Using your Greenlee ES20LXR11 is a breeze. First, make sure the batteries are fully charged using the 120V charger. You can either use the cutter remotely with the included remote control or hold it in your hand. When using remotely, connect the remote via Bluetooth. To cut wires, place the wire in the cutting head and activate the cutter. The cutting head can rotate 350 degrees, so you can easily reach the right angle. Make sure to use it within the operating temperature range of 1 F (-17 C) to 104 F (40 C). Keep it away from water and extreme humidity. After each use, wipe it down to remove any dirt or debris. Check the batteries regularly and replace them when needed. The cutter uses bio - degradable oil, so no need to worry about environmental harm. Enjoy the 84 - month warranty for peace of mind.
