      If the nylon cutting cord isn't being cut to the correct length on your Makita Trimmer, one potential reason is that the cord extends past the protector, in such case rewind the cord. Another potential reason is that the cord cutter on the protector is damaged or missing, and in this case you should contact an authorized service center for repairs.

      Robert Martinez MDAug 20, 2025
      Abnormal vibration in your Makita Trimmer can stem from several issues. Check for these potential causes: * A broken, bent, or worn cutting tool. If so, replace it. * A loose cutting tool, which you should tighten securely. * An unbalanced nylon cutting head due to a broken nylon cutting cord. Try feeding the cord by tapping the cutting head on the ground. * An irregular attachment of the cutting tool. Ensure it's properly attached. * An abnormal drive system. In this case, it's best to contact an authorized service center for repairs.

    Why is my Makita Lawn and Garden Equipment vibrating abnormally?
    • V
      villapatrickAug 27, 2025
      If your Makita Lawn and Garden Equipment vibrates abnormally, several issues could be the cause. The cutting tool might be broken, bent, or worn, requiring a replacement. Alternatively, the cutting tool may be loosely attached and need tightening. If you're using a nylon cutting cord, one end may have broken, unbalancing the cutting head; try feeding the cord by tapping the head on the ground. Also, check for irregular attachment of the cutting tool and ensure it's properly attached. If none of these resolves the vibration, there may be an abnormal drive system, in which case contact an authorized service center for repairs.

    • A
      alexpierceAug 31, 2025
      If the cutting tool on your Makita Lawn and Garden Equipment isn't rotating, it could be due to a few reasons. First, check if the cutting tool is loosely attached and tighten it securely. It's also possible that the cutting tool has caught a twig or other foreign matter, so remove any obstructions. If neither of these solutions works, the drive system may be abnormal, and you should contact an authorized service center for repairs.
