Using your Makita B - 60523 Impact GOLD #2 Phillips 2' Power Bits is easy. First, make sure your impact driver is turned off. Then, insert the bit into the chuck of the impact driver. The 1/4 - inch shank is designed to fit most standard impact drivers. Once it's securely in place, you're ready to start your project. Whether you're building a deck, framing a wall, or installing a plywood subfloor, these bits are up to the task. When using the bits, apply a steady pressure and let the impact driver do the work. Don't force the bit too hard, as the Xtreme Torsion Technology is designed to handle the load. As for maintenance, after each use, wipe the bits clean with a dry cloth to remove any debris. Store them in a dry place to prevent rusting. If you notice any signs of wear or damage, like a worn - out tip or bent shank, it's time to replace the bit. That way, you can keep getting the best performance from your Makita Impact GOLD bits.
