Why It’s a Smart Pick

The STIHL® MS 291‑Z is a smart pick for users who need added cutting reach without stepping up to a heavier professional saw. With its powerful engine, balanced 20in bar setup, and reduced‑maintenance design, it’s well suited for land management, firewood production, and demanding property work.

Description:

The MS 311 is a high-tech workhorse with low fuel consumption and reduced exhaust emissions. This powerful saw is ideal for large properties, farms, and ranches. It offers several comfort features, such as a side-access chain tensioner, an advanced anti-vibration system, and toolless fuel and oil caps with retainers. The MS 311 also has large fuel and oil tanks for extended use. With STIHL advanced engine technology, you get higher fuel economy and longer run times. You’ll stay productive while you’re saving money on fuel. With fuel-efficiency and a high-powered engine, the MS 311 will help reduce your downtime on the job—so you can enjoy your own downtime when the job is done.

Features:

• Powerful Low Exhaust Emission Engine - A powerful low exhaust emission engine saves users fuel and operating costs without losing the power they count on to get the job done.
• IntelliCarb™ Compensating Carburetor - The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.
• Bumper Spikes - These spikes prevent pull-in and provide better control, making cutting easier.
• Decompression Valve - The decompression valve, also referred to as 'deco' or 'deco valve', vents compression in the cylinder for easier starting. The decompression valve temporarily reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope. It is opened manually and closes automatically as soon as the engine fires.
• Toolless Fuel and Oil Caps with Retainers - Simply lift the lever and twist the caps to remove or tighten. There’s no need to use a tool to tighten or loosen.
• Pre-Separation Air Filtration System - This time-saving technology boosts the efficiency of the engine’s filter system, doubling the time between air filter cleanings. Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance.
• Side-Access Chain Tensioner - The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw.
• Anti-Vibration System - STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.
• Master Control Lever™ - The Master Control Lever™ is an easy to use single lever, operating the choke, starting throttle lock, and on-off switch. The operator must pull the throttle trigger before moving the Master Control Lever™ to the choke position.
• Throttle Trigger Interlock - This safety feature must be depressed before the trigger can be activated.
• High-Tech Polymer Housings - Housings are lightweight, withstand greater impact, and are corrosion-resistant.
• Reduced-Emission Engine Technology—Caring for Nature - The STIHL Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards.

Description:

No pulling on cords, fuel mixing, or complicated startup procedures with the MSA 200 C-B chainsaw. Just squeeze the trigger and start cutting. In addition to easy starting, battery-powered tools in the STIHL AP System produce zero exhaust emissions and are quieter than their gas-powered counterparts, making them an ideal choice for areas with emission or noise restrictions. Powered by an interchangeable STIHL lithium-ion battery, this chainsaw delivers the speed, cutting capacity, and run time to take on just about any cutting job. The STIHL MSA 200 C-B is a battery-powered chainsaw tough enough to carry the name STIHL.

Run time may vary based on battery type, charge level and capacity, model, operating style, and conditions. Batteries and chargers can be purchased separately or as a combined set with tool.

This tool is IPX4-rated for weather-resistant construction and has been designed and tested for splash-water protection.

Features:

• IPX4 Rating - This tool is IPX4-rated for weather-resistant construction and has been designed and tested for splash-water protection.
• Ematic™ Lubrication System - The Ematic™ guide bar, when used with STIHL OILOMATIC® saw chain, will provide proper lubrication and less oil consumption than conventional methods. The system works because two ramps, strategically placed in the guide bar rail, help contain the flow of oil and direct all lubrication to the sliding faces of the bar and chain links as well as the rivets and driver holes, which in turn can reduce bar oil consumption up to 50%.
• Quick Chain Adjuster (QCA) (B) - The Quick Chain Adjuster (QCA) (B) allows the user to adjust the tension of the chain without the use of tools. This allows for easy chain adjustment.
• Lightweight Portability - This product is lightweight for easy portability, great maneuverability, and extended use.
• Variable-Speed Trigger - The variable-speed trigger allows precise control for each task.
• Rubberized Soft-Touch Handle - Soft rubber texture is both easy to grip and makes the product comfortable to hold for extended periods.
