Maintenance
1. Cleaning
After each use, ensure the tool is disconnected from the battery. Clean the cutting attachments (trimmer head, edger blade) of any grass clippings, dirt, or debris. Use a damp cloth to wipe down the Power Head and shafts. Do not use harsh chemicals or abrasive materials.
2. String Trimmer Line Replacement
Utilize the POWERLOAD technology for easy line replacement. If the line is depleted, feed new line through the designated holes in the trimmer head and activate the POWERLOAD function as described in the operating instructions.
3. Edger Blade Inspection
Regularly inspect the 8-inch edger blade for wear or damage. Replace the blade if it becomes dull, bent, or cracked to maintain optimal performance and safety. Refer to the EGO Power+ website or authorized service centers for replacement blades.
4. Battery Care
Store the battery in a cool, dry place away from direct sunlight and extreme temperatures. Do not store the battery in a discharged state for extended periods. Always use the EGO Power+ charger for recharging.
Troubleshooting
If the tool fails to operate, ensure the battery is fully charged and properly installed. Check that the attachment is securely connected to the Power Head. If issues persist, consult the full EGO Power+ user manual or contact customer support.
