The VentMaster® 576-HD and 365-HD fire rescue chainsaws deliver the absolute best in cutting performance, built specifically for the fire service. Using professional level Husqvarna® power heads and Tempest exclusive after-market parts, no other saw compares in durability, reliability, cutting performance and cutting versatility.


X-TORQ Engine
Husqvarna® power head increases torque over a wider RPM range for maximum cutting power. Larger displacement, best fuel economy in its class, higher peak power, 20% more torque and even better ergonomics for maximum productivity.

Sealed & Protected Carburetor/Air Filter
35% better engine cooling due to cover design in relation to cooling fan design. Air Filter cannot be crushed or lost. Tool-less compartment entry for easy access to spark plug, air filter, inspection and cleaning of cylinder cooling fins. Greatly reduces filter clogs.

Tool-Less “KIS-40” Depth Gauge
Accurately control cutting depth, protect operator and safely speed cut. Fast, simple installation and removal, and eliminates the need to “roll the rafters”. 

VentMaster COBALT Guide Bar
Extremely hard COBALT alloy inserts at the wear points provide excellent wear, galling, and impact resistance. Retains these properties even at very high operating temperatures.

Centrifugal Force Air Cleaning System
Preliminary air intake cleaning rejects 97% of cutting residue and other airborne debris including drywall dust, concrete dust, smoke, water spray and more. Cleaner intake air means longer intervals between filter cleanings, longer runs at full power, less chain damage, smoother operation and reduced internal engine wear.

Raptor Carbide Chain
Engineered specifically to withstand the rigors of fire and rescue operations. Features an “open dual raker” design to protect the carbide cutters and control the depth of cut.
Tough and versatile enough to cut through:

– Plexiglass, Lexan & Hurricane Glass

– Tar and Asphalt Roofing 

– Nails 

– Light-Gauge Sheet Metal 

– Wire-Reinforced Belting

– Trees and Green Wood

  and More

Plated Steel Splash Guard

Angle Full Wrap Handle

One Step Start/Stop
Combined Choke/Throttle Lock/Stop Switch eliminates flooding and allows fast, convenient starting and One Push positive stop, even with gloves.

“Smart Start” Decompression Valve
Valve reduces cylinder pressure for less starting resistance and easier starts.
