Open the problem that matches yours. Everything inside comes from the troubleshooting chapter of the operator’s manual Husqvarna publishes for this model — a 60-page document we read on 10 September 2026.

Why we quote instead of rewriting. The manual is laid out as a table. Read by machine, a PDF loses the boundaries between columns, and pairing a symptom with the wrong remedy would give you a page that is confidently wrong rather than obviously broken. So we keep the maker’s order and words, and tell you how the table is built. The manual itself is linked further down.

We hold no photograph of the individual parts: Husqvarna does not publish them, and we would rather say so than show you the wrong picture. Prices are the maker’s United States list prices on the day we read them — an order of magnitude, not a quote. The buttons search shops in your own country, and those shops pay us a commission.

Where to buy

The search opens in your own country’s shop, in that shop’s language, with our tracking — the shop pays us a commission, you pay the same price.

WHERE THIS COMES FROM, AND WHAT WE ARE MISSING

Our sources

What is missing, said plainly. We hold no photograph of this exact machine, no repair times and no failure statistics — nobody publishes those honestly. Prices are Husqvarna’s United States list prices and will differ in your country. We are not a dealer: we do not stock parts, and the buttons search shops that pay us a commission.
