STORING THE CULTIVATOR
The following steps should be taken before storing the
cultivator for the season.
Fuel Tank:
Drain the fuel tank completely if the cultivator will not be
used for more than two weeks.
Restart the engine to make sure no fuel is left in the car-
burettor. Run the engine until it stops. This helps prevent
gum deposits from forming inside the carburettor, which
subsequently can cause engine damage.
Spark Plug:
Disconnect spark plug wire and remove the spark plug.
Pour a teaspoon of clean, air-cooled, 2-stroke oil through
the spark-plug hole into the combustion chamber.
Leaving the spark plug out, pull the starter cord two or
three times to coat the inside of the cylinder wall.
Inspect spark plug, clean or replace as necessary.
Reinstall the spark plug, but leave the spark plug wire
disconnected.

Cultivator Body:
Clean dirt, grass, and other materials from the entire unit.
Wipe the tines with oil or spray them with silicone lubricant
to prevent rusting.
Oil the throttle cable and all visible moving parts. Do not
remove the engine cover.
Replace any badly worn or broken parts.
Store in an upright position in a clean, dry place. Store
with the handles in the extended position, or loosen handle
knobs and fold handles down. Do not allow throttle cable
to become pinched when lowering the handlebar.
Dispose any leftover fuel properly.
PREPARING FOR USE AFTER STORAGE
The following steps should be taken to prepare the cultivator
for use after it has been stored.
Unfold the handles into the upright position and secure by
tightening handlebar knobs. Do not allow throttle cable to
become pinched when raising the handlebar.
Pull the starter cord three or four times to clean oil from
the combustion chamber.
