10. help prevent a dip or gouge This allows the abrasive to work the wider width with less effort and to achieve better consistency of the finished surface Stock Feeding Angle Some pieces because of their dimensions will need to be fed into the machine at a 90 angle perpendicular to the drum However even a slight offset angle of the stock will provide for more effective stock removal The optimum feeding angle for stock removal is about 60 21 Angling the workpiece for stock removal provides other advantages such as less loading of certain areas of the drums due to glue lines or mineral streaks in the stock more even wear of abrasive strips potentially faster feed rates and lighter loads on the motor Note that to get the best final finish however the stock should be fed through the machine so it will be sanded in line with the grain of the wood on the final one or two passes Maintenance AWARNING Before doing maintenance on the machine disconnect it from the electrical supply by pulling out the plug or switching off the main switch Failure to comply may cause serious injury Keeping the Machine Clean For best results make cleaning the sander a regular shop procedure Allowing excess build up of dust and debris can adversely affect performance through the loading of the abrasives slippage on the conveyor table and or the accumulation of material inside the drums which can throw off the center of balanc

14. proper contact between the abrasive and the stock determines the depth of cut The depth of cut is controlled by the height adjustment handwheel It may take some experimentation to determine the proper depth of cut given the variables of abrasive grit type of wood and feed rate For best results use scrap wood to practice sanding and to develop skill and familiarity with the machine before doing finish work A combination of several variables will determine the proper depth of cut to use including the following 1 Abrasive type and grit size 2 Width of the piece being processed 3 Hardness of the piece 4 Feedrate of the conveyor belt Establishing Proper Drum Height A good rule of thumb when sanding with grits finer than 80 is to place the stock to be sanded under the drum and lower drum until it contacts the stock Drum should still rotate by hand Without changing drum height finish feeding the stock under the sander Start sanding drum and sand the stock at that same position AWARNING Do not start drum while in contact with stock For sanding with grits coarser than 80 you can raise the conveyor table slightly Always maintain control of stock Through practice you will learn the proper depth of cut considering the variables above Selecting SandSmart Feed Rates A faster feed rate allows faster sanding but fewer revolutions of the drum per inch of sanding A slower feed rate provides more rev
15. various grits JET offers abrasives in the ten different grits shown consult the stock numbers on page 28 to order The amount of stock to be removed is a major consideration when choosing the grit grade with which to begin Grits 24 36 50 and 60 are primarily designed for stock removal Grits 24 and 36 will remove the most material in one pass whether you are doing abrasive planing cleaning up glued panels or flattening stock Grits from 100 through 220 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 general premium quality abrasives will produce a better finish with a less noticeable scratch pattern NOTE 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 cleaning sticks following the manufacturer s directions When cleaning also brush the stick crumbs from the drum while it is still rotating In some cases build ups resulting from burns can also be removed with Plexiglas held on edge over the rotati
