PROTECT YOUR FURNITURE
This product is equipped with non-skid rubber 'feet' to prevent the product from moving when you operate the
controls. These 'feet' are made from non-migrating rubber material specially formulated to avoid leaving any
marks or stains on your furniture. However certain types of oil based furniture polishes, wood preservatives, or
cleaning sprays may cause the rubber 'feet' to soften, and leave marks or a rubber residue on the furniture. To
prevent any damage to your furniture we strongly recommend that you purchase small self-adhesive felt pads,
available at hardware stores and home improvement centers everywhere, and apply these pads to the bottom
of the rubber 'feet' before you place the product on fine wooden furniture.
