5.0 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. Compare the contents of your container with the following parts list to make sure all parts are intact. Missing parts, if any, should be reported to your distributor. Do not discard any packing materials until saw is assembled and operating satisfactorily.
5.3 Assembly of Stand 5. Insert axle (L) through holes of wheel base (D). See Figure 5-3. 6. Install wheel (H) and two 5/8”x30mm flat washers (HP6) on each side of wheel. Insert cotter pins (HP7) through holes on each end of axle and bend the ends of the cotter pins to secure wheel on axle. 7. Install handle (J) to left side plate (A) with four 5/16x1-1/2 hex cap screws, four flat washers and four hex nuts (HP3/4/8). Tighten hex nuts. 8. Install two rubber feet (F) on bottom of left plate (A).
5.4 Mounting band saw to stand 5.6 Stock stop Remove any plastic or holding straps from around the band saw. Areas of the machine have been given a protective coating at the factory; this should be removed using a soft cloth moistened with kerosene or a cleaner-degreaser. Do not use gasoline, paint thinner, or lacquer thinner as these will damage painted surfaces. Do not use an abrasive pad. The stock stop is used for making multiple cuts of the same length. Saw is heavy; two-person lift is recommended.
Note: In Canada, the use of a temporary adaptor is not permitted by the Canadian Electrical Code, C22.1. 6.0 Electrical connections The HBS-56MVS Band Saw is rated for 115-volt power. The band saw comes with a plug designed for use on a circuit with a grounded outlet that looks like the one pictured in A, Figure 6-1. Before connecting to power source, be sure switch is in off position. It is recommended that the band saw be connected to a dedicated 15 amp circuit with circuit breaker or fuse.
7-2. The square should lie along entire length of jaw and blade without a gap. 7.0 Adjustments 7.1 Tools required for adjustments (Not all may be needed depending on adjustment.) Wrenches 10, 12, 14mm Hex wrench 6mm Square Straight edge Small clamp 7.2 Blade-to-table squareness The blade must be perpendicular to table to ensure a straight cut. This setting should be verified during initial setup.
7.5 Downfeed stop assembly to other set of holes. Tighten screws securely. The weight of the bow guides the blade through the workpiece. The stop screw (G, Figure 7-3) prevents blade from contacting base after the cut. It has been adjusted by the manufacturer. If future adjustment is needed, loosen hex nut and rotate screw then retighten hex nut. 4. Remove stop screw (D, Figure 7-2) and swivel bow until pointer lines up with 60° on scale. Tighten handle (B, Figure 7-2).
gained, the operator should develop a better “feel” for how tight to set a particular blade. Tick marks can be made on the tension knob for quickly resetting tension when re-installing a blade. 7.10 Blade tracking Blade tracking adjustment requires running saw with back cover open. Use caution when making this adjustment. Failure to comply may cause serious injury. Blade tracking has been set by the manufacturer and should not require adjustment.
7.12 Blade replacement 7.13 Feed pressure adjustment Use caution and proceed slowly when working with or around a band saw blade. Use work gloves when handling it. The spring (Figure 7-9) moderates downfeed pressure of bow. Turn screw with 12mm wrench, clockwise to decrease pressure, counterclockwise to increase pressure. 1. Disconnect band saw from power source. 2. Remove back blade cover, and red blade guards. It is essential these red guards be installed after new blade has been fitted.
General rule for band saw blade speed: The harder the material being cut, the slower the blade speed. A minimum of three teeth should be on the work piece at all times for proper cutting. The blade and workpiece can be damaged if the teeth are so far apart that they straddle the workpiece. For very high production on cutting of special materials, or to work hard-to-cut materials such as stainless steel, tool steel, or titanium, ask your industrial distributor for more specific blade recommendations.
2. Position workpiece in vise and tighten vise. Workpiece should be fitted directly between jaws without adding other objects. When workpiece is profiled section, flat piece or special shape, refer to examples in Figure 8-1 for proper clamping positions. The top row shows acceptable clamping positions, the bottom row shows unacceptable positions. 9.0 User-maintenance Before doing maintenance on the machine, disconnect it from the electrical supply by pulling out the plug or switching off the main switch.
6. 9.3 Lubrication Install new brush (or reinstall current brush) and gently press it all the way into hole until brass clip is secured. 7. Install cap. 8. Repeat for other brush. 9. Reinstall motor sleeve and screws. Ball bearings on blade guide assemblies and blade wheels are permanently lubricated and sealed, and require no further lubrication. Periodically lubricate the vise leadscrew as needed with #2 tube grease. 9.
10.0 Troubleshooting HBS-56MVS Band Saw 10.1 Operational problems Symptom Cuts not square. Premature dulling of blade teeth. Rough cut. Frequent blade breakage. Possible Cause Correction Blade not square to vise/material. Adjust vise square to blade. Blade surface not perpendicular to table. Workpiece shifting in vise. Adjust blade guides until perpendicular. Properly secure workpiece. Low blade tension. Increase tension. Blade guides out of adjustment. Adjust blade guides.
10.2 Mechanical and electrical problems Symptom Motor will not start. Motor will not start, or motor stalls, resulting in blown fuse or tripped breaker. Motor overheats. Possible Cause Correction * Low voltage. Check power line for proper voltage. Open circuit in motor or loose connection. Overload condition. Inspect all lead connections on motor for loose or open connections. Allow machine to cool down, then re-start. Too many tools running on one circuit. Motor brushes worn.
