EQUIPMENT FOCUS Chain Saws Echo CS-600P The new and improved Echo CS-600P chain saw features the "Performance Cutting System" consisting of a professional- quality bar and high-performance chain; a 59.8cc professional-grade, 2-stroke engine; a heavy-duty, easy-access air filter; a decompression valve; a dual post chain brake handle; a side-access chain tensioner; a clutch-driven oiler; and a computerized ignition advance for automatic engine timing adjustments. Improvements for 2012 include a redesigned piston, cylinder, and ignition module, which provides a 10-percent increase in power and torque through the cutting RPM. These changes also reduced emission levels by 40 percent, and improved fuel economy by 10 percent. It is also equipped with an aluminum handle with rubber over-mold. The CS-600P is designed for the professional tree care operator and is available in 16-, 20-, 24-, and 27-inch bar and chain lengths. Efco MT 4100 SP SS The efco MT 4100 SP SS is ideal for lopping, de-limbing, pruning, and cutting small to medium trees. The self-sharpening chain saw allows the user to continue working with an easy-to-use sharpening system on the saw. Simply attach the sharpening unit to the end of the saw, apply pressure, and the chain is ready to cut again. With an engine that meets EPA 3 standards, it ensures low fuel consumption, low emissions, and less noise. The powerful engine — 39cc, 2.5 hp. — is easy to start and has an extremely high power- to-weight ratio. The MT 4100 SP SS is easy to maintain and operate. Husqvarna T540 XP The Husqvarna T540XP top-handle saw is a new feature-packed saw targeted toward tree care professionals. The saw is powered by a 38cc X-Torq engine, which provides up to 20 percent better fuel consumption and 75 percent lower exhaust emissions. Also featured on this saw is the Auto Tune carburetor system, which guarantees that the saw will always have optimal engine performance while providing very good acceleration and allowing for maximum operating speed in varying environmental and atmospheric conditions. The T540XP has an outstanding power-to-weight ratio of 0.50. The saw also features air injection technology to maximize the amount of clean air through the engine. The clutch cover on this saw features a captured bar nut to prevent downtime in the field during chain adjustments. Jonsered CS 2166 The Jonsered CS 2166 has a new, clean-running, fuel-efficient engine, optimized to output more torque over a wider rpm range. It is engineered to provide stronger cutting power at lower rpm when the saw is under load. The CS 2166 also has a new large-diameter top handle for greater operating comfort and control. Other features include a top-mounted decompression valve, side-access chain tension adjustment, and an easy-access snap lock air filter cover. Stihl MS 201 T top-handle chain saw The Stihl MS 201 T takes over as Stihl's top arborist saw. The top-handle Stihl MS 201 T chain saw uses advanced engine technology to reduce engine emissions to a remarkable 70 percent less than the previous model. In addition, the MS 201 T delivers 20 percent better fuel economy, providing longer run times between refueling, and an improved filtration system allows for 30 percent longer operation between filter maintenance. The MS 201 T chain saw features improved ergonomics to reduce operator fatigue, including reduced vibration. For "in-tree" cutting, the top-handle design provides good balance and is ideal for use in the confined conditions of "in-the-tree" work. Tanaka TCS40EA18 Tanaka's TCS40EA18 chain saw features excellent power and versatility. Powered by Tanaka's PureFire 40cc low-emission 2-stroke engine, this commercial-grade saw contains a chrome-plated cylinder, forged-steel connecting rod, purge primer bulb and throttle latch/choke for easy and reliable starts. The saw boasts a heavy-duty, gear-driven oiler and 2 bar-mounting studs to keep the 18-inch Oregon chain at peak cutting efficiency. Also, its lighter weight (9.9 pounds — power unit only), combined with a vibration dampening system, makes this saw comfortable to operate causing less fatigue to the user. The TCS40EA18 has a complete safety package, which includes an inertia-activated chain brake/hand guard, side-access chain tensioner, and standard bucking spike. www.greenmediaonline.com/productportal 30 Arbor Age / January/February 2012 www.arborage.com EQUIPMENT FOCUS For more information about any of these chain saws, and more, visit
