MS 660 Magnum

Talk about legendary. If there are large trees that must be felled, more than likely, this is the saw that gets the nod. The MS 660’s amazing power-to-weight ratio gives you a whole lot more power (a 15% increase in engine power over the MS 460!) with only a marginal increase in weight. Small wonder, then, that it’s been the chainsaw of choice for so many professionals, and the saw chosen for use in the STIHL® TIMBERSPORTS® Series.

STIHL Chainsaw

Model Feature

  • STIHL Quickstop®

    STIHL chain saws are equipped with a chain stopping system designed to reduce the risk of injury in certain kickback situations. It is called a STIHL Quickstop® chain brake. The STIHL Quickstop® chain brake is designed to stop the rotation of the chain if activated by the operator’s hand or by inertia if the saw kicks back with sufficient force. In some working positions, the STIHL Quickstop® chain brake can be activated by inertia, stopping the chain within fractions of a second.

  • 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.

  • STIHL ElastoStart™

    The ElastoStart™ starter handle is an exclusive feature of STIHL. It is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord. The ElastoStart™ starter grip noticeably reduces the sudden peak forces (compression) normally felt during cranking. The forces which occur at the grip after the first compression stroke are smoothed out.

  • Decompression Valve

    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%.

  • 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.

  • Winter/Summer Shutter

    The Winter/Summer Shutter allows the carburetor to operate at optimum temperature year-round and helps to prevent carburetor icing when working below 50°F (10°C).

  • 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%.

  • 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.

  • 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.

  • Adjustable Automatic Oiler

    The Adjustable Automatic Oiler allows the user to adjust the lubricant of the guide bar and saw chain for different bar lengths and cutting conditions.
