Charging Instructions

• Important Notes about Charging:

  1. Continuous operation below 20% battery level will shorten battery lifespan. Charge promptly when low. Charge immediately when battery level below 20%.

  2. If idle, charge the battery at least once per month to avoid battery deterioration.

  3.Full charge requires 6–8 hours; display will show 100% upon completion. If the  stacker is started without being fully charged, it will still display the battery level before charging.

  4. ERR31/ERR32 are battery over-discharge protection reminders. Once displayed,  stacker must shut down and charge immediately!
