MAINTENANCE
WARNING
Never operate a damaged or defective cultivator.
WARNING
Improper maintenance will void your warranty.
NOTICE
For Emission control devices and systems, read and
understand your responsibilities for service as stated in the
Emission Control Warranty Statement of this manual.
How to Check, Clean and Change the Air
Filter
Check the air filter every 25 hours of use or more frequently if
used under dusty conditions. A clogged air filter may increase fuel
consumption while cutting down the engine power. Never operate
the cultivator without the air filter or with a deformed filter element
because unfiltered dust will damage the engine.
Cleaning Air Filter
1. Remove the air cleaner cover by pulling the tab on side and
take out the filter element.
2. Use mild detergent and warm water to clean the filter
element. After cleaning, air dry the element completely and
moisten with a small amount of motor oil.
3. Place the filter element into the air cleaner housing and press
the cover against the housing until it clicks.
Idle Speed Adjustment
1. Warm up engine before adjusting idle speed.
2. The idle speed adjustment screw controls the throttle opening
at idle position.
3. When the engine tends to stop frequently at idling mode, turn
the adjusting screw clock wise.
4. If the tines continue to rotate after releasing the trigger, turn
the adjusting screw counter-clockwise.
Clear Blockages From the Fuel Line & Filter
1. After you’ve used your cultivator for a few seasons, check for
blockages in the fuel tank and fuel filter. Such blockages can
keep your cultivator from starting and running properly.
2. Clear any blockages you see in the tank or fuel line, replace
the fuel filter if needed.
NOTICE
The fuel filter is located inside the tank.
Spark Plug
Starting failure and mis-firing are often caused by a fouled spark
plug. Clean the spark plug and adjust the plug gap to
0.020-0.028 in. (0.5-0.7 mm) if necessary.
– To install the spark plug first turn the plug until it is finger
tight, then tighten it a quarter turn more with a ¾ in. (19 mm)
socket wrench.
CAUTION
DO NOT overtighten the spark plug.
NOTICE
The cultivator uses NHSP L8RTC or NGK BPMR7A spark plug.
Use an exact replacement and replace annually.
Muffler
Inspect periodically the muffler for loose fasteners, any damage
or corrosion or blockage caused by insect nests. If any sign of
exhaust leakage is found, stop using the machine and have it
repaired immediately.
WARNING
Note that failing to do so may result in the engine catching on
fire.
