n Wash the air lter with warm, soapy water.
n Rinse and squeeze to dry.
n Reinstall the air lter.
Make sure the lter is seated properly inside the
cover. Installing the lter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
n Reinstall the cover.
n Tighten knob to secure.
See Figure 18.
The cultivator uses NGK BPMR7A or Champion RCJ-6Y spark
plug (34). Use an exact replacement and replace annually.
n Remove the spark plug boot.
n Loosen the spark plug by turning it counterclockwise with
a socket.
n Remove the spark plug.
n Hand thread the new spark plug, turning it clockwise.
n Tighten with a socket and torque to 170 in. lb. minimum,
190 in. lb. maximum. Do not overtighten.
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.
The mufer is equipped with a spark arrestor screen inside
mufer body. After extended use the screen can become dirty
and may need to have the mufer replaced by an authorised
servicing dealer.
To avoid a re hazard, never run the cultivator without the
spark arrestor in place.
Depending on the type of fuel used, the type and amount of
oil used, and/or your operating conditions, the exhaust port
and mufer may become blocked with carbon deposits. If you
notice a power loss with your petrol powered tool, a qualied
service technician will need to remove these deposits to
restore performance.
The following steps should be taken before storing the
cultivator for the season.
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 ow.
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.
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.
n Clean the air lter as previously described.
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 following steps should be taken before using the cultivator
after it has been stored.
n 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.
n Pull the starter cord three or four times to clean oil from
the combustion chamber.
n Remove spark plug from the cylinder. Wipe oil from the
spark plug and return it to the cylinder.
n Reconnect spark plug wire.
n Follow the steps on the guidelines in “Assembly” and
“Operation” sections to refuel and restart the cultivator.
