135. After making this adjustment, be sure to re-check other blade adjustments as noted in thismanual.7.10 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 switch trip (P, Figure 21)downward.• If blade stops before cut is complete, adjustswitch trip (P) upward.• If blade stops descending and continuesrunning without completing the cut, turn stopbolt (Q) down.Figure 217.11 Vise adjustmentUse handwheel (R, Figure 21) to open and closevise.Vise can be adjusted for square and miter cuts.Loosen hex cap bolts and adjust vise for the cut.Slightly loosen screw on floating vise (14mmwrench) to allow it to conform to tapered or irregular-shaped pieces. Then tighten screw beforeoperating.A scale on back side of bed aids in positioning visefor 90° cuts or a particular miter. TIP: Always verifyvise position by using a square against blade andvise.7.12 Vertical stop adjustmentThe stop screw (Figure 22) can be adjusted toensure bow is at 90-degrees when using verticalcutting plate.Figure 228.0 Operation8.1 Blade break-inNew blades are very sharp and, therefore, have atooth geometry which is easily damaged if a carefulbreak-in procedure is not followed. Consult theblade manufacturer’s literature for break-in ofspecific blades on specific materials. However, thefollowing procedure will be adequate for break-in ofJET-supplied blades on lower alloy ferrousmaterials.1. Clamp a round section workpiece in the vise.The workpiece should be 2 inches or larger indiameter.2. Set the saw on low speed. Start the cut with avery light feed rate.3. When the saw has completed 1/3 of the cut,increase feed rate slightly and allow saw tocomplete the cut.4. Keep the same hydraulic cylinder setting andbegin a second cut on the same or similarworkpiece.5. When blade has completed about 1/3 of cut,increase feed rate. Watch chip formation untilcutting is at its most efficient rate and allow sawto complete the cut (see sect. 8.3, Evaluatingcutting efficiency).6. The blade is now ready for regular service.8.2 General operating procedure1. Raise bow and secure in position using support,as shown in Figure 21.Always secure bow inraised position with support plate beforeloading material. Never start a cut with bladecontacting workpiece.2. Position workpiece in vise and tighten vise.Workpiece should be fitted directly betweenjaws without adding other objects. Whenworkpiece is profiled section, flat piece orspecial shape, refer to examples in Figure 23for proper clamping positions. The top row
