6. Maintenance

General Maintenance

• Cleaning: After each use, disconnect the battery and clean the tool with a damp cloth. Remove any debris, grass, or sawdust from vents and moving parts. Do not use harsh chemicals or abrasive cleaners.
• Storage: Store the tool, battery, and charger in a cool, dry, and well-ventilated area, away from direct sunlight and moisture. Keep out of reach of children.
• Inspection: Regularly inspect all fasteners, guards, and cutting attachments for wear or damage. Replace worn or damaged parts immediately.

String Trimmer Head Maintenance

• Line Replacement: Refer to the specific instructions for your trimmer head model for replacing the cutting line. Always use the recommended line diameter.
• Head Cleaning: Keep the trimmer head free of tangled grass and debris to ensure proper line feeding.

Pole Saw Chain Maintenance

• Chain Lubrication: Ensure the chain oil reservoir is filled with appropriate bar and chain oil before each use. The pole saw features an automatic oiler.
• Chain Tension: Check chain tension regularly. The chain should be snug but still able to be pulled freely around the bar by hand. Adjust as needed according to the pole saw's specific instructions.
• Chain Sharpening: A dull chain can cause poor cutting performance and increased kickback risk. Sharpen the chain regularly or replace it when necessary.

  • Ensure the battery is fully charged and securely inserted.
  • Check that the safety lock-out button is pressed before squeezing the trigger.
