Stihl Delivers Cordless Power in a String Trimmer

Stihl FSA 56 string trimmerWith every new year’s lawn season, we can count on one thing: that battery-powered outdoor tools will creep even closer in performance to their gas-powered siblings. And now and then, you needn’t shell out a lot of green to own green gear. The Stihl FSA 56 string trimmer, from the manufacturer’s AK line of midrange cordless-electric tools, is the second of two Stihl cordless tools reviewed here—and, at about $200, is moderately priced for a battery-powered trimmer.

The price for the straight-shaft trimmer includes a 36-volt, lithium-ion AK 10 battery and AL 101 charger, though we tested the trimmer with the beefier AK 20 battery we’d already had on loan from testing the Stihl MSA 120C-BQ chainsaw. (That product will not run on the AK 10.) Already have tools from Stihl’s AK line? You can buy the FSA 56 without the battery and charger for $50 less.

Revving up the FSA 56
As with the MSA 120C-BQ, the battery snaps snugly into place and has four LEDs indicating remaining power. Starting the trimmer takes three steps, one of them the usual safety lockout for the actual trigger, but the lockout itself has a lockout—a retaining latch you must release before anything else. Without a glance first at the manual, you might find the unit adult- as well as child-proof. But once you’ve done it once, you won’t forget it. You need to hold down only the trigger to keep the tool whirring.

The business end of the trimmer has a bump head for feeding line plus the usual metal blade in the deflector to keep line from spanning beyond the 11-inch cutting width. Not many years ago, a dual-line, battery-powered string trimmer was scarce. Now they’re fairly common, and this pair has an ample 0.80-inch diameter. We didn’t need to swap spools but ran through the process anyway and judged it as easy as in the video below. As with the unit itself and all Stihl products, you’ll find replacement spools only at a Stihl dealership.

The FSA 56, as tested, weighs 8.2 pounds, and we found it well-balanced and easy to operate along the perimeter of the test property. But the news gets better: With the lesser AK 10 battery, the one actually sold with the unit, the trimmer weighs only 7.3 pounds. The shaft is also adjustable by several inches, and you can adjust the angle of the front (loop) handle with a quick turn of a star knob.

Turf battles
We tested the FSA 56 on everything from soft, overgrown grass to a some stiff-stemmed weeds, with a persistent patch of ground elder providing much of the challenge. The dual lines ripped deftly through the grass and ground elder, though the heaviest growth likely accounted for the roughly 30 minutes we got out of the AK 20 battery before it began to cut out. (It’s rated for 34 minutes; the AK 10, 17 minutes.) Not that the trimmer didn’t slice through the denser patches. It did, but if you have a lot of thick weeds on your property, you might want to pay another $70 for a second AK 10, which would serve for another 15-17 minutes while the first battery charges.

Stihl claims that with the standard AK 10, you can “trim the length of five football fields on a single battery charge.” With most homes and their diverse plants and widths of the places the mower can’t reach, there’s no way to judge that claim. Still, we trimmed plenty of property on a charge—even accounting for fallen sticks, which add resistance, among the weeds we cleared. We even edged with the FSA 56, though we had to do it by holding the trimmer sideways; the cutting head can’t be rotated as with some other manufacturers’ trimmers.

As with the MSA 120C-BQ chainsaw, the charger took about 2 ½ hours with the AK 20. Buy the string trimmer in the usual way, with the AK 10 battery, and you’ll be up and running again in about 80 minutes.

A couple of caveats: We found no concerns about the battery life, but perhaps none arose since we used the higher amp-hour battery. Some customers on Stihl’s own site have complained about short battery life, along with problems getting replacement spools. For this second grievance, we advise you check before buying the trimmer that your local dealer stocks replacement spools for this product.

The verdict
With either battery on the FSA 56, you’ll be spending a lot of time charging it if you live in a woodsy neighborhood with lush growth around the edges. That, in fact, might be the concern of some buyers who’ve posted user reviews to Stihl’s website. In such settings, you’d be better off with a gas machine such as the $240 Stihl FS 56 RC-E.

But if you have modest weed growth along your property’s perimeter and don’t want to deal with the maintenance of a gas-powered weed whacker, the FSA 56 deserves your consideration. For power, ease of use, and light weight at the price, you can’t do much better in a cordless string trimmer.

Compact DeWalt Reciprocating Saw Fits Right In

DeWalt DCS367P1 Credit: DeWaltIf your property has trees, the need to chop branches into little pieces is frequent. For many such tasks, a chainsaw is more than you need—but with a bow saw, you’ll grunt through every stroke. In between is the sweet spot of the reciprocating saw, and these versatile tools are as handy indoors for studs, drywall, PVC and sheet metal as they are against tree limbs. The cordless DeWalt DCS367P1 20V Max XR Brushless Compact Reciprocating Saw, $250, has another plus: the four-position blade clamp DeWalt has been adding to its line.

Whether you call this tool a reciprocating or recip saw, a saber saw or a Sawzall (oops, that’s competitor Milwaukee Tools’ trademark), it’s the same beast, and the blade’s teeth usually face downward. You raise the keyless clamp, insert the blade’s shank and clamp back down. Then you’re set to go. But with the DeWalt DCS367P1, the vertical slot accepts a blade with teeth facing up or down. An adjacent horizontal slot, which forms the top of a letter T-shape, takes a left- (shown below) or right-facing blade. Why is this useful? Outdoors, you might never need the feature. Once you’re scrunched into a tight corner with scant room to work, a choice of blade orientation suddenly matters.

That versatility is part of the attraction, and the DeWalt’s compact size—just 13 inches from handle to shoe—helps in those awkward settings. The DCS367P1 is also fairly lightweight: just 6½ pounds counting its 20-volt, 5-Ah, lithium-ion battery.

Having a trim profile wouldn’t mean much if a saw couldn’t deliver. But from specs alone, the DeWalt seemed up to the task. Both its 1-1/8-inch stroke length and no-load 2,900 stroke-per-minute speed are above average for reciprocating saws, and the brushless motor is an improvement over older models that should mean more cuts per charge and longer product life.

Included with the saw is one DCB205 XR battery, a DCB115 charger and a kit bag.

Putting the DeWalt to work
We used the saw to slice through lumber, tree limbs and roots, PVC and sheet metal using wood- and metal-cutting blades from 5 to 8 inches. (You can use blades as short as 3½-inch.) As with any recip saw, the closest to pretty cuts you can get result when you can rest the pivoting shoe against what you’re cutting—a luxury you don’t necessarily have. Whatever the material, the DeWalt DCS367P1 made short work of it. A bright LED shines on your cut and stays lit for 20 seconds after you release the variable-speed trigger.

DeWalt DCS367P1 with blade Credit: DeWaltRun time isn’t especially relevant when the typical job for such saws requires just a handful of cuts at a time. So rather than measure the length of a charge in minutes, we made successive rough cuts of an untreated pine 4×4. The saw made it through 61 full cuts before fading out. The three-LED “fuel gauge” grants some idea of time remaining: When you’re down to one LED, you’re below 50 percent. Recharge when the last one goes out to avoid running the lithium-ion battery down too low—which would shorten its overall ability to take a charge.

With one particular job, removing a tree root that had worked its way out from beneath a wooden retaining wall, the choice of blade orientation came in handy. By installing the blade facing rightward, we were able to slice the root flush with the wall.

One knock against the saw is little vibration control. The main handle’s grip is anti-slip, but if you’ll be doing a lot of cutting with a hand on the rubberized handle, do yourself a favor and put on a pair of work gloves. (You should already be wearing goggles.) That rubber otherwise could cause blistering.

Should you need the saw for a lot of cutting at a time, the approximately 15-minute recharge time is very welcome. Want an extra battery all the same? A two-pack from Amazon, at the time of this posting, cost $149—a bargain compared to the $129 you’d pay for a single one at Home Depot.

The verdict
From its sheer power in a low-maintenance product, any reciprocating saw can quickly become your favorite tool. And whether you’re a contractor who needs a saw for tight places or a homeowner who wants muscle in a lightweight, compact product, the DeWalt DCS367P1 won’t disappoint you. The choices in cut direction, quick charging and breakneck speed are just part of this standout saw, and the brushless motor should help keep it among your arsenal for a long time.
