Why won't my Makita EM3400U engine start?
- C
  Clifford SalazarAug 23, 2025
  Several factors can prevent your Makita Trimmer from starting. Ensure the I-O switch is set to START. If it is, try pushing the primer pump 7 to 10 times. Also, make sure you are pulling the starter rope strongly and that there is enough fuel in the tank. Check that the choke is in the correct position: "CLOSE" for a cold start and "OPEN" for a warm start. Other potential causes include a clogged fuel filter (replace it), a bent or blocked fuel tube (straighten or replace it), or deteriorated fuel (replace with new fuel, recommended every month). A detached plug cap (attach it securely), a contaminated spark plug (clean it), or an abnormal spark plug clearance (adjust it) or abnormality (replace it) can also be the reason.

  If your Makita Trimmer engine stops quickly or doesn't reach full speed, start by warming up the engine adequately. Ensure the choke lever is set to "OPEN" if the engine is already warm. Also, check the idle speed and adjust it if it's too low. A clogged fuel filter (replace it) or a dirty air cleaner (clean or replace it) could also be the cause.
