100380 - REAR TINE TILLER
Once oil has been added, a visual check should show oil about
1-2 threads from running out of the fill hole.
If using the dipstick to check oil level, DO NOT screw in the
dipstick while checking.
Check oil often during the break-in period. Refer to the
Maintenance section for recommended service intervals.
The engine is equipped with a low oil shut-off and will stop
when the oil level in the crankcase falls below the threshold
level.
We consider the first 5 hours of run time to be the break-
in period for the engine. During the break in period we
recommend using standard automotive non-synthetic blended
oils. After the break in period synthetic oil can be used but is
not required. Adjusting throttle setting will increase/decrease
engine speed helping to seat piston rings. Avoid bogging
or lugging the engine down and avoid prolonged running at
constant RPM. After the 5 hour break-in period, change the
oil. Using synthetic oil does not increase the recommended oil
change interval.
Weather will affect engine oil and engine performance. Change
the type of engine oil used based on weather conditions to suit
the engine needs.
Synthetic oil may be used after the 5 hour initial break-in
period. Using synthetic oil does not increase the recommended
oil change interval. Full synthetic 5W-30 oil will aid in starting
in cold ambient <5º C (41º F).

Air Cleaner Maintenance
A dirty air cleaner can restrict air flowing into the carburetor. To
keep the carburetor in good working conditions, please service the
air cleaner periodically. If operating the engine in extremely dusty
area, servicing should be done more often.
Never clean the air cleaner element with gasoline or low flash-
point detergents, an explosion may happen.
Never run the engine without an air cleaner. Dirty air entering
the engine can speed up engine wear.
1. Remove the air cleaner cover and take the element out.
2. Paper element: Wash the element with home detergents and
warm water (or non-flammable or high flash-point cleansing
solvents) and dry.
Foam element: Soak in clean engine oil until saturated.
Squeeze out excess oil; otherwise, the engine will smoke
when starting.
3. Clean the air cleaner cover and inner surface with a damp
cloth, be careful not to allow dust to enter the carburetor.
4. Reinstall the element and reinstall the air cleaner cover.
Spark Plug Service
Spark plug type: F6RTC/F6TC/F7RTC/F7TC
For normal engine operation, ensure the spark plug gap is correct
and check for carbon deposit around the spark plug.
1. Remove the spark plug cap.
2. Clear away dirt around the spark plug base.
3. Dismantle the spark plug with a spark plug wrench.
4. Visually check the spark plug. Clean with a steel brush. If the
insulator is damaged, replace the spark plug.
5. Measure the spark plug clearance with a spark plug gap
gauge. The clearance should be 0.7-0.8 mm. If adjustment is
necessary, bend the side electrode carefully.
6. Check if the spark plug gasket is in good condition. To
prevent cross threading, screw in by hand.
7. Screw in the spark plug to the bottom first by hand and then
screw in by a spark plug wrench and compress the gasket.
7a. If a new spark plug is used, twist another 1/2 turn after
compressing the gasket.
7b. If reinstalling a used spark plug, only twist another 1/8-
1/4 turn.
