When working with wood, having a sharp chainsaw is a must. A sharp chainsaw will surely save us some effort during the work and will make the equipment safer to use. Besides, sharp chainsaw will guarantee a straight cut too. That’s why, don’t postpone sharpening your chainsaw before working. Find how to do it below:
#1 Decide the gauge or the size of the saw’s chain
In doing the job, you will need a chainsaw file or a rotary grindstone that fits the chain tooth of your saw. So, you need to determine the size of the teeth because there a couple of sizes: 7/32, 5/32, and 3/16 of an inch in diameter.
#2 Clean the Chain
Using degreasing detergent or mineral spirit, thoroughly clean the chain from any dirt, debris, or oil. When cleaning it, make sure you don’t put too much solution on the components.
#3 Find Out Any Overly Worn or Damaged Teeth and Links
Do the inspection and discard any weakened, damaged, broken, chipped, bent, and or overly worn teeth and chains as they can be dangerous for you when the saw is in motion.
#4 Stabilize Your Saw in a Right Position
Place your saw on a solid surface and make sure the saw is stable and the blade is firm to provide an accurate and safe filing.
#5 Use the Leading Cutter as the Starting Point
But if all the cutters come with the same length, you can use any cutter as the starting point. Only make sure that each cutter is filed and the flat edge of every cutter is in the same length.
#6 Adjust the File in the Notch on the Cutter’s Front Part
The file’s curve should perfectly fir the cutting tip’s face curve and the 20% of the top of the file diameter should be above the tooth’s top part.
#7 Match the Angles of the Chain
Make sure how you hold the file and how you ground the cutter are at the same angle. Check for any visual aid provided as witness markers on the saw teeth.
#8 Push the File at the Best Direction
Do this step by sliding the file across the cutter’s face. Use a twisting motion in moderate mode to discharge the removed filings or metal chips.
#9 Work with the Tooth Slowly but Carefully
By starting from the beginning point at the loop, work the second tooth and continue making progress through the saw’s chain.
#10 Work with the Other Sides of the Saw
Continue working with the other sides of the saw. Continue sharpening the saw around the unfiled saw’s teeth that are angled in the other directions.
#11 Clear the Cutting Edges
Make sure you don’t forget to clear the depth gauge or the rakers. They are the hook in curve shape and are located between the cutters.
#12 File Any Depth Gauge or Raker
File those elements so that they won’t interfere the cutter with a flat mill bastard file.
#13 Give some Oil
Finally, oil the saw’s chain by soaking or saturating them. Also, check the saw’s tension before using it to cut again.
