Key Highlights:
-
IntelliCarb™ Compensating Carburetor
Automatically adjusts the air-fuel mix as your air filter gets dusty, keeping engine RPMs stable and consistent—and saving you subsequent tune-ups. -
Pre-Separation Air Filtration System
Uses centrifugal force to eject heavier debris before it reaches the air filter, effectively doubling the intervals between cleanings. -
Bumper Spikes
Anchor into the wood to prevent the saw from slipping or pulling in—improving your precision and control. -
Toolless Fuel and Oil Caps with Retainers
Access fuel and oil quickly—just lift and twist caps; no tools, no hassle, and no lost caps. -
Side-Access Chain Tensioner
Fast, convenient chain adjustment with the bar wrench—even mid-cut. -
Anti-Vibration System
Lowers vibration transmitted to your hands, reducing fatigue and letting you work more comfortably over extended periods. -
Master Control Lever™ and Throttle Trigger Lockout
Simplifies the startup sequence by combining choke, throttle lock, and on/off in one lever—activated only when the throttle trigger lockout is depressed for added safety. -
High-Tech Polymer Housing
Lightweight yet durable and corrosion-resistant—built to withstand the elements without weighing you down.
