6.0 UNCRATING AND ASSEMBLY Note: Read and understand the entire manual before attempting setup or operation. 1. Finish uncrating the saw and inspect for damage. Should any have occurred, contact your local distributor. 2. Remove any preservatives with kerosene or diesel oil. Do not use gasoline, paint thinner, or any cellulosebased product, as these will damage painted surfaces. 3. Remove two socket head cap screws from left side of vertical column.
.0 CONTROLS Refer to Figures 2 and 3. Low/High Range Shift Lever (B, Figure 2) Pull toward front of machine to shift into low speed range. Push toward rear of machine to shift into high speed range. ! Move low/high range lever only while machine is STOPPED. Failure to comply may damage gearbox. Speed Selection Handwheel (V, Figure 2) Turn clockwise to increase speed, counterclockwise to decrease. Main Motor Stop Switch (I, Figure 3) Press to stop band saw.
P O Q N R U Fig. 6 Fig. 4 Blade Tension Handwheel (S, Figure 5) Located on underside of upper frame. Turn clockwise to tension blade; counterclockwise to release tension on blade. Blade Tracking Knob (T, Figure 5) Located at upper rear of the saw. Turn clockwise to track blade toward front of the blade wheel. Turn counterclockwise to track blade toward rear of the blade wheel.
stabilize the new setting. 10.3 BLADE GUIDE ADJUSTMENT B ! Blade guides must be properly adjusted or damage may occur to blade and/or guides. A ! C Guard has been removed to show detail. Always operate saw with guard in place and properly adjusted. Failure to comply may cause serious injury. Fig. 7 10.2 BLADE TRACKING Blade tracking may be required periodically depending on the blade size and tension. The blade must be tensioned as outlined in section 10.1 Blade Tensioning.
10. Turn on saw and check blade tracking. Adjust tracking if necessary. H G I F Fig. 9 Fig. 10 10.4 TOP GUIDE ADJUSTMENT Always position top guide to within 1/8” of the top surface of workpiece. This minimizes exposure of operator’s hands to the saw blade. 10.5 CHANGING SAW BLADES 1. 2. 3. 4. 5. 6. Disconnect saw from power source. Move upper blade guide to its highest position and lock in place. Open both wheel doors. Turn tension adjustment knob counterclockwise to loosen tension on blade.
11.2 TOOTH SHAPE Note: When cutting thin materials, the rule for blade pitch is to have a minimum of two teeth engaging the material being cut at all times. Standard Tooth - generally used to cut ferrous metals, hard bronze, hard brass, and thin metals. Skip Tooth - have better chip clearance (larger gullet) and are used on softer, non-ferrous materials such as aluminum, copper, magnesium, and soft brass. Hook Tooth - provides a chip breaker and has less tendency to gum up in softer materials.
3. 4. Position blade so that cut is made at a place that allows for uniform spacing of teeth. See Figure 12. Bring handle down firmly to cut blade. GRIND HERE IMPORTANT: If a blade has been cut by using snips, the ends of the blade must be ground square before welding them together, as shown in Figure 14. If snips are used to cut blade, grind ends square as shown. Fig. 13 12.3 WELDING ! Fig. 11 The welder is designed for intermittent use.
6. Set pressure selector switch (counterclockwise rota tion) to the approximate setting required for the width of the blade being welded. Misaligned Weld ! Incomplete Weld Keep hands clear of weld area and clamp jaws during welding. 7. Press and hold weld button (Figure 14). When weld button is pushed, the left clamp moves to the right to apply pressure to the blade ends. Simultaneously, sparks will be emitted from the blade ends as they are being welded.
! If blade is thicker at the weld than at the rest of the blade, using the blade may damage the guides. The following are variations of the general procedure, based upon blade type: 12.4.1 CARBON STEEL BLADES 1. Press and jog the annealing switch button until weld is a “dull cherry” to “cherry red” color. 2. Allow blade to cool slowly by decreasing jogging frequency. 12.4.2 CARBON STEEL HARD BACK BLADES 1. Heat blade slowly until weld becomes a deep blue color. 2.
3. 4. 5. 6. Bad Grindings Fig. 18 13.2 SETTING BLADE SPEED 1. 12.6 SECONDARY ANNEALING Anneal the weld 2 to 3 times again after grinding. 12.7 WELDER CLEAN-UP It is important that the welder jaws be kept clean at all times. The jaws and inserts must be wiped or scraped clean after every weld. Doing this will ensure better welds by: 1. Holding proper alignment. 2. Preventing flash from becoming embedded in the blade. 3. Preventing shorts or poor electrical contact. 13.
14.0 MAINTENANCE ! Before doing maintenance on the machine, disconnect it from the electrical supply by pulling out the plug or switching off the main switch. Failure to comply may cause serious injury. Use a brush to loosen accumulated chips and debris. Use a shop vacuum to remove the debris. Make sure the chip brush on the lower band wheel is properly adjusted. If the power cord is worn, cut, or damaged in any way, have it replaced immediately.
15.0 TROUBLESHOOTING 15.1 OPERATING PROBLEMS Table 1 Trouble Saw blade is twisted. Cuts not straight. Blade slips off wheel(s). Blade quickly becomes dull. Blade warps. Band Saw is noisy, or vibrates too much. Blade teeth keep breaking. Blade becomes damaged easily. Probable Cause Remedy Blade has been improperly welded. Re-weld blade. See section 12.3 Blade not installed properly. Set guide inserts closer, and increase blade tension. Feeding workpiece too forcefully. Decrease feed rate.
15.2 MECHANICAL AND ELECTRICAL PROBLEMS Table 2 Trouble Machine will not start/restart or repeatedly trips circuit breaker or blows fuses. 20 Probable Cause Remedy No incoming power. Verify machine is connected to power source. Make sure START button is pushed in completely, and STOP button is disengaged. Cord damaged. Replace cord. Overload automatic reset has not reset.
Miswiring of the unit. Double check to confirm all electrical connections are correct. Refer to appropriate wiring diagrams to make any needed corrections. Switch failure. If switch is suspect, you have two options: Have a qualified electrician test the switch for function, or purchase a new start switch and establish if that was the problem on changeout. Extension cord too light or too long. Replace with adequate size and length cord. Low current. Contact a qualified electrician.
15.4 WELDER MECHANICAL PROBLEMS Table 4 Trouble Probable Cause Remedy Wire connection is poor; connecting point of welding switch is bad. Change switch, or grind the connecting port with a file. Transformer burned out. Change transformer, or rewire it. Blade has oil on it. Wipe off any oil. Blade ends have rust. Grind off rust. Welding switch is cutting off late. Screw welding switch connecting nut tighter. Welding press too weak. Rotate pressure selector knob accordingly.
