Official Hitachi gas leaf blower parts

Common replacement parts for Hitachi gas leaf blowers

• Air filter. The air filter is an absorbent foam rectangle that's mounted on the air intake to the carburetor. It filters the air that enters the carburetor before it mixes with the fuel.
• Fuel filter. The fuel filter attaches to the end of the fuel line inside the gas tank. It filters dirt and other particles from the fuel as gasoline moves from the fuel tank to the carburetor.
• Fuel line. A fuel line is a flexible tube that carries fuel from the tank to the carburetor and from the primer bulb to the fuel system.
• Primer bulb. The primer bulb removes air from the carburetor and fuel lines and fills them with fuel, so you can start the engine with fewer pulls on the starter rope. Activate the primer bulb by pressing it and allowing it to return to its original position.
• Recoil starter. The recoil starter is a starter system on top of the engine that consists of a rope and spring-loaded pulley system. Pulling the starter rope rotates the spring-loaded pulley and spins the crankshaft to start the engine.
• Fan assembly. The fan assembly is connected to the crankshaft of the engine. The engine crankshaft rotates the fan blades to produce the air flow through the blower.

How to fix excessive vibration problems on your Hitachi gas leaf blower

A damaged fan blade can cause a leaf blower to vibrate excessively; replace the fan blade if it’s cracked or damaged.

An engine problem can also make a leaf blower vibrate too much. Do preventive maintenance on the leaf blower to keep the engine running smoothly.

If the engine still runs rough after preventive maintenance, a dirty carburetor could be causing the engine to sputter and vibrate. A partially clogged jet in the carburetor may be preventing the right amount of fuel from reaching the engine cylinder. Rebuild or replace the carburetor if the engine sputters and vibrates.
