• Use proper lifting practices when lifting the bender. result in severe injury or death. The bender weighs over 75 lb (34 kg), and requires more than one person to lift. Failure to observe these precautions may result in injury. Do not leave the ratchet handle in the UP position when the bender is not in use. A handle left in the UP position could fall unexpectedly. Use this product for the manufacturer’s intended purpose only. Use other than that which is described in this manual may result in injury or property damage.

9. rise — the distance from the end of a straight section of conduit or pipe to the bend; measured from the end to the center line of the conduit or pipe. Also called stub or stub-up. 10. saddle — a three-bend or four-bend combination; used to avoid an obstruction. 11. shrink — the amount of conduit “lost” when laying out an offset bend working toward an obstruction. 12. springback — the amount, measured in degrees, that a conduit or pipe tends to straighten after being bent.

START OF FIRST BEND LENGTH LENGTH – X HEIGHT ANGLE BENDING BENDING MARK 1 MARK 2 1. Select the size and type of conduit. Measure the height of the obstruction and the distance labeled LENGTH. Determine the angle to be used. 2. Find the chart that corresponds to the size of conduit selected in Step 1. 3. To the right of the size and type of conduit, find the dimension labeled X. Subtract X from LENGTH. Place the first bending mark this distance from the end of the conduit. 4. Under the column labeled ANGLE, find the angle of bend. Find the intersection of the L1 row and the appropriate HEIGHT column. The number at this intersection is the dimension L1. Place the second bending mark L1 inches from the first bending mark. 5. See the Operation section of this manual. Greenlee / A Textron Company 4455 Boeing Dr. • Rockford, IL 61109-2988 USA • 815-397-7070... - Page 9 1. Select the size and type of conduit. Measure the height of the obstruction and the distance labeled LENGTH TO CENTER. Determine the angle to be used. 2. Find the chart that corresponds to the size of conduit selected in Step 1. 3. Under the column labeled ANGLE, find the angle of bend needed. Find the intersection of the Z row and the appropriate HEIGHT column. The number at this intersection is the dimension Z. Subtract Z from the LENGTH TO CENTER. Place the first bending mark here. 4. In the same column, find the row labeled L1. Place the second bending mark L1 inches from the first bending mark. 5. In the same column, find the row labeled L2. Place the third bending mark L2 inches from the second bending mark. 6. See the Operation section of this manual. Note: The second bend angle will be twice the number of degrees as the first and third bends. Greenlee / A Textron Company 4455 Boeing Dr. • Rockford, IL 61109-2988 USA • 815-397-7070...

Add L2 to the STRAIGHT SECTION. Place the third bending mark this distance from the first bending mark. 6. Make the final bending mark L1 inches from the third bending mark. 7. See the Operation section of this manual. U-Bends LENGTH HEIGHT BENDING BENDING MARK 1 MARK 2 1. Select the size and type of conduit. Determine the LENGTH and the HEIGHT. 2. Find the chart that corresponds to the size of conduit selected in Step 1. 3. Under the column labeled ANGLE, find 90°. Find the intersection of the Y row and the HEIGHT column that cor- responds to the dimension labeled LENGTH in the illustration. Place the first bending mark Y inches from the end of the conduit. 4. Find intersection of the L1 row and the HEIGHT column that corresponds to the dimension labeled HEIGHT in the illustration. Place the second bending mark L1 inches from the first mark. 5. See the Operation section of this manual. Greenlee / A Textron Company 4455 Boeing Dr. • Rockford, IL 61109-2988 USA • 815-397-7070...
