The chainsaw on the battery is very handy, autonomous and light, the battery-powered chainsaw is used for small ad hoc wood cutting jobs. It is easy to use, non-polluting and quiet. With the tree electric saw this is important now.
The thermal chainsaw
The thermal chainsaw is powered by a 2-stroke petrol engine. It is used for routine, even intensive cutting work, made possible by its high power from 740 to 6,400 W. This chainsaw is autonomous, without electrical connection. On the other hand, it is noisier, polluting, cumbersome to handle and especially the thermal chainsaw requires meticulous maintenance. This chainsaw has a long enough blade (up to 90 cm) to be able to cut large trunks. It also exists in several displacements to adapt to the different levels of wood cutting work.
How to choose a chain saw?
The chainsaw model is first chosen according to the extent of the wood cutting work to be carried out. Other criteria must also be taken into account:
The length of the guide bar
The chain guide keeps and guides the chain in the movement of the chainsaw. The latter is composed of 3 types of links trainers with depth limiters, cutting gouges, and connecting pieces assembled using rivets. The length of the chain guide indicates the cutting capacity of a chainsaw: a chain guide of 30 cm, for example, allows cutting wood of 60 cm in diameter.
All chainsaws have a chain lubrication system, as it heats up at high speed and can deteriorate, using vegetable oil. The flow rate of this oil is the same on all chainsaw models but some give the possibility of adjusting this flow rate according to the hardness of the wood to be cut. For thermal chainsaws, the oil tank must be filled every time it is filled with fuel. For electric chainsaws, a level indicator is available to monitor the presence of this essential lubricant.
The shape of the front handle
The chainsaws, which are held with two hands, have 2 handles, one front, the other rear. The chain brake is located on the front handle, a powerful safety device that stops the chain in the event of kickback.
The shape of the front handle determines the possibilities of use:
- A front handle in the shape of a hoop allows you to work horizontally to cut down a tree or prune branches, but this position can limit the operation of the chain brake.
- A right front handle more particularly allows trucking work.
Safety and maintenance of a chainsaw
The chainsaw is the ideal motorized tool as soon as you have a garden made up of trees that must be maintained. But its use requires special precautions to avoid accidents and ensure its proper functioning. It is first of all very important to use a chainsaw with protections such as a visor helmet, work gloves, safety shoes or even clothes provided with anti-cut reinforcements. Preventive measures are also essential when using a chainsaw: do not use a ladder. always cut wood higher than his shoulders. do not put the chain saw on the ground.
Regular maintenance of a chainsaw is the guarantee of its proper functioning and maximum safety. Chain tension, lubrication and sharpening must be checked regularly. The guide bar must also be cleaned regularly, especially the lubrication holes.
