Scope and common interpretation errors
For manual or mechanical trimming, without approving unauthorized filler repairs.
Blade condition, positioning and direction affect cuts. Cutting stretched rubber can reveal damage after recovery; a flash limit alone is incomplete.
Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Mark trimming regions | Define allowed working faces and protected functional bands. |
| 2 · Retain limit examples | Show residual flash, steps, overcuts and tears rather than one ideal sample. |
| 3 · Relate defects to function | Compare nick location with sealing, assembly and fatigue to create usable criteria. |
A comparison to avoid misinterpretation
An equal-depth nick in a decorative edge and a sealing lip has different implications. Record location, not merely 'bad trimming'.
Frequently asked question
Is more complete trimming always better?
