Replace cover by lining up holes in cover with holes in the raised sections of the ball retainer assembly. Replace screws and tighten securely (Fig. A13). Fig. A13 2. YOKE CLAMP HANDLE The purpose of this handle is to provide a friction lock between the -upper face of the yoke and the bottom face of the rollerhead. It should also eliminate any play between these two ■ parts. To lock, the handle is 'pushed back from the hand grip of the yoke. If at any time if is possible to move this handle so that it strikes-the-back--part-.of -.the .carriage-it is not in proper.ad-.. justment. Its proper position when locked is approximately 90® or less to the hand gri p-of the yoke. To adjust (Fig. A14): 1. Loosen the yoke lock lever by pulling it toward you. 2. Back off the screw located directly above the yoke locator pin assembly several turns, this will release lock on the large lockwasher. Using a screwdriver in the large slot on the opposite side of the carriage, turn the large lock washer one, two or three notches. Turn clockwise to tighten, counter clockwise to loosen. ( Each notch gives 15° rotation). . , DO NOT MAKE IT TIGHT. - 3. Tighten screw into a new notch in the large lock washer and tighten yoke lock"lever;Tlie-yoke lever should now be properly positioned. Fig. A14 3. ELEVATION ADJUSTMENT CAUTION: If motor tends to move down when wing nut is loose adjustment needs tightening. If the saw is too tight or too loose when elevating, it is out of ad- justment To Adjust (fig. All): 1. Remove wing nut and cupped washer from elevating shaft adjacent to guard. 2. With right hand holding elevating knob, tighten or loosen nut with wrench as shown. 3. After adjustment saw must elevate easily with minimum motor play, Motor must not drop when wing nut is loose art « must not-be easily moveable without turning elevation knob. 4.-''When-'saw>eJevation is satisfactory^ replace--: cupped--washer and tighten wing nut Fig. Ail 13 ALIGNMENT GUIDE FOR ACCURATE CUTTING It is important to realize that an improperly adjusted saw just will not yield the accurate cuts desired. If the machine seems to cut inaccurately, its adjustments and alignments should be checked. The following guide is listed for your convenience. However, changing one adjustment will affect another, so it is best to perform all of the alignment procedures when correcting any one problem. PROBLEM POSSIBLE CAUSE 1. Saw will not make a square cross cut or a Arm is not perpendicular to guide fence. good 45° miter cut. Arm not indexed to the right. Too much play between arm and base. Roller head too loose on arm. Yoke too loose when clamped to roller head. Saw dust between lumber and guide fence. Table not parallel with arm. Guide fence not straight 2. Lumber has a tendency to walk away from fence Saw blade is not parallel with fence. (Heel Adjustment) when ripping or ploughing. Arm not perpendicular to guide fence. Dull blade or cutters. 3. Saw stalls when ripping Fence not straight. or ploughing. Feed rate too fast. Wrong type blade. Arm too loose in base. Roller head too loose on arm. Yoke loose when clamped to roller head. Saw dust between lumber and fence. 4. Saw blade scores lumber, Saw blade is heeling. not giving a good finished cut. Arm too loose in base. Roller head loose in arm. Yoke too loose when clamped to roller head. Bent or dull blade. Not feeding saw properly. Using improper blade for finish cut desired. PROBLEM POSSIBLE CAUSE. 5. Saw blade or Oado blades tend to push lumber to one side when cross cut- Saw blade is heeling. Arm too loose in bast ting. Roller head too loose on arm. Yoke too loose when clamped to roller head. Fence not straight Dull blade or cutters. 6. Cut depth varies from one end of stock to the other. Table top not parallel with arm. Arm too loose in base. 7. 45° bevel cut not accurate. Saw blade not perpendicular to table top. Arm too loose in base. Roller head too loose in arm. Yoke too loose when clamped to roller head. Bevel clamp knob loose. Table top not parallel with arm. 8. Saw tends to advance over lumber too fast Roller head not properly adjusted. Dull blade. Not feeding saw properly. 9. Saw does not traverse smoothly in tracks. Roller head not properly adjusted. Dirty'tracks. Bad bearings. 10. Miter scale not accurate at various miter angles. Scale pointer not properly adjusted. 11. Clamping force not sufficient at miter angles other than 45° Base clamp out of adjustment 14 PRECUTTING (KERFING) THE WORK SURFACE READ RULES FOR OPERATION ON PAGES 7 AND 8 BEFORE STARTING MOTOR , in cutting through material placed on the saw table the bottom of the saw blade should project to about 1/16" below the bottom of the material being cut. This' causes it to cut into, the table top, making kerf mirks, unless kerfs already exist forth© particular cut being made. This section of the manual will cover the advance, or pre-cut...
