Features

• 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.
• DECOMPRESSION VALVE: The decompression valve reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope.
• 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.
• X2 AIR FILTRATION SYSTEM: The X2 Air Filtration System revolutionizes the cut-off machine industry by allowing air filters to last up to a year, based on cutting conditions. Outside air enters the system in a swirling motion, removing 80% of dust particles. This pre-cleaned air is then routed through the primary and secondary air filters before being sent into the engine. The X2 Air Filtration System is virtually maintenance free and maintains an incredible 99.96% cleaning efficiency.
• SEMI-AUTOMATIC BELT TENSIONING: With consistent, semi-automatic re-tensioning, this feature increases the service life of the belts and shaft bearings.
• 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.
• ERGONOMIC GRIP: The ergonomic top-handle bar design provides an optimal comfortable grip in any working position.
• REPLACEABLE "IN TANK" FUEL FILTER: Lowers cost and is easy to maintain.
• HEAVY-DUTY AIR FILTRATION SYSTEM: The TS 410, TS 420, TS500i, TS 700 and TS 800 feature the X2. The X2 air filter system uses centrifugal force to separate large dirt particles before they come in contact with the air filter.
• STRATEGICALLY PLACED AIR INTAKE: Rear placements helps filter stay cleaner longer.
• UPRIGHT AND ENLARGED FUEL PORT: For easy fueling.
• BAYONET-STYLE FUEL CAP: With retainer for easy use, even with gloves on.
• THROTTLE TRIGGER LOCKOUT: Must be depressed before the trigger can be activated.
• PROTECTED THROTTLE TRIGGER: Helps prevent damage.
• ON/OFF SWITCH: Conveniently located on top of handle and recessed to prevent accidental shutdown.
• SPARK PLUG: Protected yet easy to change.
• HIGH-TECH POLYMER HOUSINGS: Lightweight and corrosion-resistant.
• HIGH-PERFORMANCE COOLING SYSTEM: For superior air flow and heat dissipation.
• PROTECTED DECOMPRESSION VALVE: Makes starting easier.
• 2-RING PISTONS: Improve engine efficiency and holds compression longer than 1-ring pistons. Also, 2-ring Pistons transfer heat from the piston to cylinder better, helping engine stay cooler and last longer.
• LONG-LIFE CYLINDERS: Provide optimal cooling, lubrication and more power output per cubic centimeter of engine displacement for maximum wear life.
• SPARK ARRESTOR MUFFLER: Has large baffles which reduce noise level, and contains a screen designed to reduce the emission of sparks.
• INTERGRATED WATER SUPPLY HOSE: Helps prevent hose damage.
• SEMI-AUTOMATIC BELT TENSIONER: Allows for easy adjustment of drive belt.
• REVERSIBLE CUTTING ARM: Lets you cut in the inboard or outboard position.
• WATER KIT: Reduces dust when cutting concrete when attached to a water supply.
• BALANCE AND DESIGN: Helps reduce fatigue and makes handling easy.
• ELECTRONIC IGNITION: Provides easy starting and smooth running.

Other Features

• INTELLICARB™ COMPENSATING CARBURETOR: Measures air on clean side of air filter and adjusts metering diaphragm in carburetor. Keeps RPM level even when filter begins to clog.
• ELECTRONIC WATER CONTROL: Allows operator to easily adjust the flow of water while cutting and stops the water flow when the machine is at idle.
• ANTI-VIBRATION SYSTEM: Helps to reduce operator fatigue.
