Air Filter

WARNING
Turn off ignition switch, and disconnect the spark plug before
performing maintenance except for carburetor adjustments.
Reconnect the spark plug wire after the service is done.
Your cultivator has been equipped with two (2) air filters
inside the air filter housing to prevent dirt and debris from
entering the engine.
Accumulated debris and dust in the air filters will reduce
engine performance, increase fuel consumption, and
increase the risk of damage to the engine. Inspect the air
filters frequently for dust and debris build-up, and clean the
air filters every 5 hours of operation (more frequently in dusty/
dirty conditions).
Both air filters should be cleaned by following these
instructions:
1. Before removing air filter cover, brush away any loose
dirt or debris on and around the filter cover.
2. Remove the screw securing the air filter cover. (Fig 13)
3. Remove and clean foam filter. (Fig 15)
• Light surface dust can readily be removed by
tapping the filter.
• Heavy deposits should be washed out in soap and
water. Squeeze out any remaining water and allow
the filter to completely dry.

Storage
To prevent fuel gum deposits and corrosion in the unit’s
carburetor and fuel system, it is highly recommended to use
a fuel additive/stabilizer formulated for ethanol fuels. Follow
the stabilizer manufacturer’s instructions. Run the engine at
least 5 minutes after adding stabilizer.
1.
Allow engine to cool and empty the fuel tank before
storing or transporting in vehicle. Use up remaining fuel in
the carburetor by starting the engine and letting it run until
it stops.
2. When not in use, store cultivator indoors in a dry
location. Store cultivator above the reach of children or
in a locked area out of the reach of children.
3. Store unit and fuel in area where fuel vapors cannot
reach sparks or open flames from water heaters, electric
motors or switches, furnaces, etc.
4. When preparing the cultivator for storage or when
cultivator will not be used for 30 days or more:
a. Empty fuel tank and use up remaining fuel in the
carburetor by starting the engine and letting it run
until it stops. Squeeze primer bulb several times to
purge fuel from carburetor.
b. Inspect and clean the cultivator thoroughly.
c. Lightly oil all external metal surfaces.
d. Remove the spark plug, place a few drops of
2-cycle engine oil into the cylinder. Pull the recoil
starter several times to distribute the oil. Replace
the spark plug.
e. Inspect and clean air filter as required.
WARNING
Never clean filter in gasoline or other flammable solvents.
4. Add a drop of thin oil to the filters and replace it.
5. Remove the paper air filter element.(Fig 16) Clean filter
by gently tapping it on a flat surface. Replace if
very dirty.
6. Reassemble the filter element and the air filter cover.
3. Visually inspect the spark plug for cracks or damage.
If damaged, replace spark plug with a recommended
replacement (see “Product Specifications”).
4. Clean carbon deposits. If excessive carbon build up,
replace spark plug.
5. Adjust the spark plug gap to 0.024 – 0.028 in.
(0.6 - 0.7mm).
6. Install the spark plug finger tight in the cylinder head,
and then tighten firmly with the spark plug wrench.
7. Re-install the insulated spark plug boot.
