One of the most common messages we receive at Yanming comes from forklift owners who already have our A1-WL weighing system installed on their trucks, yet have no idea who originally supplied it. A typical example:
"Hi Monica, we have several forklifts fitted with your A1-WL system and we require a user manual for this system and the default PIN for calibration. Can you send us this?"
This is a question we are always happy to answer. Whether your A1-WL system was purchased directly from us, inherited with a used forklift, installed by a local dealer, or sourced through an unknown channel, you are still part of the Yanming family — and we will support you.
Forklift weighing systems like the A1-WL are long-life industrial tools. Trucks get sold, fleets get merged, and maintenance records get lost. But a calibration PIN or a missing user manual should never stop your operation or put your weighing accuracy at risk. Our philosophy is simple: safe, accurate weighing should be available to every owner, not only to the original buyer.
