7.0 Set-Up and Assembly Tools required for assembly: 12mm wrench 3, 4, and 6mm hex keys 7.1 Unpacking and cleanup Inspect contents of shipping container for shipping damage. Report any damage to your distributor. Remove all contents from carton, and compare to the contents list in this manual. Report any part shortages to your distributor. Do not discard carton or packing material until machine is assembled and running satisfactorily. Exposed metal areas have a rust preventative applied.
Figure 4 4. Use properly rated lifting equipment (hoist or forklift) with straps placed beneath cast iron portion of saw. 5. Band Saw should be disconnected from electrical power during assembly and setup. Position saw atop base and secure with four screws and washers (HP-1/6/7). 6. Install work stop assembly (A/B/C) into hole on saw base. 1. Assemble base parts (J,K) according to Figure 4. 7. Install handle (G), and place filter screen (D) over coolant drain hole in pan. 2.
7.4 Vertical cutting plate These steps are only necessary when using band saw in vertical position. 1. Disconnect machine from power source. 2. Open valve on hydraulic cylinder (lever parallel to cylinder) and raise bow to vertical position. 3. Remove two screws and remove seat plate, as shown in Figure 5. Figure 7 Figure 5 4. Guide blade through slot in vertical cutting plate (F, Figure 5), and tighten with the two screws. 5.
7.6 Coolant system Local codes take precedence over recommendations. Make sure there is coolant in the tank before operating, to prevent damage to pump. 8.1 Grounding instructions 1. All Grounded, Cord-connected Tools: Use of a water-soluble coolant will increase cutting efficiency and prolong blade life. Do not use black cutting oil as a substitute. 1. Remove coolant return hose (A, Figure 10) from filter cup, and slide tank out of saw base. 2. Fill tank to approximately 80% of capacity.
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in D, Figure 11. The tool has a grounding plug that looks like the plug illustrated in D. Make sure the tool is connected to an outlet having the same configuration as the plug. No adapter is available or should be used with this tool.
9.0 Adjustments The settings on your band saw, such as blade squareness and tracking, were carefully performed by the manufacturer. You should, however, verify these before operating, in case misalignment has occurred during shipping. 9.1 Squaring blade to table 1. Disconnect machine from power source. 2. Place machinist’s square (A, Figure 14) on table and against blade. 3. Check to see that blade contacts the square along entire width of blade. 4.
9.4 Miter cuts 1. Loosen handle (G, Figure 17). 2. Rotate bow to desired angle up to 45-degrees, using scale indicator on front of base. 3. Tighten handle. Figure 18 9.6 Counterbalance spring The counterbalance spring helps control the amount of weight the saw bow puts on the workpiece when the hydraulic control valve is fully open. The hydraulic cylinder will not compensate for improper counterbalance. Figure 17 The angle scale is sufficient for most mitering operations.
2. Raise bow to vertical position, and secure in place by turning off hydraulic cylinder. 3. Remove red blade guard (A, Figure 19) by removing two screws. 11. Close back cover and secure with knobs. 12. Install red blade guard, and brush assembly. 13. Connect machine to power source. 14. Run machine to verify that blade is tracking properly. See section 9.9, Blade tracking. Red blade guard must be reinstalled after new blade is fitted. 9.
Blade tracking has been tested at the factory. Adjustment is rarely required when the blade is used properly and if the blade is correctly welded. If a tracking problem occurs, first inspect blade condition, then adjust tracking as follows: accurate, quieter cutting and longer machine and blade life. 9. When the paper is cut, back off the set screw slightly. This assures that the blade is not touching the flange of the wheel. 1.
9.11 Setting blade speed 1. Turn machine OFF. 2. Loosen knob (A, Figure 23) and open pulley cover. 3. Reduce belt tension by turning the two screws (B, Figure 23) counterclockwise. 4. Slip belt over pulleys for desired speed, according to chart inside pulley cover (also shown in Figure 24). 5. Tighten screws to tension belt. Proper tension is when center of belt can be pushed with a finger approximately 1/2-inch.
Figure 27 9.13 Chip brush The chip brush (B, Figure 19) must be properly adjusted and maintained in working condition; otherwise damage to blade can occur. Adjust the brush so that its bristles overlap the blade. Figure 29 9.14 Limit switch 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 magnesium.
3. When the saw has completed 1/3 of the cut, increase the feed rate slightly and allow the saw to complete the cut. 4. Keep the same hydraulic cylinder setting and begin a second cut on the same or similar workpiece. 5. 6. When the blade has completed about 1/3 of the cut, increase feed rate. Watch the chip formation until cutting is at its most efficient rate and allow the saw to complete the cut (see section 11.4, Evaluating cutting efficiency). 8. Turn on coolant flow.
Place a thin coat of oil on the table surface on which the vise jaw slides. Figure 32 Figure 31 4. Hold a container beneath lower right corner of gear box with one hand, while slowly raising bow with the other. Drain completely. 5. Place bow in horizontal position. Wipe out remaining oil with a rag. 6. Fill gear box with approximately 1/2 pint of gear oil. 7. Reinstall gasket and cover. Fasten cover with screws. 12.1 Coolant level Maintain coolant level.
Trouble Probable Cause Remedy Cuts not square. Feed pressure too great. Decrease feed pressure. 90° angle stop is not set correctly. Adjust stop until blade is square with vise. Incorrect blade toothing in relation to workpiece. Check Machinery’s Handbook for recommended blade type. Blade is worn, cutting crooked. Replace blade. Incorrect adjustment of bearing guides and guide assembly. Re-adjust guide assemblies. Workpiece incorrectly positioned in vise.
