5. Operating Instructions

Once properly connected, the Kircuit AC/DC Adapter will begin to supply power to your Tomyvic leaf blower. This allows you to operate the leaf blower directly from an electrical outlet or to charge its internal battery.

• Battery Voltage Note: The 21V specification often refers to the leaf blower's battery voltage, not the charger's direct output voltage. This adapter is specifically designed to provide the correct charging parameters for 21V 2.0Ah Li-ion batteries used in the compatible Tomyvic models.
• Charging Indication: Refer to your leaf blower's user manual for specific charging indicators (e.g., LED lights) to determine when the battery is fully charged.

6. Maintenance

Proper care will extend the life of your adapter:

• Cleaning: Disconnect the adapter from all power sources before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
• Storage: Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures when not in use. Avoid wrapping the cord too tightly around the adapter body.
• Inspection: Periodically inspect the adapter and cord for any signs of damage, such as cuts, fraying, or bent prongs.

7. Troubleshooting

If you encounter issues with your Kircuit AC/DC Adapter, refer to the following common solutions:

• Device Not Powering On or Charging:
  • Ensure the adapter is firmly plugged into both the wall outlet and the leaf blower.
  • Verify the wall outlet is functional by testing it with another device.
  • Check the leaf blower's battery. Rechargeable batteries have a limited lifespan (typically 1 to 3 years). If the battery is old or faulty, it may not accept a charge, which is not an adapter issue.
  • Confirm that the adapter is the correct model for your specific Tomyvic leaf blower (TYLB001, TY-LB001, TYLB004, TY-LB004).
• Adapter Feels Warm During Use:
  • It is normal for the adapter to become slightly warm during operation. If it becomes excessively hot, emits smoke, or produces unusual odors, unplug it immediately and discontinue use.
