What to do if Makita Saw engine stops soon after starting?
- N
  Nicholas MosesAug 27, 2025
  If your Makita Saw engine stops soon after starting, or the engine speed doesn't increase, it might be due to insufficient warm-up; perform a warm-up operation. Also, ensure the choke lever is set to “ON” once the engine is warmed up. A clogged fuel filter or a contaminated air cleaner can also cause these issues; clean them. For abnormal carburetor or drive system make request for inspection and maintenance.

  If the cutting disc on your Makita Saw isn't rotating, stop the engine immediately. This could be due to a loosened cutting disc-tightening bolt; ensure it is tightened securely. If the bolt is secure and the disc still doesn't rotate, the drive system may be abnormal, requiring professional inspection and maintenance.

  If the cutting disc on your Makita Saw doesn't stop immediately, stop the engine immediately. This may be due to high idling rotation, which requires adjustment. If that's not the case, it could be due to a detached throttle linkage or an abnormal drive system, both of which require professional inspection and maintenance.

  If your Makita Saw engine stops soon after starting, it could be due to insufficient warm-up (perform warm-up operation). Another reason might be that the choke lever is set to the wrong position (set to “ON ”). A clogged fuel filter (clean it) or a contaminated air cleaner (clean it) could also be the cause. For abnormal carburetor or drive system it is recommended to make request for inspection and maintenance.

  If your Makita Saw engine stops shortly after starting, or the engine speed doesn't increase, it might be due to several reasons. Ensure you perform a warm-up operation. Check that the choke lever is set to “ON ” if the engine is warmed 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.
