Adjust the height of the spindle mount so that the distance from the bottom of the spindle mount to the top surface of the styrofoam is 110mm / 4.5 inches.
Slide the ASA printed sleeve up so that it touches the bottom of the spindle mount. Hold in place or use some tape to keep it temporarily fixed. Make sure the knotch in the top center is facing the front. The 2 bottom safety pins should be visible on the sides. The knotch will receive the pin from the bracket in the next step.
Attach the included bracket to the spindle mount using the (4) m5 x 10 screws. Tighten loosely until you know the pin fits into the slot.
Connect 4" hose to the adapter. Screw it left handed.
This is what I used
Pull the dust boot open and hook it on. Make sure the rubber band is on. This gives it the friction it needs.
