6.0 Setup and assembly Read and understand all instructions before attempting assembly. Band Saw must be disconnected from power during all assembly procedures. Failure to comply may cause serious injury. 6.1 Shipping contents See Figures 6-1, 6-2.
3. Remove shipping bracket (Figure 6-4). Then reinstall bottom hex nut beneath plate. Retain shipping bracket in case machine must be transported in future. rod and secure with thumb screw. See Figure 6-7. Figure 6-7: installing work stop (712V only) Figure 6-4: shipping bracket removal 4. Install handle with flat washers and nut (C, Figure 6-5), using 19mm wrench. To install, raise bow to vertical position and open guard.
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Verify that blade guide bearings are set correctly in relation to blade (see sect. 8.6).
8.3 Drive belt tension/replacement 8.5 Blade replacement 1. Disconnect band saw from power source. 2. Open pulley cover, and loosen hex nuts (K, Figure 8-5). Turn screw (L) out to relieve pressure on motor mount plate. A general-use variable-tooth blade is provided with this band saw. 3. Choice of blade pitch is governed by thickness of workpiece: the thinner the workpiece, the more teeth advised. A minimum of 3 teeth should engage workpiece at all times.
. Run saw and make sure blade is tracking properly (sect 8.9. Blade tracking.) 8.9 Blade tracking 14. Follow blade break-in procedures (sect. 9.1). Blade tracking adjustment requires running saw with rear guard open. This adjustment must be completed by qualified persons only. Failure to comply may cause serious injury. 8.6 Blade guide bearings 1. Disconnect machine from power source. 2. Loosen bolt (Q, Figure 8-9) and adjust assembly so that rear bearing (R1) is approximately 0.002 to 0.
If you do not have a piece of 2-inch bar stock available for a test cut, use a larger diameter test piece rather than a smaller one. The maximum thickness variation on any test piece should be no more than 0.003 inch, per side, per inch of stock diameter. 8.11 Setting feed rate Feed rate of blade into workpiece is important to band saw performance. Excessive pressure of blade against workpiece may cause stalling or blade breakage. In contrast, insufficient pressure rapidly dulls the blade.
3. Place a weigh scale (such as spring or hanging scale) beneath blade tension handle, and lift saw bow. Scale should indicate approximately 5 to 6 kg (11-13 lb). 4. If adjustment is needed, loosen one nut and tighten the other (Figure 8-13) on eye bolt, until scale indicates 5 to 6 kg (11-13 lb). A good indication of proper feed pressure is the color and shape of the cutting chips. If the chips are thin or powdered, increase feed pressure. If the chips are burned and heavy, decrease feed pressure.
Slightly loosen handle (E) on floating jaw to allow it to conform to tapered or irregularly-shaped pieces. Then tighten handle before operating. 9.0 Operation 9.1 Blade break-in TIP: Always verify 90-degree vise position by using a square against blade and vise. New blades are very sharp and, therefore, have a tooth geometry which is easily damaged if a careful break-in procedure is not followed. Consult the blade manufacturer’s literature for break-in of specific blades on specific materials.
3. Position workpiece in vise and tighten vise. Workpiece should be fitted directly between the jaws without adding other objects. When work piece is profiled section, flat piece or special shape, refer to examples in Figure 9-1 for proper clamping positions. The top row shows acceptable clamping positions, the bottom row shows unacceptable positions. 10.0 User-maintenance Always disconnect power to machine before performing maintenance. Failure to do this may result in serious personal injury.
5. 6. Hold a container under lower right corner of gear box with one hand while slowly raising bow with the other. Drain completely. Follow local regulations for used oil disposal. Return bow to horizontal position. Wipe out remaining oil with a rag. 7. Replace gasket and cover. Fasten cover with screws. 8. Remove vent plug (Figure 10-1) with 8mm wrench, and fill gear box with approximately 1/2 pint of 90W oil, through the hole. Reinstall vent plug. 9. 1. Disconnect saw from power source. 2.
11.0 Troubleshooting HVBS-712V/712DV Band Saw 11.1 Mechanical and electrical problems Symptom Motor will not start. Possible Cause Correction * No incoming power. Check plug connection. If satisfactory, check breaker or fuse. Check power line for proper voltage. Low voltage. Motor will not start, or motor stalls, resulting in blown fuse or tripped breaker. Motor overheats. Machine slows when operating. Loud, repetitive noise coming from machine. Excessive vibrations. No coolant flow.
Symptom Cuts not square (cont.) Miter cuts not accurate. Premature dulling of blade teeth Possible Cause Correction Blade is worn, cutting crooked. Replace blade. Feed pressure too great. Reduce feed pressure. Blade guides incorrectly set. Readjust guide assemblies. Incorrect blade toothing in relation to workpiece. Improper setting of vise jaws. Blade worn; cutting crooked. Check Machinery’s Handbook for recommended blade type. Use adjustable square or protractor to verify angle settings.
