NEO-TEC NS892V1 Chainsaw Review

The engine is the reason to look at this saw. A 92cc, 2-cycle air-cooled full-crank engine rated at 5.2 kW, or 7 HP, has the torque to pull a long bar through large hardwood instead of stalling halfway in. That is the displacement class where a saw stops being a firewood tool and starts being a felling and milling machine.

Bar and chain out of the box

The saw ships with a 36-inch bar, 3/8-inch pitch, .063-inch gauge, 114 drive links and a full-chisel chain. That is a big-timber length, and it is also the length that lets you set the powerhead up for milling without buying a bar first. Full-chisel cutters are the fast-cutting tooth shape for clean wood.

Build materials

Magnesium-alloy parts are what you expect in this class: they keep a saw of this size manageable in the hands and hold up to the knocks of forestry work better than plastic covers would.

Parts and bar compatibility

The saw is compatible with MS660/066 and G660 parts, and with 36-inch bars in 3/8-inch pitch, .063-inch gauge and 114 drive links. In practice that means bars, chains and many components are easy to find, which matters on a saw you service yourself.

What comes in the box

You get the chainsaw head, the 36-inch bar and chain, premium spark plugs, a high-quality carburetor, a full-chisel chain, a quick-stop chain brake and a safety switch to prevent accidental starting.

What buyers on Amazon report

Amazon's summary of its customer reviews describes one buyer finding the saw an outstanding product that works well and offers good value, with performance and durability praised. One customer mentions it cut through a trunk with no problem, and another notes it rips through effortlessly. The ratings are strongly top-heavy, with the large majority at four or five stars and a clear minority at one star. Treat this as sentiment from owners, not as measured data.

The combination of 92cc, a 36-inch full-chisel setup and MS660/066-compatible parts is what this saw's specification buys you.

This is a big, heavy, loud saw. At 92cc with a 36-inch bar it is a two-handed, physically demanding tool, and it is not the saw for limbing small trees or for anyone who wants light and easy.

It expects an owner who does setup and tuning

The fuel mix has to be right, the carburetor has to be tuned, and the chain has to stay sharp, tensioned and oiled. That adds up to a maintenance learning curve and a finicky fuel mix, which can make the saw intimidating for beginners.

Not CARB certified

There is no sale and no shipping to California addresses; sales are restricted to non-California buyers. This is a hard limit, not a preference, so check where you live before you order.

Check service options before you buy

Check what service and repair support is available before you buy. Plan on sourcing parts yourself, which the MS660/066 and G660 compatibility makes possible.

The minority of poor ratings

Amazon's rating spread includes a meaningful share of one-star ratings alongside the positive summary. Weigh that honestly when you decide.

These are the figures that decide whether the saw fits your wood and your habits.

The fuel mix is the setup detail that matters most

The two ratios are tied to the oil grade: 25:1 with FB-grade oil, 40:1 with FD-grade oil. Match the oil to the ratio you mix, because running the wrong ratio for the oil in the can is the fastest way to hurt a two-stroke engine. Measure the oil rather than eyeballing it.

What the bar and chain figures mean for you

A 36-inch bar in 3/8-inch pitch and .063-inch gauge with 114 drive links is a long, heavy setup, so the saw balances toward the nose and you will feel the length at the end of a cut. The .063-inch gauge is the wider of the common gauges, which suits the long bar and the bigger engine.

The NS892V1 is also sold as the NS892V1-6 with a 28-inch bar and chain and as the NS892V1-8 with a 42-inch bar and chain. Both carry the same heavy-duty forestry design, 92cc, 5.2 kW / 7 HP engine and MS660 and G660 parts compatibility as the 36-inch version. The 28-inch bar has a 3/8-inch pitch, .063-inch gauge bar and 92 drive links; the 42-inch bar has a 136-drive-link bar and chain. A longer bar gives a longer cut and more reach, and it also makes the saw heavier and harder to handle, so pick the shortest bar that covers the wood you cut.
