Threading Operation Procedure
1. Position cutting knife frame and chamferer; lower die head to contact copying block. Secure die head positioning and activate machine.
2. Rotate pipe counter-clockwise while turning cutting feed hand wheel to advance die head toward pipe.
3. Apply pressure to cutting feed hand wheel until die head creates 3-4 threads on pipe.
4. Release hand wheel for automatic threading. When die head roller passes copying block, threading die opens automatically. Machine reverses to exit threading die.
5. Stop machine, return carriage until die head fully exits pipe, then lock handle and raise die head.
Troubleshooting Guide
Problem Cause Solution
Motor doesn't work or has intermittent sound Fuse failure, connection issues, capacitor breakdown, or low temperature Check electrical components with multimeter, replace faulty parts, operate indoors
Pipe slips during threading Insufficient hammering force or damaged clamping jaw Increase hammering force or replace clamping jaw tip
Cutting knife fails to produce proper threads Worn cutting knife blade or insufficient cutting force Replace cutting knife components or apply more cutting force
Knife cannot cut during threading Improper die opening, broken teeth, or debris in die groove Correct die usage, replace damaged components, clean die head
Cooling oil doesn't circulate Clogged oil line, misaligned oil hole, or worn oil pump Clean oil lines, realign components, or replace oil pump
