The engine lacks power or is not running smoothly – 6.5HP Chipper

Last Updated on August 6, 2020 by Forest Master

In the event that your wood chipper wonโ€™t start, please follow this checklist:

Check that the Throttle Lever is in the ‘RUN’ position

Is the air filter clean? If it’s dirty, change it by following the instructions provided in the engine manufacturer’s owner’s manual.

Is the spark plug clean? If it’s fouled or cracked, change it. If it’s oily, leave it out, hold a rag over the plug hole and pull the recoil cord several times to blow out any oil in the cylinder, then wipe off the plug and reinsert it.

Are you using fresh and clean unleaded gas? If it’s old change it. Use a fuel stabilizer if you keep gas longer than 30 days.

Does your engine have the right amount of clean oil? If it’s dirty, change it following the instructions provided in the engine manufacturer’s owner’s manual.

Check the oil level and adjust as needed.


If youโ€™ve been through each step of this checklist and youโ€™re still experiencing issues, then please give us a call on our technical line on 0191 276 6553 or email us at technical@forest-master.com.
