STIHL MS 391 Chainsaw
Features
IntelliCarb™ Compensating Carburetor
The IntelliCarb™ Compensating Carburetor automatically adjusts the air/fuel ratio as the air filter becomes restricted or partially clogged, helping maintain consistent engine performance and RPM.
Ematic™ Lubrication System
When used with STIHL OILOMATIC® saw chain, the Ematic™ guide bar directs lubrication to the bar and chain's critical wear points. This system can reduce bar oil consumption by up to 50% compared to conventional lubrication methods.
STIHL Quickstop® Chain Brake
The STIHL Quickstop® chain brake is designed to stop chain rotation when activated manually or by inertia during certain kickback situations, helping reduce the risk of injury.
Bumper Spikes
Durable bumper spikes provide improved control and stability during cutting, helping make demanding cutting tasks easier.
Adjustable Automatic Oiler
The adjustable automatic oiler allows operators to regulate lubrication to the guide bar and saw chain based on cutting conditions.
Decompression Valve
The decompression valve temporarily reduces cylinder compression during starting, reducing the effort required to pull the starter rope. It closes automatically when the engine fires.
Pre-Separation Air Filtration System
This advanced filtration system uses centrifugal force to separate larger dirt particles before they reach the air filter. This helps extend the time between filter cleanings and reduces maintenance requirements.
Side-Access Chain Tensioner
The side-access chain tensioner allows convenient chain adjustments using a bar wrench without accessing the front of the saw.
Master Control Lever™
The Master Control Lever™ combines choke, starting throttle lock, and stop functions into one convenient control for easier operation.
STIHL Anti-Vibration System
STIHL's anti-vibration system helps minimize vibration transferred to the operator, reducing fatigue and improving comfort during extended cutting sessions.
Toolless Fuel and Oil Caps with Retainers
Convenient toolless caps allow quick access to fuel and bar oil reservoirs without additional tools.
