Most Common Chainsaw Problems and How to Solve Them

Chain Won’t Move

Possible Causes:

1. Chain tension too loose. If the chain tension is too loose, it will not move when the chainsaw is in use. This can be due to the chain stretching over time or not being tightened properly.
2. Chain tension too tight. On the other hand, if the chainsaw chain tension is too tight, it can cause the chain to bind and prevent it from moving.
3. Bar oil system clogged. The bar oil system is responsible for lubricating the chain and bar as the chainsaw is in use. If the bar oil system becomes clogged, it can prevent the chain from moving properly.

Step-by-step guide to fixing a chain that won’t move:

1. Check chain tension: Lift the chain away from the bar using your finger to check the tension. If it lifts up more than 1/8 of an inch, it is too loose and needs to be tightened. If it doesn’t lift at all, it is too tight and needs to be loosened.
2. Adjust chain tension: Use the chainsaw’s tensioning screw to change the chain’s tension. Turn the screw in the direction indicated in the chainsaw’s manual until the chain tension is correct.
3. Clean bar oil system: Remove the bar and chain from the chainsaw and use a clean towel to wipe away any dirt or debris before cleaning the bar oil system. Check the oil reservoir and make sure it is clean and free of debris.

Engine Won’t Start

Possible Causes:

Dirty air filter. A dirty air filter can restrict the airflow to the engine and prevent it from starting.

Fuel system clogged. A clogged fuel system can prevent the engine from getting the fuel it needs to start.

Spark plug issue. A malfunctioning chainsaw spark plug might make it impossible for the engine to start by failing to generate the spark necessary to ignite the fuel.

Step-by-step guide to fixing an engine that won’t start:

1. Check air filter: Remove the air filter from the chainsaw, then inspect it for any evidence of dirt or debris. If it’s unclean, either clean it or get a new one.
2. Clean fuel system: Drain the chainsaw’s fuel and replace it with fresh fuel to clean the fuel system. Remove any dirt or debris from the fuel system’s components using a clean cloth.
3. Replace spark plug: Remove the old spark plug and put in the new one to replace it. Make sure the new spark plug’s gap is set properly, then screw it down firmly.

Chain Slipping Off

Possible Causes:

1. Worn sprocket nose. Over time, wear on the sprocket nose might make the chain loosen.
2. Dull or damaged chain. Chains are more prone to falling off the bar while cutting when they are dull or broken.
3. Loose bar nuts. The bar may slide and the chain may come off if the bar nuts are loose.

Step-by-step guide to fixing a chain slipping off:

1. Check sprocket nose: Remove the chain from the bar and look for any evidence of wear or damage before checking the sprocket nose. Replace it with a new one if it is worn.
2. Sharpen or replace chain: Use a round file to remove any worn-out or broken teeth before sharpening the chain. Replace the chain with a new one if it has sustained significant damage.
3. Tighten bar nuts: The bar nuts should be properly tightened by using a wrench. To avoid the bar becoming uneven, make sure they are tightened uniformly.

Chain Overheating

Possible Causes:

1. Dull or damaged chain. A dull or damaged chain can cause excessive friction, leading to overheating.
2. Chain tension too tight. If the chain tension is too tight, it can cause excessive friction and overheating.
3. Chain lubrication insufficient. If the chain is not properly lubricated, it can cause excessive friction and overheating.

Step-by-step guide to fixing a chain overheating:

1. Sharpen or replace the chain: If the chain is worn out or broken, sharpen it or get a new one.
2. Adjust chain tension: Loosen the bar nuts and adjust the chain tension in accordance with the manufacturer’s recommendations.
3. Lubricate the chain: Apply bar and chain oil to the chain’s moving components to lubricate it. To avoid over lubrication, be sure to distribute the oil properly.

Engine Overheating:

Possible Causes:

1. Dirty air filter. A dirty chainsaw air filter can restrict the airflow to the engine, causing it to overheat.
2. Fuel system clogged. A clogged fuel system can prevent the engine from getting the fuel it needs to run efficiently, leading to overheating.
3. Spark plug issue. A dirty or worn spark plug can cause the engine to run inefficiently and overheat.

Step-by-step guide to fixing an engine overheating:

1. Clean air filter: Remove the air filter from the chainsaw and wash it with soap and water to clean it. Before reinstalling it, let it thoroughly dry.
2. Clean fuel system: Drain the gasoline tank and chainsaw carburetor, then clean the lines and filter to clean the fuel system. Add fresh fuel to the tank afterwards.
3. Replace spark plug: Remove the old spark plug and replace it with a new one that complies with the manufacturer’s requirements to replace it.
