Why won't my Makita Brush Cutter engine start?

  If your Makita Brush Cutter engine isn't starting, there are several potential causes. First, ensure you are pulling the starter rope strongly enough. Check if you have enough fuel and that the fuel filter isn't clogged. Also, examine the fuel tube for breaks and replace deteriorated fuel. If there's excessive fuel suction, adjust the throttle lever and try again. Make sure the plug cap is securely attached and the spark plug is clean and properly gapped. If these steps don't work, the carburetor, starter rope, or drive system may be abnormal, requiring professional inspection and maintenance.

Why does my Makita RBC411U engine stop soon after starting?

  igreenAug 6, 2025
  If your Makita Brush Cutter engine stops shortly after starting or the engine speed doesn't increase, it could be due to several reasons. Ensure you perform a proper warm-up operation. Check that the choke lever is set to “OPEN” after the engine warms up. A clogged fuel filter or a contaminated air cleaner can also cause these issues, so clean them. If these steps don't resolve the problem, the carburetor or drive system may be abnormal, requiring professional inspection and maintenance.

  If your Makita Brush Cutter's main unit is vibrating abnormally, stop the engine immediately. The cutter blade might be broken, bent, or worn, requiring replacement. Ensure the cutter blade-tightening nut is securely tightened. Also, check if the convex part of the cutter blade and cutter blade support fitting have shifted and attach them securely. If the problem persists, the drive system may be abnormal, requiring professional inspection and maintenance.

  If the cutter blade on your Makita Brush Cutter isn't rotating, stop the engine immediately. Check if the cutter blade-tightening nut is loose and tighten it securely. Also, inspect the cutter blade and dispersion-preventing cover for any caught twigs or foreign matter and remove them. If the issue persists, the drive system may be abnormal, requiring professional inspection and maintenance.

  If the cutter blade on your Makita Brush Cutter doesn't stop immediately after the engine is turned off, stop the engine immediately. This could be due to high idling rotation, which requires adjustment. Another cause might be a detached throttle wire, which needs to be securely attached. If the issue continues, the drive system may be abnormal, requiring professional inspection and maintenance.
