To get at the switch area for lead renewal:
1. Remove screw at back and bottom of handle (recessed down in handle) and the handle will slide backwords off the main body. Note it is stiff and does not slide off easily.
The handle holds in place the clip action of the switch area cover.
2. Remove the 2 screws on the switch cover and using the finger lifting slot at the front lift the front of the cover so the cover hinges up and back which will release the plastic clip extension at the back (that clip is the bit covered by the handle so it will not release the cover with only the screws out and the handle in place).
