Most impressive -- and almost startling -- is the ignition system. As with all gas saws, you have to juggle the choke and throttle before the engine heats up and runs smoothly. Then, only a slow, gentle cord-pull will start this saw.
The unusual feature uses a dual-spring system. The first winds to store power in the second, which trips toward the end of the pull and delivers a concentrated kick to the engine. You'll probably use less than half the speed and force you're used to when pull-starting saws, lawn mowers and other outdoor power equipment.
Unlike most saws that come with a separate wrench to undo bolts and gain access for chain tensioning, this Stihl model provides a built-in adjustment.
Flip up a finger-grab (those tools are always with you), and a turn will tighten the chain -- a real hassle-saver when you're doing a lot of cutting.
• Husqvarna Gas Chainsaw; model 455 Rancher; $370.
This basically commercial-grade tool packs as much power and capacity as you could want -- and a quick-tripping chain brake just in case. Developing 3.3 horsepower in a manageable 11-pound package, the chain spins to 12,500 rpms to cut quickly through large logs.
The big engine is aided by a push-bulb for priming (aside from the standard choke) and a compression release valve to make starting easier. A streamlined air-filtration system removes up to 97 percent of dirt and dust before it reaches the air filter.
Husqvarna points out that you can customize your purchase, for instance, buying the basic Rancher model with a longer or shorter bar depending on the work you'll be doing. You can also specify different chain configurations to optimize cutting speed through the kind of wood you'll be cutting.
There are more powerful saws. But unless you're going into the logging business, there's no need to look past this tool.
• Echo Gas Pole Saw; model PAS-230; $430.
This specialized tool has extension bars separating the compact engine at one end and a pint-sized guide bar and chain at the other. The distant business end is a genuine chainsaw, just small, which makes it ideal for pruning limbs up to about 12 feet off the ground.
The configuration seems unwieldy at first. But the engine weight at one end (about 8.5 pounds with the bar) and adjustable handhold on the extension bar provide surprisingly good balance and control.
There are longer pole saws with adjustable, telescoping bars. This model has a fixed length, but accepts a chainsaw and ten other attachments, including a brushcutter, edger and hedge trimmer.
Echo's Pro Attachment Series is available with two different engines, each compatible with the full line of extensions that snap and lock securely into the 40-inch motor section. You can opt for the larger engine and chainsaw ($430), or, for example, the smaller engine and trimmer attachment ($280), and add other units later.
