Step 3:  Attach the down tube bracket

Wrap the down tube bracket around the down tube with the holes for the screw facing down and the nub that attaches to the chain guard facing the chain ring.  Put the nut and screw in place, but keep the bracket loose so it can be adjusted later.

Step 6: Position the chain guard and tighten

Move the brackets and chain guard until the chainguard is properly positioned on the bike.  The chainguard should sit close to the chainwheel.  Make sure that the chainguard is positioned so that it does not interfere with pedal, crank and/or chain operation.  Tighten the bracket screws.
