Description
Dense smoke conditions and freezing winter extrication calls demand the raw muscle of the Tempest 397K Fire Rescue Cutoff Saw. This ninety-four-cubic-centimeter gas saw spins fourteen-inch rescue wheels through reinforced steel doors and security grates. A two-stroke engine powers the spindle. You must adjust the carburetor choke by hand during freezing emergency calls.
Tempest constructs the saw housing from lightweight cast magnesium alloy mated to an impact-resistant composite clutch guard. The 6.4 HP 94cc two-stroke single-cylinder engine drives the one-inch arbor at 5400 RPM through a heavy-duty cogged belt. Tool weight totals 22.4 lbs without blade. Exterior dimensions span 28 inches long by 11 inches wide by 16 inches high with safety-orange protective coatings.
Key Features of Tempest 397K
Fire rescue departments buy Tempest 397K cutoff saws to breach reinforced commercial buildings while checking municipal equipment pricing online. First responders cut roll-up warehouse doors, steel bars, and concrete block walls during critical structure fires and vehicle extrications.
- High-displacement 94cc engine provides 6.4 horsepower to slice mixed rescue materials fast.
- Fourteen-inch guard clears five inches of plunge cutting depth in concrete and metal.
- Heavy-duty centrifugal clutch resists slippage when cutting binding metal security grates.
- Oversized D-ring starter handle allows rapid recoil pulls while wearing thick firefighting gloves.
- Multi-stage foam air filtration blocks fine drywall dust and soot from entering the carburetor.
- Reversible cutting arm mounts blades outboard for flush cuts against floors and curbs.
- Reflective safety markings increase tool visibility inside dark smoke-filled structural collapse zones.
Spindle Runout Engine Torque Tolerances
Bench calibration verifies high rotational torque transfer through the centrifugal clutch and cogged belt drive. The 94cc engine maintains 9300 RPM under load, driving a fourteen-inch diamond rescue blade through three-inch structural steel tube in twelve seconds. Spindle runout measures under 0.0014 inches TIR at the blade mounting shoulder. Crankcase temperatures stabilize at 160 degrees Fahrenheit under continuous load cutting. The magnesium guard resists deformation under twenty-five foot-pounds of lateral impact shock without binding the spinning blade.
Emergency Rescue Handling Maintenance Scope
Swinging this twenty-two-pound rescue saw through structural roll-up doors feels balanced, with large rubberized handles providing grip through bulky turnout gloves. The ignition switch operates positive under emergency stress. Do not buy this specialized rescue saw for continuous all-day road joint sawing or wet aggregate batch processing.
- Inspect and blow soot out of the air cleaner filter after every emergency run.
- Check drive belt tension through the inspection port every twenty operating hours.
- Clean carbon deposits off the spark plug electrode every fifty hours of use.
