18 ADJUSTING 90 DEGREE AND 45 DEGREE POSITIVE STOPS The machine is equipped with positive stops that will quickly and accurately position the saw blade at 90° and 45° to the table. To check and adjust the positive stops, proceed as follows: DISCONNECT MACHINE FROM POWER SOURCE. 1. Remove the blade guard and splitter. 2. Raise the saw blade to its highest position. 3. Set the blade at 90° to the table by turning the blade tilting handwheel counterclockwise as far as it will go. 4. Use a combination square (A) Fig. 33 to see if the blade is at 90° to the table surface. 5. If the blade is not at 90° to the table, loosen set screw (B) with 5/32. allen wrench (C), and turn the blade tilting handwheel until the blade is 90° to the table. Turn set screw (B) clockwise until it bottoms. 6. Adjust the pointer (D) Fig. 34 to point to the zero degree mark on the scale by loosening screws (E), adjusting pointer (D), and tightening screws (E). 7. Turn the blade tilting handwheel clockwise as far as it will go and use a combination square to see if the blade is at 45° to the table. 8. If the blade is not at 45° to the table, loosen set screw (F) Fig. 33, and turn blade tilting handwheel until the blade is 45° to the table. Turn set screw (F) clockwise until it bottoms. 9. Replace blade guard and splitter before using the Fig. 34machine. CHECKING BLADE ALIGNMENT The saw has been aligned at the factory so the saw blade is parallel to the miter gage slots; however, it is recommended to check the alignment before initial operation as follows: DISCONNECT MACHINE FROM POWER SOURCE. 1. Place a combination square (A) Fig. 35, on the table with one edge of the square in the miter gage slot, as shown, and adjust the square so the rule just touches one of the teeth on the saw blade at the forward position, as shown in Fig. 35. Lock the square in this position. 2. Rotate the saw blade so that the same tooth you used in STEP 1 is in the rear position, as shown in Fig. 36, and check this distance. Both the front and rear measurements should be identical. 3. If an adjustment is necessary see “ADJUSTING BLADE ALIGNMENT.” Fig. 33 C A B F E D Fig. 35 Fig. 36 19 ADJUSTING BLADE ALIGNMENT BLADE ALIGNMENT IS FACTORY SET AND SHOULD NOT NEED ADJUSTMENT. ADJUSTING BLADE ALIGNMENT IN THE FIELD IS A DIFFICULT AND TIME-CONSUMING PROCEDURE. ALL SAW BLADES HAVE SOME RUNOUT. THEREFORE, RE-ADJUSTING BLADE ALIGNMENT SHOULD ONLY BE ATTEMPTED IF IT BECOMES NECESSARY. (SEE CHECKING BLADE ALIGNMENT.) DISCONNECT MACHINE FROM POWER SOURCE. 1. Lower blade. Remove blade guard and table insert. With a 1/2. wrench, slightly loosen the 4 front and rear trunnion mounting bolts. NOTE: Two trunnion mounting bolts (E) Fig. 37 are shown as looking up inside side of saw. 2. Move the trunnion assembly in the desired direction. Tap gently with rubber mallet if necessary. 3. To check blade alignment, follow section “CHECKING BLADE ALIGNMENT” procedure until proper alignment is achieved. Tighten 4 trunnion bolts (E) Fig. 37. 4. Check blade alignment again after tightening bolts to confirm alignment. If alignment is off, loosen the 4 trunnion bolts (E) and repeat the above steps until proper alignment is achieved with bolts fully tightened. 5. Install table insert, blade guard, and lower blade before reconnecting power source. BACKLASH ADJUSTMENTS DISCONNECT MACHINE FROM POWER SOURCE. After a period of extended use, if any play is detected in the blade raising or blade tilting mechanisms, remove the blade and make the following adjustments: ADJUSTING BLADE RAISING MECHANISM - Loosen locknut (A) Fig. 38, and turn eccentric sleeve (B) until all play is removed. Tighten locknut (A) while holding sleeve in place. ADJUSTING BLADE TILTING MECHANISM - Loosen locknut (C) Fig. 38, and turn eccentric sleeve (D) until all play is removed. Tighten locknut (C) while holding sleeve in place. E Fig. 37 A B D C Fig. 38 20 MITER GAGE OPERATION AND ADJUSTMENT The miter gage is equipped with adjustable index stops at 90, 75, 60,45 and 30 degrees. To rotate the miter gage, loosen lock knob (A) Fig. 40, push the thumb lever (B) down and move the body of the miter gage (C) to the desired angle. The miter gage is equipped with a plate (D) Fig.41 which fits into the T-Slot groove (E) in the table. This allows the miter gage to be pulled off the front edge of the table without falling. This allows for a longer cut-off capacity in front of the blade. A B C Fig. 40 DE Fig. 41 MACHINE USE COMMON SAWING OPERATIONS Common sawing operations include ripping and crosscutting plus a few other standard operations of a fundamental nature. As with all power machines, there is a certain amount of hazard involved with the operation and use of the machine. Using the machine with the respect and caution demanded as far as safety precautions are concerned, will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or completely ignored, personal injury to the op...
