ELECTRICAL SAFETY 1. 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. 2.
4. 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. 5. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the power tool in unexpected situations. 6. Use safety equipment. Always wear eye protection. Dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.
Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electric shock or injury. SPECIFIC SAFETY RULES 1. Maintain labels and nameplates on the Bandsaw. These carry important information. If unreadable or missing, contact Harbor Freight Tools for a replacement. 2. Always wear safety impact eye goggles and heavy work gloves when using the Bandsaw. Using personal safety devices reduce the risk for injury.
14. Never attempt to cut freehand. Make sure the workpiece to be cut is pressed firmly against the Table and/or secured in the Vise. 15. When cutting a large workpiece, make sure its entire length is properly supported. If necessary, use a roller stand (not included). 16. Do not lean on the Bandsaw when the tool is in its upright position. 17. When moving the Bandsaw, always have its Head lowered to its horizontal position. 18.

OPERATING INSTRUCTIONS WARNING! Always make sure the Toggle Switch (37) for the Bandsaw and the Toggle Switch (11) for the Coolant Pump are both in their “OFF” position and the tool is unplugged from its electrical outlet prior to making adjustments to the tool. Selecting Proper Blade Speeds: When using the Bandsaw always change the blade speed to best suit the material being cut. The Blade Speed Chart illustrates several settings for several types of materials. (See Figure K.
Adjusting The Quick Vise For An Angle Cut: Loosen the three Screws (99). Adjust the Rear Vise (95) to the threaded hole position. Set the Scale (100) to the desired angle. Adjust the Front Vise (94) to parallel the Rear Vise. Then, retighten the three Screws. (See Figure M.) SCREW (99) REAR VISE (95) SCREW (99) FIGURE M SCREW TABLE (39) SCALE (99) (100) FRONT VISE (94) THREADED HOLE Adjusting The Stop Block: 1. Loosen the Thumb Screw (72) that holds the Stop Block (73) to the Stock Stop Rod (74).
Converting The Bandsaw For Vertical Use: 1. NOTE: Notching, slitting, and contour work is best done with the Bandsaw in its vertical position. 2. Raise the Saw Head to its full vertical position, making sure it locks in position by turning the Hydraulic Cylinder (20) to its “OFF” position. (See Figure O.) 3. Remove the two Screws (141), and remove the Small Vertical Cutting Plate (142). (See Figure P.) 4.

BLADE TENSION KNOB (181) WHEEL (175) UPPER SCREW (168) BLADE BACK COVER (128) ADJUSTING SCREW (168) FIGURE R Adjusting The Blade Tension: 1. Turn the Blade Tension Knob (181) clockwise to increase tension on the Saw Blade (127). Turn the Blade Tension Knob counterclockwise to decrease tension on the Saw Blade. Correct tension is acquired when the Saw Blade is just tight enough so that no slippage occurs between the Saw Blade and the Wheels (124, 175). 2.
Adjusting The Blade Guide Brackets: 1. The Right Adjustable Bracket (132) and Left Adjustable Bracket (163) are adjustable by loosening the two Guide Adjusting Knobs (131) and sliding the Brackets to accommodate the width of the workpiece. (See Figure T.) 2. The Blade Guide Brackets (132, 163) should be set as close as possible to the workpiece, without interfering with the workpiece or contacting the Table (39). (See Figure T.) 3.
(See Figure U.) 5. Turn the Coolant Pump Valve (159) to its “OPEN” position. Then, turn the Coolant Pump Toggle Switch (11) to its “ON” position. (See Figure U.) 6. Turn the Motor Toggle Switch (37) to its “ON” position. (See Figure U.) 7. WARNING! 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. 8.
10. When cutting a large workpiece, make sure its entire length is properly supported. If necessary, use a roller stand (not included) with a larger workpiece. 11. Allow the Saw Blade (127) to turn up to full speed before feeding the workpiece into the Saw Blade. (See Figure U.) 12. WARNING! Always keep hands and fingers safely away from the cutting area. 13. Feed the workpiece into the Saw Blade (127) gradually. Do not force the Bandsaw to remove material faster than it is designed to cut.
6. Once all necessary adjustments to the Bandsaw have been made, plug the Power Cord Plug (38) into the nearest 120 volt, grounded, electrical outlet (if the Bandsaw is powered by a 120 volt system). If powered by a 230 volt system, plug the Power Cord Plug into the nearest 230 volt, grounded, electrical outlet. (See Figure V.) 7. Turn the Hydraulic Cylinder (20) to its “ON” position, and slowly allow the Saw Head to lower until the Saw Blade (127) is just above the workpiece cut line.
automatically lower on its own, while it gradually feeds the Saw Blade (127) into the workpiece. Do not force the Bandsaw to remove material faster than it is designed to cut. NOTE: The speed at which the Saw Arm moves downward may be increased or decreased by adjusting the valve on the Hydraulic Cylinder (20). (See Figure V.) 14. Never attempt to remove material stuck in the moving parts of the Bandsaw while it is plugged in and running.
3. Before each use, inspect the Saw Blade (127). 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. NOTE: Make sure to wear heavy duty work gloves to avoid accidental cuts from the Saw Blade (127) when performing this procedure. b. Turn the Hydraulic Cylinder (20) to its “ON” position, and raise the Saw Head to its full vertical position.
g. NOTE: The Bandsaw is equipped with a 93” diameter, .032” thick, 3/4” wide, 8 tooth per inch Saw Blade (127). 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. The thinner the workpiece, the more teeth is recommended. A minimum of 3 teeth should engage the workpiece at all times for proper cutting.
5. To lubricate the Worm Gear and Worm Shaft: The Worm Gear (116) and Worm Shaft (203) run in an oil bath Gear Box (121) and should not require an oil change more than once a year, unless the oil becomes contaminated or a leak occurs due to improper replacement of the Gear Box Cover (114). To change oil in the Gear Box: a. Position the Saw Arm in the horizontal position. (See Figure V.) b. Remove the four Screws (112), Gear Box Cover (114), and Gear Box Gasket (115). (See Figure Y.) c.
b. Remove the white lid at the top of the Coolant Tank (107), and dispose of the old Coolant properly in a container. (See Figure Z.) c.
