Although safety is foremost when I work, steps 2 through 12 are not really necessary. Step 1 is important for sure but then all you need to do to before Step 13 is to remove the screw near the upper-left of the Starter Case holding the Front Hand Guard in place and pull the Guard up and away from the Starter Case.
