How to Tighten Chain on Stihl Chainsaw

To tighten the chain on a Stihl chainsaw, you must loosen the bar nuts and adjust the tensioning screw. Start by loosening both of the bar nuts with a wrench while holding onto the clutch cover. Then, turn the tensioning screw clockwise until it stops.

Place your thumb over the chain drive link and pull up firmly on it; if there is more than 1 inch of chain slack then you need to continue tightening it further. Finally, retighten both bar nuts so that they are snug but not overly tight before testing out your saw again.

  • Preparing the Saw: Before attempting to tighten the chain on a Stihl chainsaw, make sure that it is turned off and unplugged.
  • If you have been using it recently, wait until it cools down before continuing with this process
  • Removing Chain Cover: Start by removing the chain cover from your Stihl chainsaw so that you can access the bar and saw chain inside of it.
  • This should be done carefully, as pulling too hard can result in damage to both components or other parts of your saw.
  • Locate Adjustment Screws: Once the cover has been removed, locate two adjustment screws on either side of your saw near where the bar connects to its body.
  • These screws control how tight or loose your saw’s chain is when running – one for tightening and one for loosening respectively.
  • Turning Adjustment Screws: To begin tightening your Stihl chainsaw’s chain, turn only one screw clockwise with an appropriate-sized screwdriver or wrench until it stops moving further into its housing (do not over-tighten).
  • Doing this will help ensure there isn’t any slack in your saw’s drive system when operating at full speed later on down the line – preventing potential damage due to wear and tear over time!
  • Replacing Chain Cover: After turning both adjustment screws appropriately (one clockwise and one counterclockwise), replace the cover onto your Stihl chainsaw securely before testing out its new tightness level while running at idle speeds first before increasing power levels afterward if needed.

To properly tighten a Stihl blade, you must first locate the two screws on either side of the blade. Once located, use an appropriate-sized screwdriver to loosen both screws and then slide the blade onto the spindle until it is snug against the washer or retaining ring. Now re-tighten the two screws that were loosened earlier in opposite directions with equal force.

Be sure not to over-tighten them as this could cause damage to your saw blade or even risk injury due to a broken saw blade flying off at high speeds. The last step is to adjust the tension by using a simple wrench if needed and ensure that your new installation is tight enough for proper operation but not so tight that it causes excessive wear on other components of your saw.
