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

Strong and durable to protect the saw during extreme
cutting. Mounted with aviation-style star washers to
prevent loosening due to vibration.

Angle Full Wrap Handle

Angled ergonomic handle allows safe operation in
any position and protects saw from damage.

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.
