Craftsman 21833 Operation Manual - Page 13

PLOUGHING Performed with rip fence, is grooving with grain long way of workpiece. Use proper hold downs and feed devices. RABBETING Performed with either miter gauge or rip fence. Rabbeting is known as cutting out a section of the corner of a piece of material, across an end or along an edge. To make a rabbet requires cuts which do not go all the way through the material. Therefore, blade guard must be removed. Install blade guard immediately upon completion of rabbeting operation. Rabbet cuts can also be made using dado head. DADOING Performed with either miter gauge or rip fence. Dadoing is done with a set of blades (dado set) rather than standard saw blades. The dado set is used to groove wood similar to ploughing and rabbeting. However, the dado set allows operator to remove more material in one pass. The operator, with a dado set, can vary width of cut up to _6". Instructions for operating dado set are contained in owner's manual furnished with dado set. Dadoing requires cuts which do not go all the way through material. Therefore, blade guard must be removed. Dado sets have different characteristics than saw blades. As a result, saw must be fitted with special parts that are furnished with saw (Dado Insert, Part No. 31158.OO). When using a dado set, the following parts must be substituted dado table insert (not included). IMPORTANT: Always use correct insert. When using the dado set, use caution. Use featherboards and push sticks as applicable. WARNING: Always immediately replace the standard blade, blade guard and blade insert when you are finished dadoing. CUTTING OVERSIZED WORKPIECES When cutting long workpieces or large panels, always support workpiece that is not on table. Use adjustable roller stand or make simple support by clamping a piece of plywood to saw horse. Add facings to miter gauge or rip fence as needed. IMPORTANT: Do not allow facings to interfere with operation of blade guard. DUST COLLECTING o Saw is fitted with a 4" male exhaust port. o Before starting saw, see that all adjustments are properly made and guards in place. With power disconnected, turn pulley by hand to make sure everything is correct before connecting power and starting saw. BLADE SELECTION Blade selection is based on type of material being cut and how it will be cut. There are three general types of saw blades: rip saw blades cut with grain of wood, cut-off saw blades cut across grain, and combination saw blades cut with grain, across grain and any angle to grain. Blades vary in many aspects. When selecting a blade, the fo!lowing blade characteristics should match up with operation to be performed and type of material to be cut: type of steel; quality of steel; tooth style; tooth set; carbide tipped; grind; number of teeth and size. MPORTANT: Your saw is only as accurate and efficient as blade or cutting tool used. First, be certain to use the appropriate type of cutting tool for the operation to be performed. Second, it is strongly recommended that high-quality blades and cutting tools be used. Be certain blades and cutting tools are kept sharp and in good working order. Check blades periodically and replace or sharpen if necessary. WARNING: Do not attempt under any circumstances, to service, repair, dismantle, or disassemble any mechanical or electrical components without physically disconnecting all power sources. CLEANING Clean off any preservative on bright (machined) parts with appropriate solvent (mineral spirits). Avoid getting cleaning fluid on any rubber parts as they tend to deteriorate rubber. • Use soap and soft water on rubber and plastic parts. • After cleaning, lubricate unpainted surfaces with a light application of medium consistency machine oil. This lubrication should be repeated at least once every six months. NOTE: Instead of oil, a good quality paste wax can be applied to rip fence and table surface. Paste wax will enhance movement of workpieces. In addition to providing lubrication, paste wax will help prevent rusting. • Keep your machine and your workshop clean. Do not allow sawdust to accumulate on saw or inside cabinet. Frequently vacuum or blow out any sawdust that may accumulate within cabinet. • Be certain motor and internal mechanisms are clean and are frequently vacuumed or blown free of any dirt. LUBRICATION All bearingson the arbor are shieldedbali bearings. These bearings are permanentlylubricated at the factory. ° As needed, clean the grease off the rackand worm gears of height and tilt mechanism.Lubricaterackand gears with a mediumviscositymachine oil. • Be sure to lubricatetrunnionways and all bushings. • Occasionally oil all otherbearing points, including blade guard assembly, miter gauge and rip fence. SERVICE * Replace beltsand worn parts as needed. If powercords are worn, cut, or damagedin any way,have them replaced immediately. ° Make sure teeth of anti-kickbackpawls are alwayssharp. . Sharpen dull teeth usinga few lightstrokes of a smooth cut flat file. 13
