Frequently Asked Questions - 300 Compact RIDGID

How to change the dies on the quick-opening die head?
Place the head with the numbers facing up. Open the stop lever, loosen the locking lever about three turns, remove the washer, then replace the dies by aligning the numbers. Close and tighten the lever.
Why won't my machine rotate?
Check that the switch is in the FWD position and the foot pedal is depressed. If the motor does not start, the carbon brushes may be worn (replace if they measure less than 12.7 mm). Also ensure the machine is plugged in.
How to adjust the cutting oil flow?
Turn the knob on the carriage: clockwise to decrease flow, counterclockwise to increase. Never adjust the setting while threading.
Which cutting oil to use?
Use only RIDGID cutting oil for quality threads and optimal die life. Do not use other oils.
How to replace the cutting roller?
Push the roller axle to extract it from the frame. Replace the axle and roller with genuine RIDGID parts, lubricating with light oil.
Can I thread pipes already assembled with fittings?
No, do not attempt to thread pipes with fittings or accessories attached. This increases the risk of entanglement. Always remove fittings beforehand.
How to adjust the thread length on the 728/928 retractable die head?
Loosen the lower release screw and slide the release to adjust length (factory marks). Tighten the screw after adjustment.
What to do in case of torn or poor-quality threads?
Check the condition of the dies (replace if damaged), oil flow (increase it), and oil cleanliness. Also ensure the die head is properly aligned and the pipe is suitable (black or galvanized steel schedule 40).
How to safely transport the machine?
Set the switch to OFF and unplug. Empty the chip drawer, fold down the pipe cutter, reamer, and die head. Wrap the cords and use the carrying handles. Weight: 64 kg.
Where to find spare parts?
Consult the RIDGID catalog online or contact an authorized RIDGID service center. Use only genuine RIDGID parts for safety and proper operation.
