Put grease on the bolt threads and under the bolt head. Place the clamp around the bottom of your pro scooter bar. Line up with slit in bar. Make sure slit is AT LEAST as long as clamp height. Slide the bar over the fork steerer tube till it hits the top of the headset. Line up the bar with the pro scooter fork and front wheel. Tighten the bolts with a 5mm allen wrench. Switch between bolts while tightening to ensure even clamping and prevent stripping the threads. If you use ICS or HIC compression, tighten the compression before tightening the bolts on the clamp.
