Step-by-Step Instruction

Step 1: Separate the spark plug cap from the chainsaw

Safety is always the top priority when working with a chainsaw. So before carrying out the maintenance routine, remove the spark plug cap first to prevent the chainsaw from suddenly operating.

Step 2: Vacuum the chain

Release the chain brake to slide the chain easier. Properly vacuum the chain by removing all the dust and dirt. Check the chain to find out all the links and teeth that are in poor condition and replace them promptly.

Step 3: Pick a suitable file for the task

The suitable file needs to fit almost wholly in the blade’s curve, and the file should be put above the blade at a 30-degree angle. Once the right file is decided, put the handle on it and arrange the file in the file guide.

Step 4: Put a sign on the starting place

The starting place is up to your liking, but make sure you use a marker pen to mark the first place being cleaned, so you can recognize when you’ve finished this step.

Step 5: Adjust the file in one line

Put the multifunction gauge on the chain and align it with the first link to be sharpened. Every blade needs filing with the same amount so that the flat edge on top of each cutter will be of the same length. This action will increase the speed of your cut and preserve the form of the chain.

Step 6: File the chain

If the guide is used together with a file then the job would be much easier, and this step even helps prevent burrs on the chain. Don’t forget to keep the file at the right angles to the bar, and use only forward stroke.

Step 7: Hone the sharpness of the other side of the chain

On the chain blades, the cutting edge works on both sides, so when finished on one side, turn the other side of the chainsaw and then sharpen the blades in the reversed angle.

Step 8: Sharpen the raker

Inspect each raker’s height, and make sure the tip of each is slightly lower than the top surface of the cutting blade. If rakers are placed too high, lower them down a little, and use a flat-file rather than the file used to sharpen the blades. 

Step 9: Recheck and finish off

After completing the sharpening task, keep going with the maintenance and checks. Unfasten the chain that was previously attached. Fill up the chain bar with oil and replace the spark plug cap.

Step 10: All set

Last but not least, dust off the chainsaw with a rag to remove any dirt. Replace the chain cover, and your chainsaw is all ready to go whenever you need it.
