Philishave QT4040 stops during use

I have a Philishave QT4040. Even when the battery is fully charged, sometimes the unit stops while I am trimming my beard.

The only way I can get it running is to hit the unit a number of times with my palm, or remove the cutting head and manually spin the chrome rotor (which fits into the cutting head).

Why am I having this problem?

    I am having the same problem with my qt4040. It has now reached the point where I am no longer able to get it running by giving it a good whack. It is probably the electrical connection between battery and motor that is failing. I am currently trying to figure out how to take the shaver apart and resolve the issue.

Apparently you need to change the heads within two weeks after the red LED first starts to flash, otherwise the memory chip inside needs resetting. This also poses a further question. How does the unit know the heads have been changed or not ?

SOURCE: Remington HC600 hair clipper stopped clipping

To all of you: adjusting the screws won't help, unless you screwed something up yourself, of course LOL The same problem bothered me a few years, and an hour ago I found out it could easily be a single hair stuck between the blades, thus separating them a bit. Get rid of it and the trimmer will probably work again. It can even get out spontaneously, which happened to me and kept me wondering what was going on.
P.S. DON'T lubricate unless you are required to (check your manual) The model I have (HC210c) does't need lubrication, I guess yours is similar to it. And remember that NOT every oily substance is a machine lubricant.

SOURCE: I have a Philishave bought

Based on the information you provided, it sounds like it is a Quadra Series shaver but it is not possible to tell the specific model number. The model number should be written on the shaver somewhere. has a video that can help you find the model number. See link below

SOURCE: I have had a Braun

The internal slider which turns the shaver on/off is broken:--- After you pry out the blue button. In the oval hole where the blue button was fitted you will see a thin metallic part (semi-circular shapes on each side); pull it out through the hole and the switch will be functional.But if its not turning off then its broken. When the shaver is turned on with the main On/Off slider, a spring moves a small slider inside to make contact with two areas on the circuit board. The small internal slider is broke in half, so when the main On/Off slider is moved to the off position, only half of the internal slider moves. The other half with the electrical contacts is staying in place on the circuit board, allowing the shaver to still operate.But if its broken then you will have to re-solder this metallic part and it should contact the circuit board to turn on/off.If you are not able to solder it,just get the take the metallic part and shaver to local electronic appliance repair center or at any local tv repair center.They deal will soldering jobs.Just get that metallic part to its exact position.So it functions properly. ---------------- This should help.Thanks.Helpmech.

It is impossible for me to say for sure without actually looking at it but the problem is, most likely, the battery. Changing it will probably fix the problem.
Take a look at the circuit boeard for corrosion or burnt spots. If you see neither of these, I would say that there is a 98% chance that only the battery needs changed

I am looking for a manual for a Philishave Model 805 electric shaver. How do you know when the shaver is fully charged. The green light is always on solid from start to finish

I don't believe that there is an on-line model for this model as it is an older model. The charge time for this model is 16 hours. There is no indicator to tell you when it is done.

I can't get my Philishave Coolskin to accept a charge. Pretty sure that the charger is working as I was getting the red charge light but didn't get the green bar indicators as it charged. Any ideas

Most likely, the battery needs to be replaced. The symptom you describe would suggest this.
You can purchase a replacement battery pack for model HQ6740 at See link below

To change batteries you will need to remove the lotion packet cover on the back and then remove all of the screws on the back to remove the back of the case.
For easier replacement, it is sometimes suggested that you use a modified installation technique. This is to break the tabs off of the old batteries rather than unsoldering them from the circuit board. This allows the old batteries to be removed but leaves the tabs attached to the circuit board. You can then solder the tabs from the new batteries to the old existing tabs

Charged for approx. 6 hours then wouldn't work

I copied this from the Philips website... this took me FOREVER to find! Their site isn't the easiest to find products on...

"Insert the small plug into the shaver and put the powerplug in the wall socket. When you charge the appliance for the first time or after a long period of disuse, let the shaver charge for at least 16 hours. Remove the powerplug from the socket and the small plug from the shaver as soon as the batteries have been fully charged. Ignore the charge indicator when you charge the batteries for the first time. The batteries are completely new and need to be charged longer than the time indicated by the charge indicator to ensure that the back-up capacity is fully charged as well."

I hope this helps. Please remember to rate my help! I would greatly appreciate it!
