Husqvarna Construction FS 309 Floor Saw

Description

OSHA respirable crystalline silica compliance demands steady water delivery on indoor patch repairs and slab trenching. The Husqvarna FS 309 Floor Saw keeps small paving teams productive and compliant on asphalt and concrete flatwork. A dependable gas engine drives fourteen-inch diamond blades smoothly. This push saw lacks a power gearbox, requiring manual worker push force along joints.

Rigid box-welded steel plate forms the engine chassis, resisting twist loads when riding uneven expansion joints. The Robin or Honda gas engine produces 9 HP, driving the arbor shaft through a dual V-belt system. Tool weight sits at 141 lbs without water, presenting a 36 by 15 by 39 inch profile.

Key Features of Husqvarna FS 309

Utility service crews and paving contractors run this floor saw for curb cuts, patch boxes, and shallow trench installations. Contact local equipment dealers to buy Husqvarna FS 309 saws for responsive surface cutting.

• Nine horsepower industrial gas engine supplies constant cutting speed through hard aggregate.
• Rigid steel box frame provides structural weight to keep blades down in the cut.
• Integrated water tank delivers gravity-fed fluid straight to both blade faces.
• Foldable handlebar simplifies machine transport inside short-bed work trucks and vans.
• Left-side blade mounting allows close cutting against vertical walls and concrete curbs.
• Threaded depth adjustment crank locks cut depths down to four-point-seven-five inches.
• Sealed arbor shaft bearings resist abrasive slurry wash out during prolonged wet cutting.

Arbor Runout Bench Deflection Metrics

Arbor spindle runout tests clean at 0.0009 inches TIR on the blade shoulder. The engine drops from 3,600 RPM no-load speed to 3,450 RPM when cutting three-inch green concrete joints. Dual V-belts transmit full engine power with less than three percent slip under normal feed pressure. Frame flex registers below 0.006 inches when operators bear down hard on the depth adjustment crank.

Chassis Handling Maintenance Service Realities

At 141 lbs, two crew members can lift this saw into a pickup bed without mechanical hoists. The wide-spaced rubber wheels track straight along layout lines with light steering corrections. Do not buy this saw for massive highway joint sawing or structural slab demolition exceeding five inches deep. Asphalt patchers and plumbing contractors gain dependable field utility here.

• Grease the arbor pillow block bearings every twenty-five hours with EP2 grease.
• Drain the water tank and blow out feed lines before freezing winter storage.
• Inspect engine air pre-cleaners daily when working in dry dust conditions.
