MAINTENANCE
WARNING:
When servicing, use only identical replacement parts. Use
of any other parts may create a hazard or cause product
damage.
WARNING:
Always wear safety goggles or safety glasses with side
shields during power tool operation or when blowing dust.
If operation is dusty, also wear a dust mask.
WARNING:
Before inspecting, cleaning or servicing the machine, shut
off engine, wait for all moving parts to stop, and disconnect
spark plug wire and move it away from spark plug. Failure
to follow these instructions can result in serious personal
injury or property damage.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most plastics
are susceptible to damage from various types of commercial
solvents and may be damaged by their use. Use clean cloths
to remove dirt, dust, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal injury.
Only the parts shown on the parts list are intended to be repaired
or replaced by the customer. All other parts should be replaced
at an Authorized Service Center.
CLEANING THE AIR FILTER
See Figure 17.
Clean the air filter as indicated by the maintenance schedule.
To clean the air filter:
Loosen the air filter cover by turning the knob counterclock-
wise.
Remove the air filter cover.
Remove the air filter.
Lightly tap or blow out dirt particles from filter.
Reinstall the air filter.
NOTE: Make sure the filter is seated properly inside the
cover. Installing the filter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
Reinstall the cover.
Tighten knob to secure.
NOTE: For best performance, the air filter should be replaced
once each year.
REPLACING THE SPARK PLUG
See Figure 18.
The cultivator uses Champion RCJ-6Y or NGK BPMR7A spark
plug. Use an exact replacement and replace annually.
Remove the spark plug wire.
Loosen the spark plug by turning it counterclockwise with
a socket.
Remove the spark plug.
Hand thread the new spark plug, turning it clockwise.
Tighten with a socket and torque to 170 in. lb. minimum,
190 in. lb. maximum. Do not overtighten.
CAUTION
Be careful not to cross thread the spark plug. Cross thread-
ing will seriously damage the product.
REPLACING THE SPARK ARRESTOR
The spark arrestor must be cleaned or replaced every 50
hours or yearly to ensure proper performance of your product.
Spark arrestors may be in different locations depending on
the model purchased. Please contact your nearest service
dealer for the location of the spark arrestor for your model.
CLEANING THE EXHAUST PORT AND MUFFLER
Depending on the type of fuel used, the type and amount of
lubricant 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, you
may need to remove these deposits to restore performance.
We highly recommend that only qualified service technicians
perform this service.
STORING THE PRODUCT
The following steps should be taken before storing the cultiva-
tor for the season.
Fuel Tank:
Drain the fuel tank completely into a container approved for
gasoline. 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.
Restart the engine to make sure no fuel is left in the carbu-
retor. 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, 2-cycle lubricant 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 dis-
connected.
