Cleaning and Maintenance
Cleaning synthetic leather and plastic parts
Wipe the leather with a soft, dry cloth.
Do not use chemicals such as thinner, gasoline, alcohol, etc. to clean the unit. When using commercially available leather care products (rags), please follow
the instructions for use. If synthetic leather is particularly dirty, wipe it in the following way. Immerse a soft cloth in water or hot water containing 3% to 5% neutral
detergent, then wring it out thoroughly. Use the above soft cloth to wipe the leather surface. Wipe off the cleaning solution with a cloth soaked in clean water and thoroughly
wrung out. Wipe with a wrung soft cloth. Let it air dry naturally. When it is difficult to remove stains, please immerse commercially available
melamine foam in neutral detergent, and then wipe the machine with it. Do not use a hair dryer to dry the surface. Be careful when wiping the machine with denim and colored fabrics, as the color
of the fabric will stain the surface of the synthetic leather. Do not keep these parts in contact with plastic for a long time, as this will cause
discoloration. Synthetic leather may be discolored, so when using hair dye, please cover the
touched part with a towel.
