168.13 Blade-to-table squarenessThe blade must be perpendicular to table to ensurea straight cut. This setting should be confirmed bythe user. Special blade setting gauges can bepurchased for this type of inspection; however, it canalso be done using more common shop items, asfollows.1. “Extend” the blade surface by clamping astraight, flat object to blade. (Figure 8-14 usessmall, lightweight aluminum ruler.) Uselightweight clamp.2. Place square on table and against ruler. Thesquare should lie flat against ruler without agap.3. If there is a gap, loosen bolt (Q, Figure 8-9) oneach blade guide assembly and rotate bladeguide assembly until gap is eliminated betweensquare and ruler.4. Retighten bolts (Q, Figure 8-9).5. After making this adjustment, be sure toreinspect other blade adjustments as noted inthis manual.Figure 8-14: table/blade squareness8.14 Auto shut-off adjustmentThe saw is properly adjusted when blade shuts offjust after cut completion. To set this:• If saw completes cut but blade continuesmoving, adjust trip tab (V, Figure 8-15)downward.• If blade stops before cut is complete, adjust triptab (V) upward.• If blade stops descending and continuesrunning without completing the cut, turn stopbolt (W) down.Figure 8-15: shut-off adjustment8.15 Vise positioning (712D only)Use handwheel (A, Figure 8-16) to move floating jawto open and close vise.To move complete right jaw assembly, loosenhandle (B).Vise can be adjusted for square and miter cuts.Loosen handle (C), pull out stop pin (D), and rotatefence to desired angle on scale. For standard angles(0/15/30/45 deg.), allow stop to reengage at detent,otherwise rotate stop to keep it disengaged.NOTE: Scale is for reference only; check angleswith protractor if greater precision is needed. (Model712 scale is located at rear of bed.)Slightly loosen handle (D) on floating jaw to allow itto conform to tapered or irregularly-shaped pieces.Then tighten handle before operating.TIP: Always verify 90-degree vise position by usinga square against blade and vise.The vise handles are adjustable. Pull up on handleand rotate it on pin, then allow it to drop back ontopin. Make sure vise handles are positioned toprevent contact with descending bow.Figure 8-16: vise positioning (712D only)
