Echo CS-271T-12 Gas Chainsaw Review

The saw is built around a small, light body that moves easily in tight spaces.

Light and compact

The dry weight is 6.6 lb, and that is the powerhead alone, without bar and chain. Fueled and ready to cut, it is heavier in the hand.

Built for climbing

A metal lanyard ring, a compact body and the top-handle configuration let the saw hang from a harness and be brought up into a tree. That is the job it was designed for.

Reliable, professional-grade engine

The 26.9 cc two-stroke uses ECHO's G-Force air pre-cleaner behind a rear-mounted tool-less air filter cover, so the filter is quick to check and clean in the field. Buyers on Amazon most often praise the saw's reliability and its cutting performance, and one customer notes it keeps running hard through a full day of work.

Easy starting for a small gas saw

The i-30 starting system cuts starting effort by around 30 percent, with a purge bulb and digital ignition. That is less pull on the rope, not a fuel saving.

Good oiling and chain access

The oiler is automatic, adjustable and clutch-driven, so it only oils when the chain moves. The chain tensioner sits on the side of the bar, which makes adjustment quick without removing the cover.

Durability and parts

An inertia chain brake and a vibration-reduction system are part of the build, and the warranty runs 5 years for consumer use and 1 year for commercial use. The 12-inch bar and chain combination is shared across many ECHO models, so replacements are easy to find.

The top-handle layout is a limit as much as a feature, and it is the most useful thing to understand before buying.

It is a top-handle saw

The saw is built for in-tree work by trained climbers. For ground-level cutting, a rear-handle saw gives more control and is the safer choice. ECHO's own documentation labels this range for professional use and warns against operating a chainsaw in a tree without specific training.

Small engine, modest power

26.9 cc is a limbing and pruning engine. It is not a firewood or felling saw. It cuts small branches and limbs at its own pace, and forcing it bogs it down.

Break-in takes time

ECHO specifies a break-in period of at least two tanks of fuel before any carburetor adjustment.

Fixed 12-inch bar

ECHO lists this model with a 12-inch bar only. There is no longer bar option for it.

Carburetor limiter caps

The carburetor ships with adjustment limiters, so tuning beyond the factory setting needs a dealer. Removing them voids the warranty and may breach emissions rules.

Altitude sensitivity

The carburetor is factory-set for use up to about 1,100 ft above sea level. Above that a dealer adjustment may be needed, and it must be readjusted if the saw is brought back down, or engine damage can result.

No case or kick guard in the box

The saw ships with tools. A kick guard, or safety tip, is sold separately, and ECHO's manual recommends it for beginners and novices.

The 6.6 lb figure is the powerhead alone. With fuel, bar and chain the saw is heavier in the hand, and that is the number to keep in mind when you compare it with what you expect to lift on a rope. The chain takes a 5/32 in file for sharpening.

The saw suits a narrow set of users, and the point is worth stating plainly.

Buy it if

You are a trained climber or arborist who cuts aloft on a rope and harness and wants a light, reliable, professional-grade top-handle gas saw. You are also well served if you are a carver who wants a small, nimble gas saw for detail work.

Skip it if

You are a homeowner who wants to limb fallen branches, buck firewood or fell small trees from the ground. A rear-handle saw is safer, easier to control and better suited to that work.

Think twice if

You are a beginner who has never used a top-handle saw. ECHO's own documentation labels this range for professional use, and the top-handle layout is unforgiving of poor technique.

A small two-stroke rewards a routine, and the saw's own manual sets most of it.

Starting

Use the purge bulb, choke and fast-idle as the manual describes, and let the saw idle briefly before you rev it.

Break-in

Run at least two tanks of fuel before any carburetor adjustment, per ECHO. The saw gains power as it breaks in.

Fuel

Mix 50:1 with 89 octane minimum and use fresh fuel.

Oiling

Check the bar oil reservoir, which holds 5.4 fl oz, at each fill. The clutch-driven oiler only oils when the chain moves, so a stationary saw will not oil the bar.

Chain

Keep the 3/8 in low-profile chain sharp with a 5/32 in file.

Air filter

The tool-less rear cover makes the G-Force pre-cleaner quick to check.

Altitude

The factory carburetor setting suits use up to about 1,100 ft. Above that, have a dealer adjust it, and have it readjusted if you move back down.
