The Husqvarna 542166459 Filter is a genuine OEM replacement designed for the FS8400D floor saw. Sourced directly from Husqvarna, this filter meets the exact specifications required for proper machine operation on the FS8400D. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Filtration Media — Built to Husqvarna's exact material and flow specifications for the FS8400D, ensuring the filter performs as intended rather than approximating the spec.
- Direct Drop-In Replacement — Engineered to seat and connect exactly as the original, so installation on the FS8400D is straightforward with no reworking of surrounding components.
- FS8400D Floor Saw Compatibility — Confirmed fitment for the FS8400D walk-behind floor saw, so you can order with confidence using part number 542166459.
- Protects Critical Engine or Hydraulic Components — A correctly functioning filter keeps contaminants out of the system it serves, maintaining consistent power delivery and protecting downstream components from premature wear.
- Contamination Control — A clogged or degraded filter restricts flow and allows particulates to reach sensitive components; replacing it on schedule with the correct OEM part keeps the FS8400D operating within its design parameters.
A filter serves as the primary barrier between contaminants — dirt, debris, and fine particulate — and the engine or hydraulic system it protects on the FS8400D floor saw. By trapping particles before they circulate through the system, the filter preserves oil or air cleanliness and prevents accelerated wear on pumps, bearings, and other precision components. When a filter becomes saturated or damaged, flow restriction increases and protection drops, which can lead to overheating, power loss, or costly internal damage if left unaddressed.
