Why the Air Filter Cover Matters

The air filter helps prevent airborne contaminants from entering the engine. The 523013101 cover provides the outer protective enclosure for this filter on compatible hedge trimmers.

A missing or damaged cover can leave the filter more exposed to:

• Grass clippings
• Dust
• Dirt
• Leaves
• Outdoor debris
• Physical impact
• Excessive contamination

Maintaining the complete factory air-filter assembly helps keep the filter correctly positioned and protected during normal equipment operation.
