It could be that the battery of your nose trimmer has run out. To confirm this, perform the following actions:

1.  Switch off your nose trimmer.
2.  Detach the trimming head and switch on the trimmer.
3.  Is the motor running and pin rotating? If no, the battery of the trimmer has run out. 
4.  Reattach the head to the trimmer and recharge the nose trimmer. 

While charging your groomer make sure you use the original charger which comes with your device. For further charging instructions please refer to the user manual. 

Trimmers with disposable batteries
If you own a nose trimmer which runs on disposable AA batteries, it is possible that it is time to replace these. To solve this issue simply replace the battery with a new one. When replacing the battery, make sure that the + and - poles of the battery point in the right direction. 

If you have confirmed that your nose trimmer is charged, then it may not be working because it is dirty. Follow our cleaning advice below.

1. Switch on your nose trimmer and rinse the trimming head of the nose trimmer with luke-warm water. Then switch off the appliance again.
2. If rinsing the trimming head under the tap is not sufficient, immerse the trimming head in a glass with warm water for a few minutes. Do not put the handle of the trimmer in the water, as this can damage its internal machinery.
3. If this not helps, detach the nose trimmer attachment and soak this part separately in water for 8 hours.
4. Carefully shake off excess water and let the trimmer air dry. 

For best results, clean your Philips Nose Trimmer after each use and lubricate the trimming head with a drop of sewing machine oil every six months.
