4. 5.0 Setup and assembly If closer reach is needed toward blade, insert small rod (A4) and tighten with wrench on rod flat. 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. 5.1 Shipping contents 1 2 1 1 1 Band saw Wheels Work stop assembly Vertical cutting platform Chip bin (10” models only) Figure 5-2: installing work stop 5.
circuit with a grounded outlet that looks like the one pictured in A, Figure 6-1. grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. Note: In Canada, the use of a temporary adaptor is not permitted by the Canadian Electrical Code, C22.1. Before connecting to power source, be sure switch is in off position.
6.3 Extension cords The use of extension cords is discouraged; try to position machines near the power source. If an extension cord is necessary, make sure it is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 2 shows correct size to use depending on cord length and nameplate ampere rating.
that they straddle the work, severe damage to workpiece and blade can result. 1. Disconnect band saw from power source. 2. Raise bow to convenient position. 3. Open wheel guards and prop them open with the attached rods (G, Figure 7-5). Remove red blade guards (H). It is essential that red blade guards be re-installed after new blade has been fitted. Failure to comply may cause serious injury. Figure 7-3: blade speeds (rounded off) 7.4 Blade guide arms 1. Disconnect band saw from power source. 2.
8. Install red blade guards. 4. 9. Tension blade fully (see sect. 7.7) Note: A new blade should be re-checked for proper tension after a few minutes’ operation. 10. Place two to three drops of lightweight oil on blade. Return blade guide arm to operating position. 7.7.2 Tracking 11. Adjust blade guide bearings (see sect. 7.6). Blade tracking adjustment requires operating saw with wheel guards open. This adjustment must be completed by qualified persons only.
9. 7.8.1 Test cut to verify adjustment When paper is cut, back off set screw slightly. This assures that blade is not pushing excessively against wheel shoulder. Test cuts can be used to determine whether or not the blade is accurately adjusted. Use 2-inch round bar stock to perform these test cuts, as follows: 10. Once tracking is set, tighten hex nuts (N1). Figure 7-8: blade tension and tracking 1. With bar stock securely clamped in vise, make a cut through the bar stock. (See Figure 7-10.) 2.
The hydraulic cylinder resists bow movement in downward direction. It offers no resistance when bow is raised. A good indication of proper feed pressure is the color and shape of the cutting chips. If chips are thin or powdered, increase feed pressure. If chips are burned and heavy, decrease feed pressure. If they are still burned and heavy, reduce blade speed. Optimum feed pressure has been set when chips are curled, silvery, and warm. To increase feed rate, turn dial (R1, Figure 7-11) counterclockwise.
Speed/FPM 64 132 247 Material Tool Steel, Stainless Steel, Phosphor Bronze, Cast Iron, Malleable Iron Mild Steel, Hard Brass, Bronze Soft Brasses and Bronzes, Hard Aluminum, Plastics Table 3 A coarse blade could be used for a solid steel bar but a finer tooth blade would be used on a thin-wall tube. In general, the blade choice is determined by the thickness of the material; the thinner the material, the finer the tooth pitch.
8.3 General operating procedure IMPORTANT: When cutting magnesium, never use soluble oils or emulsions (oil-water mix) as water will greatly intensify any accidental magnesium chip fire. See your industrial coolant supplier for specific coolant recommendations when cutting such material. 1. Give machine an overall inspection. Verify that all guards, covers, etc. are in place and in working order, the blade is tensioned properly and tooth direction matches arrow on bow.
To change gear box oil: 9.0 User-maintenance 1. Disconnect machine from power source. Always disconnect power to machine before performing maintenance. Failure to do this may result in serious personal injury. 2. Place bow in horizontal position and allow a few moments for oil to settle. 3. Remove drain plug (A, Figure 9-1) and drain oil into suitable container. Reinstall drain plug. Keep all surfaces clean and free of rust, slag, chips, and coolant build-up. 4.
10.0 Troubleshooting HVBS-DM series Band Saws Symptom Excessive blade breakage Possible Cause Correction* Material loose in vise. Clamp work securely. Incorrect speed or feed. Saw blade in contact with workpiece before saw is started. Blade rubs on wheel shoulder. Check machinery handbook for speed/ feed appropriate for material being cut. Check machinery handbook for recommended blade type. Adjust blade tension to the point where the blade just does not slip on the wheel.
Symptom Teeth missing/ripped from blade Motor running too hot Possible Cause Correction* Blade tooth pitch too coarse for workpiece. Feed too slow; feed too fast. Use blade with finer tooth pitch. Workpiece vibrating. Clamp workpiece securely. Gullets loading up with chips. Blade tension too high. Use blade with coarse tooth pitch; reduce feed pressure. Brush blade to remove chips. Reduce tension on blade. Drive belt tension too high. Reduce tension on drive belt.
