator head is not recommended as loose
internal components may be lost or improperly re-installed.
Actuation Guidelines
The method of actuation and over travel has significant
influence on the service life of the limit switch. To maximize
the service life, it is recommended to provide an actuator with
a 30° pressure angle and a surface hardness of RC-45 max.
ATTENTION
Under no circumstances must the switch be actuated
beyond the mechanical travel specified. Serious
damage to the device and property could result.
