How to use

Connect the adapter to a suitable mains outlet using the supplied mains lead or an appropriate regional power cord. Attach the adapter's DC output plug to the compatible input on the tool or charger until it is fully seated. Ensure the tool or charger specification matches an 18V DC input and that the device accepts up to 3A current. Monitor the adapter during initial use to confirm correct operation and allow for ventilation around the adapter housing to prevent overheating.

Usage recommendations

Use this adapter only with devices that specify an 18V DC input and can operate safely at up to 3A. Avoid using extension cords that may reduce input voltage or impede cooling. Keep the adapter in a dry, well-ventilated area, and disconnect from mains power before cleaning or long-term storage. For battery charging, follow the battery and charger manufacturer guidelines to ensure proper charging cycles and battery health.
