Operating Manual & Safety Precautions for an Electric Pipe Threader (also known as a Pipe Threading Machine)

The Electric Pipe Threader is designed for cutting threads on steel pipes, stainless steel pipes, and conduits. It integrates pipe clamping, rotation, and thread cutting into one efficient operation.

Motor: The power source driving the rotation.

Chuck/Jaws: Clamps the pipe securely.

Die Head & Dies: The cutting tools that form the threads.

Feed Handle: Controls the forward and backward movement of the die head.

Coolant System: Pump and nozzle for applying cutting oil.

Foot Switch: Controls the motor power (On/Off).

DANGER: Failure to observe these safety rules may result in serious injury or damage to the machine.

• Grounding: Ensure the machine is properly grounded to prevent electric shock.
• Voltage: Check that the supply voltage matches the rating on the machine nameplate.
• Cables: Inspect power cables regularly. Do not use damaged cables.
• Environment: Do not operate in rain or wet conditions to avoid short circuits.

• PPE: Always wear safety goggles and protective gloves. Avoid loose clothing or jewelry that could get caught in rotating parts.
• Clamping: Ensure the pipe is clamped tightly in the chuck before starting. A loose pipe can spin dangerously.
• Guards: Never operate the machine with safety guards removed.
• Hands Clear: Keep hands away from the rotating chuck and die head.
• Stop Completely: Wait for the machine to come to a complete stop before adjusting the pipe or changing dies.

1. Check Oil: Ensure the cutting oil tank is filled with appropriate threading oil.
2. Select Dies: Install the correct dies (inserts) into the die head corresponding to the pipe size and standard (e.g., NPT, BSP, Metric).
3. Mount Pipe: Insert the pipe into the chuck.
4. Note: The pipe end should protrude slightly (approx. 15-20mm) from the chuck to allow for threading.

5. Tighten the chuck handle to secure the pipe.
6. Ensure the pipe is held firmly and does not wobble.

7. Adjust the Feed Handle to move the die head close to the pipe end.
8. Set the Thread Length Indicator to the desired length.

9. Start Coolant: Turn on the coolant pump to ensure oil flows onto the die and pipe.
10. Activate Motor: Press the Foot Switch to start the motor (usually rotates counter-clockwise for threading).
11. Engage Cut: Slowly pull the Feed Handle forward. The dies will contact the pipe and begin cutting.
12. Tip: Apply steady, gentle pressure. Do not force the handle.
13. Automatic Stop: On many models, the machine will automatically reverse or stop when the desired thread length is reached. If manual, release the foot switch immediately after the cut is complete.

14. If the machine does not auto-reverse, press the "Reverse" button or switch to pull the die head back away from the pipe.
15. Wait for the rotation to stop completely.

16. Loosen the chuck and remove the threaded pipe.
17. Clean the dies and the machine of metal shavings (swarf).

• Lubrication: Grease the chuck and moving parts regularly.
• Cleaning: Clean the coolant tank and filter periodically to remove metal chips.
• Brushes: Check carbon brushes every 6 months; replace if worn.
