Charging the trimmer
 Turn the trimmer off. Wipe off any water droplets on the appliance socket.
1.  Place the trimmer on the AC adaptor.
2.  Plug in the AC adaptor into a 
household outlet.
 Check that the charge indicator lamp glows. Charging is completed after approx. 15 hours.
3.  Disconnect the AC adaptor after 
charging is completed.
 The charge indicator lamp continues to   
glow after charging is complete. There is no   
indication to show that 
“charging is complete”.  Charging the battery for more than 15 hours   
will not affect battery performance.
 Note
You cannot operate the trimmer while charging.
  When charging the trimmer for the first time or when it has not 
been in use for more than 6 months, the charge indicator lamp 
may not glow for a few minutes, or the operating time may 
shorten. Please charge it for more than 23 hours in such cases.
 Recommended ambient temperature for charging is   
0 °C - 35 °C (32 °F - 95 °F). Battery performance may 
decrease outside of the recommended temperature.
  A full charge supplies enough power for approximately   
30 minutes of use.
  You can charge the battery before it is completely 
discharged. However, it is recommended to charge when the 
battery is completely discharged. The battery life depends 
strongly on factors such as how it is used and stored.
 If there is crackling noise on radios or other devices while 
charging, charge the clipper using a different household outlet.

 When trimming a short beard, it is effective to increase the 
number of trimming times in order to keep the beard uniform 
at the desirable length.
 It can also be used without the comb attachment.   
(Trimming height: approx. 0.5 mm (1/64˝  ))
 Actual hair length will be a little longer than the height you set.
Using the trimmer
 Make sure there is no damage to the blade. The appliance may not operate in an ambient temperature 
lower than approximately 0 °C (32 °F).
Dry trimming
 Trimming with the comb attachment Do not use when the beard is wet.   
A wet beard may stick to the skin or bunch up, making it 
difficult to trim.
1.  Mount the comb attachment and adjust the dial. 
(See this page.)
2.  Slide the power switch to the “
 ” 
position to turn on the trimmer.
3.  Hold the trimmer with the power 
switch facing upward, and cut the 
beard by moving the trimmer back 
against the flow of the beard.
 Hair trimmings may collect inside the 
attachment when a large volume of 
beard is cut, so discard hair trimmings 
after each use.
