Introduction: Sonicare FlexCare - Tighten Metal Shaft
This process will demonstrate how to remove the internal assembly and tighten the metal shaft on a Sonicare FlexCare toothbrush.
To complete this, you will need 5-10 minutes and the following:
Standard flat head screwdriver
#0 Phillips screw driver
A little common sense
Step 1: Disassembly
Remove brush head
Using a standard flathead screwdriver
Gently twist the bottom plug until it releases
Gently remove the plug
Please note the tabs holding the plug in place are soft plastic and look like they will easily break.
Holding the body, push down on the metal shaft. Because of the seal it will take a little effort so I used side of the handle on my screw driver to break the seal and push it down.
Pull the internal assembly out
Step 2: Tighten Metal Shaft
Using a #0 Phillips screwdriver, tighten the screw that holds the metal shaft
Step 3: Battery
Though this is not a step to replace the Li-Ion battery, I thought I would post a photo.
It appears that the battery is glued in place, but I think others have posted instructions on how to remove it.
Step 4: Reassembly
Just the reverse of step 1
Push the internal assembly back into the body until rubber seal is flush with the top of the body
Push the plug straight in until it snaps into place
Attach brush head
Step 5: Test Your Work
It should be pretty obvious, but try brushing your teeth!
If you really need brushing instructions you probably should not be using a Sonicare

While this instruction is useful, I also found the instructions in https://www.ifixit.com/Guide/How+to+fix+loss+of+po... is more suitable for my problem. Please read that.
To access the two screws, no need to bend it as JamesD280 described, just hold the bright red coil part with one hand, and hold around the battery top part, pull (as if you are pulling the cap out of your pen) with a slight wiggle, they will come apart, then you can access the second screw. Snap them back after you are done.
I also found you do not have to set the bright red coil too far away down. When the two screws come loose, the red coil will snap to the top part, leaving no gaps in between, because they are magnets. Better insert a small flat head screwdriver as JamesD280 showed in the photo, before loosen both screws.
Good luck with your toothbrush!
