cLEANiNG THE EXHAUST PORT AND
MUFFLER
Depending on the type of fuel used, the type and amount of
oil used, and/or your operating conditions, the exhaust port
and muffler may become blocked with carbon deposits. If
you notice a power loss with your gas powered tool, a quali-
fied service technician will need to remove these deposits
to restore performance.
STORiNG THE cULTivATOR
The following steps should be taken before storing the cul-
tivator for the season.
Fuel Tank:

Drain the fuel tank completely. Even under ideal condi-
tions, stored fuel containing ethanol or MTBE can start
to go stale in 30 days. Stale fuel has a high gum content
and can clog the carburetor and restrict fuel flow. The
fuel tank should also be drained 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-
buretor. Run the engine until it stops. This helps prevent
gum deposits from forming inside the carburetor and
possible engine damage.
Spark Plug:

Disconnect spark plug wire and remove the spark plug.
Pour a teaspoon of clean, air-cooled, -cycle 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 and clean or replace, as necessary.
 Reinstall the spark plug, but leave the spark plug wire
disconnected.
Air Filter:

Clean the air filter as previously described.
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.
 Order new parts to replace any that are badly worn or
broken.
 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.
 Properly dispose of any leftover fuel.
PREPARiNG FOR USE AFTER STORAGE
The following steps should be taken before using the cultiva-
tor 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.
 Remove spark plug from the cylinder. Wipe oil from the
spark plug and return it to the cylinder.
  Reconnect spark plug wire.
 Follow the steps on pages 10-1 to refuel and restart the
