Using this table lamp is a breeze. First, complete the partial assembly by attaching the shade to the lamp base using the harp shade fitter. Plug in the 72-inch cord to a power source. Use the 3 - way switch to turn the lamp on and choose from different lighting levels. You can also adjust the brightness to your preference using the dimming feature. When it comes to maintenance, gently dust the lamp and the linen shade regularly with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials as they can damage the lamp's finish and the shade. This lamp is not for commercial use, so make sure to use it only in a residential setting.
