21v brushless lithium battery electric chain saw 16-inch industrial grade large logging cutting electric chain saw 21V 无刷锂电电链锯 16 寸工业级大型伐木切割电动链锯

1. Product Features

1. This 21V brushless lithium battery chain saw features a high-power brushless motor, with a 16-inch guide plate suitable for cutting large-diameter wood, and it is a large-size model of the lithium battery chain saw.
2. No tool required for installation, removal, and adjustment—easy on-site tuning.
3. The automatic oil pump system continuously lubricates the chain guide plates.
4. The double handle is enlarged, and the thick wood cutting provides stable grip.
5. Glove guard with safety lock buttons for multiple protections.
6. Wireless lithium battery alternative to fuel-powered chainsaw, with no exhaust and low noise, suitable for use in forest farms and indoors.

2. Product Advantages

1. The 16-inch guide plate has a long cutting range, allowing it to cut large-diameter wood in one pass, and its efficiency is much higher than that of small chainsaws.
2. The high-power brushless motor experiences less speed degradation under high load, providing ample power for cutting coarse wood.
3. Compared to the fuel-powered chainsaw, the lithium battery version lacks a start pull rope, no mixed fuel, no exhaust emissions, and requires simple maintenance.
4. Automatic oil pumping and lubrication reduce dry wear on the chain.
5. Dual handle ergonomic design, stable for long-term use.
6. A fast-disconnect battery structure ensures continuous operation with alternate backup batteries.
