Rubber or plastic products due to oxygen and sunlight to ultraviolet radiation in the air, easy to aging deterioration, to make rubber elasticity or break.

    Custody of rubber parts as possible, preferably coated with hot paraffin oil to the rubber surface, must be placed indoors to stand, remove the drive belt on the interior safekeeping; some removably easily deformed parts should be flat as long arbor or vertical suspended; in addition to remove parts such as tires, tubes and other kinds of input and dried, but not exposed to direct sunlight. Hangar hangar leaking and insufficiently ground to new renovation and repairs, window palpable be reinforced, preferably in series between the equipment locked with a chain.

    When keeping the best paper to rubber cover, the storage area to maintain ventilation, pay attention to prevent deformation. Like a spring, and a long belt holder and tires and other parts due to the long press or force some improper placement will produce plastic deformation, the following should be properly supported in the frame, so that the tires do not bear the load; to mechanically all pinch or pull the spring must be relaxed.

    When the first rubber custody to prevent extrusion. But also to prevent the aging of rubber products.
