Neo-Tec NH8120 Chainsaw Review

The NH8120 is built around a large engine and a long bar, and most of its strengths follow from those two facts.

Power for large-diameter timber

The 120 cc engine makes 6.2 kW at 9,000 rpm, or 8.4 hp. That is the top end of what a gas chainsaw buyer will run into, and it is what lets the saw pull a long bar through big hardwood instead of stalling in the cut.

Reach for felling and milling

The 36-inch guide bar and its 114-drive-link, 3/8-inch pitch, 0.063-inch gauge chain give the reach that large felling cuts and milling setups need, where bar length is often the limit on what you can cut.

Built for sustained load

A full-crank engine and magnesium-alloy parts point to a saw made for continuous heavy cutting rather than the occasional afternoon job. The 2200GS high-speed magnetic induction flywheel is part of that same heavy-duty layout.

Adjustable oil pump

The oiler can be tuned to the bar and the work. That matters most when you run a long bar or mill lumber, where the chain needs a steady, generous supply of oil.

Starting and field maintenance

A Quick Start feature makes a 120 cc engine easier to pull over. The side-mounted chain tensioner, the quick-release cover and the quick-release air filter with centrifugal air cleaning speed up the checks and cleaning you do between tanks.

Low vibration and a complete setup

It arrives as a complete setup: the chainsaw, the 36-inch bar, the chain, a spark plug, a carburetor, an ignition coil, a flywheel and two extra sprockets.

The limits of the NH8120 are the flip side of its size, and they matter as much as the power.

It is a very large, very heavy saw

A 120 cc gas chainsaw with a 36-inch bar is a two-handed, ground-based machine. It is the wrong tool for limbing, pruning, small trees or any cut made overhead, and it is not something you carry around all day.

It demands experience

This saw is built for professional loggers, arborists and sawmill operators. That much power and bar length carry real kickback risk, so the saw calls for proper technique, full protective gear and a clear head. A beginner should not start here.

Fuel and bar oil go fast

A 120 cc two-stroke working hard drinks mix and bar oil quickly. Plan on carrying fuel and oil to the job rather than expecting one tank to cover a long session.

The order arrives in two boxes

Each order ships in two separate packages. Check both boxes on delivery before you start assembling, to make sure nothing is missing.

It is a specialist tool

For firewood from medium logs or the odd storm cleanup, this saw is more machine than the task needs. The weight and the fuel use then become drawbacks instead of strengths.

These are the figures a buyer actually uses, as the product sheet lists them.

In practice, 120 cc and 8.4 hp put this saw in the big-timber and milling class, where the engine has to keep a long chain moving through dense wood without bogging. The 36-inch bar and the 3/8-inch, 0.063-inch chain suit large felling cuts and milling rigs, where a shorter bar simply cannot reach across the log. The adjustable oiler and the full-crank engine are what let the saw keep working under that sustained load, and together they are what justify its standing as a heavy-duty professional-class machine.

The NH8120 suits a narrow group of users, and it is worth being honest about which side of the line you fall on.

Buy it if

• You work as a logger, arborist or sawmill or milling operator.
• You regularly fell large-diameter trees or run a milling setup that needs a long bar and big power.
• You are experienced with large gas saws and have the protective gear and technique to run one safely.
• You want a complete 36-inch big-timber saw out of the box.

Skip it if

• You are a first-time or occasional chainsaw user.
• Your work is pruning, limbing, small trees or light firewood.
• You need a saw you can carry and handle for hours.
• You want a general-purpose homeowner saw.

This is a specialist big-work saw. Buying it for small jobs means paying for capability, and carrying the weight, that you do not need.

The ratings for the NH8120 on Amazon are almost entirely positive, with the large majority of them at five stars and few low ratings among them. That pattern fits a saw bought by people who already know they need a 120 cc machine for big timber or milling.

A few things are worth checking before you buy. Make sure the fuel and oil caps thread on straight and seal without seeping, and inspect the starter, the caps and the carburetor as soon as the boxes arrive.

A 120 cc saw with a 36-inch bar rewards a careful first session and punishes shortcuts.

Protective gear and technique

Keep both hands on the handles, stand clear of the kickback zone at the bar tip, and stop cutting when you are tired. If a tree is leaning toward a structure or a power line, call a professional rather than taking it on.

Fuel and oil habits

Carry spare mix and bar oil to the job, because a 120 cc engine working hard goes through both quickly. Keep the bar oil reservoir topped up.
