How to clean or replace the air filter on your grass trimmer and brushcutter
For your grass trimmer and brushcutter to function optimally, the air filter needs to be clean and working properly.
If the air filter is dirty or damaged, there may be issues with starting the products or you may experience loss of power while using them.
Air filter types:
- Foam filter
- Nylon filter
- Paper filter
- Felt filter
The air filter must be regularly cleaned to remove dust in order to avoid:
- Problems starting up
- Loss of engine power
- Unnecessary wear to engine parts
- Excessive fuel consumption
Do maintenance on the air filter more frequently in dusty conditions.
Cleaning the air filter
- Remove the air filter cover and take out the air filter.
- Clean the filter with a soft brush.
- Put the clean air filter back and replace the cover.

- Remove the air filter cover and take out the air filter.

Oiling the air filter
If you are using your product in dusty conditions, the air filter must be soaked in oil.
This applies to foam filters only.
Always use Husqvarna air filter oil or air filter spray.
WARNING: Use protective gloves, since the air filter oil can cause skin irritation.
- Put the air filter in the plastic bag and pour the filter oil over it.
- Knead the plastic bag to distribute the oil.
- Squeeze the excess oil out of the filter inside the plastic bag and pour off the excess before fitting the filter to your trimmer.
Replacing the air filter
If the air filter has been in use for a long time, it cannot be cleaned completely.
In this case, replace the air filter with a new one. Do this at regular intervals.
Depending on the model of your grass trimmer or brushcutter, the air filter may differ.
