frame and rinse the inner blade/outer foil under running water or in a basin.
DO NOT USE BOILING WATER.
Next, close the outer foil frame and dry it gently. After the shaving head is dry, place the protective cap.
Replacing shaving head components
It is recommended that you replace the outer foil at least once every year and the inner blade at least once every two years to maintain your shaver’s cutting performance.
Replacing the outer foil
Press the outer foil frame release buttons to remove the outer foil frame.
Then, squeeze the front and the back side of the outer foil frame and lift up one of the two knobs on the outer foil.
Inserting the new outer foil
Slip the foil into the frame and guide the plastic edges onto the hooks in the outer foil frame until it clicks into the shaver.
Replacing the inner blade
Squeeze the outer foil frame release buttons and lift the outer foil frame upward to remove it. Remove the inner blade by grasping it firmly at both ends and pulling straight away from the shaver. To insert the new inner blade, hold the blade at both ends and press downward until it snaps into the shaver.
