Setup
- Unpacking: Carefully remove the charger from its packaging. Inspect the charger for any signs of damage during transit. Do not use the charger if it appears damaged.
- Power Connection: Connect the charger's power cord to a standard 120V AC power outlet. Ensure the outlet is easily accessible and properly grounded. The charger is designed for 120 Volts input.
- Placement: Place the charger on a stable, flat surface in a well-ventilated area, away from direct sunlight, heat sources, and moisture. Ensure adequate space around the charger for air circulation, which is crucial for its air-cooled function.
Operating Instructions
The Metabo ASC 145 charger utilizes advanced technology for optimal battery charging and longevity.
- Inserting the Battery Pack: Slide the Metabo 12V-36V slide-on battery pack firmly into the charging slot on the charger. Ensure it clicks securely into place.
- Charging Process: The charger will automatically begin the charging process. It features a microcontroller that constantly monitors voltage flow, temperature, and maximum temperature. The charging current is 6.5 Amps.
- Air-Cooled Function: During charging, the patented air-cooled system actively cools the battery pack. This ensures the battery is maintained at an optimum temperature, which significantly extends the battery pack's service life and allows for up to 30% shorter total charging times.
- Charging Completion: The charger will automatically terminate the charging process once the battery pack is fully charged. This prevents overcharging and further contributes to battery longevity.
- Compensation Charge: To maintain the battery's capacity and health, the charger will switch to a compensation (maintenance) charge after the main charging cycle is complete.
- Removing the Battery Pack: Once charging is complete, press the release button (if applicable) and slide the battery pack out of the charger.
Maintenance
- Cleaning: Disconnect the charger from the power supply before cleaning. Use a soft, dry cloth to wipe down the exterior of the charger. Do not use abrasive cleaners, solvents, or immerse the charger in water. Ensure the ventilation slots remain clear of dust and debris to maintain the air-cooled function.
- Storage: When not in use, store the charger in a clean, dry place, away from extreme temperatures and direct sunlight.
- Inspection: Periodically inspect the power cord and charger housing for any signs of damage. If any damage is found, discontinue use and contact Metabo service.
