How to sharpen a chainsaw by hand with a file

Having a sharp chainsaw is very important when you want to cut down a tree because using a dull chainsaw can be very dangerous and may even ruin the chain.

To start it is imperative that you make sure the chainsaw is disconnected from power and completely shut off. Place the chain side of the chain saw in a vice grip and make sure that the chain is free to move, that its not touching the grip on the top or bottom.

Check the diameter of the teeth on the chain to determine the size file that you will need to use. Placing the file in to the curve of the tooth, hold it at the same angle of the blade, usually a 30 degree angle. Using a little bit of pressure slide the file away from you, against the tooth. If you have a guide you should use it to make sure that the angle is right. Repeat this for every second tooth on the chain, advancing the chain so that the one you are working on is always on top.

When you have finished all the teeth in that direction (every other blade) open the vise grip and turn the saw around. Look at the clearance of the rakers, depth of the gauge of the teeth, they should be 1/10 of an inch lower than the cutter. If they are too tall you will need to file them down using a flat mill file. Using the same motion file down the rakers until they are 1/10 of an inch lower than the the cutter's hook.

You should wear gloves when working with a chainsaw because they are very sharp. If you don't know what you are doing maybe you should consider going to an expert before embarking on your own adventure.

when go to cut engine is runnig but chain stops when touch the tree


Hi Pam:
Using chain saws takes a bit of getting used to, and it can be DANGEROUS.
- The chain must be sharp to be able to cut properly, and a sharp chain "bites" into the wood.
- Before you touch the chain into the wood, you have to speed up the engine. This takes some getting used to.
- Try this technique: With the chain about an inch above where you want to cut, squeeze the throttle about half way so the chain is spinning. Touch the chain to the wood and increase the engine speed as the chain starts to cut. The harder you cut, the more power you need to apply.
After a while it gets to be second nature.
Work Safe, and get an experienced friend to help with some "hands on" coaching.
Cheers.

is it dangerous to use a chainsaw with a dull blade?


not to scare you, but most chainsaw accidents occur due in some part to a dull blade. if the blade is not sharp, it may be more prone to getting caught in the wood which can cause it to buck when it comes free. this is very dangerous, so keep the blade sharp- anyways it will make the cutting go smoother

My poulan 18 inch chain saws blade turns but only cuts in about an inch and won't go any farther. It's two days old and worked fine cutting the first 2 trees down.


It sounds like the chain does want sharpening, it depends on what you are cutting ( type of timber, dirty timber,burnt timber etc ) as to how long before it needs sharpening, if the chain comes into contact with the ground below the tree it will lose its edge instantly.

how do you remove the sprocket and clutch assembly


Article: Fixing a Broken Chainsaw

Having a broken chainsaw is an inconvenience. Having one that works when you need it is important! Chainsaws are useful tools for tree pruning, cutting firewood, and carpentry projects, but are not so useful if not properly maintained. It can also cost a great deal of money to get a broken chainsaw repaired. You can save a lot of time and money by repairing it yourself. For chainsaw repair you will need a blanket or large cloth, a chainsaw tightening tool, files to sharpen the blades, and any necessary replacement parts.

My Chainsaw's Engine Does Not Start

If the engine will start at all, you might have a bad starter switch. Check to see that all connections to the starter switch are secure. Is the power cord cut or broken? Check to make sure that you have a proper power line connection. If all checks out except for the switch, go ahead and replace it. You may want to consider whether you are using the appropriate fuel mixture.

My Chainsaw Smokes

If there is smoke coming from the chain, it could be an indication that there is not enough lubrication. Without the proper lubrication, the chain and chain bar can become seriously damaged. Make sure there is oil in the reservoir. When you start the saw, the automatic oil pump should lubricate the chain and bar. To see if this is a problem, hold the saw tip over a light-colored surface, hit the throttle and look for oil spatters on the chain bar. If you see no oil splatters, turn the saw off. Remove the chain guide bar and see if the oil discharge slots are clogged with sawdust. Clean out the sawdust and restart the saw to check lubrication again.


The Chain Skips or Jumps

If the chain skips or jumps during operation, check the engine drive sprocket to make sure it is not worn. If you have a worn sprocket it will not allow the chain to sit properly. Also, check to make sure the chain tension is set correctly. Setting the chain tension is a part of continuous operation. However, a dull or damaged chain may also cause the skipping and jumping.

My Chainsaw Isn't Cutting Properly

If the saw cuts at the wrong angle or shoots out a lot of sawdust, you probably need to sharpen the chain. A dull chain can be very dangerous. It can cause a kickback or chain jump that might break the chain and release pieces that could harm to the operator. If your chain is very shiny, you need to examine each cutter for damage. Use a file to sharpen the cutters.

The Chain Continues to Move or Stops

If the chain continues to move while the engine idles then you should check to make sure the idle is not set too high. If it stops while cutting, see if the brake is engaged.

My Chainsaw Loses Power

If the saw loses power while operating, check to make sure all electrical connections are secure. Any break in current may cause the saw to decrease in power, stall or shut down altogether.

When maintained, chainsaws are a great asset to any tool collection. Consult your user's manual for questions specific to certain manufacturer types.

I'm using a Poulan 3416 and it's simply not cutting my neighbor and I used it last weekend to cut up fallen trees but it doesn't cut at all now?


It may sound oversimplified but....is your chain sharp? Is the chain on backwards?

When cutting you should be getting nice big chips from the cut. If you are getting more "dust" than chips the chain is dull and needs to be resharpened.

There is no set "time" to sharpen a chain,but you will only get a few hours of cutting before the chain dulls. In soft wood like pine you can go longer. In hardwood like oak or locust you may get an hours worth of cutting. If the bar digs into the ground or hits a rock it's time to sharpen right then because the chain will be dull.

I always carry an extra chain or two just for emergencies like hitting a rock or some wire in a tree.
