Hopefully you discovered it's not difficult to take the shaver apart--at least if it's like mine.

Two screws on the back hold it together--one visible, one under the flip trimmer. They have odd slots but can be undone with a small slot screwdriver, though I think the proper way is with a torxx.

Once you undo the screws, take off the metal clips that hold in the batteries and serve as the screw holes. The batteries can be flipped up carefully (so as not to break the copper wires to the motor).

If your problem is like mine, you'll see a clear plastic piece that has dislodged from under the rubber push switch. Place the round end so that it lays in the rubber dome and contacts the switch.

You can flip the batteries back down in their proper position at this point and test to see if the plastic part is seated properly.

Then simply put the metal clips back and replace the screws. Amazingly simple. Hope that helps.

Exactly the same as the failure on mine and exactly the same strip down method I used. On replacement I used a touch of glue between the plastic piece and the rubber dome, I hope this keeps it in place for the future.

Change battery


The batteries need replaced. You will find the correct batteries at shaveroutlet.com at the link below

http://shaveroutlet.com/shaver-replacement-parts/batteries/philips-norelco/shaver-battery-pack-for-most-norelco-more-p-278.html

To open the shaver you will need to remove the back cover by removing the two screws. You may need to slide the trimmer up to reveal second screw. Inside, you will need to remove the metal clip that is in the way.

Use the tutorial video at the link below for information on changing the batteries

Hi the shaver isnt cutting as good as it should do i need new cutting folis or new cuttting blades? which eather where can i get them from? Many thanks Donna


Philips suggests that the heads be changed every 12 months. If they are 12 months olor older and no longer cut well, they probably need replacing. You will fin replacements at shaveroutlet.com. See link below

My Philishave HQ5620 charger is kicking out 5.8V(ac), but my shaver fails to charge up. Any ideas why?


After a couple of years the battery may no longer hold a charge and need replacement.

My shaver switch giving me problem it doesn't switch on when pressing once when switch on it does not switch off at all until charge of the battery drains off.


I have the same problem with the switch after many years of usage and no replacements on anything.
I took it apart and put the clear plastic plunger back in the rubber push button but it doesn't seem to contact anything when I press it.
I don't think I lost a part, but somethin seems to be missing???
Any ideas?
