A Ryobi weed eater requires regular cleaning and maintenance. During these tasks, the operator should look for loose or broken parts that need replacing. If broken or loose parts are found, replace or fix them immediately, as a small problem can grown into a large, expensive problem. If you feel unqualified to make any repairs, let a professional Ryobi service mechanic make them for you. Improper or poorly done repairs can also exacerbate engine problems.
Things You'll Need
- Socket wrench
- Electrical tape
- Mild detergent
- Other tools (as necessary)
Move the ignition switch into the “Off” setting. Set the Ryobi weed eater on a flat, well-lit workbench or similar area. Get all of the tools and cleaning implements ready before beginning repairs, so they can be easily accessed at all times.
Unhook the spark plug’s black rubber boot, usually located on the underside of the power head on most Ryobi trimmers, with your fingers. Wiggle the boot lightly back and forth if it’s stuck. Use the flat end of the screwdriver for leverage if necessary.
Set the socket wrench onto the spark plug and unscrew the plug, removing it from the cylinder. Tape the rubber boot and wire so that their metal prongs are touching a metal point on the engine block. This will prevent any accidental starts and ground the ignition system, preventing electrocution.
Clean the entire Ryobi weed eater with a rag and brush before making any repairs. Use a mild detergent, like dish soap, to scrub any tough areas on the engine block, shaft or mowing head. A clean trimmer will allow you to spot any other, hidden damage.
Close the choke lever, moving it into the “Stop” setting. Unscrew the air filter and muffler cover from the back of the engine. Pull the air filter out and clean the area around the carburetor.
Proceed to disassemble the related engine parts, allowing you access to the part or parts that need repairing. Remove the broken parts as necessary. Install the new parts as needed and reassemble the trimmer in reverse order.
