  Linda HarrisAug 14, 2025
  If your Spear & Jackson Chainsaw won't start or starts but won't run, there are several potential causes. Ensure you are following the correct starting procedures as outlined in the User Guide or the checklist on page 14. The spark plug may be fouled, in which case you should clean, gap, or replace it. A blocked fuel filter can also cause this issue, so replace the fuel filter. Finally, check if the chain brake is engaged and disengage it by pulling the chain brake.

  If your Spear & Jackson Chainsaw starts but the engine has low power, the choke lever position may be incorrect. Move it to the RUN position. Another cause could be a dirty air filter; remove, clean, and reinstall it. It is also possible that carburetor mixture adjustment setting is incorrect and you should have it adjusted by an Authorised Service Centre.
