Chain Saw Cutting Problems


Chain saws are wonderful tools when they are cutting properly. Most people know that when a chain saw gets dull it does not cut very easily, and in fact can become quite dangerous. But, there are a number of other problems that can cause your battery chainsaw to cut poorly. Most of these issues can be traced back to improper sharpening procedures or poor maintenance.

When you're cutting with your chain saw, if it cuts crooked or at an angle this is generally an indication that the teeth have been improperly filed. Either they were filed at the wrong angle, or every tooth was not filed the same amount and with the same pressure. If filing is not the cause of a chainsaw pulling to one side or the other, then it could be the bar or the sprocket at the far end of the bar are in poor condition and need maintenance or straightening.

If you have a newly sharpened chain saw and it dulls quickly, usually this is caused by thin cutting edges resulting from too much file pressure or low angle when sharpening your chain saw. Your chainsaw will need to be refiled using less pressure, as well as lowering the angle of attack and checking the height of the depth gauges.

If the chain grabs and cuts rough the saw sharpener probably induced a forward hook on the teeth as a result of too much pressure from the top of the file. A good indication that the depth gauges are set incorrectly is when the chain digs too far into the wood. You will need to lower the height of the depth gauges in most cases. If you detect overheating of the chain you may not have enough bar oil, or the saw sharpener created a backslope on the teeth during the last sharpening.

Drive link problems on the chain can result in severe problems like the chain jumping off the bar. Incorrect chain tension can cause this, and you may have to replace bent drive links on your chain. Also, excessive chain chatter can be caused by improper sprocket fit, and result in front or back peened drive links.

Whenever you identify these kinds of cutting problems with your chain saw you should immediately remove the bar and chain from the saw and inspect carefully. There are usually only a couple of nuts to remove the chain and separate the bar from the saw. This will allow you to inspect the parts for dangerous defects and keep your saw in good condition.

Here are some chain saw safety tips you need to know.

1 - Before Starting a Chain Saw

The first thing you need to do is make sure that all of the controls are functioning according to manufacturer's specifications. You should examine the controls, check the chain tension, and make sure all bolts and handles are tight and ready to go. You will also want to make sure the saw's fuel tank is full with the correct fuel, and that your saw is full of bar and chain oil. Always be sure to add fuel to your saw at least 10 feet away from any ignition sources(including cigarettes). The last thing anyone needs is to get burned. Always wear the proper protective gear. This would include a safety helmet with a screen face shield, gloves, a thick upper garment, boots, and chaps. Loose fitting clothing is something you need to avoid.

2 - Starting the Saw

Always make sure your saw is placed on the ground when you start it. You never want to drop start a chainsaw because if the chain-brake is off and the saw starts it will easily cut through your skin and bones; potentially causing a fatal wound. Apply the chain-brake, then start the saw.

3 - Operating the Saw

If possible never work alone. If something happens while you're alone you could be in big trouble. Always make sure while the saw is in operation you have a firm grip on the saws handles, and that you have a solid stance. Clear any and all debris from the area before you begin cutting. This includes dirt, nails, other wood, any anything that could possibly harm you or your equipment. If you need to move either turn off the saw or engage the chain-brake. Never cut with the tip of the saw. This could lead to kickback, meaning the saw may fly back at you and cut you.
