Husqvarna Construction K970 III 18 Inch Bar 6.5HP Gas-Powered 2-Bolt Rear Handle Chainsaw

Description

Eighteen inches of single-pass plunge cutting depth penetrates thick foundation walls inside the Husqvarna K970 III Concrete Chainsaw. This rear-handle gas concrete chainsaw carves square window and door openings without overcutting corners. A 6.5 HP engine drives diamond chain. You must maintain thirty-PSI minimum water pressure while cutting to prevent chain wear.

Husqvarna builds the crankcase from lightweight cast magnesium alloy mated to an aluminum clutch cover. The 6.5 HP 94cc two-stroke single-cylinder gas engine spins the drive sprocket at 9000 RPM, propelling diamond chain at 5600 feet per minute. Machine weight totals 21.2 lbs without bar. Exterior tool measurements span 32 inches long by 11 inches wide by 15 inches high with a two-bolt bar mount.

Key Features of Husqvarna K970

Demolition specialists buy Husqvarna K970 III concrete chainsaws to cut square structural openings while checking commercial gas saw pricing. Cutting crews plunge eighteen inches deep through foundation walls without overcutting load-bearing header corners or damaging adjacent masonry.

• Diamond chain plunges eighteen inches deep into reinforced concrete, stone, and brick walls.
• High-output 94cc two-stroke engine provides 6.5 horsepower to maintain cutting speed in hard aggregate.
• Active Air Filtration centrifugal cleaner removes dust before air reaches the engine carburetor.
• Two-bolt guide bar clamp prevents bar deflection during heavy horizontal wall plunge cuts.
• Wet cutting kit delivers targeted water streams to flush cuttings and cool chain links.
• Anti-vibration handle design cuts hand-arm strain during extended structural wall demolition.
• Rear-handle configuration provides maximum pushing leverage during deep horizontal foundation cuts.

Chain Velocity Sprocket Drive Tolerances

Bench dynamometer testing confirms stable chain torque under heavy plunge drag. The 94cc two-stroke engine maintains 9100 RPM under load, driving the diamond chain through sixteen inches of cured four-thousand-PSI limestone concrete without engine bog. Drive sprocket runout measures under 0.0020 inches TIR on the crankshaft nose. Crankcase temperatures stabilize at 160 degrees Fahrenheit during sustained foundation wall cutting runs. Guide bar water channels maintain thirty-PSI water flow to cool chain pins and prevent thermal stretch.

Wall Plunge Ergonomics Maintenance Scope

Holding this twenty-one-pound saw against vertical concrete walls demands solid forearm grip and stable scaffold staging on high cuts. The engine decompression button eases recoil pull effort with work gloves. Do not buy this gas chainsaw for dry masonry cutting without water feed, or for continuous highway joint sawing.

• Flush the internal water channels with clean water after finishing concrete cuts.
• Check diamond chain tension and tighten guide bar nuts before each cut.
• Clean the foam carburetor pre-filter sponge every shift to prevent grit ingestion.
