  If your Dolmar Trimmer's engine stops shortly after starting or the engine speed doesn't increase, it might be due to insufficient warm-up (perform warm-up operation). Check that the choke lever is set to “OPEN” and not “CLOSE” after the engine is warmed up. Other potential issues include a clogged fuel filter (clean it) or a contaminated or clogged air cleaner (clean it). For abnormal carburetor or drive system you should make request for inspection and maintenance.

Also, check for a loosened metal blade-tightening nut (tighten securely) or a shifted convex part of metal blade and metal blade support fitting (attach securely). For abnormal drive system you should make request for inspection and maintenance.
