1. Leaf Blower Components

Understanding the basic components of a leaf blower will aid in diagnosing and repairing potential issues. Here is a list of the primary parts of a typical leaf blower:

• Engine/Motor: Provides the power to generate airflow.
• Fan: Creates airflow by spinning rapidly.
• Fuel Tank (for gas-powered models): Stores the fuel mixture.
• Battery (for battery-powered models): Powers the motor.
• Nozzle: Directs the airflow to move leaves.
• Throttle Trigger: Controls the speed of the airflow.
• Air Filter: Filters dust and debris from the air intake.
• Spark Plug (for gas-powered models): Ignites the air/fuel mixture in the combustion chamber.
• Carburetor (for gas-powered models): Mixes air with fuel.
• Control Handle: Provides grip and control.
• Exhaust: Releases gases from the engine.
