Using this Athearn SD60I locomotive is easy. First, make sure you have the right power source. If you're using DC, the engine, horn, and bell sounds will work right away. For DCC operation, connect it properly using the 21 - pin NEM connector. You can control the locomotive's speed and functions easily. When programming a multiple - unit (MU) lashup, set it up so that only the lead unit has horn, bell, and light control. As for maintenance, keep it clean. You can use a soft brush to remove dust from the body, wheels, and handrails. Avoid getting the electronic parts wet. If you notice any loose parts, check the replacement parts available and make the necessary repairs. Store the locomotive in its packaging to keep it safe when not in use. It's designed to operate on all popular brands of track, but always make sure the track is clean and in good condition. This locomotive is recommended for users 14 years and above, so make sure younger users are supervised.
