The FSB-150 makes straight, upright cuts in concrete and asphalt where a gas walk-behind saw is too heavy, too fumey, or simply not allowed: sidewalk repair, interior trench cutting, and asphalt patching. Air drive means no engine exhaust at the cut, which is what puts it inside buildings and down in structures where gas saws stay on the truck.

The geared air drive has no belt to slip under load, and the saw's weight sits balanced over the blade so it tracks a line without rocking. At 144 pounds it loads and moves with far less fight than a gas flat saw of the same cutting depth. The package arrives cut-ready with a water feed kit for wet cutting, whip hose, oiler, and wrenches. This is the flat saw for municipal and utility crews already running compressor trucks, cutting sidewalks and trench lines day in and day out.

Common Applications

  • Sidewalk repair cutting
  • Interior trench cutting
  • Asphalt patch cutting

Selection Notes

  • Requires a 90 CFM at 90 PSI air source; size the compressor before the saw
  • The same frame runs as the hydraulic FSB-150H for crews on hydraulic power packs instead of compressors
  • Runs blades to 20 in for the full 7.5 in depth of cut
