2. Safety Information
Always prioritize safety when operating electrical equipment. This charger incorporates several safety features:
- Overvoltage Protection: Prevents charging at excessively high voltages.
- Overcurrent Protection: Safeguards against drawing too much current.
- Overheating Protection: The charger automatically shuts down if the temperature is too high and resumes when cooled.
- No-Load Protection: No output is provided without a battery connection.
- Battery Reverse Polarity Protection: Prevents damage from incorrect battery terminal connections.
- Output Short Circuit Protection: Cuts off internal circuits to avoid damage in case of a short circuit.
Ensure adequate ventilation during charging. Do not expose the charger to water, volatile gas, or open flame. Do not cover the charger during operation as it relies on its heat sink for cooling.

3. Setup
Follow these steps to set up your CMTOOL battery charger:
- Prepare the Battery: Ensure the 24V lead-acid battery is clean and free from corrosion on its terminals.
- Connect Battery Terminals: Attach the provided terminal pins to your battery's positive and negative posts. Ensure a secure connection.
- Connect Anderson Plug: Connect the Anderson plug from the charger to the battery's Anderson connector. The charger comes with a spare plug connector and terminal pins for wider use.
- Connect AC Power: Insert the 110V plug into a standard power outlet.
The charger will perform a 3-second self-test before initiating the charging process.

4. Operating Instructions
The CMTOOL charger operates with a 7-stage smart charging process, automatically adjusting voltage and current to optimize charging and prevent overcharging. It includes a 3-color indicator light for easy status monitoring.
4.1. Indicator Light Status
- Red and Green Flash: Waiting mode or no-load condition.
- Red Flash: Low charging (battery charge < 80%).
- Yellow Flash: Normal charging (battery charge > 80%).
- Green Flash: Trickle mode (maintaining charge).
- Green On: Fully charged (100%).

5. Maintenance
The CMTOOL charger is designed for durability and minimal maintenance:
- Cooling Fan: A built-in cooling fan ensures stable operation and prevents overheating. Keep the fan vents clear of obstructions.
- IP67 Rating: The IP67 waterproof and dustproof rating means the charger is protected against dust ingress and temporary immersion in water. This makes it suitable for outdoor use and various environments.
- Temperature Resistance: Designed to operate in a wide temperature range (-20℃ to +45℃), adapting to diverse working conditions.
- Durable Construction: The aluminum body provides robust protection against daily wear and automotive-grade shock.

6. Troubleshooting
If you encounter issues with your charger, refer to the indicator light status and the following common troubleshooting tips:
- Charger Not Activating (Red/Green Flash): Ensure the battery is properly connected and has sufficient voltage for the charger to detect it. Check all cable connections.
- No Charging Output: Verify that the AC power cord is securely plugged into a live outlet. Check for any loose connections at the battery terminals or Anderson plug.
- Overheating Shutdown: If the charger shuts down due to high temperature, allow it to cool in a well-ventilated area. Ensure the cooling fan is not obstructed.
- Slow Charging: Confirm that the battery type is compatible with the charger. Ensure the battery is not severely discharged or damaged.
