and replace the guards immediately after completion of maintenance. 14. Check damaged parts. Before further use of the machine, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced. 1.

1 subject to local and national electrical codes 2 The specified values are emission levels and are not necessarily to be seen as safe operating levels. As workplace conditions vary, this information is intended to allow the user to make a better estimation of the hazards and risks involved only. L = length, W = width, H = height n/a = not applicable 4.
Read and understand all assembly instructions before attempting assembly. Failure to comply may cause serious injury. 5.0 Setup and assembly Disconnect band saw from power during setup. 5.1 Shipping contents 1 1 5. Adjust leveling screws until machine is level in both directions and tighten nuts against the base flanges. 6. Remove braces holding control box, and mount control box directly to bow, using the existing screws and washers. 7.
Before connecting to power source, be sure switch is in off position. 6.1 GROUNDING INSTRUCTIONS This tool must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug.
7.2 Bracket adjustment 7.0 Adjustments The blade guide brackets (F, Figure 7-1) must be set to just clear the workpiece, but should not interfere with workpiece or other saw components during bow’s descent. Disconnect machine from power source before making adjustments, unless indicated otherwise. Loosen knobs and slide brackets into position. Always tighten knobs before operating machine. 7.1 Blade installation and removal Refer to Figure 7-1. 7.
6. If tension mechanism will not move blade, loosen and then re-tighten socket head cap screws on gibs (X, Figure 7-3). 7.4.2 Tracking Tracking is performed with wheel covers open and blade moving. Use extreme caution so that you do not come into contact with blade. Keep fingers clear of blade and wheel to avoid injury. 7. Turn single hex adjustment screw (M1) to stop motion of blade on wheel as it gets closer to wheel shoulder. Put a 6-inch length of paper between blade and wheel.
3. Push down lever (W) all the way until it locks into position. If lever will not push all the way down or does not have sufficient tightness to secure bow, adjust screw beneath lever (W1). Figure 7-4: belt de-tensioning Figure 7-7: bow swivel adjustment Figure 7-5: belt positioning 7.6 Vise adjustment Refer to Figure 7-6. Figure 7-8: bow locking lever The workpiece is placed between the vise jaws with required amount to be cut-off extending past the blade. 7.8 Material stop Refer to Figure 7-9.
7.9 Coolant flow 9.0 Operation Coolant pump must be submerged before operating to prevent damage to pump. 9.1 Automatic shut-off The blade guides are fitted with coolant valves. Coolant is provided to the fittings through interconnecting tubing, and is dispensed directly onto saw blade. The machine and any accessories which are wired into the electrical system are controlled by the startstop buttons. Saw will automatically shut off when cut is completed.
4. Select proper speed and feed rate for material being cut. 5. Material to be cut must be securely held in vise. 6. Check to see that coolant level is adequate and turn on coolant pump if material to be cut requires it. Machine should be filled with approximately 15 L (4 gal.) of proper coolant mixture. Follow directions on product maker’s label and fill coolant tank through chip tray area. 7. Do not start cut on a sharp edge. 8. Keep machine lubricated. See sect. 10.2. 9.
Coolant – Maintain proper coolant level. Clean chip sludge from coolant tank and hose as needed. Replace coolant on a frequency appropriate to type of coolant being used. Oil-based coolants can sour. Refer to coolant supplier’s instructions for frequency. 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.
10.4 Additional servicing Any additional servicing should be performed by authorized service personnel. 11.0 Troubleshooting MBS-1018 Band Saw Symptom Excessive blade breakage Possible Cause Correction* Material loose in vise. Clamp work securely. Incorrect speed or feed. Check machinery handbook for speed/ feed appropriate for material being cut. Teeth too coarse for material. Check machinery handbook recommended blade type. Incorrect blade tension.
Symptom Bad cuts (rough) Blade is twisting Unusual wear on side or back of blade Possible Cause Correction* Blade speed too high for feed pressure. Reduce blade speed and feed pressure. Blade too coarse. Replace with finer blade. Blade is binding in the cut. Decrease feed pressure. Blade tension too high. Decrease tension on blade Blade guides worn Replace blade guides. Blade guide bearings not adjusted. Adjust blade guide bearings. Blade guide bearing bracket is loose.
