blahblahblah 20. Keep visitors a safe distance from the work area. Keep children away. 21. Make your workshop child proof with padlocks, master switches or by removing starter keys. 22. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that can result in serious injury. 23. Maintain a balanced stance at all times so that you do not fall or lean against the blade or other moving parts.

Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Table Saw is assembled and running properly. Compare the contents of your container with the following parts list to make sure all parts are intact. Missing parts, if any, should be reported to your distributor.
Installation and Assembly Tools required for assembly: 7/16, 9/16, 3/8 and 1/2” wrenches 1/8 and 3/32” hex wrenches Flat head screwdriver Hammer and wood block (or rubber hammer) 1. Remove box and wood crating completely from around saw. 2. Use a 9/16” wrench to remove the carriage bolt, hex nut and washer holding the extension wings together (Figure 1). Set extension wings aside for later installation. Figure 1 3. With a 7/16” wrench, remove the lag screws (Figure 2) holding the saw to the wood pallet.
3. Level the extension wing with the saw table across its entire width, using a straight edge and hammer with block of wood (or rubber hammer). See Figure 5. As each area of the wing becomes flush with the table, tighten the screw under that area. Continue until all three screws are fully tightened. 4. Repeat for the other extension wing. Installing Blade NOTE: The blade must be mounted first before rails can be adjusted.
2. With a 3/8" wrench, reach through the motor opening in the stand and tighten the square head setscrew (A, Figure 8) into the groove of the shaft. (NOTE: The groove will be in the proper position if the end of the shaft is made flush with the opposite side of the trunnion hole.) Then tighten the hex nut (B, Figure 8) up against the trunnion. 3. The upright member of the rear splitter support (C, Figure 9) must be oriented toward the right of the shaft, as observed from the rear of the saw. 4.
Make sure the voltage of your power supply matches the specifications on the motor plate of the machine. Extension Cords If an extension cord is necessary, make sure the cord rating is suitable for the amperage listed on the machine's motor plate. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating. The chart in Figure 11 shows the correct size cord to use based on cord length and motor plate amp rating. If in doubt, use the next heavier gauge.
5. The blade must be kept centered with the slot in the table insert to ensure clearance at both the 90 degree and 45 degree positions. After alignment, secure the table to the cabinet by re-tightening the three mounting screws (Figure 15). Tilt Stop Adjustment Using a combination square, check the 90 degree (0) and 45 degree stops. (Figure 16 shows the 90 degree stop being checked.) Adjust stop positions if required, using the stop screws as shown.
Splitter Alignment One of the most critical adjustments to help avoid kickback is the splitter adjustment. It should be checked and readjusted, if required, after each blade change. 1. Lift the miter gauge bar slightly out of its slot. Place a combination square against the side of the raised up miter gauge bar and slide the scale against the top of the blade tooth and against the splitter as shown in Figure 19. 2. Check the splitter for parallelism and for clearance to the miter slot.
If the saw raising arm has been re-located, the table may have to be realigned so as to provide clearance between the saw blade and table insert slot. The splitter will also have to be realigned. NOTE: The saw arm setscrew must be tight to avoid the possibility of movement which could cause the blade to hit the insert. Tilting Mechanism Adjustment If binding occurs in the tilting mechanism, clean off the saw dust and pitch accumulation and regrease.
• Applying feed force when ripping to the cutoff (free) section of the work piece instead of the section between the saw blade and fence. • Ripping wood that is twisted (not flat), or does not have a straight edge, or has a twisted grain. 3. To minimize or prevent injury from kickbacks: Avoid conditions listed above. Wear a safety face shield, goggles, or glasses.
9. Bevel ripping cuts should always be made with the fence on the right side of the saw blade so that the blade tilts away from the fence and minimizes the possibility of the work binding and the resulting kickback. Rip Sawing 1. Ripping is where the work piece is fed with the grain into the saw blade using the fence as a guide and a positioning device to ensure the desired width of cut. See Figure 26. Before starting a rip cut, be sure the fence is clamped securely and aligned properly.
6. Never push in a location such that the pushing hand is in line with the blade. Move the hand serving as a hold-down a safe distance from the blade as the cut nears completion. 7. For very narrow ripping where a push stick cannot be used, use a push block or auxiliary fence. Always push the workpiece completely past the blade at the end of a cut to minimize the possibility of a kickback. 8.
3. For 90 degree crosscutting, most operators prefer to use the left-hand miter gauge slot. When using it in this position, hold the workpiece against the miter gauge with the left hand and use the right hand to advance the workpiece, as shown in Figure 32. When using the right hand slot for miter and compound crosscutting so that the blade tilts away from the miter gauge, the hand positions are reversed. 4. When using the miter gauge, the workpiece must be held firmly and advanced smoothly at a slow rate.
NOTE: When making compound miters (with blade tilted) use the miter gauge in the right hand slot to provide more hand clearance and safety. 3. Have the blade extend only 1/8" above the top of the workpiece. Exposing the blade above this point can be hazardous. Dado Cutting Dadoing is cutting a wide groove into a workpiece or cutting a rabbet along the edge of a workpiece. A dado insert, shown in Figure 36, is necessary for this type of operation. Do not use the standard table insert for dadoing operations.
Alternatively, drilled and tapped holes in the table top allow the use of wing nuts and washers as a method of clamping. If this method of fastening is used, provide slots in the feather board for adjustment. Figure 37 shows a method of attaching and use of the feather board as a vertical comb. The horizontal application is essentially the same except that the attachment is to the table top. Filler Piece (Figure 38).

Troubleshooting Trouble Excessive vibration. Cuts out-of-square when crosscutting. Motor stalls or workpiece binds or burns. Cuts not true at 90 or 45 degrees. Tilt or saw raising handwheels difficult to turn. Probable Cause Remedy Tilt or raising clamp knobs not tightened. Tighten knobs. Blade out of balance. Change blade. [page 9] Bad motor. Replace motor. Loose arbor or motor sheave. Tighten set screws. [page 13] Miter gauge out of adjustment. Reset stops and pointer.
