EUROPEAN SERVICE SUPPORT GROUP SERVICE DATA BULLETIN Subject : Alignment Procedures Page 1 of 5 Equipment Needed: The following pieces of equipment are needed to properly align the saw. Description C-Clamp with 5/16” shank Dial Indicator Holder with 1/4” shank Clamp with holes for 1/4” and 5/16” shanks Part Number 233802-00 233802-01 233802-02 233802-03 Qty 1 1 1 1 Assembly: 1. In the indicator box there is a small piece of paper with diagrams on both sides.
Page 2 BLADE ALIGNMENT CONTINUED BLADE POSITIONING (LEFT TO RIGHT) Objective: To insure the blade is properly located (side to side) within the throat plate slot. This procedure sets the initial adjustment before checking for parallelism. Note: The front trunnion bracket (ITEM 6) is preset at the factory to be a precise distance from the front edge of the table. Do not loosen both the rear trunnion and front trunnion screws at the same time or proper front to back orientation will be lost. Procedure: 1.
Page 3 BLADE ALIGNMENT CONT’D. Blade Alignment (Parallelism) at 0° Bevel Objective: To assure that the tolerance, from the front of the blade to the rear of the blade, (with respect to the miter gauge slot on the right side of the table) is within design specifications. Procedure: 1. Raise blade height to full up position then back off a half a turn. 2. Slide the miter gauge assembly (ITEM 111) into the slot on the right side of the table. Make sure the slot is free of any debris. 3.
Page 4 Bevel Blade to 45° Objective: Same as above except this time the blade is beveled to 45°. Procedure: 1. The allowable tolerance for the blade at 45° from the front of the blade to the rear is +/-.016” over 8.25”. 2. With the indicator at the front of the blade, note the needle reading. 3. Slide the fixture forward while rotating the blade and measure the SAME tooth now at the rear of the blade. Be sure to keep the indicator off of the painted edge and the carbide tooth. 4.
Page 5 WORM GEAR Objective: Bevel worm should turn smoothly through entire range without binding. Procedure: 1. Bevel the saw to 0° and loosen the two bevel gear screws (ITEM 5) one-quarter turn. 2. Loosen left (bevel) stop screw (ITEM 3) until top of screw is flush with bottom of miter gauge slot. 3. Then bevel until 0° stop is solidly engaged. 4. To obtain proper gear clearance, rotate bevel crank wheel clockwise three full turns while at the same time keeping downward pressure on the crank wheel. 5.

DW746 CONTRACTORS SAW - STRIPDOWN REPAIR PROCEDURE If the dust extractor (49) needs cleaning/clearing, loosen the two screws (31) and pull off from the shroud (29/30). To remove/change the belt (50) turn the rise and fall handle (77) to it’s lowest point, lift the motor assembly to release the tension on the belt, which can now be removed. The belt is supplied fitted to the machine. If the belt shape is distorted this can cause excessive vibration.
Motor assembly removal Lift the complete motor assembly back to slowly release the main spring (33), the motor will need to be supported at all times. The main spring “unscrews” off of the casting mounting point (15). Note that the spring only fits onto the casting one way. Remove the clip securing the pivot pin in place. Push the pin through the bracket and lift off the motor assembly. (40).
(10), spring washer (11), steel washer (9), and nylon sleeve (12). The gear will now screw out and through the trunnion bracket (6) (take care not to lose the sleeve and spacer). The bevel gear (28) is removed by taking out the two Torx 50 screws (5). Trunnion brackets If for any reason you need to remove the main cradle housing (15) you must only removeeither the front or rear trunnion brackets (6/4) in order to do this.
To set the worm gear and bevel gear correctly, fit the handle (77) and wind to set the bevel cut position to 0º tight against the stop/adjusting screw (3). This has the effect of meshing the two gears together, providing a good fit. Now unwind the handle 1 to 2 turns, and tighten the bevel gear fixing screws (5). Put the blade arbor and flange assembly (19) through the arbor bracket (18), fit the spring washer (23), then put the pulley bearing (24) over the spring washer and press into the housing.

ENGLISH • Remove any remaining packing material from the saw. Your saw was shipped with an anti-corrosion coating on the table top. • Carefully clean the table top using a mild solvent cleaner. Identifying the hardware parts (fig. B) We recommend that you unpack and sort all hardware parts.
ENGLISH • Place the outfeed table (17) on the floor with the flat side down (fig. F8). Use a piece of cardboard to avoid damaging the table surface. • Mount the L-shaped brackets (25) as shown, using 2 hex head bolts (28), lock washers (35), flat washers (33) and nuts (31). Do not fully tighten. • Depress the locking pins (46) and unfold the leg (47). • Place the table on the back of the saw so that the brackets mounted to the table rest on the brackets mounted to the saw (fig. F9).
ENGLISH The riving knife can be set to two different positions. In order to obtain optimum grooving capacity, the riving knife is set to the lowest position, which limits the maximum depth of cut. In order to obtain the maximum depth of cut, the riving knife is set so that its top is no more than 2 mm above the highest tooth tip of the saw blade (fig. K2). • Set the riving knife so that the closest point is between 3 and 5 mm away from the saw blade.
ENGLISH DW746T - Checking the direction of rotation (fig. A1 & Q) If you have the DW746T, you must check the direction of rotation of the saw blade before first use. • Switch the saw on as described below. • Check if the saw blade rotates clockwise when seen from the left side of the saw. • Switch the saw off. • If the blade rotated in the wrong direction, unplug the cable and rotate the two pins (98) in the connector (9) by 180° as shown.
ENGLISH Sharp edges. Mounting and using a dado head The dado head must always be used together with the special dado throat plate (DE7466) which is available as an option. The dado head is used for cuts which are wider than the saw kerf. • Remove the blade guard assembly and the blade. • Replace the inner clamp washer by the outer clamp washer. • Mount the dado cutter blades. • Secure the dado head using the standard arbor nut. • Lower the dado head into position for the depth of cut required.
