Using this bracket is easy. First, measure the distance between the bolts on your stem to make sure it's between 23mm and 40mm. Then, choose whether you want to mount the light upright or inverted and select the appropriate set of bolts (top or bottom) on the bracket. Attach the bracket to the stem using the provided M5 bolts. If you're using a Six Pack OR Maxx D, remember to mount the light above the bars. As for maintenance, keep it clean and dry. Regularly check the bolts to ensure they're tight. Don't expose it to extreme temperatures or harsh chemicals.
