Poulan Pro WT3100 Operator's Manual

To start the Poulan Pro WT3100 Trimmer, set the choke lever to the full choke position. Prime the engine by pressing the primer bulb six times. Pull the starter rope until the engine fires. Move the choke to the half choke position and pull the starter rope again until the engine starts.
Use a fresh, unleaded gasoline mixed with a high-quality 2-cycle engine oil at a 40:1 ratio.
If your trimmer won't start, check the fuel level and ensure it's fresh. Inspect the spark plug for damage or fouling, and clean or replace it if necessary. Also, ensure the air filter is clean and not clogged.
Replace the trimmer line whenever it becomes brittle, breaks frequently, or the spool is empty. Regularly inspect the line to ensure optimal performance.
Regular maintenance includes checking and cleaning the air filter, inspecting and replacing the spark plug annually, and ensuring the trimmer head is free from debris.
To clean the air filter, remove the air filter cover and take out the filter. Wash it with warm, soapy water, rinse thoroughly, and allow it to dry completely before reinstalling.
Excessive vibration may indicate that the trimmer head is unbalanced or damaged. Inspect the trimmer head for damage and ensure it's properly assembled. Replace any damaged parts.
To extend the life of your trimmer, perform regular maintenance, use the correct fuel mix, avoid overloading the engine, and store the trimmer in a dry, protected area.
If the line isn't advancing, check for tangles in the spool, ensure the line is wound correctly, and verify that the trimmer head is clean and free from debris.
To replace the spark plug, disconnect the spark plug boot, use a spark plug wrench to remove the old plug, and install a new one with the correct gap setting. Reattach the spark plug boot securely.
