To start the Poulan Pro PP428C Trimmer, ensure it is on a flat surface. Switch the choke to the full position, press the primer bulb 6 times, and pull the starter cord until the engine starts. Once started, move the choke to the run position.
The correct fuel mixture for the Poulan Pro PP428C Trimmer is 40:1, which means 3.2 ounces of 2-cycle oil per gallon of gasoline. Use fresh, unleaded gasoline with a minimum 87 octane rating.
To replace the trimmer line, turn the trimmer off and disconnect the spark plug wire. Remove the spool from the trimmer head, wind new line onto the spool, and reattach the spool to the trimmer head.
If the trimmer won't start, check the fuel level and mixture, inspect the spark plug for wear or damage, and ensure the air filter is clean. Also, verify that the choke is in the correct position and the primer bulb is functioning properly.
The air filter should be checked before each use and cleaned or replaced if it is dirty. Typically, replace the filter every 25 hours of operation or once a season for optimal performance.
To store the trimmer for the winter, empty the fuel tank, clean the exterior, and inspect for any damaged parts. Store in a dry, cool place, and consider adding a fuel stabilizer if fuel remains in the tank.
Regular maintenance includes checking and cleaning the air filter, inspecting and replacing the spark plug annually, checking the fuel system for leaks, and ensuring the cutting attachment is sharp and balanced.
If the trimmer line is not feeding properly, ensure the spool is correctly installed and the line is wound tightly and evenly. Check for obstructions or tangles and ensure the line is the correct diameter for the trimmer.
Always wear appropriate personal protective equipment, such as gloves, eye protection, and long pants. Ensure bystanders are at a safe distance, and never operate the trimmer in wet conditions to avoid electric shock.
Excessive vibration may be caused by an unbalanced or damaged cutting attachment. Inspect the attachment for damage, ensure it is properly secured, and replace it if necessary. Check the engine mounts for wear or damage.
