Setup
- Unpack the Set: Carefully remove all components from the packaging. Verify that all parts are present according to the packing list (if provided).
- Inspect Components: Check all parts for any signs of damage from shipping. Do not use damaged components.
- Familiarize Yourself: Identify the flaring cone, clamping bar, and the various pipe dies. Understand how they fit together.
Operating Instructions
Follow these steps for proper pipe flaring:
- Prepare the Pipe: Cut the pipe to the desired length and ensure the end is clean, smooth, and free of burrs. Use a reamer to deburr the inside edge if necessary.
- Select the Correct Die: Choose the appropriate die from the set that matches the outer diameter of your pipe (e.g., 3mm, 19mm).
- Clamp the Pipe: Insert the pipe into the selected die opening on the clamping bar. Position the pipe so that the end extends slightly above the surface of the clamping bar (typically about 1/16 to 1/8 inch or 1.5 to 3 mm), depending on the desired flare size. Securely tighten the clamping bar screws to hold the pipe firmly in place.
- Position the Flaring Cone: Place the flaring cone assembly over the clamped pipe, ensuring the cone is centered over the pipe opening.
- Flare the Pipe: Slowly turn the handle of the flaring cone assembly clockwise. This will push the cone into the pipe opening, gradually expanding and forming the flare. Continue turning until the flare is fully formed and makes contact with the clamping bar surface. Do not overtighten.
- Remove the Flared Pipe: Unscrew the flaring cone assembly, then loosen the clamping bar screws and carefully remove the flared pipe.
- Inspect the Flare: Check the flare for uniformity, cracks, or imperfections. A properly formed flare should be smooth and even.
Maintenance
- Cleaning: After each use, wipe down the tool with a clean, dry cloth to remove any debris or residue.
- Lubrication: Periodically apply a light coat of machine oil to the threads of the flaring cone assembly to ensure smooth operation and prevent rust.
- Storage: Store the PROLINE Pipe Spreading Set in its original case or a suitable toolbox in a dry environment to protect it from moisture and dust.
- Inspection: Regularly inspect all components for wear, damage, or deformation. Replace any worn or damaged parts immediately.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven or cracked flare | Pipe not deburred; pipe not clamped securely; overtightening; incorrect pipe extension. | Deburr pipe end; ensure pipe is clamped tightly; avoid overtightening; adjust pipe extension. |
| Difficulty turning flaring cone | Lack of lubrication; damaged threads. | Apply lubricant to threads; inspect for damage and replace if necessary. |
| Pipe slips during flaring | Clamping bar not tightened enough; incorrect die size. | Ensure clamping bar screws are fully tightened; verify correct die size for pipe. |
