A complete shaving unit consists of:

• 3 cutters
• 1 shaving-head holder (top part of the shaving unit) 
• 1 retaining frame (green)
• 1 bottom part of the shaving unit

Note: The shaving guards of this shaver cannot be removed. If they are accidentally removed from the shaving- head holder and you cannot replace them, please phone the Consumer Care Center in your country or take the appliance to your dealer.

1. Place the shaving-head holder in front of you, with the shaving guards facing down. [picture 2]
2. Place the three cutters back into the shaving guards with the cutter legs pointing downwards. [picture 3]

3. Place the green retaining frame back onto the shaving-head holder.

• Make sure you place the retaining frame in the correct way: 
  • The small arrows should face up [picture 4]
  • The arrow head on the shaving-head holder should be pointing to the bottom arrow on the retaining frame [picture 5]

4. Slide the retaining frame back into position ('click'). [picture 6]
