Use a firm stool or ladder when cleaning or maintaining the product.
Do not wipe the controller operation panel with benzine, thinner, chemical dust cloths, etc. The panel may get discolored or the coating may peel off.
If the product is very dirty, soak a cloth in water-diluted neutral detergent, squeeze it well and wipe the panel clean. Then wipe it dry it with another dry cloth.
Do not touch the metal parts of the product when removing the air filter. They are very sharp.
Contact the dealer for repair or maintenance.
