6.2 Tools required for assembly 6.0 Setup and assembly Wrenches, 10mm and 19mm #2 cross point screwdriver Pliers 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. 6.3 Unpacking and cleanup 1. Inspect all contents for shipping damage. Compare contents of shipping carton with contents list in this manual. Report any damage or part shortages to your distributor. 2.
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. CAUTION: Spring-tensioned stop bracket (see Figure 7-1) must be rotated out of the way before raising bow. Figure 6-7: installing work stop (712 only) 6. Slide pulley cover (A, Figure 6-8) over spindles and secure with screws and washers (HP2/HP3), using 10mm wrench. 7. Install lock screw (HP1) to secure pulley cover.
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.
reconnection, the tool should comply with all local codes and ordinances. Ampere Rating Not More More Than Than 00 06 06 10 10 12 7.2 Voltage conversion Conversion from 115V to 230V must be done by a qualified electrician. The Band Saw is prewired for 115 volt. To change incoming leads for 230 volt operation: 1. 12 Open main motor junction box cover, and change leads based on wiring diagram inside cover. This diagram is also shown in Figure 72.
8.3 Blade Speed complete, reinstall coolant valve assembly and tighten set screw (C). 5. Verify that blade guide bearings are set correctly in relation to blade (see sect. 8.6). 1. Disconnect band saw from power source. 2. Place bow in horizontal position. 3. Open pulley cover, and loosen hex nuts (K, Figure 8-5). Turn screw (L) out to relieve pressure on motor mount plate. 4. Turn screws (M) clockwise to push motor mount plate, relieving tension on belt. 5.
Figure 8-8 Figure 8-7: blade guide adjustment 8.5 Blade replacement A general-use variable-tooth blade is provided with this band saw. 8. Install red blade guard with screws. 9. Tension blade fully (see sect. 8.8 Blade tension.) 10. Place two to three drops of lightweight oil on blade. 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.
8.7 Chip brush set screw and allow blade to respond to changes. The wire chip brush must be properly adjusted and maintained in working condition; otherwise damage to blade can occur. Adjust brush so that its bristles overlap blade. Keep fingers clear of blade and wheel to avoid injury. Replace brush if it becomes worn or damaged. 8. Test the setting by placing a six-inch length of paper between blade and wheel. The paper should not be cut as it passes between wheel shoulder and blade. 9.
6. Use a micrometer to measure the thickness variation of the disk you have cut from the bar stock. Measure at top and bottom of disk. Figure 8-12: feed rate adjustment 8.12 Counterbalance spring The counterbalance spring helps control amount of weight, or feed pressure, the bow puts on workpiece when hydraulic control valve is fully open. The hydraulic cylinder will not compensate for improper counterbalance.
8.13 Blade-to-table squareness The blade must be perpendicular to table to ensure a straight cut. This setting should be confirmed by the user. Special blade setting gauges can be purchased for this type of inspection; however, it can also be done using more common shop items, as follows. 1. “Extend” the blade surface by clamping a straight, flat object to blade. (Figure 8-14 uses small, lightweight aluminum ruler.) Use lightweight clamp. 2. Place square on table and against ruler.
8.16 Vise positioning (712 only) 3. Clamp a round section workpiece in the vise. The workpiece should be 2 inches or larger in diameter. To set vise for 90 to 45 degree cutting: 1. Remove bolt and nut assemblies (F, Figure 817). 4. Set the saw on low speed. Start the cut with a very light feed rate. 2. Position vise and reinstall as shown in Figure 817. Pay particular attention to bolt hole location. 5. 3. Set vise to desired angle, reinstall nuts and bolts, and tighten nut and bolt assemblies.
Check guide bearings frequently to make sure that they are properly adjusted and turning freely. Periodically inspect belt for wear or fraying. Replace if needed. To prevent corrosion of machined surfaces when a soluble oil is used as coolant, pay particular attention to wiping dry the surfaces where fluid accumulates and does not evaporate quickly, such as between machine bed and vise. Figure 9-1: clamping positions 4. Adjust left blade guide to minimize exposed blade area. 5.
10.2 Coolant level 10.3 Additional servicing Maintain coolant level. Low coolant level can cause foaming and high blade temperatures. Replace dirty coolant; dirty or weak coolant can clog the pump, cause crooked cuts, a low cutting rate and/or permanent blade damage. To fill tank, pour coolant into hole through strainer cup to about 80% of full capacity. Full capacity is 9 liters (2.5 gal). Follow coolant manufacturer’s instructions for proper use and disposal.
11.2 Operational problems Symptom Cuts not square. Miter cuts not accurate. Premature dulling of blade teeth 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. Low blade tension. Properly secure workpiece by tightening vise handles. If irregular-shaped workpiece, use appropriate clamping technique or jig. Increase tension.
