Specification: ?Item Type: Tube Bender Material: Aluminium Alloy Color: Blue Bending radius: 0-120 Reference mark: 45-90 Application: Suitable for small pipes of 1/8 inch (3mm), 3/16 inch (4mm), 1/4 inch (6mm), such as automobile fuel pipes and air conditioning refrigerant pipes. It is also suitable for bending round copper tubes, aluminum tubes and copper tubes. How to Use: 1. Raise the handle of the pipe bander and position tubing in the correct channel size. Be sure the top surface of the tubing makes contact with the support(Fig 1). 2. Mark on the pipe where you needthe bend, making sure"0"on the handle is in line with o, slowly lower the handle until the "o"aligns with the desired angle (Fig 2 shows the position for a 45 angle, Fig3 shows a 90 angle). 3. If you need the bend to be to the left of the marked position, align the mark on the pipe to "L", and repeatthe motion needed to bend the pipe. right of the mark, position the mark on the pipe to "R" PackageList: 1 x Tube Bender
