Can you use a chainsaw in dirt?
Correspondingly, can you use a chainsaw to dig a trench?
Yes, you could trench with a chainsaw, for a while at least.
Furthermore, can you use a chainsaw to cut roots? After you make a few cuts, turn your chainsaw off and see if you can remove any loose, large clumps of wood or dirt. Remember, you can leave some wood below the dirt. Also, you can cut large roots out by sawing into the ground vertically, and then by prying the root out with a shovel or pickax.
Besides, is it bad to run a chainsaw without a chain?
Safety wise a chainsaw without the chain is still VERY dangerous. The bar will get an edge from the chain passing over it. Not to mention swinging a flat piece of steel around. IMO accidents can and do happen and any haunter using a real bar from a chainsaw is gonna wind up getting hurt over the practice.
How many times can you sharpen a chainsaw chain?
Depending on usage, a chain can usually be sharpened 3 to 5 times max.
