MAINTENANCE
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.
You can often make adjustments and repairs described here.
For other repairs, have the trimmer serviced by an authorized
service dealer.
CLEANING THE AIR FILTER
See Figure 16.
Clean the air filter as indicated by the maintenance schedule.
To clean the air filter:
Loosen the air filter cover by turning the knob counter-
clockwise.
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 17.
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
threading will seriously damage the product.
IDLE SPEED ADJUSTMENT
See Figure 18.
WARNING:
The tines will move when adjusting the idle speed. Wear
all protective clothing and keep all bystanders, children,
and pets at least 50 ft. away. Make adjustments with the
unit supported by hand so the tines do not contact the
ground or any object. Keep all parts of your body away
from the tines and muffler. Failure to follow these instruc-
tions could result in serious personal injury.
If the tines turn at idle, the idle speed screw needs adjusting
on the engine. Turn the idle speed screw counterclockwise
to reduce the idle RPM and stop the tine movement. If the
tines still move at idle speed, contact a service dealer for
adjustment and discontinue use until the repair is made.
WARNING:
The tines should never turn at idle. Turn the idle speed
screw counterclockwise to reduce the idle RPM and stop
the tines, or contact a service dealer for adjustment and
discontinue use until the repair is made. Serious personal
injury could result from the tines turning at idle.
CLEANING THE EXHAUST PORT, MUFFLER,
AND SPARK ARRESTOR
NOTE: Depending on the type of fuel used, the type and
amount of lubricant used, and/or your operating conditions, the
exhaust port, muffler, and/or spark arrestor screen may be-
come 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.
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.
STORING THE PRODUCT
The following steps should be taken before storing the cul-
tivator 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 car-
buretor. Run the engine until it stops. This helps prevent
gum deposits from forming inside the carburetor and
possible engine damage.
