1. Prepare the Equipment: Ensure your trimmer, leaf blower, or chainsaw is turned off, the engine is cool, and the spark plug wire is disconnected.

Operating the Primer Bulb

The primer bulb's function is to draw fuel from the tank into the carburetor, expelling air and preparing the engine for starting. This process is known as priming.

1. Fill Fuel Tank: Ensure your equipment's fuel tank contains the appropriate fuel mixture.
2. Press the Primer Bulb: Repeatedly press the primer bulb with your thumb. You should observe fuel flowing through the clear fuel lines and into the carburetor.
3. Observe Fuel Flow: Continue pressing until you see fuel in the bulb and any air bubbles are expelled. Typically, 5-10 presses are sufficient, but refer to your equipment's primary manual for specific recommendations.
4. Start Engine: Once primed, follow your equipment's standard starting procedure.

Efficiently priming your equipment with this bulb pump ensures quick and reliable starts for your trimmer, leaf blower, or chainsaw.

Maintenance

Regular inspection of your primer bulb can help prevent starting issues.

• Visual Inspection: Periodically check the primer bulb for any signs of cracking, hardening, or discoloration. A damaged bulb will not prime effectively.
• Check for Leaks: Ensure all fuel line connections to the primer bulb are secure and free of leaks.
• Replacement: If the primer bulb shows signs of wear, damage, or fails to prime the engine, replace it promptly with a compatible part.
