SPECIFIC SAFETY PRECAUTIONS

WARNING! DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to the tool safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.

1. Use the correct tool for the job. This tool was designed for a specific function. Do not modify or alter this tool or use it for an unintended purpose.
2. Do not use the tool if any parts are damaged, broken or misplaced. Repair or replace the parts.
3. Check to ensure that all applicable bolts and nuts are firmly tightened.
4. Place the tube bender on a solid, level surface capable of supporting the weight of the tube bender and workpiece. Secure the tube bender with bolts.
5. The tool will have force applied to it. The object that the tool is bolted to must have enough weight to avoid moving when pressure is applied.
6. Only use accessories rated to handle the forces exerted by this tool during operation. Other accessories may break and forcefully launch debris into the work area.
7. Sharp edges or burrs may develop during the bending process. Wear heavy gloves to protect the hands.
8. Keep hands and fingers away from the active parts of the tool while bending to avoid a pinch or crush injury.

UNPACKING
WARNING! Do not operate the tool if any part is missing. Replace the missing part before operating. Failure to do so could result in a malfunction and personal injury.
Remove the parts and accessories from the packaging and inspect for damage. Make sure that all items in the parts list are included.

ASSEMBLY & INSTALLATION

Numbered references in parenthesis (#1) refer to the included Parts List.

1. Mount the handwheel (#17) onto the driving shaft (#18). Secure the wheel in place using a bolt (#26). Be sure handwheel and driving shaft turn freely, then tighten bolt (#26) securely.
2. Before use, the correct size rollers must be installed. Pull the spring clip (#4) from the shafts (#10, #15 and #18), remove the washers (#2) and pull the shafts out of the rollers (#10, #15 and #18).
3. Select the correct rollers to match the diameter tubing you will be bending. If your tubing does not match the exact size of the available rollers, use the roller size just larger in diameter than the tubing material.
4. Install the rollers by inserting the shafts (#10, #15 and #18), being sure the washers (#2) are in place. Refer to the assembly diagram at the end of this manual for correct assembly. Fix the shafts in place using the spring clips (#4).

MOUNT TOOL ON A WOOD WORKBENCH

The hardware to mount the tool is not included.

1. Clean the work area where the tool will be mounted.
2. Position the tool, check that it will be level and there are no obstructions around it that will interfere with a long workpiece.
3. Slide a flat washer over a 1/4 x 1 in. wood screw and secure the grinder in place.
4. repeat with three more screws. Tighten all screws until the gap between the grinder base and the bench-top is 1/8 in.

OPERATION

• This tool is intended to bend mild steel, copper and aluminum tubing. It can be used for bending exhaust pipe, water pipe and electrical conduit. Do not bend plastic or PVC pipe with this tool.
• This tool includes three sets of rollers: small, medium and large.
• The minimum practical bend radius for any tube varies with the diameter and wall thickness of the tube. Extra-heavy tubes can be bent to a smaller radius than thinner wall tubes of the same diameter. In general, tubes of standard wall thickness should not be bent to a radius less than 5 to 6 times the nominal tube diameter.
  Tubing Diameter| Tubing Diameter
  ---|---
  1 in.| 5 in.
  1-1/2 in.| 7-1/2 in.
  2 in.| 10 in.
  1. Place a wrench on the hex portion of the adjustment bolt (#8) and turn counterclockwise raising the upper die.
  2. After raising the bottom edge of the upper die above the top edges of the drive roller dies, place your piece of tubing into the machined cutouts of the roller dies until it is contacting all three roller dies then tighten the adjustment bolt (#8) down 1/4 turn to put light pressure on the tubing.
  3. Facing the handwheel, begin forming by feeding your tubing into the left side of the machine while turning the handwheel to the right and tightening down gently with the adjustment bolt (#8).
  4. When creating tighter radii (such as the handwheel from this device), you may need to spiral your work slightly to clear the body of the machine. This can easily be flattened after completion.

CHANGING ROLLER DIES

1. Using a wrench, loosen and remove the Bolt (#26) and Handwheel(17) from the Driving Shaft (#18).

2. With a hex key, loosen the set screws (#29) on the Chain Wheel (#21), then pull the Chain Wheel (#21) and Chain (#20) off the Driving Shaft (#18).

3. Using a hex key, loosen & remove the two Screws (#5) at the top face of the Side Plate (#1).

4. Unbolt the entire unit from the mounting surface and turn the unit on
   its side.

5. Using a hex key, loosen & remove the screws (#23) (closest to the driveshaft side) attaching the Base (#7) to the Lower Roller Plate (#12).

6. stand unit up on the Base (#7) and remove the two large Spring Clips (#4) and washers (#2) from the Shafts (#10).

7. Pull the Side Plate (#1) out and over the Shaft (#10) and put it aside.

8. Carefully withdraw the center roller die Shaft (#10) by pulling it through the upper roller die and opposite side plate while removing the upper roller die with your opposite hand.

9. Pull the left roller die and Driven Shaft (#15) from the Lower Roller Plate (#12) then pull the Driving Shaft (#18) from the Lower Roller Plate (#12) and place them in a safe location.

10. You are now ready to install the size of your choice.

11. Reassemble.
