2. Tilling in the irrigated field: when the length of “muddy foot” (i.e. the depth of the operator’s subsidence
into mud) is shorter than 25 cm, the wet soil rotary blade set can be used to till the field. If the length of muddy
foot is between 25 and 45 cm, the operator can use irrigated field rotary tilling roller to till the field.
vii. Precautions for use of mini tiller
1. Observe the working status of different parts and carefully listen to the machine’s sound, check to see if
connections of different parts are normal, because loose connection is not allowed. If any abnormal condition is
found, the operator should stop and check.
2. It is not allowed to work with heavy load right after cold start, especially when the machine is a new one
or an overhauled one.
3. Check the oil levels of engine and transmission box, if the oil levels in them are too low, replenish them
with engine oil.
4. Never try to cool the engine by pouring water on it.
5. When tilling, take care to prevent the mini tiller from falling over.
6. Never run a mini tiller equipped with rotary tilling blades on a beach or on a surface covered with
pebbles, or the blades will be damaged.
7. After using the mini tiller, make sure to remove the mud, weeds or oily grime on the mini tiller to keep
the whole machine clean.
8. Often clean the spongy element or steel mesh inside the filter and change its engine oil.
Chapter VII Maintenance of mini tiller
Due to wear from running, friction and change of load, the mini tiller’s bolts may get loose, and parts
and components may get worn, causing lower power of the gasoline engine, higher fuel consumption rate and
other faults that will affect use of the mini tiller. In order to keep the above adverse conditions to a minimum
level, it is necessary to strictly and regularly conduct maintenance of the mini tiller, so that it can maintain a
good technical condition and have a longer service life.
