This demonstration guide answers one field question about a guard that was removed after a prior repair. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with guard presence and fastener torque. That reading separates a guard that was removed after a prior repair from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the guard as the primary path. If it is in spec, do not replace the guard just to complete a parts list.
Repair the failed system
The usual correction is the guard, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about a guard that was removed after a prior repair.
Stop before you make it worse
Do not running without a guard because debris "packs less". That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the guard is corrected, convert the visit to a broader diagnosis rather than stacking parts.
