Accurately Determine the Status of a Clogged Vent
- Conduct a preliminary assessment based on abnormal operating conditions
- Common signs include fuel overflowing easily during refueling, noticeable negative pressure sound in the tank, or irregular vibrations during operation
- Locate the vent, usually at the top of the fuel tank or near the fuel filler port
- Carefully inspect the vent for dust, oil, or foreign matter
- Determine the approximate extent of the blockage and avoid any unintended operation
Prepare for Safety Before Cleaning
- Keep the fuel level in the tank low to reduce the risk of spillage
- Move the equipment to a well-ventilated area free of fire and heat sources
- Operators should wear anti-static clothing and non-slip gloves
- Prepare appropriate tools: soft nylon brush, specialized airway cleaner, compressed air pump, and clean cloth
Avoid using hard tools to prevent damaging the vent structure
Gently Clear the Vent Hole
- For minor blockages: wipe the outside with a dust-free cloth, then gently insert a soft nylon brush
- Maintain even pressure and avoid puncturing the inner wall
- For severe blockages: drip a small amount of specialized airway cleaner to soften deposits
- Use a compressed air pump with adjusted pressure to slowly blow air into the vent
Ensure that the airflow is smooth and does not impact the hole structure
Post-Clearing Inspection and Daily Maintenance
- Verify effectiveness by blowing air into the vent or observing oil flow during refueling
- Inspect the vent's protective structures and replace any damaged ones immediately
- Regularly wipe the outside of the vents with a dust-free cloth
- Increase inspection frequency after using equipment in dusty or oily environments
