PROTECT YOUR FURNITURE
This system 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.
