Using your Bosch 8-Piece Impact-Resistant Square 2 Power Bit Set is easy. First, open the case using the secure latch. The tilt-in/tilt-out mechanism allows you to quickly access the bit you need. Simply snap the bit out of the clip and insert it into your impact driver. When you're done, snap the bit back into the clip and close the case. Make sure to use the right bit for the job. The high-visibility markings on the bits will help you choose the correct one. Avoid using the bits with excessive force, as this can damage them. After each use, wipe the bits clean with a dry cloth. If they get dirty, you can use a mild cleaner. Store the set in a dry place to prevent rusting. The rubber bumpers on the case protect it from damage, but still handle it with care to keep it in good condition.
