Can the actuator be used for continuous operation?
Recommendation should be obtained from the Duff -Norton Company on this type application and a completed application analysis form submitted. In general, semicontinuous operation can be permitted where load is light as compared to actuator model rated capacity. Units so used should be lubricated frequently and protected against dust and dirt. The Duff -Norton 7500 Series, oil-lubricated, high duty cycle actuator is designed for maximum duty cycles.
