Squeeze the faceplate from the sides as pictured below, and slip a #1 flathead screwdriver in the gap
created. Pry gently to release the faceplate.
Unplug the faceplate from the connector and set it aside.
SHIMMING
Prepare a tiny silicone shim. Flip the grinder so it is upright. Using your #1 Flathead screwdriver, gently
pry open the gap on the lever arm just enough to set the shim in the top. Then, remove the screwdriver
and use a paperclip to push the shim down and fully seat it in the crevice.
