You should not cut roots or anything that's embedded in the dirt with a chainsaw. Cutting in dirt dulls the chainsaw very fast, so you will need to learn to sharpen your saw, send it to a professional for sharpening, or replace it afterwards if you do so. You should also avoid cutting power lines.
Never operate a chainsaw that is damaged or has disengaged safety devices! Check all bolts, handles, and the chain for damage and proper tension. Make sure that the chain is sharp and the lubrication reservoir is full. Fuel the saw at least 10 feet away from ignition sources.
CUTS: The most common accident resulting from a chain saw. Most cuts result from a “kickback”. A saw can “kickback” in less than 1/5 of a second. This leaves the operator with no reaction time.
Avoid sawing from the bottom up, i.e. with a “pushing chain”, because this can push the chainsaw back towards you. Don't use a chainsaw above shoulder height, instead keep it below waist level. Make sure that the tip of the guide bar does not hit the ground or objects such as branches, the trunk, tools, etc.
Keep your hands on the saw's handles, and maintain balance while operating the saw. Proper personal protective equipment must be worn when operating the saw, which includes hand, foot, leg, eye, face, hearing and head protection. Do not wear loose-fitting clothing.
Install a safety tip that covers the nose of the guide bar on the saw to prevent contact with the kickback zone. The tip must be removed for making bore cuts (pocket cuts) or for cutting wood thicker than the length of the guide bar. Wear any required personal protective equipment.
Cutting #HDPE with a chain saw is a common field practice. Clean cuts make the facing process quicker. Experienced contractors use "dry saws" so residual oil does not end up on the pipe face.
Consider the need for eye protection from flying debris created by the chainsaw and other hazards such as branches. Glasses may not stay on the head as well as goggles for working at height.
According to the U.S. Consumer Product Safety Commission, the average chainsaw injury requires 110 stitches. And the CDC states that medical costs for chainsaw injuries amount to at least $350 million, every year. OSHA ascertains that, annually, there are around 250 chainsaw-related deaths.
The Kickback Danger Zone
When this area of the bar touches an object like a branch or log, there is high likelihood that a sudden kickback reaction will occur. The larger the bar nose size, the higher the potential for chainsaw kickback.
It ultimately comes down to the factors listed above (especially maintenance). That being said, you can expect a quality chainsaw to last you at least 10 years or more. But if you take care of it, I know people who have saws that have lasted 20-30 years and even longer.
Keep some distance between your legs and the guide bar. Bend down to maintain distance. Cut on one side, then the other to avoid moving the guide bar in front of you. Never cut with the chain saw above shoulder height (figure 4-3).
Disadvantages of Electric Chainsaws
Lack of mobility is a drawback of corded saws. If you're using a corded electric model, you'll want to buy an extension cord. Even with the cord, you will be limited in how far you can go. If you need room to roam, cordless battery-powered chainsaws will do the trick.
Hitting an unexpected nail or rock has the potential to cause serious damage to a chainsaw chain. It's important that all the teeth on a chain are uniform length to prevent increased vibration and the chain 'snatching' mid cut.
Chain Not Cutting
If the chain is sharp, but doesn't feel like it is cutting then the depth gauges or rakers need to be lowered. This is the “shark fin” shape directly in front of each cutting tooth. It's purpose is to limit how deep the cutting tooth dives into the wood.
The chain on the chainsaw will get dull fast if it comes into contact with sand, dirt, rocks and nails. Make sure to avoid all these hazards when using the chainsaw. If you do not, the lifetime of the equipment will be affected. For dirty conditions, you should use a specific type of saw chain.
Generally speaking, the chain should be a little loose on the chain saw guide bar, but not loose enough that the drive links come out of the bar nose. The bar links should feel like they are raising up, but not actually come out of the guide bar.

The three best types of saws for cutting thick plastic are a fine-toothed saw, a jigsaw, and a table saw. A fine-toothed saw works best for precision plastic cutting. If you need to make multiple non-linear cuts, this saw will serve you best. Fine-toothed saws also yield the smoothest cut.
Unique cordless chainsaw is ideal for cutting PVC and ABS pipe. Long-lasting chain blade with 15 teeth per inch cuts 4000 pieces of 4in. PVC pipe with minimal oil required.

The main causes of crooked chainsaw cutting are the chain and guide bar, for example if: The length, i.e. wear of the left and right chain teeth is uneven: this can happen when one of the sides hits a stone or piece of metal.
