5. stock or the amount of stock to be removed Then progres sively work toward finer grits This means if you are using two different grits on your 55220 dual drum sander the coarser grit should always be placed on the front drum The amount of stock to be removed is a major consid eration when choosing the grit grade to start with Grits 36 and 60 are primarily designed for stock removal grits over 100 are primarily finishing grits designed to remove the scratch pattern from the previous grit used For best results never skip more than one grit grade when progressing through a sanding sequence For fine work such as furniture try not to skip any grit grades during the sanding process In general premium quality abrasives will produce a better finish with a less noticeable scratch pattern CAUTION Grits that are too fine can sometimes burnish the wood and leave a glossy surface which will not accept stains evenly This will vary by type of wood Oak for example is susceptible to burnishing because of its open pores Cleaning abrasive strips Regularly clean the abrasive strips on the drums with commercially available clean ing sticks following the manufacturer s directions When cleaning also brush the stick crumbs from the drum while it is still rotating A CAUTION Wear tight fitting clothes and eye protection during this procedure stay alert to prevent injury Cloth backed abrasives can be cleaned by soaking in paint
