Cleaning the Air Filter
If dirt is allowed to collect in the air filter, the airflow will be reduced, leading to reduced performance, and increased
operation noise. Be sure to clean the filters regularly.
How to Cleaning
Use a vacuum cleaner to remove dust and dirt from the air filter, or wash in a synthetic detergent. After washing, dry in a
shaded place, then reinstall.
