ELECTRICAL SAFETY 4. Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user. 5.
12. Avoid accidental starting. Be sure the Power Switch is off before plugging in. Carrying power tools with your finger on the Power Switch, or plugging in power tools with the Power Switch on, invites accidents. 13. Remove adjusting keys or wrenches before turning the power tool on. A wrench or a key that is left attached to a rotating part of the power tool may result in personal injury. 14. Do not overreach. Keep proper footing and balance at all times.
23. Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may become hazardous when used on another tool. SERVICE 24. Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury. 25. When servicing a tool, use only identical replacement parts. Follow instructions in the “Inspection, Maintenance, And Cleaning” section of this manual.
8. Make sure the Bandsaw is located on a flat, level, sturdy surface capable of supporting the weight of the Saw and workpieces. Always “chock” the Wheels to prevent the Bandsaw from accidentally moving. 9. Make sure the Table of the Bandsaw and surrounding area are clear with the exception of the workpiece to be cut. 10. Before using the Bandsaw, check to make sure the Saw Blade is properly mounted and is not cracked or bent. 11. Industrial applications must follow OSHA guidelines. 12.
23. Never attempt to remove material stuck in the moving parts of the Bandsaw while it is plugged in and running. 24. Make sure the workpiece to be cut off has sufficient room to move sideways. Failure to do so may result in off-cut binding against the Saw Blade. 25. Always unplug the Bandsaw from its electrical outlet before performing any inspection, maintenance, or cleaning procedures. 26. Keep this product and all other tools and equipment away from children and animals.
GROUNDING WARNING! Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use.
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS 4. Tools marked “Double Insulated” do not require grounding. They have a special double insulation system which satisfies OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code. (See Figure B.) 5. Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration. (See Figure B.
7. Make sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it. 8. Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.

To Use The Quick Vise Adjustment For An Angle Cut: 1. Loosen the Hex Bolt (136), and move the Mitering Vise Plate (138) to the threaded hole position. Adjust the Mitering Vise Plate to the desired angle as indicated by the Angle Scale (165). Loosen the Hex Bolt (139), and adjust the Moveable Vise Plate (141) to parallel the Mitering Vise Plate. Then, re-tighten the Hex Bolt. (See Figure Q.
Adjusting The Blade Guide Bearings: 1. NOTE: Blade Guide Bearings (88, 92, 100, 104) adjustment is a critical factor in the performance of the Bandsaw. 2. It is always best to try a new Saw Blade (82) to see if it will correct poor cutting before attempting to adjust the Blade Guide Bearings. For example, if a Saw Blade becomes dull on one side sooner than the other, it will begin cutting crooked. A Saw Blade replacement will correct this problem, whereas Blade Guide Bearings adjustment will not. 3.
Adjusting The Blade Tracking: 1. Raise the Saw Head to its full vertical position, making sure it locks in position by turning the Support Plate (150) to the right until it firmly locks into the Body Frame (60) and inserting the Locking Pin (153). (See Figure M.) 2. Turn on the Bandsaw. The Saw Blade (82) is tracking properly when the back of the Blade is just touching the edge of the Blade Wheel (37) flange. The back of the Blade should not be rubbing against the flange. (See Figure T.) 3.

The feed rate of the Body Frame (60) can be adjusted by turning the Handle (127) clockwise to decrease the feed rate or counterclockwise to increase the feed rate. Do not turn the Handle more than one turn at a time. Excessive feed pressure can break the Saw Blade (82). Insufficient feed pressure dulls the Saw Blade rapidly. (See Figure U.
Adjusting The Blade Guide Brackets: 1. The Right Blade Guide Bracket (90) and Left Blade Guide Bracket (102) are adjustable by loosening the Guide Adjusting Knob (45) and sliding the Brackets up or down to accomodate the depth of the workpiece. (See Figure V.) 2. The Blade Guide Brackets (90, 102) should be set as close as possible to the workpiece, without interfering with the workpiece or contacting the Machine Bed (142). (See Figure V.) 3.
5. Turn the Power Switch (164) to its “ON” position. (See Figure W.) 6. CAUTION! Cut only flat workpieces when the Bandsaw is in its vertical position. Never attempt to cut pipes or other round objects with the Bandsaw in its vertical position. 7. Before cutting, turn on the Bandsaw and check for excessively loose Saw Blade (82) tension or machine vibration. If this is found, turn off the Bandsaw and correct the problem before using. (See Figure W.) 8.
14. Once the cut is made, turn the Power Switch (164) to its “OFF” position. Then, unplug the Power Cord Plug from its electrical outlet. (See Figure W.) 15. Wait until the Saw Blade (82) comes to a complete stop. Then, remove the workpiece and scrap material from the Vertical Cutting Plate (189). (See Figure W.) 16. Remove the Locking Pin (153) and turn the Support Plate (150) to the left. Then, lower the Body Frame (60) to its horizontal position. (See Figure W.
7. Turn the Power Switch (164) to its “ON” position, and slowly lower the Body Frame (60) until the Saw Blade (82) is just above the workpiece cut line. (See Figure X.) 8. Before cutting, turn on the Bandsaw and check for excessively loose Saw Blade (82) tension or machine vibration. If this is found, turn off the Bandsaw and correct the problem before using. (See Figure X.) 9. Allow the Saw Blade (82) to turn up to full speed before feeding the Saw Blade into the workpiece. (See Figure X.) 10.
damaged electrical wiring, and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, have the problem corrected before further use. Do not use damaged equipment. 3. Before each use, inspect the Saw Blade (82). Using a dull Saw Blade will cause excessive wear on the Motor of the Bandsaw and will not produce a satisfactory cut. Replace with a new Saw Blade when needed. To replace a Saw Blade: A.
E. Place the new Saw Blade (82) between each of the Guide assemblies and around the Upper Blade Wheel (37) and Lower Blade Wheel (54). IMPORTANT: The teeth must be pointing downward toward the Motor. (See Figure Y.) F. NOTE: The Bandsaw is equipped with a 64” diameter, .025” thick, 15/32” wide, 14 teeth per inch Saw Blade (82). The machine will also accept Blades in 4, 6, 8, and 10 tooth sizes. The choice of Blade pitch is determined by the thickness of the material to be cut.
E. Adjust the position of the Motor (81) to obtain approximately 1/2” depression in the V-Belt (10) when applying pressure with your thumb. (See Figure Z.) F. Tighten the Hex Bolt (70) to secure the Motor (81) in place. (See Figure X.) 5.
