Farmmac F070W Chainsaw Review

The F070W is a 2-cycle, air-cooled gas chainsaw with a 105 cc engine rated at 4.8 kW, or 6.5 HP, sold as a powerhead with an alloy solid bar. It is a clone of a long-established large-frame design, and its parts are compatible with MS070, 090 and Neotec NS8105 components.

The parts compatibility is a practical advantage. Bars, chains and many wear components follow a well-known pattern, so replacements are easier to source than for a one-off design.

Torque and big-wood capability. At 105 cc and 6.5 HP, the saw has the power to pull a long bar through large-diameter wood. Buyers on Amazon most often praise its performance and its power, and Amazon's summary of its customer reviews says buyers describe it as the most powerful tool they own, with one buyer noting it can take down trees.

Long bar options. The box includes a 36 Inch Alloy Solid Bar.

Build. The body is full magnesium alloy and the bar is an alloy solid bar. Amazon's summary reports that buyers find it the best-built tool they have.

Value. Value for money is one of the most frequently mentioned positive points among Amazon buyers. The displacement, the long bar and the magnesium build are what justify that sentiment.

Milling potential. The engine size and the long-bar options make it one of the few affordable powerheads that can drive a long bar in a milling setup. Milling still calls for a ripping chain, a proper mill, an auxiliary oiler and a second person.

Weight. It weighs 29.7 lb dry. Amazon buyers are divided on it, with several calling it super heavy. This is a two-handed, ground-level saw for big work, not a limbing or climbing tool.

Noise and vibration. A large-displacement two-stroke of this design class is loud and vibey. Hearing protection and hand protection are not optional.

Starting. Amazon buyers disagree on how easy it is to start. The saw rewards a correct cold-start routine and a properly tuned carburetor.

Durability. This is the weak spot in buyer feedback: Amazon's summary notes one customer reporting a gasket blowing out around the cylinder base, and the durability mentions lean negative.

Setup and tuning.

Not a one-saw solution. It is too heavy and too thirsty for general homeowner work.

The displacement and the 6.5 HP explain the torque you feel in big wood. The 29.7 lb explains the handling: plan your cuts at ground level. The 36-inch and 42-inch bar options explain why the saw appeals to people who mill lumber.

The F070W is sold in two bar lengths. The standard version carries a 36 inch alloy solid bar, and the F070W with 42 inch bar and chain (model F070W) pairs the same powerhead with a 42 inch alloy solid bar and matching chain.

Both versions share the 105 cc engine, 4.8 kW and 6.5 HP. Choose the 42 inch version for larger timber and milling work, where the extra reach matters more than the added bar weight and the extra power the saw must deliver.

A large bar, high torque and a heavy powerhead make kickback a real risk. Keep two hands on the handles, plant your feet firmly and clear an escape path before every cut.

• Wear hearing protection, eye and face protection, chainsaw chaps and boots.
• Do not fell or mill alone; have a second person on hand for large work.
• Follow the cold-start and warm-up routine, and never force a flooded saw.
• Check that the saw has a chain brake before you buy.
