    Question:
    I purchased a Husqvarna 435 chainsaw 2 or 3 years ago. I bought a new chain (Husqvarna brand) and installed it. It ran great for about 20 minutes then seized up. I had to remove the bar and chain, then re-install and it did it again. I have tried 3 different chains with the same results. When I re-install the original chain it runs great with no issues. What gives?

     Thomas,

    Thanks for contacting the Answer Army to post your questions.

    Assuming that the bar and chain match for the saw that you replaced, it may be the way that the saw is being used, or the wood that is being cut. If the wood is wet, it will cause the chips to stick to the bar and in the clutch and cause it to jam the saw up and won't turn the chain. But when you take it apart,  it unclogs it enough to use it again until it clogs again. If the wood is not wet, and you are making ripping cuts, that makes long chips and will clog it up also. If neither one of those is the case, you may not be getting enough oil to cool the bar and chain and the expansion caused by heat may stick the chain in the guide.

    If you don't feel that this is the problem I would make absolutely sure you are using the correct chain. If the pitch and gauge are incorrect it can cause the unit to seize.
