The most important benefit of working with a chainsaw--rate --is rather clear. It would be tough to devote an whole day chopping your way through a woods using a handsaw, but you may certainly do this using a chainsaw.
A small primitive math demonstrates why a chainsaw is 5--10 times faster than a typical hand saw. Think how many boards of wood you can make out of one, trimmed tree backward: possibly fifteen or ten? Now consider how simple it's to saw through one plank using a handsaw; clipping through an whole tree will take you 10 times as long, assuming you do not run out of electricity or melt your chosen blade .
Let us attempt a more sophisticated quote. That usually means the chain should pass through the timber 600 days (30cm = 300mm plus it requires two chains moves to eliminate each mm). If you are using a strong chainsaw using a rotational rate of approximately 2800rpm (phone it 3000rpm to make the math simple ), the series will (theoretically) create 600 moves in only 20 minutes. In practice, it's going take a little longer. Let us say a moment.
How long could it take using a handsaw? Suppose that your saw has teeth exactly the exact same size as the chainsaw and assume it is roughly the exact same span as the chainsaw (and so half so long as the string ). You still must make those 600 moves through the timber. Perhaps you're superhuman: assume you can make a complete pass of this saw every second and maintain that rate constantly. In practice, it is going to require quite somewhat longer as you become tired, since the saw slides from its groove from time to time, and so forth.
Though chainsaws may be employed by any rather powerful adult (after appropriate training), they're nevertheless inherently harmful. (I have the guide for a Stihl MS270 chainsaw available with me as I write this and it is interesting to remember about 16 of those 64 pages--a quarter of the text--is dedicated to warnings and safety measures.) Chainsaw helmets with visors offer you some security; so also do chainsaw (manufactured from synthetic fibers like nylon, that snag up the chainsaw and deliver the machine immediately to a stop ).
Another huge issue with chainsaws is the sum of maintenance they want. A handsaw is superbly care free: the sawdust you create simply drops from the groove you are making. At a chainsaw, the super-fine dust may get trapped in the system and blend together with the string's lubricating oil to create a gunky mess which must be cleaned out frequently. Again, taking a look at the manual for the Stihl MS270, it is intriguing to see there is a full-page graph spelling out two or three dozen different checks and maintenance tasks you need to do before beginning work every day, or about a weekly, monthly, or yearly basis thereafter. So while it is accurate to noticed that chainsaws save time at the real chopping of wood, some of the time is, sadly, lost in upkeep!
