The chainsaw is an essential tool for cutting branches or felling a tree. The shape, size, and power of this device vary according to the working conditions for which it has been designed. Thus, there are pruning chainsaws, felling chainsaws, etc.
Despite its many variants, the chainsaw generally operates in the same way and requires similar precautions to be taken.
- The chain surrounding the blade of the chainsaw is equipped with teeth.
- The engine drives the chain around its support commonly called "bar". Generally, the length of the latter determines the power of the device.
- With more aggressive teeth, the user is more exposed to the risks of chainsaw kickback, blade backlash, etc. Therefore, equipment suitable for the work to be carried out is essential.
- The latest generations of chainsaws most often have safety systems like kickback protection, chain brake... However, it is always necessary to remain alert when handling this cutting tool.
Technically, a chainsaw is used to cut wood, branches, a tree, etc., but each job corresponds to a specific model.
- The all-purpose chainsaw is intended for small everyday tasks: cutting branches, logging, felling small-section trees... It has a guide of less than 45 cm.
- The felling chainsaw is equipped with a guide exceeding 45 cm. It is designed for intensive work on large trees. Generally, this device is quite difficult to handle due to its weight. Depending on the model, its cutting length can exceed 80 cm.
- The pruning chainsaw is more manageable due to its lightness. It has a cutting capacity of less than 35 cm and is thus suitable for pruning branches.
- The chainsaw is said to be gas-powered if its engine requires fuel to operate. It can also be equipped with an electric motor.
