Boer BEZZ-581 Petrol Chainsaw
The Boer BEZZ-581 is a petrol chainsaw from the Zhizao series, made in Wuyi. It runs an IE58F engine of 54 cc and 2.5 kW, idles at 2800–3200 r/min, reaches 13000 r/min at high speed and takes a 25:1 fuel mix. You can order it with an 18- or 20-inch guide bar. Before you order, ask Boer for the chain specification for your bar, the saw's weight, its noise and vibration figures and the test reports your market requires.

The saw in the photographs and the data table
Four product photos show a red saw with Zhizao branding. The text adds the engine and bar figures. The displacement field reads 54 cc; the 581 in the name does not mean 58 cc.
Each bar length needs its own bar and chain part numbers, and the page gives no pitch, gauge, drive-link count or operating weight. Ask for a nameplate photo and revision sheet linking this engine to the cutting set you will receive. The neighbouring BEZZ-681 has its own figures.

Matching the saw to your cutting work
Choose the 18- or 20-inch setup with Boer based on the timber you cut and how you reach it. Bar length alone tells you neither the safe log diameter, the cutting rate nor how long the saw can run without a break. The page gives 2.5 kW with no test condition, and lists idle and high speed separately.
Get the manual, weight and handling figures, then test a sample saw on your own wood. Record the engine and build, bar and chain, the timber and the conditions, and compare the cuts. Running the same test on a NONGKE NK-8820 Chainsaw or a Remo RM-CS3800H Petrol Chainsaw gives you a side-by-side result. Bars, fuel mix and the import documents for petrol saws are covered in our handheld garden power tools guide for importers.

Buyer questions
Is the BEZZ-581 a 58 cc saw?
The model table lists 54 cc. BEZZ-581 is the model name and does not encode displacement. [1]
