Using these HO Scale Kadee trucks is easy. First, you can mount them on your model using a #2 or 2 - 56 screw. When handling them, be gentle as they have small and delicate parts. For maintenance, keep them clean from dust and debris. You can use a soft brush to clean the wheels and frames. Store them in a dry place to prevent rusting. If you notice any parts getting loose, check the screws and tighten them carefully. These trucks are designed for smooth operation, so make sure your model railroad tracks are in good condition for the best performance.
