  If your Nakayama Trimmer fails to start, several factors could be at play. It might be due to incorrect fuel; in this case, drain the old fuel and refill with the correct type. Alternatively, a clogged fuel filter could be the culprit, requiring a cleaning. Other potential issues include the spark plug being fouled or wet (clean or dry it), an incorrect spark plug gap (adjust to 0.65 mm), or a disconnected spark plug (retighten it). Finally, the trimmer might be out of its normal range, which requires adjustment.

  If your Nakayama Trimmer engine won't reach its maximum output, consider these potential causes: A fouled plug with carbon residue or an excessive gap may be the reason; clean the plug, check its thermal value, and set the gap between 0.6 and 0.7 mm. The carburetor or its jets might be fouled, needing a cleaning. Also, ensure it's not clogged with dust, requiring a clean. Inspect the exhaust pipe for carbon residues, removing them if present. A poor fuel mix with too much oil can also hinder performance; refuel according to the instructions.

What to do if the engine of my Nakayama PS5170 Trimmer will not stop?

  If the engine of your Nakayama Trimmer doesn't stop, the issue might stem from a pale grey plug with white marks, indicating the need for a plug with a higher thermal value. Another possibility is carbon residue in the ignition area, which necessitates cleaning the cylinder head, piston base, and cylinder engine block.

Why does my Nakayama PS5170 Trimmer chain saw run but not cut?

  Mr. Paul SanchezSep 3, 2025
  When your Nakayama Trimmer chain saw runs but doesn't cut effectively, or if there's insufficient chain lubrication, verify that the chain isn't fitted in reverse on the guide bar, referring to the assembly instructions for correct installation. Also, ensure the oil tank is adequately filled. Lastly, check for a clogged oil guide groove and clean it if necessary.
