The BioStep has been designed to provide many years of dependable use. To help ensure this
product performs to the maximum specifications, and to increase the life of the product, please
note the following general cleaning instructions and maintenance procedures.
1. As required, clean all exterior surfaces, upholstery and restraining straps. Specialized vinyl
cleaners or protectants are recommended for upholstery and cushions. Otherwise, use a solu-
tion of warm water and mild detergent.
2. As needed, wipe the display using a soft rag dampened with alcohol.
3. Lubricate the linkage bearings with lithium grease or oil as needed. Periodic lubrication of the
bearings will prevent them from becoming noisy. Lubricate the linkage bearings once a year
or every six months for heavy usage.
SUGGESTED METHODS FOR LUBRICATING LINKAGE BEARINGS
1. With the BioStep resting on its side, apply oil or grease to the outer race of the spherical bear-
ings. Allow the BioStep to set for several minutes while the oil wicks to the opposite side. Lay
the BioStep on the opposite side and repeat. Return the BioStep to its upright position.
2. Axially rotate the linkage in question to expose the maximum amount of ball bearings and
race. Place the extension tube from the spray can of lithium grease between the linkage com-
ponents and spray lightly. Repeat this for all 12 spherical bearings. Move the linkages in both
directions to ensure the grease wicks to the steel ball of the bearing.
3. Remove the set screws from within the lubrication port located on the ends of the cast links.
Insert the extension tube from the spray can of lithium grease into the port. While holding a
rag over the grease port to prevent spray back, spray lubrication into the bearings. The set
screws do not need to be replaced.
