Description
Plunge twenty-two inches deep through structural concrete walls using the Husqvarna PRIME K 7000 Chain Saw. This high-frequency electric concrete chainsaw cuts square door and window corners without overcutting structural headers. A water-cooled motor produces massive cutting torque. You must connect this saw to an external Husqvarna PP 70 power pack on site.
Husqvarna manufactures the saw housing from lightweight cast magnesium alloy paired with a rigid aluminum nose bar support. The high-frequency permanent magnet electric motor produces 7.4 HP on 400V three-phase or 4.0 HP on 230V single-phase power from the PP 70 pack. Unboxed saw weight registers at 21 lbs without bar. Frame dimensions span 21 inches long by 8 inches wide by 16 inches high.
Key Features of Husqvarna K 7000
Demolition specialists buy Husqvarna PRIME K 7000 chain cutters to execute square corner openings while evaluating commercial concrete equipment pricing. Concrete cutting crews plunge deep through thick foundation walls without overcutting adjacent structural load-bearing headers.
- Diamond chain plunges up to twenty-two inches deep for thick foundation wall penetration.
- High-frequency electric motor eliminates gas exhaust fumes for clean indoor basement cuts.
- Water cooling circuit cools the stator while flushing concrete grit off diamond chain links.
- Anti-vibration handle design cuts hand-arm strain during extended horizontal wall cuts.
- Digital motor protection prevents stator burnout if operators push excessive cutting force.
- Reversible guide bar extends wear life when running abrasive aggregate concrete cuts.
- Sealed ball bearings block pressurized wash water and abrasive grit from entering motor windings.
High Frequency Torque Thermal Tolerances
Bench testing on the high-frequency motor verifies steady torque delivery across heavy chain drag loads. Connected to a PP 70 power pack on 400V service, the motor draws 16 amps under a twenty-inch plunge in steel-reinforced four-thousand-PSI concrete, holding chain speed at 5700 feet per minute. Stator winding temperatures stabilize at 140 degrees Fahrenheit thanks to the continuous internal water-cooling jacket. Guide bar flex stays under 0.015 inches under thirty-five pounds of lateral plunge thrust without chain derailment.
Plunge Cutting Ergonomics Maintenance Limits
Balancing this twenty-one-pound chainsaw against vertical concrete walls is manageable, though extended overhead cuts require two-man staging or scaffold platforms. The water control valve operates crisp through wet work gloves. Do not buy this specialized high-frequency chain cutter if your company lacks a compatible Husqvarna PRIME power pack.
- Flush the internal water cooling channels with clean water after each shift.
- Check diamond chain tension and tighten the guide bar bolts before each cut.
- Grease the nose sprocket bearing with water-resistant marine grease every four hours.
