Overhaul
(P.S.) Use a soft cloth to remove dusts when cleaning. Do not blow off dust with equipment such as air
blowers. Wind pressure will cause the dusts to enter the inside of the fan and the blades rotate at a speed
exceeding the rated speed, which may cause the fan to malfunction or affect its life. Only use the vacuum
cleaner on the blade section. Do not vacuum the rotating part or the main body, which can cause the fan to
malfunction or reduction of the fan’s service life.
