D.D.Deluxe
Yes you take the whole top piece off. The lense covering the light bulb is part of the top, although you can remove it once the top is off. This cover your removing doesn't use screws to hold it on, you have to insert a flat blade screwdriver into the front sides and rear sides and pry it off the bottom chassis.
You need to flip the machine over to get your screwdriver where you need to pry the cover off. If it hangs up and won't come off, check for a possible screw about where the handle release peddle is. Replacing the cover is a snap,pun intended.
