Evidence level
Manufacturer documentation; no physical testing

A source check date records this research pass. It does not confirm that a manual is the newest possible revision, a tool is still in production, or a particular unit matches these documents.

Keep the limits in view.

  • Documentation-based; no hands-on testing, durability ranking, or independent performance claim.
  • US version only; match full nameplate and manual revision.
  • Tank volume is not usable liquid capacity; peak HP is not continuous working power.
  • No hazardous-dust, sewage-remediation, or flammable-liquid approval is established.

Read the instructions for the tool and any applicable battery or charger together. Routine owner care stays outside the housing; internal service belongs with the manufacturer or an authorized service provider.
