MAINTENANCE AND STORAGE
Intake Air Cooling Vent
– Never touch the cylinder, muffler, or spark plugs
with your bare hands immediately after stopping the
engine. The engine can become very hot when in
operation, and doing so could result in severe burns.
– When checking the machine before using it, check
the area around the muffler and remove any debris.
Failing to do so could cause the muffler to become
overheated, and that this in turn could cause the
engine to catch on fire. Always make sure that the
muffler is clean and free of debris before use.
– Check the intake air cooling vent and the area around
the cylinder cooling fins after every 25 hours of use
for blockage. Note that it is necessary to remove the
engine cover in order to view the upper part of the
cylinder.
Procedures to be Performed After Every 100 Hours
of Use
1. Remove the muffler, insert a screwdriver into the
vent, and wipe away any carbon buildup. Wipe away
any carbon buildup on the muffler exhaust vent and
cylinder exhaust port at the same time.
2. Tighten all screws, bolts, and fittings.
3. Check to see if any oil or grease has worked its way
in between the clutch lining and drum, and if it has,
wipe it away using oil-free, lead-free gasoline.
Each fall — or before you store your cultivator for any
long period — be sure to take these measures:
1. Do not store your cultivator with fuel still in it.
Even under ideal conditions, stored fuel containing
ethanol or MTBE can start to go stale in as little as
30 days. Since stale fuel has a high gum content, it
can clog the carburetor, this, will in turn restrict fuel
flow. So, when you’re ready to store your cultivator,
or will not be using it for more than 2 weeks, drain
the fuel tank completely.
Cultivator Storage
You can store the unit with 50:1 TruFuel because
it is pretreated with stabilizer and has NO ethanol
content.
NOTE
2. Remove fuel from the carburetor and fuel lines
by starting the engine and letting the cultivator
run out of fuel. This will prevent gum deposits
forming inside of the carburetor and possible engine
damage.
3. Disconnect spark plug wire and remove the spark
plug (use a 19 mm spark-plug wrench). Pour about
a teaspoon of clean, air-cooled, two cycle oil through
the spark-plug hole into the combustion chamber.
Slowly pull the starter cord two or three times to
coat the inside of the cylinder wall.
4. Inspect the spark plug, and, if necessary, clean it.
The cultivator uses NHSP L8RTC or NGK BPMR7A
spark plug. Use an exact replacement and replace
annually.
5. Install the spark plug, but leave the spark plug wire
disconnected.
6. Clean the air filter as described on page 14.
7. Clean dirt, grass, and other materials from the entire
machine.
8. Wipe the tines with oil or spray them with WD-40,
to prevent rusting.
9. Oil the throttle cable and all visible moving parts.
(Do not remove the engine cover.)
10. Store your cultivator — in an upright position — in a
clean, dry place.
11. Do you have fuel left over from last season? Dispose
of it properly. Buy fresh oil and gasoline next
season.
Before use
Wipe out fuel leaks, fuel spillage.
Inspect and clean fuel tank, air filter and fuel filter.
Every 25 hours
Clean cylinder fins and intake air cooling vent.
Every 50 hours
Clean and readjust spark plug gap (gap: 0.5 - 0.7 mm
{0.020 - 0.028 in.} replace if necessary).
Clean exhaust port.
Annually
Replace spark plug.
