Using the Bosch SDMS44 is a breeze. First, open the case using the secure latch. Thanks to the tilt - in/tilt - out design, you can easily reach for the bit you need. Select the appropriate bit based on your project, like choosing a Phillips bit for Phillips screws. When using the bit with an impact driver, make sure the driver is set to the right torque level. The Xtended Torsion Zone on the bits will handle the high - torque, but don't use excessive force. As for maintenance, keep the bits clean after each use. You can use a dry cloth to wipe off any debris. Store the case in a dry place to prevent rusting. Also, the rubber bumpers on the case protect it from impacts, so try not to remove them. This way, your Bosch SDMS44 will last you a long time and keep performing at its best.
