4. Operating Instructions
Once the Ferrex 20V battery is securely connected to the Bosch 18V tool via the FE20BS adapter, the power tool can be operated according to its original manufacturer's instructions. The adapter facilitates the power transfer from the Ferrex battery to the Bosch tool.
Important Note: This adapter is solely for power conversion and does NOT support battery charging. Do not attempt to charge the Ferrex 20V battery through the adapter or while it is connected to the adapter. Always remove the battery from the adapter and use the original Ferrex battery charger for charging.
5. Maintenance
- Cleaning: Keep the adapter clean and free from dust, dirt, and debris. Use a dry, soft cloth to wipe down the surfaces. Do not use liquid cleaners or solvents.
- Storage: Store the adapter in a dry place, away from direct sunlight, moisture, and extreme temperatures. For prolonged storage, it is recommended to separate the adapter from the battery.
- Inspection: Periodically inspect the adapter for any signs of damage, cracks, or wear on the connectors. If any damage is observed, discontinue use immediately.
6. Troubleshooting
- Power Tool Not Activating:
- Ensure the Ferrex 20V battery is fully charged.
- Verify that the Ferrex battery is securely attached to the FE20BS adapter.
- Confirm that the adapter and battery assembly is securely inserted into the Bosch 18V power tool.
- Check if your specific Bosch 18V tool model is compatible with this adapter.
- Adapter Not Fitting Correctly:
- Ensure you are attempting to connect a Ferrex 20V lithium battery to the adapter and the adapter to a Bosch 18V series power tool. This adapter is not designed for other battery or tool brands/voltages.
- Inspect both the adapter's ports and the battery/tool interfaces for any obstructions or debris that might prevent a proper connection.
7. User Tips
- Confirm Tool Compatibility: While designed for Bosch 18V series tools, it's always a good practice to visually compare the adapter's tool interface with your specific Bosch 18V tool's battery port to ensure a perfect fit, especially for specialized Bosch lines like 'Home & Garden'.
- Charging Protocol: Always remove the Ferrex 20V battery from the adapter before placing it on its dedicated Ferrex charger. The adapter does not facilitate charging and could potentially damage the battery or charger if left connected during charging.
- Optimal Storage: For maximum longevity of both your battery and adapter, store them separately when they are not in active use for extended periods. This prevents any potential minor discharge or stress on the connections.
