Husqvarna Chain Brake Reset Tools

These are the tools needed to reset the chainsaw chain brake:

  • Vise
  • Common end wrenches
  • Chainsaw bar wrench

Step 1: Reset the Chainsaw Chain Brake

  • Make sure you wear protective gloves while resetting the chain brake. Also, consult the owner’s manual for instructions.
  • Make sure to keep the chainsaw in one place using a vise for a smooth and safe chainsaw operation.
  • Check the oil level and remove any debris. Lubricate all moving parts of your machine regularly – this will help keep it running smoothly and prevent any damage or wear and tear from occurring over time.
  • Now it’s time to inspect the sprocket guard. Look around until you find a small gear mechanism. Now see whether the brake band is fixed or not.
  • Now Open the chain brake by pulling outwards on either side of it until it clicks into place; make sure that both sprocket and chain are correctly aligned when re-installing them again.
  • Lastly, carefully attach the sprocket guard and fix the screws.

Step 2: Adjust the Chain Tension 

A well-tightened chain increases equipment efficiency and minimizes the chances of possible hazards.

To adjust and modify the chain tension, make sure you follow the instructions below:

  • Check the chain tension and adjust as needed – this will ensure that the machine operates smoothly and efficiently.
  • Make sure the chain is well-tightened. Too loose or stretched chain can cause damage to the saw or sprocket, while too tight a chain will not allow the saw to spin freely.
  • Now it’s time to check if your brake is working correctly.
  • Find the adjustment screw of the chainsaw. It’s more likely to be on the left side of the bar. While in some models, it could be connected to the sprocket guard.
  • Check that both: links of the brake are rotating anticlockwise – this should stop the blade from moving forward or backward.
  • If it still does not work, then release the tension on both links of the brake by rotating each link anticlockwise a few times with your fingers – make sure you do this on both sides of the saw.
  • Next, re-tighten both links using the hex key – they should fit snugly and not move around once they are tightened.
  • Now start the chainsaw. Increase the tension if the chain is still moving. But if the bar is getting brushed against the brake, then decrease it.
  • The chain should not move when the chain brake is pushed forward. It is considered the perfect tension for a Husqvarna chainsaw.

Assembling a chain brake on a Husqvarna chainsaw requires prior knowledge and experience with the particular model. However, with the right tools and following instructions, you can perform the task safely and correctly.

  • To begin, make sure that the saw is unplugged or turned off. Then remove any bar and chain oil from the saw with a rag. Once the oil has been removed- locate and remove any screws or bolts attaching the clutch cover to the chainsaw. Next, use a flathead screwdriver to remove the clutch drum and sprocket assembly.
  • Once you have removed the pieces- you should be able to locate the chain brake assembly. There should be a small lever attached to the brake-applying band. This lever is what activates the chain brake when force is applied. Use a screwdriver and an Allen wrench to remove any screws attaching the lever and connecting it to the chain brake.
  • Finally, attach the brake-applying band to the clutch drum and refix the lever with the appropriate screws. Make sure everything is correctly aligned and secure before turning on the chainsaw. Testing the chain brake by hand is a great way to ensure that all steps were completed correctly.
