"Running at creep" on JLG ADE Boom Lifts

Models Affected : JLG® Boom Lifts

“Running at creep, creep switch open” is not a code that signals a problem. The code simply alerts the operator that the creep switch is activated, and this alert will also be accompanied by an illuminated green indicator light on the platform display. Integrated into the rotary speed control on the platform display, the creep switch is activated by turning the knob all the way to the left until it clicks. At this point, the “Running at creep” code will display. Keep in mind that this code is not related to any limited switches and is limited to the rotary speed control knob.
