Why do my grass trimmer and brushcutter start and then die?

While working with your Husqvarna petrol-powered grass trimmer or brushcutter, it can shut off unexpectedly. This could mean there is an issue with the product.

The first thing to check is if there is fuel in your product. Make sure that the grass trimmer or brushcutter is filled with fuel before starting it.

The next thing that can affect your grass trimmer and brushcutter is old fuel.
When storing your grass trimmer or brushcutter with fuel in them, fuel can become stale. This will result in the system becoming clogged or restricted.

Fuel-related failures are not covered under warranty. The product would need to be serviced by a local authorised service centre.
Before storing your grass trimmer or brushcutter, make sure that there is no fuel in it to prevent this type of issue. Always use fresh fuel when starting your product.

If you still experience your grass trimmer or brushcutter starting and then dying, check the air filter. Clean or replace the air filter if it is dirty or damaged.

Another reason that your grass trimmer or brushcutter might start and then die may be that the spark arrestor is dirty or clogged. If this is the case, clean it with a wire brush.

If your petrol-powered grass trimmer and brushcutter die when turned sideways, it is usually because the fuel filter is held away from the fuel, as the position of the product changes. The fuel filter must be able to stay in the fuel as the position of the chainsaw is changed.

Husqvarna grass trimmer and brushcutter are equipped with fuel lines of specified lengths and flexibility along with weighted fuel filters. This allows the filter to “follow” the fuel and remain submerged. It is important to always use the correct fuel line and fuel filter for your specific product. You can find this information in the operator’s manual.

Your grass trimmer and brushcutter may also die when turned sideways due to leakage or because the fuel lines need to be reset. In this case, please contact your local authorised dealer.
