The Wacker Neuson Oil Alert Switch Assembly is a genuine OEM component designed for the BFS 2020AS floor saw and GS12Ai portable generator. As a direct factory replacement, this assembly matches the original specification and installs without any adaptation. Wacker Neuson genuine OEM parts are sourced directly through the manufacturer to ensure correct fit and function across the confirmed compatible machines. If you're servicing a BFS 2020AS or GS12Ai and the oil alert system has become unresponsive or faulty, part number is the correct replacement to restore that protection.
Key Features
- Genuine OEM Sensing Accuracy — Factory-built to trigger at the correct oil level threshold, ensuring the alert system responds when it should — not before, not after.
- Drop-In Assembly Replacement — Supplied as a complete switch assembly, so the entire unit swaps out as one piece with no partial rebuilding or sourcing of individual components.
- Confirmed Fitment — Verified for the BFS 2020AS floor saw and the GS12Ai 50Hz portable generator; always confirm your machine's model and serial number before ordering.
- Engine Protection Where It Counts — A correctly functioning oil alert switch cuts power before low oil causes catastrophic engine damage; a failed switch leaves the engine running blind to dangerously low oil levels.
- Critical Safety Function — This switch is a front-line safeguard against engine seizure; using a genuine OEM assembly ensures the shutoff threshold matches the engine manufacturer's requirement exactly.
The oil alert switch assembly monitors the engine's oil level during operation and sends a signal to shut down or alert the operator when oil drops below a safe threshold. This protection is critical on equipment like floor saws and portable generators, where engines run under sustained load and low oil can quickly lead to overheating and irreversible internal damage. When this switch fails — whether it stops triggering or triggers incorrectly — the engine loses its primary safeguard against low-oil conditions, making prompt replacement essential.
