Description
Overview:
The Exhaust Extension fits the Husqvarna FS400 series floor saws and is a genuine Husqvarna OEM part (543 04 78-41). Built from heat‐resistant metal for durability, it channels engine exhaust away from the operator and work area to support cleaner, safer cutting. By extending the outlet, it also helps reduce perceived noise at the operator position and keeps fumes clear of the cutting line. Purpose‐designed for heavy site use, it is a reliable choice for routine maintenance or refurbishing well‐used saws. This extension is engineered for Husqvarna walk‐behind floor saws such as the FS400 and FS400LV, ensuring correct alignment with the silencer and consistent performance under sustained load.
Key Features:
- Genuine Husqvarna OEM component for assured fit and function
- Heat‐resistant metal construction suited to continuous site work
- Directs exhaust gases away from the operator to improve comfort
- Helps reduce exhaust noise at the operator position
- Robust design to withstand vibration, dust, and weather exposure
- Precisely formed outlet for stable gas flow and smooth engine operation
- Straightforward to fit with standard hand tools (no modifications normally required)
- Compatible with multiple Husqvarna floor saw models for fleet consistency
- Supports compliance with good site practice by managing fume direction
- Low‐maintenance part that integrates with the existing silencer assembly
Typical Applications:
Use on construction and roadworks sites, concrete cutting, slab and trench work, and utilities installation. Ideal where controlling exhaust direction and reducing operator exposure to fumes and noise is important, including indoor or semi‐enclosed areas with appropriate ventilation and in noise‐sensitive locations.
