SAFETY REQUIREMENTS
- Use only soft copper tubing with this bender.
- Always use personal safety equipment (i.e. safety glasses, gloves, etc.)
- Only personnel knowledgeable in the use of tube benders should use this tool.
- Keep the bender dry and lubricate the ratchet mechanism.

SETUP AND OPERATION INSTRUCTIONS
NOTE: Tube sizes are outside diameters!
- Choose the crossbar (6) that corresponds to the tubing size that you are going to bend. Install the crossbar in the mainframe (4) slot and tighten the wing nut.
- Select the proper size radius block (2) and assemble it to the toothed ratchet (3). Press the radius block onto the square end of the toothed ratchet.
- Set support blocks so that the proper diameter dimensions face the tubing. Make sure both blocks have the same diameter showing. Place the tube between the support blocks and the radius block. Start to squeeze the ratchet handle (5). The tube will advance into the radius block. Continue operating the ratchet handle until the tube is bent to the desired angle. To ensure an accurate 90-degree angle, use a “square”.
- To remove the tube, pull back the radius block by pushing the ratchet handle away from the mainframe and HOLD in place. Push tubing and radius block towards the ratchet handle. Pull the tube out of the radius block and check the angle of the tube bend using a “square” or protractor.
- The radius block is removed from the ratchet bar by “wiggling” and pulling the block away from the toothed ratchet.
MAKING 90˚ OFFSET BENDS
- Mark the required length from the end of the tubing.
- Place the tube in the radius block (2) with the measured mark aligned with a raised guideline on the face of the radius block. If the measured end of the tube is on the right side of the bender, use the raised left-side guideline. If the measured end of the tube is on the left side of the bender, use the raised right-side guide line.
SETUP INSTRUCTIONS FOR REVERSE DIRECTION BENDING ADAPTER (70070-RD)
BENDS: 1/4”, 5/16”, 3/8”, 1/2”, 5/8”, 3/4”, 7/8” O.D. TUBING
- Attach adapter (3-1) to bar on a bender. Tighten the wing nut.
- Install adapter (3-2) on the bender body and tighten the wing nut.
- Install desired crossbar and radius block (3-3) in the usual way.
