Inspection Discovery Statement

This information is based on direct inspection and observations made during routine operation and maintenance of a Butler truckmount system in active service.

During normal use, irregular system behavior prompted further inspection of components located behind the front control panel and within the wiring and pump area. The system had been operating under standard working conditions consistent with daily carpet cleaning operations.

Upon accessing the rear of the front panel and surrounding wiring areas, visible conditions were observed and documented. These included sections where wiring insulation appeared worn or deteriorated, areas where conductors were exposed, and locations where wiring routing allowed contact with surrounding surfaces.

Inspection of the pump area also revealed conditions related to wiring integrity and grounding connections. These observations were made visually and through routine inspection without disassembly beyond normal access points.

This information is being shared to document real-world observations and to encourage other operators to inspect their own equipment. No conclusions are being made regarding design, manufacturing, or compliance.

This documentation reflects observations from a single system and is provided for informational and preventative awareness purposes only.
