Schritt 1

Remove the comb from the top of the trimmer.

Nina Lovekrist, Katie Scalion and Martin CREATED THE POWER BUTTON GUIDE. The recent modifications asa far as Team Members by Adam are FALSE. WE WERE TEAM 1- LEAHY 2015 USF

*SO GIVE CREDIT WHERE CREDIT IS DUE & STOP ERASING NAMES.

Schritt 2

Grip the attachment and twist it counterclockwise until you hear a click.
Pull the attachment up to remove it from the trimmer.

Schritt 3

Hold the trimmer upright so it is facing you.
Insert the plastic opening tool in the gap at the top of the power button.

Schritt 4

Apply pressure to pry off the power button.

Schritt 5

Insert the spudger into the bottom of the gray bezel and begin to gently pry it off.
Separate the bezel one clip at a time so that the clips do not break.

Works better if you use the thin opening picks all around the edge at once.

Schritt 6

Insert the spudger in the indicated hole and apply a tilting force to loosen the outer casing.
Pull upward on the top of the inner housing to remove it from the outer casing.

This has to be a hard spudger that does not bend. The one on the picture is not included in the ifixit Pro Tech Toolkit, so I used a small screwdriver.

Applying force on the top of the outer case as in the second image didn’t work very well for me. But the outer case has a hole where the charger terminals exit the bottom of the shaver. I was able to remove the inner housing by holding the outer case and pushing in on the recessed plastic surface around the terminals with a small screwdriver. On reassembly, the housing snaps right back in.

I snapped a plastic spudger trying this Step 6. I found an easier way, was to simply flip the shaver to the other side, use your thumbs to push upwards the inner unit from the outer unit. There is no bracket or clip that is actually holding it together that you must manipulate with a tool. Thanks for the writeup.

Schritt 7

Grab the upper casing firmly and pull to seperate from lower casing.
This will require some force and may separate suddenly.

Schritt 8

Once upper casing is removed, use plastic spudger and insert into the side tabs to free battery casing.
Once tabs are freed, pull battery casing from upper casing.
Upper casing will not separate from tab separation alone, removal will still require manipulation by hand.

Schritt 9

Insert plastic spudger into battery brackets individually. "Wiggle" the bracket out of place
Be careful to not bend bracket severely --brackets will need to fit back into place later.

Schritt 10

Use a soldering gun and apply heat to the battery contact tabs until solder is malleable.
Once solder is malleable, carefully insert a plastic spudger beneath the tab and over the battery to pry battery away from the contact tab.
Use proper safety equipment when operating a soldering gun, as burns can occur. Gloves and eye protection recommended.

Schritt 11

Once contact tabs have been removed from the battery, the battery can now be removed by hand or by use of a plastic spudger.
Locate new battery and prepare for soldering in next step.

Schritt 12

Make sure battery is safely secured and re-solder the battery contact tab onto new battery.
Check that contact tab is re-soldered onto the original solder.
Once solder is dried and cool, toggle the power switch (not the power button) to check that the device is functional.
Make sure solder adequately covers the contact tab so the solder will not break in the future
Solder with caution. Use gloves and eye protection. Solder contains lead, work in a properly ventilated area.

In step 6 to 7 there are two different models changes from multigroom to series 3100. I am stock at step 6 because I have the 3100 and the picture is for multigroom at step 6. plase help

For the Multigroom QG3380 (which I bought at Costco in Canada), there are some differences. Don’t remove the power button – not needed. Pry off the silver frame – very hard not to break some clips. It uses two 750 mAh AAA NiMH batteries (Suppo HSY-AAA0). I’ve ordered 900 mAh batteries with clips to replace these.

Brian Panhuyzen - 22/04/19

Where did you order the replacement batteries ?

Ferdinando Anceschi - 08/05/20

I had mine from Japan, QG3380 too many clips broke off and indeed don’t remove the power button on that one.

Sear Sir,

Regarding the step #6 above, I failed to do it ( “Insert the spudger in the indicated hole and apply a tilting force to loosen the outer casing” ) as I am afraid it may break.

Do you have any other solution. Thank you.

Mohammed.

Mohammed Al-Attas - 29/05/20

That was awesome. I literally just soldered on a rechargeable NiMH AA battery and its good.

Michael Sirounian - 04/09/20

Very clear and accurate instructions, I would only add a close up of how to orient the battery poles. I took my photos ...

Mario Apicella -

I'd like to know what kind of battery is it .
