Using for the first time: Unscrew the base of the unit in an anti-clockwise direction and remove. Remove and dispose of both the red insulator tab and the plastic ring. Replace the base of the unit and screw in a clockwise direction until secure. Follow the directions for regular usage. Regular usage: Remove the protective roller cover before use. Ensure that the roller head is securely inserted into the unit. Do not use without the roller head attached. Turn on by twisting the silver ring to the left and gently glide the rollerhead over heard skin and the dead skin will gradually exfoliate. Use only on dry skin. Do not press too hard, or the unit will stop. Turn off and check if you have achieved the softness you desire. If not, turn on and repeat until the level of smoothness is obtained. Turn off by twisting the silver ring to the right. Wipe or rinse feet to remove excess dead skin particles. Thoroughly dry feet. Apply moisturiser and massage into your fabulous smooth feet.
