Resetting a Chain Brake on Husqvarna Chainsaws
If you’ve accidentally taken the clutch cover off your chainsaw with the chain brake still engaged, here is a step by step guide on how to reset the brake band.
Shown above you can see the inside of the brake band has come away from the outer edge of the drum. This is caused by the clutch cover being taken off while the chain brake is on. You will find you are not able to refit the clutch cover back on and it will need to be reset.
To reset the chain brake you will need a Wrench Chain Brake Reset Tool, the Husqvarna 236 model comes with the tool but the 135, 435, 445 and 450 models you can purchase the tool here. You will need to place this over the piece shown above and pull it until it clicks, it is quite stiff.
Once it is re-set you should see the metal brake band touching the casing again as shown below.
Once you have completed this, the casing can be placed back on and start the saw as normal, following the instructions on the sticker but without touching the throttle. Once it has started you can use the throttle.
We hope this helps you get back to sawing in no time.
