B E Fig. 54 OPERATION OPERATIONAL CONTROLS AND ADJUSTMENTS A B A Fig. 55 Fig.
OVERLOAD PROTECTION A The motor supplied with your saw is equipped with a manual reset overload (A) Fig. 58. If the motor shuts off or fails to start due to overloading (cutting stock too fast, using a dull blade, using the saw beyond its capacity, etc.), or low voltage, move the ON/OFF switch to the “OFF” position, let the motor cool three to five minutes and push the reset button (A), which will reset the overload device. The motor can then be turned on again in the usual manner.
ASSEMBLING MITER GAUGE A B Place a flat washer (A) Fig. 62 on the threads of the miter gauge lock handle (B) and then thread the handle into the hole (C) in miter gauge bar. Insert washer (D) Fig. 64 into the miter gage slot (E) and slide miter gauge onto saw table. C MITER GAUGE OPERATION AND ADJUSTMENT Fig. 62 The miter gauge is equipped with adjustable index stops at 90, 75, 60, 45 and 30 degrees. To rotate the miter gauge, loosen lock knob (A) Fig.
ALIGNING MITER SLOTS TO BLADE The saw table has been aligned at the factory so the miter gauge slots are parallel to the saw blade. However, it is recommended to check the alignment before initial operation as follows: A DISCONNECT MACHINE FROM POWER SOURCE. 1. Place a combination square (A) Fig. 66, on the table with one edge of the square in the miter gauge slot, as shown, and adjust the square so the ruler just touches one of the teeth on the saw blade at the forward position, as shown in Fig. 66.
BACKLASH ADJUSTMENTS FOR BLADE RAISING AND BLADE TILTING MECHANISMS D If any play is detected in the blade raising or blade tilting mechanisms, the following adjustments should be made. DISCONNECT MACHINE FROM POWER SOURCE. NOTE: The machine has been turned upside down and the blade removed for clarity and safety. 1. Adjusting blade raising mechanism - Loosen locknut (A) Fig. 71, and turn eccentric sleeve (B) until all play is removed in mechanism, then tighten locknut (A). 2.

BLADE GUARD AND SPLITTER USE THE BLADE GUARD ASSEMBLY PROVIDED WITH DELTA SAWS, AS SHOWN IN FIG. S1 MUST BE USED FOR ALL THROUGH-SAWING OPERATIONS. The splitter prevents the kerf from closing and binding the blade, causing kickback. The anti-kickback pawls (A) Fig. S1 prevent the workpiece and cut-off piece from being thrown back at the operator. The plastic guard prevents dust and debris from being thrown at the operator. To use the guard properly: 1.
NEVER USE THE FENCE AS A CUT-OFF GAUGE WHEN CROSS-CUTTING. When cross-cutting a number of pieces to the same length, a block of wood (B), can be clamped to the fence and used as a cut-off gauge as shown in Fig. S4. The block (B) must be at least 3/4-inch thick to prevent the cut-off piece from binding between the blade and the fence during removal from the saw table. It is important that this block of wood always be positioned in front of the saw blade as shown.
RIPPING Ripping, as shown in Fig. S8, is cutting lengthwise through a board. The rip fence (A) is used to position and guide the work. One edge of the work rides against the rip fence while the flat side of the board rests on the table. A THE SAW BLADE GUARD MUST BE USED. ON DELTA SAWS, THE GUARD HAS ANTI-KICKBACK PAWLS TO PREVENT KICKBACK AND A SPLITTER TO PREVENT THE WOOD KERF FROM CLOSING AND BINDING THE BLADE. BE SURE TO REPLACE OR SHARPEN THE ANTI-KICKBACK DEVICES WHEN THE POINTS BECOME DULL. Fig.
NOTE: In Fig. S11, the guard and splitter have been removed for clarity. Guard and splitter should be used when ripping. 5. For longer pieces, use one or more pushsticks to avoid placing your hands between the fence and the blade. Always use care to avoid binding narrow strips between the anti-kickback pawls and the splitter.
NOTE: THE OUTSIDE ARBOR FLANGE CAN NOT BE USED WITH THE MOULDING CUTTERHEAD. TIGHTEN THE ARBOR NUT AGAINST THE CUTTERHEAD BODY. DO NOT LOSE THE OUTSIDE ARBOR FLANGE. IT WILL BE NEEDED WHEN REATTACHING A BLADE TO THE ARBOR. ALWAYS RETURN AND FASTEN THE BLADE GUARD AND SPLITTER ASSEMBLY TO ITS PROPER OPERATING POSITION FOR NORMAL THRU-SAWING OPERATIONS AS SHOWN IN FIG. 39. A B 1. A moulding cutterhead (A) Fig. S15 can be easily assembled to the saw arbor.
1. Dadoing is cutting a rabbet or wide groove into the work. Most dado head sets are made up of two outside saws and four or five inside cutters, (Fig. S17). Various combinations of saws and cutters are used to cut grooves from 1/8″ to 13/16″ for use in shelving, making joints, tenoning, grooving, etc. The cutters are heavily swaged and must be arranged so that the teeth do not hit each other during rotation. The heavy portion of the cutters should fall in the gullets of the outside saws, as shown in Fig.
CONSTRUCTING A FEATHERBOARD Fig. S23, illustrates dimensions for making a typical featherboard. The material which the featherboard is constructed of, should be a straight piece of wood that is free of knots and cracks. Featherboards are used to keep the work in contact with the fence and table, as shown in Fig. S24, and help prevent kickbacks. Clamp the featherboards to the fence and table so that the leading edge of the featherboards will support the workpiece until the cut is completed.
CONSTRUCTING A PUSH STICK Fig. S25 34 1/2" SQUARES CUT OFF HERE TO PUSH 1/2" WOOD CUT OFF HERE TO PUSH 1/4" WOOD NOTCH TO HELP PREVENT HAND FROM SLIPPING MAKE FROM 1/2" OR 3/4" WOOD OR THICKNESS LESS THAN WIDTH OF MATERIAL TO BE CUT PUSH STICK WHEN RIPPING WORK LESS THAN 6 INCHES WIDE, A PUSH STICK SHOULD BE USED TO COMPLETE THE FEED AND COULD EASILY BE MADE FROM SCRAP MATERIAL BY FOLLOWING THE PATTERN SHOWN IN FIG. S25.
SHELF MEASUREMENTS If you desire to make a shelf for your saw, use the diagram below for the size of plywood and placement of holes. Be sure to attach the shelf to the stand and mobility kit while it is still upside down during the assembly procedure. The shelf, once cut, will be attached by driving wood screws through the holes in the overhang of the leg supports. 191/4” (489 mm) /8” 3 (9.5 mm) 10” 227/16” (254 mm) (570 mm) 67/32” (158 mm) /8” 3 Drill holes using 5/16” drill bit (9.
