Mastercool 70070-m ratchet crossbow style metric tube bender kit

Hand-operated ratchet design bends tubes easily bends: 8, 10, 12, 14, 16, 18 & 22mm o.D. Soft tubing. Soft tubing. Includes heavy duty tube cutter for. Includes inner-outer reamer. Comes in custom molded case

Setup and operation instructions.

Note: tube sizes are outside diameters!
1) choose the cross bar (6) that corresponds to the tubing size that you are going to bend. Install the cross bar in the mainframe (4) slot and tighten wing nut.
2) select the proper size radius block (2) and assemble to the tooth ratchet (3). Press the radius block onto the square end of the tooth ratchet.
3) set support blocks so that the proper diameter dimensions face the tubing. Make sure both blocks have the same diameter showing. Place tube between support blocks and radius block. Start to squeeze ratchet handle. The tube will advance into the radius block. Continue operating the ratchet handle until tube is bent to desired angle. To ensure an accurate 90 degree angle, use a "square".
4) to remove tube, pull back radius block by pushing ratchet handle away from the mainframe and hold in place. Push tubing and radius block towards the ratchet handle. Pull tube out of radius block and check the angle of the tube bend using a "square" or protractor.
5) radius block is removed from the ratchet bar by "wiggling" and pulling block away from the toothed ratchet.

Safety requirements.

Use only soft copper tubing with this bender.
Always use personnel safety equipment (i.E. Safety glasses, gloves, etc.)
Only personnel knowledgeable in the use of tube benders should use this tool.
Keep bender dry and lubricate ratchet mechanism.
Making 90 degree offset bends

1) mark the required length from the end of the tubing.
2) place the tube in the radius block with the measured mark aligned with a raised guide line 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 guide line. If the measured end of the tube is on the left side of the bender, use the raised right side guide line.
