This tool is prewired 230-volt, and is intended for use on a circuit that has an outlet that looks like the one illustrated in Figure 9-1. The tool is intended for use with a grounding plug that looks like the plug illustrated in Figure 9-1. 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.
7.0 Adjustments Disconnect machine from power source before making adjustments, unless indicated otherwise. 7.1 Blade installation and removal Refer to Figure 7-1. Always wear leather gloves when handling blades to avoid injury. Figure 7-1: blade changing A blade (1-1/4 in. W x 172 in. L) is pre-installed and tensioned on saw. To replace blade: 7.2 Guide post adjustment 1. Raise bow about 15-degrees and keep it in raised position by turning feed rate control knob clockwise all the way (see sect. 8.0).
Figure 7-4: blade tension and tracking Figure 7-3: carbide guide adjustment While performing the following, keep blade from excessively rubbing on wheel shoulder, which may damage wheel and/or blade. 7.4 Blade tension and tracking Refer to Figure 7-4. 7.4.1 Tension 5. Blade tension has been set by manufacturer at approximately 1800 kg/cm2 (25,000 psi) for the supplied blade. Turn handwheel (C, Figure 7-4) clockwise; if collar (N) slips out of position, then blade is properly tensioned.
. Hold hex adjustment screws (P, P1) with a wrench and tighten center locking screws (O). Make sure hex adjustment screws do not move while tightening center screws. 12. Adjust left and right bearing guide assemblies. See sect. 7-3. 13. Install left blade guard and close wheel cover. 7.5 Belt tension Refer to Figure 7-5. 1. Disconnect machine from power source. 2. Open pulley cover (R, Figure 7-5). 3. Loosen knob (S) and lift handle upward (T) to tension belt. 4. Retighten knob (S).
Figure 8-1: control panel Figure 7-9: bow locking lever Feed rate control (A) – Sets amount of downward force that is applied to saw blade. The feed rate is proportional to opening of valve. Increasing valve opening (counterclockwise) increases feed rate; decreasing valve opening (clockwise) reduces feed rate. When set to zero, bow is locked in raised position. 7.8 Material stop Refer to Figure 7-10. The material stop is generally used when cutting multiple pieces to the same length.
9.4 General operating procedure All blade covers and machine guards must be in place and secured before turning on band saw. 1. Select proper speed on digital readout for type of material to be cut. 2. Raise bow high enough to clear workpiece. Make sure blade is not in contact with workpiece when motor is started. Figure 9-1: auto shut-off switch 9.1.2 Blade breakage 3. Place stock between vise jaws, set stock for desired width of cut and tighten vise.
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.
should be drained and refilled. After that change oil every six months. 10.0 User-maintenance Always disconnect power to machine before performing maintenance.

Remove oil fill plug (B) and fill gearbox with 1 liter (1 qt.) of MobilTM SHC 634 gearbox oil, or equivalent. Replace fill plug.
12.0 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. Check machinery handbook for recommended blade type. Adjust blade tension to the point where the blade just does not slip on the wheel. Start the motor before placing the saw on the workpiece. Adjust blade tracking. Teeth too coarse for material.
Symptom Unusual wear on side or back of blade Possible Cause Correction* Blade guides worn Replace blade guides. Blade guide bearings not adjusted. Adjust blade guide bearings. Blade guide bearing bracket is loose. Tighten blade guide bearing bracket. Teeth missing/ripped from blade Blade tooth pitch too coarse for workpiece. Feed too slow; feed too fast. Workpiece vibrating. Gullets loading up with chips.
