Husqvarna Construction K 970 Ring Saw Gas 6.5 Hp 10.6in Cutting Depth

Description

Muddy trench water and tight clearance spaces make cutting deep concrete pipes from one side an absolute necessity. The Husqvarna K 970 Ring Saw plunges ten-point-six inches deep using specialized peripheral drive wheels. A 6.5 HP engine powers through reinforced concrete. Operating ring blades requires steady water flow to lubricate drive rollers, stopping work if water pressure drops.

High-tensile magnesium forms the engine crankcase, starter housing, and blade arm, resisting jobsite impacts while shedding heat. The 93.6 cc two-stroke gas engine generates 6.5 HP at 9,000 RPM, turning ring blades via a peripheral drive roller system. Bare tool weight sits at 29.8 lbs, presenting an exterior envelope of 30.7 by 8.9 by 17.0 inches that stores inside utility truck beds.

Key Features of Husqvarna K970

Underground utility contractors, foundation specialists, and pipe layers deploy this gas ring saw for deep pipe cutouts, door openings, and thick slab trenches. Review commercial distributor pricing to buy Husqvarna K 970 ring saws for extreme single-pass cutting depth.

• Ninety-four cubic centimeter engine delivers high torque to drive fourteen-inch ring blades.
• Ten-point-six inch cutting depth matches double the capacity of conventional circular saws.
• Peripheral drive mechanism eliminates center arbors to permit deep plunge passes.
• Active Air Filtration uses centrifugal cyclone stages to extend paper filter life.
• SmartCarb automatic filter compensation preserves optimum air-fuel ratios as dust collects.
• Integrated water delivery manifold floods drive rollers to prevent friction overheating.
• Anti-vibration spring mounts isolate intense engine shudder from operator hands.
• DuraStarter sealed starter mechanism prevents abrasive slurry from jamming recoil cords.

Drive Roller Torque Load Metrics

Drive roller runout tests within 0.0012 inches TIR across the hardened drive groove face. Under full ten-inch plunge cuts in cured limestone concrete, engine speed drops from 9,000 RPM free spin down to 8,200 RPM without cylinder misfire. Water delivery pressure must maintain 20 PSI to hold drive roller temperatures below 140 degrees Fahrenheit. The centrifugal clutch locks up hard past 4,200 RPM, transferring engine power without rotational slip. Drive roller wear grooves require inspection after thirty hours of deep cutting.

Trench Plunge Handling Service Realities

Weighing nearly thirty lbs with water kit installed, this saw requires firm two-handed leverage during horizontal pipe penetrations. The rubberized stop toggle and choke operate without issue through wet leather work gloves. Do not buy this machine for shallow asphalt expansion joint grooving or light block trimming. Heavy civil utility contractors and foundation demolition teams gain incredible production savings from this deep-cutting platform.

• Wash the foam air pre-filter every week with warm soapy water.
• Adjust guide roller tension screws before starting each deep cutting shift.
• Flush abrasive concrete slurry from drive roller housings after finishing each workday.
