How to keep a comfortable sharpness 

After use (especially shaving with soap), make sure to perform maintenance. Make sure to wash 

  the foil-cutter assembly with water.
  Accumulation of beard clippings will cause deterioration in sharpness or scattering of beard clippings.
  For the main body and trimming blade, the cleaning brush can also be used.
  Do not clean the foil-cutter assembly with the brush because doing so will cause deformation 
  of the cutter or breakage of the foil.
  After washing with water, apply the included shaver oil to the foil.
 

Smoothens rotation. 

Prevents reduction in operating times.

Keeps sharpness.   

Prevents blade heat generation.

Prevents blade wear.

Cleaning with water

The foil-cutter assembly can be washed with water.

1.  Turn "OFF" the switch to remove the cap and head holder.

(Fig.17)

Press the head holder removal button (1) to remove the head holder in the arrow (2) direction

.

2.  Turn "ON" the switch and pour water or lukewarm water between the foil assembly and main body 
 

for approximately 10 seconds to wash the foil and cutter  assembly.

(Fig.18)

Remove the holder while pressing the head holder removal button. 

Maintenance

Never wash the power adaptor and LED light dryer with water. Also, never soak 
them in water or splash water on them. (Cause of electric shocks and short circuits)
Be sure to disconnect the power adaptor from the outlet and main body for maintenance.
(Cause of electric shocks or injury) 

Never push the blades strongly. (Cause of damage to skin especially lips or damage to the shaver.)

Do not wash with water when using the shaver with AC. (Cause of short circuits)

Do not clean the foil-cutter assembly with the cleaning brush.
(Cause of deformation of the cutter or breakage of the foil)

Purchase optionally available shaver cleaner after the attached shaver oil is used up.

Turn “ON” the switch.

3.  Turn "OFF" the switch and store the trimming blade after operation. (Fig.16)
 

Caution

Never place fingers on the upper side of the trimming knob.

(The trimming blade will contact fingers at the time of storing.)

If the trimming knob is pushed downward with the trimming blade contacting fingers, storage will 

be impossible due to the disconnected lever.

Recommended

If the trimming blade cannot be stored, move the trimming knob upward and downward 

once or twice to restore it without forcibly pushing it in.

Advice
If buildup is severe or difficult to remove, wash with water, apply a small amount of kitchen detergent 
(neutral) to the foil, turn "ON" the switch, and evenly foam the entire surface of the blade for 
approximately 20 seconds. Then, wash the shaver once again to remove buildup. (Fig.19)
  
  If buildup still cannot be removed, remove the foil-cutter assembly, soak the shaver in water or 
  lukewarm water containing a small amount of kitchen detergent (neutral) for approximately eight hours, 
  then wash it with water to remove buildup. (Fig.20) 
  Please refer to "How to replace the foil-cutter assembly"  to detach or attach the foil-cutter assembly.   
Never use bathroom or toilet detergents, etc.
Caution
 

Never turn "ON" the switch without pouring water on the blade and with the head holder 

removed.  (Cause of scattering of hair clippings)

Never use hot water.  (Cause of deformation and failure of the shaver)

Never soak the main body in water. (Cause of failure of the shaver)

Foam for approximately 20 seconds.
