Products Application
Routine Air Filter Replacement
Regular cleaning and replacement of the air filter is essential for preventing carburettor malfunctions, maintaining engine power, and avoiding excessive fuel consumption . A clogged filter restricts airflow, causing the saw to run lean and potentially leading to engine damage. Replacement every 25-50 hours or when visibly dirty is recommended for professional saws.
Full Service Kit Maintenance
Service kits combine the air filter with fuel filter and spark plug, making routine servicing efficient and ensuring all standard maintenance components are renewed simultaneously . This is recommended for high-hour professional saws used in demanding forestry and arborist work.
Filter Upgrade Options
The Husqvarna 365 can be equipped with different types of air filters according to working conditions, weather, or season. The nylon version (503818005) may be specified for particularly dusty conditions, while the flocked/felt standard filter suits general use. Contact your dealer for specific application advice .
