Figure 3 Shipping inventory 13 Model SB1027 Cleaning amp Protecting The unpainted surfaces are coated at the factory with a heavy duty rust preventative that prevents corrosion during shipment and storage The benefit of this rust preventative is that it works very well The downside is that it can be time consuming to thoroughly remove Be patient and do a careful job when cleaning and removing the rust preventative The time you spend doing this will reward you with smooth sliding parts and a better appreciation for the proper care of the unpainted surfaces Although there are many ways to successfully remove the rust preventative we have cleaned thousands of machines and found the following process to be the best balance between efficiency and minimized exposure to toxic fumes or chemicals Before cleaning gather the following e Disposable rags e Cleaner degreaser certain citrus based degreasers work extremely well and they have non toxic fumes e Safety glasses amp disposable gloves Note Automotive degreasers mineral spirits or WDe40 can be used to remove rust preventative Before using these products though test them on an inconspicuous area of a painted area to make sure they will not damage it AWARNING Gasoline and petroleum products have low flash points and can explode or cause fire if used for cleaning Avoid using these products to remove rust preventative PREPARATION
