Key Components:
- Adjustment Knob: Used to open and close the jaws and apply pressure to the cutting wheel.
- Cutting Wheel: The sharp blade that scores and cuts the pipe.
- Rollers: Support the pipe and allow it to rotate smoothly during cutting.
- Retractable Deburrer: A small blade used to remove internal burrs from the cut pipe end.
Setup
- Inspect the Tool: Before each use, check the cutting wheel for sharpness and ensure all components are free from damage or excessive wear.
- Prepare the Pipe: Mark the desired cut line on the pipe. Ensure the pipe surface is clean and free of obstructions.
- Adjust Jaw Opening: Rotate the adjustment knob counter-clockwise to open the pipe cutter jaws wide enough to fit over the pipe.
Operating Instructions
- Position the Pipe: Place the pipe between the rollers and the cutting wheel, aligning the marked cut line with the cutting wheel.
- Initial Tightening: Rotate the adjustment knob clockwise until the cutting wheel makes light contact with the pipe. Do not overtighten.
- First Rotation: Rotate the pipe cutter completely around the pipe, ensuring the cutting wheel scores the pipe evenly along the marked line.
- Gradual Tightening and Rotation: After each full rotation, tighten the adjustment knob slightly (about a quarter to half turn) to apply more pressure to the cutting wheel. Continue rotating the cutter around the pipe and tightening gradually.
- Complete the Cut: Repeat the tightening and rotating process until the pipe is cleanly cut through. A clean cut requires patience and gradual pressure.
- Remove the Pipe: Once the cut is complete, rotate the adjustment knob counter-clockwise to release the pipe.
- Deburring (Optional): Extend the retractable deburrer blade. Insert it into the freshly cut end of the pipe and rotate it to remove any internal burrs, ensuring a smooth flow and proper fitting.
Maintenance
- Cleaning: After each use, wipe down the pipe cutter with a clean, dry cloth to remove any metal shavings or debris.
- Lubrication: Periodically apply a light oil to the adjustment screw threads and rollers to ensure smooth operation.
- Cutting Wheel Replacement: If the cutting wheel becomes dull or chipped, it should be replaced. Consult a qualified technician or refer to specific replacement instructions for your model.
- Storage: Store the tool in a dry environment to prevent rust and corrosion.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven or crooked cut | Pipe not properly aligned; uneven pressure applied; cutting wheel dull. | Ensure pipe is square to the cutter. Apply even pressure. Replace cutting wheel if dull. |
| Difficulty cutting through pipe | Insufficient pressure; dull cutting wheel; attempting to cut material beyond capacity. | Apply more gradual pressure. Replace cutting wheel. Verify pipe material is within tool's capacity. |
| Excessive burr on pipe interior | Deburrer not used or ineffective. | Utilize the retractable deburrer after cutting. Ensure deburrer blade is sharp. |
| Adjustment knob stiff or difficult to turn | Lack of lubrication; debris in threads. | Clean threads and apply light lubricant. |
