| Асуудал | Боломжит шалтгаан | Шийдэл |
|---|---|---|
| Mandrel stops or encounters high resistance. | Severe obstruction in the duct (e.g., large rock, collapsed section). | Stop pulling immediately. Attempt to pull the mandrel back. If unable to retrieve, further investigation of the duct is required to identify and remove the obstruction. Do not force the pull. |
| Mandrel appears damaged after use. | Excessive force applied, sharp edges in duct, or material fatigue. | Inspect for specific damage. If significant, replace the mandrel. Review operating procedures to ensure proper use and avoid exceeding force limits. |
| Mandrel does not clear all debris. | Very sticky mud or compacted debris. | Perform multiple passes. Consider using a duct brush or other cleaning tools before the mandrel for heavily soiled ducts. |
