Troubleshooting An Electric Chainsaw That Won't Cut

why is my electric chainsaw not cutting

If your electric chainsaw is not cutting, there are several potential issues to consider. Firstly, ensure that the chainsaw is receiving sufficient power by checking your power source, whether that's a battery or an electrical outlet. Next, inspect the chain for any signs of dullness or damage, as a dull chain can cause the engine to work harder and lead to excessive wear. If the chain appears to be in good condition, check the tension by lifting the chain while the chainsaw is at rest; the tension may be too tight or too loose, affecting the chain's ability to rotate and make proper contact with the wood. Additionally, the chain bar might be bent or worn out, impeding the smooth movement of the chain. Finally, the clutch pads and band should be in good condition and properly adjusted to ensure the chainsaw's cutting function.

The chain is dull or damaged

If your electric chainsaw is not cutting properly, one of the most common issues is a dull or damaged chain. This can be caused by a variety of factors, including improper chain tension, hitting nails or other metal objects, cutting dirty wood, or simply prolonged use without regular sharpening.

To address this issue, it is important to first inspect the chain for any visible signs of damage, such as bent or broken teeth, cracked or missing drive links, or damaged rivets. If the chain is damaged, it will need to be replaced. However, if the chain appears intact, it is likely that the issue is due to dull cutting teeth.

The chain is not properly lubricated

If your electric chainsaw is not cutting, it could be because the chain is not properly lubricated. Lubrication is essential for the efficient functioning of a chainsaw, and a lack of it can lead to increased friction and wear on the chain and other components.

To ensure proper lubrication, it is important to use the correct type and amount of chain oil. Chainsaw manufacturers typically recommend a specific type of oil that is designed to work effectively with their products. This information can usually be found in the user manual or by contacting the manufacturer directly. It is also crucial to fill the oil reservoir regularly, ideally each time the fuel tank is refuelled. This ensures that the chain remains adequately lubricated during use.

One way to check if your chainsaw is properly lubricated is to perform a simple test. Run the saw and point the bar towards a piece of cardboard on the ground. Give the saw a few revs and observe if any oil is flinging off and accumulating on the cardboard. If you see oil on the cardboard, it indicates that the chain is likely receiving sufficient lubrication.

In addition to proper lubrication, it is important to maintain correct chain tension. A chain that is too tight can hinder its movement, cause binding, or even lead to breakage. On the other hand, a loose chain that hangs off the bar may not make good contact with the cutting surface, affecting its cutting ability. Adjusting the tension by tightening or loosening the adjustment screw can help ensure optimal performance.

If your chainsaw is not cutting properly, it is important to troubleshoot and identify the root cause. In addition to lubrication and tension issues, other factors such as a dull chain, improper installation, or a worn-out chain bar could be contributing to the problem. Regular maintenance, including sharpening or replacing the chain when necessary, is crucial to ensure the safe and effective operation of your electric chainsaw.

The chain is mounted backwards

If your electric chainsaw is not cutting, there could be several reasons. One common issue is that the chain is not mounted correctly. Indeed, mounting the chain in the wrong direction is a common pitfall, even for experienced chainsaw users.

If your chain is mounted backwards, the cutters will not bite into the wood, and you will end up with smoke instead of actual cutting. To avoid this, the sharp edge of the chain should face outside or upwards when wrapping the chain around the guide bar. The drive link, cutter, and guide should always come in this specific order. If the guide comes before the chainsaw blade, then the chain is backward.

Additionally, the blades should rotate above the chainsaw bar, with the bar situated on the left side, spinning in a counter-clockwise direction. This puts the cutting edges facing away from the motor engine. If the chain is moving in the backward direction, then it is positioned incorrectly.

To avoid accidental damage to the machine, it is essential to mount the chain in the correct direction. This basic maintenance step will ensure the longevity and efficient performance of your electric chainsaw.

The chain does not have the proper tension

If your electric chainsaw is not cutting properly, one possible reason could be that the chain does not have the correct tension. Chainsaw chains can stretch and loosen over time, and if the tension is too loose, the chain may not be able to grip the wood and make a clean cut.

To check if the chain tension is the issue, inspect the chain to see if there is any

The power source is insufficient

If your electric chainsaw is not cutting, one of the first things to check is whether it is receiving enough power. If your chainsaw is sputtering, dying, or simply doesn’t feel as powerful as it should, then the issue may lie with the power source.

If your electric chainsaw is plugged into an outlet, check that the extension cord is rated for the correct ampacity. If your chainsaw is battery-powered, ensure that the batteries are fully charged. Rechargeable batteries tend to have a limited lifespan, so older batteries may not hold a charge for as long as they used to.

If your chainsaw is receiving sufficient power but still isn't cutting, then the problem may lie elsewhere. For example, if the chain is spinning but not cutting, or the chainsaw is not cutting straight, then you need to address the chain itself. A dull chain is a common issue with chainsaws and can usually be fixed by sharpening or replacing the chain.

If your electric chainsaw is still underperforming even with a sharp chain and sufficient power, there may be other factors at play. For instance, the type of wood or the size of the tree you are trying to cut may be affecting the chainsaw's performance. Harder types of wood will naturally be more challenging to cut and may require a more powerful chainsaw. Additionally, cutting through thicker tree trunks will demand more power from the chainsaw.

In some cases, the power source may be insufficient due to internal issues within the chainsaw itself. If the motor or internal wiring is faulty, it may not be able to draw enough power to operate effectively. In such cases, it may be more economical to replace the entire chainsaw rather than pay for internal repairs.

Frequently asked questions

First, make sure your chainsaw is getting enough power. If the chain is not turning, or not turning quickly enough, check your power source. If your chain is spinning but not cutting, address the chain itself. The most common cause of a chainsaw not cutting properly is a dull cutting chain. Try sharpening or replacing the chain.

A dull chain is characterised by fine sawdust falling as you cut, rather than small wood chips. You may also find it difficult to keep your saw cutting evenly.

To sharpen a chain correctly, you need to get the cutting angle, cross angle, chisel angle (or file depth) and raker depth just right. If you're sharpening by hand, there is a gauge available that sits on top of the teeth, allowing the raker to protrude through and indicate the amount to be removed.

The chain may not have the proper amount of tension. If the adjustment screw is too loose, the chain may not make good contact with the wood. If the chain is too tight, it may not rotate at the proper speed. The chain bar might also be bent or worn out.
