Stop using fan and recharge the battery cartridge when
you notice less power.
Do not recharge a fully charged battery cartridge.
Charge the battery cartridge with room temperature at
10 °C - 40 °C (50 °F - 104 °F).
Let a hot battery cartridge cool down before recharging it.
Charge the battery cartridge once in every six months if
you do not use it for a long period of time.
Assembly (Fig. 2, 3, 4)
Fit the band (5) on the helmet. Notice that the blow-hole
(6) comes below the helmet.
Adjust the length of the band by using the band clip (7).
Hang the battery holder by using the belt hook (8) to your
trousers belt or else.
Adjust the length of the cord (9) appropriately by using
the cord clip (10). Make sure the cord is not too loose.
Using adapter (Fig. 5, 6)
In case the brim of the helmet is too thick to attach the
fan stably, use the adapter (11) which is included in the
package. Attach the adapter to the fan, and then fasten
the fan as the ridge (12) of the adapter is fixed to the
bottom of the helmet.

on the battery holder. Each time you press the switch, the
mode changes in an order of normal mode, high mode,
and stop.
You can adjust the direction of blow by moving the flap
(14). Move the flap upwards to send blow to your head,
and downwards to send blow to your neck.


Use a dry cloth to wipe the dirt off the fan.
Never use gasoline, benzine, thinner, alcohol or the like.
Discoloration, deformation or cracks may result.
To maintain product SAFETY and RELIABILITY, repairs,
maintenance, or adjustment should be performed by
