Air filters
There are two types of air filters in power equipment: foam filters and pleated media filters. Often, after 100 hours of use, foam filters become stiff and yellowed. They need to be changed. For pleated media filters, on average, replace them after 50 hours of use. However, if an air filter is torn, remove it immediately and change it.
Cleaning or blowing out an air filter to remove contaminants can reduce its efficiency or even damage it. As a central part of your machine's engine system, it should be replaced regularly.
⚠️In a dusty environment, more frequent maintenance is recommended to protect the mechanics of your machine.
