Husqvarna Construction FS 513 Floor Saw Without Tank

Description

Feel the mechanical push resistance drop as you track a straight joint through curing green slab. The Husqvarna FS 513 Floor Saw delivers pure gas power for mid-sized pavement repair and expansion joint work. A commercial four-stroke engine spins sixteen-inch diamond blades reliably. The push-cart design demands manual operator drive power, which tests endurance on uphill grades.

Welded heavy-gauge steel forms the engine mount and chassis plate, damping engine vibration before it reaches the cut line. The Honda GX390 gas engine produces 11.7 net HP at 3,600 RPM, burning regular unleaded fuel. The bare machine weighs 218 lbs, occupying a compact 37 by 21 by 39 inch transport footprint.

• Retractable guide wheel tracks straight cuts along long industrial slab chalk lines.
• Adjustable handle assembly isolates hand-arm vibration to protect crew joints.
• Arbor shaft incorporates heavy greaseable flange bearings for wet slurry resistance.
• Threaded depth crank locks cutting depth at exact fractional inch increments.

Arbor Shaft Runout Deflection Metrics

Arbor runout measures 0.0011 inches TIR at the blade contact collar. The Honda GX390 drops from 3,600 RPM to 3,420 RPM under full four-inch plunge cuts into limestone aggregate concrete. Belt drive slip remains zero when tensioned to manufacturer specifications. Frame deflection measures under 0.005 inches under heavy operator downfeed pressure. Exhaust gas temperatures stabilize near 410 degrees Fahrenheit during long highway shoulder runs.

Operator Ergonomics Shop Service Realities

Vibration dampers inside the handlebar keep joint fatigue low, allowing operators to run multiple tanks across single shifts. The throttle lever and engine kill toggle mount within thumb reach on the console. Do not buy this machine for indoor basement cutting or deep twelve-inch foundation cuts. Road repair contractors and flatwork slab crews gain real production advantages here.

• Grease blade shaft pillow bearings every twenty operating hours using lithium grease.
• Inspect engine oil levels before every shift and replace oil every fifty hours.
• Check Poly V-belt tension every week to prevent premature belt shredding.
