    Why Dolmar MS-245.4 U Brush Cutter engine does not start?
    • M
      Misty ThomasAug 1, 2025
      Several factors can prevent your Dolmar Brush Cutter's engine from starting. It could be due to failure to operate the primer pump, so push it 7 to 10 times. Other reasons include low pulling speed of the starter rope (pull strongly), lack of fuel (feed fuel), a clogged fuel filter (clean it), a broken or deteriorated fuel tube (straighten or replace it), or deteriorated fuel (replace with new one, recommended every month). Also check for excessive suction of fuel, detached plug cap (attach securely), contaminated spark plug (clean it), abnormal clearance or other issues with the spark plug (adjust clearance or replace it). If none of these resolve the issue, the carburetor or drive system may be abnormal, requiring professional inspection and maintenance.

    What to do if Dolmar Brush Cutter engine stops soon after starting?

      Mary MillerAug 6, 2025
      If your Dolmar Brush Cutter engine stops shortly after starting, it might not be sufficiently warmed up, so perform the warm-up operation. Another cause could be the choke lever being set to “CLOSE” when the engine is warm; set it to “OPEN”. Also, check for a clogged fuel filter (clean it) or a contaminated or clogged air cleaner (clean it). If the problem persists, the carburetor or drive system may be abnormal, requiring professional inspection and maintenance.

      If the cutter blade on your Dolmar Brush Cutter doesn't stop immediately, the high idling rotation may be the issue, so adjust it. Also, check if the throttle wire is detached and attach it securely. If these steps don't solve the problem, the drive system may be abnormal, requiring professional inspection and maintenance.

    How to fix abnormal vibration of Dolmar MS-245.4 U Brush Cutter?
    • M
      Miss Michelle Murray MDAug 16, 2025
      Abnormal vibration in your Dolmar Brush Cutter can be caused by several issues. Check for a broken, bent, or worn cutter blade and replace it if necessary. Ensure the cutter blade-tightening nut is securely tightened. Also, verify that the convex part of the cutter blade and cutter blade support fitting are securely attached. If the vibration persists, the drive system may be abnormal, requiring professional inspection and maintenance.

      If the cutter blade on your Dolmar Brush Cutter isn't rotating, first check if the cutter blade-tightening nut is loosened and tighten it securely. Also, inspect for any twigs caught by the cutter blade or dispersion-preventing cover and remove any foreign matter. If the issue continues, the drive system may be abnormal, requiring professional inspection and maintenance.
