Using the Makita 417766-9 Tool Cuff Adapter is easy. First, make sure your 1 - inch hose is clean and free of any debris. Then, simply thread the adapter onto the hose. It should go on quickly and smoothly. When using the dust extraction system, ensure that the adapter is tightly connected to prevent any air or dust leakage. As for maintenance, periodically check the adapter for any signs of wear or damage. If it gets dirty, you can use a mild detergent and a soft cloth to clean it. Store it in a dry place when not in use to extend its lifespan.
