Complete Guide to Chainsaw Maintenance

Complete Guide to Chainsaw Maintenance

Having a well-maintained chainsaw is the best way to ensure it will cut smoothly and run efficiently, along with being safer to operate AND help to extend its lifespan. We’ll show you all the components you should inspect, clean, or replace to keep your equipment in top working condition.  

Inspect the Chain and the Bar 

These two parts are pretty important when it comes to cutting, so the chain and the bar are the first areas we’re going to look over to ensure that they’re in good working order. If the chain is not sharp, or your bar is damaged it may cause the chainsaw to work harder, which can shorten the lifespan. The chain should be able to move freely on the bar, and the teeth should not show signs of heavy rust or damage. If the chain displays any of these symptoms you should replace it, or it can be cleaned up and sharpened. Depending on how worn the chain is, it may just be easier to replace it.  

Chainsaw clutch cover

Next is to remove the cover over the clutch (depending on the model it may be two nuts holding the cover in place, or a released handle). Once the cover is removed, the bar and chain can be completely removed away from the saw. Remove the chain to get a closer look at the bar for any signs of wear or damage. Check the roller sprocket to make sure it turns freely. Look over any lubrication holes in the bar and make sure they’re clear and free of debris. The length of the bar can be cleaned with a hacksaw blade or small tool to remove any dirt and grime. The bar should be turned over periodically so that it wears evenly on both sides. If it is worn out or damaged, the bar should also be replaced.

Inspect the Recoil Starter 

The next area to inspect is the recoil starter. Remove the mounting screws and cover for the starter assembly and take a good look at the pull cord. If there is any wear or fraying it will need to be replaced. Inspect the hub for any damage or wear to the mechanisms and ensure that everything works as it should. Once again, if components are damaged or aren’t functioning properly, they should be replaced.

Inspect the Air Filter and Spark Plug

The air filter should be looked over for dirt and debris and can be washed with soapy water. If it’s beyond cleaning, it is easy to replace. Inspect the spark plug for signs of corrosion, and if found it will need to be replaced. Otherwise, it can be cleaned up and reinstalled. Also, inspect the wire cap to make sure that it’s not cracked or frayed.

Inspect the Throttle and Fuel Systems 

Next up is to check over the linkage to the cables and throttle to make sure everything is working properly, and there is no dirt or damage. Check to make sure that the shutoff switch works and is firm in its position. Also, ensure that the choke is working properly. The primer bulb should also be looked over for signs of cracking or leaking. When pressed, fuel should enter and fill up the bulb. If this doesn’t happen, you may want to inspect the fuel filter. Do this by removing the cap to the tank and then pull out the filter, looking for any signs of dirt or clogging. It can easily be replaced if necessary.

Inspect the Carburetor and Spark Arrestor 

The input for the carburetor should be inspected for any dirt or debris and can be flushed out with cleaner if needed. If there is little to no dirt, the carburetor shouldn’t have to be removed from the chainsaw. However, if it is extra grimy, remove the cover and throttle linkage, and the fuel lines will have to be disconnected so that the carburetor can be removed for a more thorough cleaning. Once that is finished, take a look at the spark arrestor for any heavy carbon buildup. This can be cleaned off with a wire brush. If this is something that is being cleaned regularly, it’s possible that too much oil is being used in your mix, resulting in excess carbon.

Inspect the Chain Brake 

The last area to inspect is the chain brake. In its normal operating position, the brakes should be pulled back and the chain should move freely. In the event of a kickback, the lever should lock forward and the chain will also lock. If the chain is able to move when in the locked position, you will have to have your chainsaw serviced by a professional.
