harm the skin and damage clothing. If your skin or your eyes
make contact with the electrolyte, rinse immediately with clean
water and consult a doctor.

the filter subdrawer and pull it out before dismantling the right-hand
fan and replacing the rechargeable battery (see section entitled

3.5-6.5 mm) into the right-hand unlock fan opening.

your finger in the round opening on the underside at the
front and pulling downwards).
