Q8:What is complete test‑running operating procedure for A‑292 Automatic Cement Insole Folding Machine?

A8:

1.Check oil level sight glass, ensure oil level reaches central red dot; fill 40# machine oil if insufficient. Run machine idle for about 1 minute after oil filling.
2.Connect 220V power and turn on main power switch. Enable glue‑box heating and presser‑foot heating switch.
3.Wait about 12 minutes until actual temperature approaches set‑point, then turn on glue output switch.
4.Set glue‑box temperature, presser‑foot temperature, glue flow rate and running speed according to leather material. Adjust clearance of hammer, presser foot, baffle and cutter bar.
5.Test with sample leather. Press right pedal for normal folding; press left pedal for toothing when processing inner curve. Reduce speed for small‑radius corner work.
6.Start mass‑production only after sample test passes.
7.Turn off heating and glue‑output after work, clean and maintain machine.

Q9:What precautions for temperature and glue‑output adjustment?

A9:Factory default temperature for glue‑box and presser foot is 140℃. Glue output can only be enabled after full heating. Recommended glue‑flow setting: 2‑6. Suggested glue‑box temperature range 130‑150℃. Excessive temperature will deteriorate hot‑melt glue; clean glue‑box filter and impurities periodically.
