  • To turn the lights on/off, use the switch located on the main power cord.

Maintenance

Shaping and Fluffing

After initial assembly and each year thereafter, dedicate 45-60 minutes to shaping the tree. This involves gently separating and spreading the individual branch tips to achieve a full and realistic appearance. Work from the inside out and from the bottom up.

Storage

The hinged branch system allows branches to fold back in for convenient storage. Disassemble the tree in reverse order of assembly. Store the tree in its original box or a dedicated tree storage bag in a cool, dry place.

Troubleshooting

Lights Not Working

  • Ensure all tree sections are properly connected and the main power cord is securely plugged into a functional outlet.
  • Check for any loose or broken bulbs. While lights are designed to stay lit if one bulb burns out, a broken bulb lens can affect the circuit. Replace any damaged bulbs with the provided spares.
  • Check the fuses in the light plugs. Replace if necessary.
