time, use the following storage procedure:
1. Drain all fuel from the fuel tank into a
container with the same 2-cycle fuel
mixture. Do not use fuel that has
been stored for more than 60 days.
Dispose of the old fuel/oil mix in
accordance to Federal, State and

any high quality motor oil or 2-cycle
oil into the cylinder. Pull the starter
rope slowly to distribute the oil.
Reinstall the spark plug.

all of the oil from the cylinder
before attempting to start the
trimmer after storage.

it for any loose or damaged parts.
