Chain saws are used differently by different users. Lumberjacks use them to fell huge trees or cut logs. Backyard gardeners use them to prune tree branches. Artists use them for woodcarving. What they will look for in a chain saw will differ greatly. Still, there are a few things that all potential chain saw buyers must keep in mind.
The first thing that you have to remember is that a chainsaw is a very powerful equipment and that the more powerful it is, the more difficult it is to handle. You do not want, therefore, a chain saw that delivers capabilities far beyond your needs. If you need one only for the trimming and pruning of trees in your backyard, you can settle with electric powered saws, with perhaps a 16-inch bar length. If you work in the forests cutting timber, you want a gasoline-powered type, as this delivers more punch, and perhaps one with a longer bar length.
As far as power is concerned, therefore, what you should look for in a chain saw is totally dependent on what you plan to use it for.
Regardless of your power requirements, you want a chain saw that you can handle with as much comfort as possible. All chain saws vibrate, although the intensity of the vibration varies with the power output. You will want, therefore, one that has springs or rubber pads where the handles are attached to the chassis. These will help absorb the vibration from the engine, the movement of the chain as it slides along the bar, and the cutting of the teeth into the tree.
Some gasoline-powered models feature a quick-start electronic ignition, thereby reducing the pulling force that has to be applied to the cord needed to start the engine. This is a convenience that you want to have in your chain saw.
A model with an automatic chain oiler would also make life easier for you. The chain has to be oiled at regular intervals for it to function smoothly, and thus cut through wood more efficiently. Older models are equipped with a manual pump to accomplish this, but there are new models that come with an automatic chain oiler.
The constant use of a chain saw often results in the greater slack of the chain. To keep the saw functioning efficiently, the chain must be readjusted to its proper tension. You want, therefore, a chain saw that incorporates a quick-adjust chain feature that will enable you to perform this task with built-in levers or knobs, instead of having to reach for other tools.
You also want a chain saw that limits its carbon monoxide emissions. There are models available in the market today that are fitted with filters through which fumes must go through before being released into the air. Remember that you will be holding the saw close to you and that you will be breathing in its exhaust fumes.
Finally, a carrying case for your equipment would also be a plus.
