Precautions and Common Issues of Gas Blowers
Introduction
Gasoline powered blowers, also known as gas leaf blowers or gas blowers, are essential tools for maintaining clean and tidy outdoor spaces. However, like any machinery, they require proper handling and maintenance to function effectively. This article will guide you through the precautions to take when using a gasoline powered blower and how to troubleshoot common issues.

Cold Starting a Gasoline Powered Blower
1. Turn on the Ignition Switch: Set the choke lever to the "closed" position.
2. Throttle Control: Place the throttle control handle in the low position.
3. Prime the Carburetor: Press the primer bulb on the carburetor several times until fuel returns to the tank.
4. Start the Engine: Once the engine starts, gradually move the choke lever to the "open" position and let the engine run at low speed for 2-3 minutes before beginning your work.
Troubleshooting Common Gas Blower Issues
Difficulty Starting or Failure to Start
1. Check the Spark Plug:
- Remove any dirt or debris around the spark plug hole before removing the spark plug.
- Use a spark plug socket to remove it. Clean any carbon deposits and adjust the spark plug gap to 0.6-0.7mm.
- Test for a spark by holding the spark plug electrode near the engine metal parts and pulling the starter assembly. If there's no spark, replace the spark plug or repair the magneto.
2. Fuel System Check:
- Ensure there is fuel in the tank and that the fuel filter is not clogged. Clean or replace as necessary.
- Check for poor fuel quality and replace if needed. Ensure the fuel tank cap vent is not blocked.
3. Mechanical Checks:
- Inspect for worn piston rings or cylinders and replace if necessary.
- Adjust the carburetor to reduce fuel intake if the engine is flooded.
Reduced Power Output
1. Fuel Quality: Check for water in the fuel and replace it. Ensure the 2T oil (FC grade or above) is of good quality.
2. Carbon Build-up: Clean any carbon deposits in the exhaust or air filter. Replace the air filter if necessary.
3. Cylinder Maintenance: Remove carbon deposits from the combustion chamber.
Sudden Engine Shutdown
1. Piston and Cylinder Check: Inspect for seizure and repair or replace as needed.
2. Spark Plug Connection: Ensure the spark plug wire is securely connected and clean any carbon deposits.
3. Magneto Inspection: Replace if damaged.
Engine Overheating
1. Cooling System: Ensure the cylinder cooling fins are not blocked.
2. Lubrication: Adjust the gasoline and oil mixture ratio.
3. Air-Fuel Mixture:
- Adjust the carburetor.
- Check for air leaks at the flange sealing surface.
4. Combustion Chamber: Remove any carbon deposits.
Important Safety Precautions
1. Pre-Operation Checks: Always follow the manual's pre-operation warnings to prevent accidents and equipment damage.
2. Emergency Procedures: Know how to perform an emergency stop and operate all controls. Only trained personnel should operate the blower.
3. Flammable Materials: Keep flammable items like oil and matches away from the running engine.
4. Refueling Safety: Refuel in well-ventilated areas with the engine off. Gasoline is highly flammable and can explode under certain conditions.
5. Fuel Tank Precautions: Do not overfill the tank, and ensure the cap is tightly secured.
6. Spill Management: Clean any spilled fuel on the engine and allow it to evaporate before starting the engine.
7. No Smoking: Do not smoke or have open flames near the blower or fuel storage areas.
8. Exhaust Fumes: Gasoline blowers emit toxic carbon monoxide. Use ventilation equipment in enclosed spaces.
9. Muffler Safety: The muffler remains hot after the engine stops. Avoid contact to prevent burns and fire hazards. Allow the engine to cool before moving or storing indoors.
By following these guidelines, you can ensure the safe and efficient operation of your gasoline powered blower, keeping your outdoor spaces clean and well-maintained.
