Storage
For long-term storage of the String Trimmer:
1. Empty the fuel tank into a suitable fuel-storage container.
2. Pump the primer bulb on the carburetor until all fuel is discharged
through the clear fuel return hose.
3. Run the engine to remove any remaining fuel from the carburetor.
4. Perform all regular maintenance procedures and any needed repairs.
5. Remove the spark plug and squirt a very small amount of oil into the cylinder.
6. Pull the starter cord once. Use caution as oil may squirt out of the spark plug
opening while pulling the starter cord. Protect your eyes and keep your face away from the spark
plug opening.
7. Slowly pull the starter grip to bring the piston to the top of the cylinder.
8. Reinstall the spark plug.
9. Store the String Trimmer in a dry place away from excessive heat, sparks or open flame.
