Features
Powerful and Efficient X-TORQ® Engine: X-Torq® engines deliver a great power and torque thanks to highly efficient combustion.
LowVib® Technology: Dampeners between the engine and chassis significantly reduce vibrations so you can work more comfortably
Smart Start® Technology: Specially-designed engine and starter for easy and fast starting with minimum effort
Quick Start with Air Purge: Air purge removes air from carburetor and fuel system for easy starting
Air Injection™ Technology: Centrifugal air cleaning system expels larger dust and debris particles before they reach the air filter to help improve engine life
Combined Choke/Stop Control: Provides easier starting and reduces the risk of engine flooding
Three-Piece Crankshaft: Forged three-piece crankshaft delivers maximum durability for even the toughest of jobs
Inertia-Activated Chain Brake: Reduces the likelihood of injury due to kickback.
Side-Mounted Chain Tensioner: Easier access to chain tensioning device.
Flip-Up Fuel Cap: Easy to open and secures firmly, even when wearing thick gloves
Fuel Indicator: Transparent fuel indicator makes it easy to check fuel level
Quick-Release Air Filter: Easily remove and replace the filter after cleaning
