n
Loosen the spark plug by turning it counterclockwise with
a socket.
n
Remove the spark plug.
n

threading will seriously damage the product.
spArk ArrEsTOr
The muffler is equipped with a spark arrestor screen inside
muffler body. After extended use the screen can become dirty
and may need to have the muffler replaced by an authorised
servicing dealer.
WArNINg:
To avoid a fire hazard, never run the cultivator without the
spark arrestor in place.
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 petrol powered tool, a qualified
service technician will need to remove these deposits to
restore performance.
sTOrINg ThE CulTIvATOr
The following steps should be taken before storing the
cultivator for the season.
Fuel Tank:
n
Drain the fuel tank completely. Even under ideal
conditions, 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.
n
Restart the engine to make sure no fuel is left in the
carburetor. Run the engine until it stops. This helps
prevent gum deposits from forming inside the carburetor
and possible engine damage.
spark plug:
n
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.
n
Leaving the spark plug out, pull the starter cord two or
three times to coat the inside of the cylinder wall.
n
Inspect spark plug and clean or replace, as necessary.
n
Reinstall the spark plug, but leave the spark plug wire
disconnected.
Air Filter:
n
Clean the air filter as previously described.
Cultivator Body:
n
Clean dirt, grass, and other materials from the entire unit.
n
Wipe the tines with oil or spray them with silicone lubricant
to prevent rusting.
n
Oil the throttle cable and all visible moving parts. Do not
remove the engine cover.
n
Order new parts to replace any that are badly worn or
broken.
n
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.
n
Properly dispose of any leftover fuel.

the combustion chamber.
