Understanding the basics of a chainsaw

To understand why your chainsaw may not be starting, its best to first understand basic mechanics that are found inside the chainsaw.

Though there are different models of chainsaws, whether it’s a gas or electric model, they all use the same concept to operate. They all have a chain with sharp teeth used to cut wood or other materials.

The chain is turned by gear wheels which are found inside the motor allowing it to run smoothly along the guide bar. Inside a gas engine is a piston that moves in and out of the cylinder that helps the crankshaft to turn gears hence causing the chain of the saw to spin.
