Criteria for the best chainsaw related to the gardener and use
The choice between all types of saws will depend on the type of work you will need to achieve, the diameter and the type of wood to be cut, frequency of use, budget and of course, the desired ease of use.
According to the types of work
Choose a powerful model, preferably a thermal chainsaw with a chain guide at least as long as the trunk diameter (if the trunk section is too great, however, you can cut several times). In the case of young trees with fine, tender trunks, an electric chainsaw, however, may be enough … In this case, check if you have a nearby electrical outlet or extension cord long enough.
Choose a model with a power between 1500 W to 2500 W (depending on the density-timber) with a length of chain guide 30 to 40 cm (depending on the diameter of the logs). Normally, an electric sector model should suffice to debit firewood provided, again, to have an electrical outlet nearby.
If it is possible to use all types of saws to perform the pruning, however it is strongly recommended to use a chainsaw to specific security reasons, especially if the tree is tall. From the ground, use a telescopic branches cut (called pole-pruner when the engine is placed at the bottom) which, depending on the model, the branches reach up to 4 m high. Since a ladder, use a pole pruner or saw a compact chainsaw (thermal or battery to not be bothered by the wire). Since the tree using a chainsaw pruner which is specially designed to be used with one hand leaving the second free you to grip branches.
Depending on the type of wood
The diameter and nature of the wood – its hardness – is also to be considered when buying a chainsaw.
Deciduous trees with an average density (chestnut, cherry, fruit …) or low (birch, alder, poplar …) are very easy to be cut. Hardwoods in very hard wood (hornbeam, beech, oak, ash …) or softwood (pine, maritime pine …) opposed by against a strong resistance to the chain, which can slow it down – or even sometimes stop – if the machine is not strong enough (and with a large displacement for thermal models).
According to user comfort
The ergonomics of a chainsaw is a determining factor in the purchase act. The body of the machine should be thin and well-balanced, even for occasional use…. When you hold it with both hands, it must not tend to tip forward or backward. Check also that it is not too heavy because it directly impacts its maneuverability and caused fatigue. Be attentive to the layout of the controls and handles the adjustment facility (chain tensioning without tools …) … and check if it has anti-vibration handles, especially if there is a thermal model. Finally, ask about the sound power (usually around 100 dB), especially if you have to use it in town. Know that heat engines are much noisier than electric models. you should choose the best chainsaw to ease the work.
NB: each 10 dB loosely translates to a volume felt twice as important
