Product Overview

The Husqvarna K770 Rescue Saw is a compact, high-output gas-powered cutter designed for high-stress rescue operations involving buildings, vehicles, aircraft, and subway systems. Its magnesium blade guard is finished with reflective tape for visibility in smoke, water spray, and low-light conditions—enhancing operator safety and blade placement control.

Key Features and Technologies

• 5 HP, 2-Stroke X-Torq Engine: Efficient, emission-reducing design delivers rapid, reliable starts and instant torque critical for life-saving situations.

• Magnesium Reflective Blade Guard: Lightweight, corrosion-resistant, and designed for visibility through smoke and water spray.

• Active Air Filtration: Three-stage filtration system increases engine longevity and reliability, reducing downtime during extended incidents or frequent training cycles.

• SmartCarb™ and Durastarter™: Integrated auto-compensation maintains power as the filter loads with debris, while the maintenance-free starter system ensures first-pull dependability.

• Ergonomic “D” Starter Handle: Designed for gloved use, optimized for rapid, safe deployment by first responders in full PPE.

• Reversible Cutting Arm: Lets the rescuer cut flush against surfaces, walls, or ground—perfect for entry, ventilation, or vehicle extrication.

• Heavy-Duty Poly-V Belt & Crankcase: Upgraded cast magnesium three-bolt crankcase resists torsional flex and abuse, extending service life.

• Clutch Cooling Fan: Lowers transmission temperature to extend drive belt and transmission life, even in prolonged use.

• Adjustable Carry Strap: Allows for hands-free operation and full freedom of movement, reducing strain in complex rescue scenarios.

• Utility Tool Holder: Wrench (scrench) is integrated, so crews always have essential tools at hand.

Technical Specifications

Primary Rescue Benefits

• Fast, First-Start Operation: Digital ignition, decompression valve, SmartCarb™, and a big D-handle starter ensure the saw roars to life instantly, even after storage or in cold conditions.

• All-Condition Visibility: Magnesium blade guard with reflective tape means visibility doesn’t suffer in smoke, water, fog, or low-light events—unmatched safety for rescue teams.

• Cutting Versatility: Built to handle masonry, concrete, rebar, steel door frames, car roofs, airplane skin, and more, depending on the blade. Designed for rapid access, venting, and egress in critical scenarios.

• Lightweight, Maneuverable Design: Weighs less than 22 pounds but packs 5 HP—making it the most compact high-performance rescue saw in its category; essential for roof work or carrying up ladders.

• Rugged Reliability: Poly-V heavy-duty belt, cast magnesium crankcase, and advanced cooling ensure durability and long service intervals for demanding departments or contractors.

Applications & Industry Use

• Fire and Rescue: Cutting roofs for ventilation, concrete or brick walls for rapid access, forced entry, and disentangling vehicle wreckage.

• Public Safety/Military: Urban search and rescue, train/aircraft forcible entry, heavy-duty disaster response, and tactical breaching.

• Construction/Demolition: Used for tough cement, steel, and composite cutting where time, reliability, and portability are paramount.
