how to tell if chainsaw is dull

You should check the chips produced from cutting. If they’re thick, curved, and “shark-fin shaped”, it’s a sign that your chain is dull and needs sharpening.

Watch for smoke coming from the chain when cutting wood, which could signal that it is burning due to a dull chain. 

Here are a few indicators which may help you to know that your chainsaw is dull:

1. Chainsaw Starts Producing Sawdust Instead of Saw Chips

An effective way of making this determination is to observe the fine sawdust produced while cutting, as well as the behavior of the chain when in use. If, instead of processing thick and coarse look chips, the chainsaw produces downy-looking fine sawdust, it may be an indication that the blades are losing their sharpness. 

2. Chainsaw Chain Starts Pulling to One Side While Cutting 

If a chainsaw chain starts pulling towards one side, it could be another possible sign that the chain’s edge has gone dull. 

3. Chainsaw Chain Resists Entering the Wood 

The indication of your chainsaw being a dull blade is when the chain resists entering the wood. When this happens, it means your blade is not going through as easily as it should, and this is a sign that your chain needs to be sharpened again.

 4. Chainsaw Chain Smokes If You Forget to Lubricate

If you forget to lubricate on occasion and the chainsaw begins smoking, it may also indicate that your chain needs to be sharpened or replaced. Keep an eye out for these possibilities to ensure your chainsaw sharpener remains in tip-top condition. You can also use chain oil.

How Often Should I Sharpen the Chainsaw Chain?

According to experts, the optimal sharpening frequency varies depending on the type and intensity of work you are doing with the chainsaw. For general home use, sharpen your chainsaw at least once every two to three months. If you commonly tackle large wood-cutting tasks such as felling trees, you should sharpen your chain after every one to two days of use.

While sharpening the chain yourself is an option, it is best to take your chainsaw to a professional for this service. A professional can make sure that the cutting blades are evenly sharpened and properly balanced. Properly balanced blades will reduce vibration in the chainsaw, which helps to extend the life of your tool.

1. Cleanliness of The Wood You Are Cutting 

The frequency at which you should sharpen the chain of your chainsaw is largely determined by the cleanliness and hardness of the wood that you are cutting. If you are cutting wood that has a lot of dirt, sand, or other debris stuck to it, this can reduce the sharpness of your chain quicker.

2. Hardness of The Wood You Are Cutting 

Hard woods, such as oak or hard maple, will also dull the blade faster than softer woods, like pine. Therefore, if you are regularly cutting harder or dirtier wood, then you may need to sharpen it more frequently than someone who cuts mostly softwood. Generally speaking, though, it is best to sharpen every 10-15 hours of use for optimal results.

3. When the Chainsaw Chain Contacts the Ground 

Generally, the chain should be sharpened when it produces excessive smoke or sawdust, has difficulty cutting through wood, appears dull, or becomes noisy.

4. When the Chainsaw Chain Comes in Contact with Any Foreign Object

You should also sharpen your chainsaw’s chain whenever it comes into contact with any foreign objects, such as rocks, metal, nails, and other debris found outdoors. It is important that you inspect the chain before each use for broken cutter or any damaged teeth, which could be hazardous if used.

Sharp Chainsaw Blades Vs. Dull Chainsaw Blades: A Comparison

Let’s look one by one at how these two blades are different from each other.

1. Sharp Chainsaw Blades 

A sharp chainsaw blade is a saw blade that has been honed to a fine edge and will cut effectively through the wood. It can be identified by its smooth, even cutting surface that causes minimal effort when cutting. A sharp chain saw blade should also produce clean, straight cuts and minimal splintering or tearing of the wood’s fibers.

2. Dull Chainsaw Blade

A dull chainsaw blade has seen better days and will require more effort to use. This type of chainsaw blade may look chipped or jagged on the edges, indicating it needs sharpening or replacing. A dull chainsaw may cause irregular cuts and pull at the wood fibers while slicing through them, leading to unsightly tear-out and rough textures

How to Fix A Chainsaw Chain Which Is Not Cutting?

  • Firstly, you must assess the condition of the chain. Check for any bends or cracks in the links and ensure that all of the teeth are sharp and pointed correctly. If there are any bent or cracked links, replace them.
  • Next, take a file and sharpen the chainsaw teeth. Use a round file for filing each cutter tooth, and make sure to keep filing in the same direction until all of the teeth are sharpened. Once you have sharpened all of the teeth, place a drop of motor oil on each one to protect it from corrosion and wear.
  • After every use of the chainsaw, be sure to clean it thoroughly, including inside the chain casing. 
  • Also, if you are not using your chainsaw for more than a day or two, store it properly in a scabbard to protect the chain from dirt and other contaminants. Following these steps will ensure that your chainsaw is always in good working condition and ready for use when you need it.

Chainsaw Maintenance: Tips from The Experts

3. Indoor Storage of The Chainsaw 

It is important to be aware of how to store and lubricate the chainsaw. When keeping a chainsaw indoors, it should be stored away from heat sources, as this may cause damage to the machine. Additionally, all fuel must be drained before storing the chainsaw. This will allow the engine to cool down and reduce the chances of fire hazards.
