There are two main elements to the workings of a chainsaw…
- The motor/engine. The motor or engine can be either electric or petrol
- The chain. The engine powers a rod, which moves a crankshaft, which in turn operates gears, which are connected to sprockets that spin a chain around on a guide bar. The chain is metal, a little similar to a bicycle chain but fitted with tough, sharpened teeth. The guide bar acts in the same way as a flywheel, with the chain revolving around it at speed.
In addition, there are three elements to the efficiency of a chainsaw…
- Engine power
- Chain speed
- Cutting blade quality
The balance between these three will dictate how effective your Chainsaw is, when it comes to carrying out the work you want to do.
