Safety Precautions and Warnings

Operating the Husqvarna 125B leaf blower requires strict adherence to safety precautions to prevent injury and ensure safe usage. Before operating, thoroughly read the operator’s manual and understand all safety warnings. Always wear appropriate personal protective equipment (PPE), including eye protection (safety glasses or goggles), hearing protection (earplugs or earmuffs), and a dust mask, to avoid potential hazards.

Never operate the blower in enclosed spaces, as exhaust fumes contain carbon monoxide, a colorless and odorless gas that can be fatal. Keep children and pets away from the work area to prevent accidental injury. Inspect the blower before each use, ensuring all parts are in good working condition and properly secured. Do not use the blower if it is damaged or malfunctioning. When refueling, always turn off the engine and allow it to cool completely. Refuel in a well-ventilated area and avoid spilling fuel.

Be aware of your surroundings and avoid blowing debris towards people, animals, or property. Maintain a firm grip on the blower and use it only for its intended purpose. Store the blower in a safe location, out of reach of children, and away from flammable materials. Following these precautions will contribute to safe and responsible operation.

Assembly Instructions

Proper assembly of the Husqvarna 125B leaf blower is crucial for its safe and efficient operation. Before beginning, unpack all components and verify that all listed parts are present. Consult the parts diagram in your operator’s manual for a detailed illustration of each component. The primary assembly involves attaching the blower tubes. Align the blower tubes with the blower housing outlet and firmly push them together until they click into place. Ensure the tubes are securely connected to prevent them from detaching during operation.

Some models may require the attachment of a nozzle to the end of the blower tube for concentrated airflow. Refer to the manual for the specific nozzle attachment procedure. If your model includes a vacuum kit, follow the separate instructions provided for its assembly and attachment. This typically involves replacing the blower tubes with the vacuum tubes and attaching a collection bag.

Double-check all connections to ensure they are secure before adding fuel and attempting to start the blower. If you encounter any difficulties during assembly, consult the operator’s manual for troubleshooting tips or contact Husqvarna customer support for assistance. Incorrect assembly can lead to performance issues or safety hazards, so it is essential to follow the instructions carefully.

Operating Instructions

Once assembled, understanding the operating procedures for your Husqvarna 125B is key to efficient and safe use. Before starting, ensure the blower is on a stable surface and away from flammable materials. Refer to the fuel and oil requirements section of this guide to properly mix and add fuel to the tank. Prime the carburetor by pressing the primer bulb several times until fuel is visible.

Engage the choke lever to the “full” position for a cold start. Grasp the starter handle firmly and pull it sharply several times until the engine sputters. Gradually move the choke lever to the “half” position and continue pulling the starter until the engine starts and runs smoothly. Allow the engine to warm up for a few minutes before disengaging the choke completely.

To operate, hold the blower firmly with both hands, directing the nozzle towards the debris you wish to move. Vary the throttle speed as needed to adjust the blowing force. When finished, release the throttle and allow the engine to idle for a short period before switching it off using the stop switch. Always store the blower in a cool, dry place with the fuel tank empty to prevent fuel-related issues.

Carburetor Adjustment

Proper carburetor adjustment is crucial for the Husqvarna 125B to run efficiently and effectively. A poorly adjusted carburetor can lead to starting problems, poor performance, and increased fuel consumption. Generally, the carburetor has three adjustment screws: the high-speed (H), low-speed (L), and idle speed (T) screws. It is recommended to perform any adjustments after the engine is warmed up.

Before making any adjustments, ensure that the air filter is clean and the spark plug is in good condition. Start by adjusting the low-speed screw (L) to achieve a smooth idle without stalling. Then, adjust the high-speed screw (H) for optimal performance at full throttle. Be cautious not to lean out the mixture too much, as this can damage the engine.

Finally, use the idle speed screw (T) to set the desired idle speed. If you are unsure about adjusting the carburetor, consult a qualified service technician. Incorrect adjustments can cause serious engine damage. Always refer to the manufacturer’s specifications for the correct settings. Remember to make small adjustments and test the blower’s performance after each change.

Fuel and Oil Requirements

Using the correct fuel and oil mixture is essential for the proper operation and longevity of your Husqvarna 125B leaf blower. This blower requires a mixture of gasoline and two-stroke oil. Always use fresh, high-quality gasoline with an octane rating of 89 or higher. Ethanol content should not exceed 10% (E10) to prevent damage to the fuel system components.

For the two-stroke oil, Husqvarna recommends using their own brand of two-stroke oil, which is specifically formulated for their engines. If Husqvarna oil is not available, you can use a high-quality, air-cooled two-stroke oil that meets or exceeds JASO FD or ISO EGD standards. The correct mixing ratio is typically 50:1 (50 parts gasoline to 1 part oil).

To mix the fuel, pour the correct amount of two-stroke oil into a clean fuel can, then add the gasoline. Close the can tightly and shake vigorously to ensure the oil and gasoline are thoroughly mixed. Always mix the fuel in a separate container and never directly in the fuel tank of the blower. Use the fuel mixture within 30 days to avoid issues caused by stale fuel.

Maintenance Schedule

Regular maintenance is crucial for ensuring the reliable performance and extending the lifespan of your Husqvarna 125B leaf blower. Following a consistent maintenance schedule will help prevent costly repairs and keep your blower running smoothly. Before performing any maintenance, always ensure the engine is off and the spark plug wire is disconnected.

Daily/Before Each Use: Inspect the air filter and clean if necessary. Check the fuel level and ensure the fuel cap is tight. Inspect the blower tubes for any damage or obstructions.

Weekly: Clean the exterior of the blower. Inspect the spark plug and clean or replace if needed. Check the cooling fins on the engine for debris and clean as necessary to prevent overheating.

Monthly: Clean or replace the air filter. Inspect the fuel filter and replace if necessary. Check the starter cord and recoil mechanism for proper operation. Sharpen or replace the blower fan if it is damaged.

Annually: Have the carburetor inspected and cleaned or adjusted by a qualified service technician. Replace the fuel lines and fuel filter. Inspect the muffler and spark arrestor screen and clean or replace if necessary. Store the blower properly during the off-season, draining the fuel tank and carburetor.

Troubleshooting Common Issues

Even with regular maintenance, you may encounter some common issues with your Husqvarna 125B leaf blower. Here’s a guide to help you troubleshoot and resolve some of the most frequent problems:

Blower Won’t Start: First, ensure the fuel tank has fresh fuel mixed at the correct ratio. Check the spark plug for fouling or damage, and replace if necessary. A clogged air filter can also prevent starting, so clean or replace it. If these steps don’t work, the carburetor may need adjustment or cleaning.

Blower Starts but Runs Poorly: This could be due to a dirty air filter, a faulty spark plug, or stale fuel. Try cleaning the air filter, replacing the spark plug, and using fresh fuel. If the problem persists, the carburetor might need adjustment.

Blower Lacks Power: Check for obstructions in the blower tubes or the engine’s cooling fins. A worn piston ring or cylinder can also cause a loss of power, requiring professional repair. Ensure the spark arrestor is clean, as a clogged one can restrict exhaust flow.

Blower Smokes Excessively: This is often caused by an incorrect fuel mixture (too much oil). Empty the fuel tank and refill with the correct mixture. A worn piston ring or cylinder can also cause excessive smoking.
