Description

The STIHL MS 661 C-M MAGNUM® is a professional-grade chainsaw. It’s built for demanding, high-volume cutting work. M-Tronic™ intelligent engine management removes the usual carburetor adjustment screws. It compensates automatically for a dirty filter, elevation changes, and fuel quality. The IntelliCarb™ compensating carburetor keeps engine RPM correct as the air filter clogs. An HD2 air filter gives the engine long-lasting protection in dusty conditions. The Quickstop® chain brake stops the chain by hand or by inertia during a kickback. An anti-vibration system reduces operator fatigue during long cutting sessions. An Ematic™ guide bar system directs oil precisely to cut bar oil consumption by up to 50%. A side-access chain tensioner makes chain adjustments quick and simple.

Parallel Ag backs every MS 661 C-M with genuine STIHL parts and expert service support.

Features

Smart Engine Technology

M-Tronic™ Engine Management
Removes the low- and high-speed carburetor adjustment screws. It compensates automatically for a dirty air filter, changes in elevation, and fuel quality.

IntelliCarb™ Compensating Carburetor
Draws air from the clean side of the filter to automatically adjust the air/fuel ratio as the filter clogs, keeping engine RPM correct.

HD2 Air Filter
A washable filter with a large surface area for long life, longer run times between cleanings, and better engine protection in dusty or dry conditions.

Built for Easier Starting

ElastoStart™ Starter Handle
A starter grip with a built-in shock absorber that reduces the peak forces felt during cranking and smooths out forces after the first compression stroke.

Decompression Valve
Manually vents cylinder compression during cranking to ease starting and reduce rope-pull effort, then closes automatically once the engine fires.

Master Control Lever™
One lever controls the choke, starting throttle lock, and on-off switch for simpler starts.

Built for Safety & Control

Quickstop® Chain Brake
Stops chain rotation when activated by hand or by inertia during a kickback. In some positions, inertia activation stops the chain within fractions of a second.

Spikes
Prevent pull-in and give better control, making cutting easier.

Anti-Vibration System
Reduces vibration levels to lessen operator fatigue and improve comfort.

Smart, Easy Maintenance

Ematic™ Guide Bar System
Two ramps in the guide bar rail direct oil to the sliding surfaces, rivets, and driver holes, cutting bar oil consumption by up to 50%.

Adjustable Automatic Oiler
Lets the operator adjust lubricant flow to the guide bar and saw chain for different bar lengths and cutting conditions.

Side-Access Chain Tensioner
Lets the operator adjust the saw chain with a bar wrench from the side, rather than at the usual guide bar adjustment point.
