Petrol chainsaw. Spare parts with Husqvarna’s own order codes, and the troubleshooting chapter of the operator’s manual.
No longer built — parts still listed Photograph: a chainsaw. We hold no photograph of this exact machine, and we would rather say so than pass one off.

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.
Parts & prices
Every code below is Husqvarna’s own, read from the maker’s parts pages for this exact model. The code is printed on the part itself — on a label, moulded into the plastic or stamped in the metal. Read it off the broken part and type it here to find it straight away.
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.
Tools you’ll need
Chosen for this family, not a generic list. Prices and availability come from the shop in your country, with our tracking.
Specifications
Copied field for field from the manufacturer’s own product page on 10 September 2026, in the maker’s units. We do not convert them: a rounded conversion is how a torque figure quietly becomes wrong.
Manuals & documents
We link the maker’s documents instead of re-hosting them, so you always open the version Husqvarna is publishing today.

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.
