Acer has determined that, in a number of Acer ES Series 5 (AES015) e-scooters, there is a possibility that a specific screw may not have been tightened enough to the required specification during production. As a result, it could gradually loosen during normal use. This initiative is designed to ensure optimal operational safety by providing customers with a service maintenance update.
Customer safety remains Acer’s highest priority. This service maintenance update is intended to help ensure the continued safe operation of your e-scooter. To support you in this process, we have prepared a brief, step‑by‑step instructional video demonstrating which screw to inspect and how to tighten it correctly.
