  • First, go through all the specifications of your chainsaw blade. These specifications especially include the pitch and gauge of a chainsaw chain. 
  • They’re significant to know because they affect the chainsaw blade you can use. Luckily, you can find the specifications on the chainsaw’s box. 
  • The manufacturer generally provides a manual with instructions to help you understand the specifications.

Step:2- Positioning the chainsaw

  • Place your sharpener on the ground in a flat position. It’ll prevent shaking during the operation and ensure preciseness of work.

Step:3- Installing the sharpening stone

  • You should already know the pitch and gauge of your chainsaw chain. It’s mandatory to install your sharpening stone with the right width. Otherwise, it won’t fit in the gap between the chainsaw blade’s teeth.
  • The width of a sharpening stone usually is 3/16 inches. All sharpening stones aren’t suitable for your chainsaw. Make sure which one suits the chain best. 

Step:4- Adjusting the angle and depth

  • Put the blade in the chainsaw sharpener’s holder first. Then, focus on adjusting the angle. 
  • The angle should be between 0 degrees and 60 degrees. It can go to 80 degrees in some special cases. 
  • It’s time to remember the blade tooth angle. Loosen the knob on the blade’s holder to adjust the tooth angle.
  • At the same time, you need to adjust the depth. Improper depth adjustment damages the blade teeth, resulting in a damaged blade. So, find a proper depth to prevent the too deep or too shallow cut.

Step:5- The final work: sharpening

  • Start by lowering the grinder wheel on the blade’s first tooth. When you can establish contact, some sparks can be observed.
  • After a while, lift the grinder to check that the tooth’s inner surface has a shiny finish.
  • If you find everything okay, then you have sharpened your first tooth. Your responsibility is to repeat this process around 60 more times.
  • Never put a rush while sharpening the tooth on one side of the blade. Once a set of teeth is sharpened, readjusting the grinder is mandatory then. Put the angle back in the opposite direction with the same amplitude.
