Due to wear from running, friction and change of load, the 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 tiller. In order to keep the above adverse conditions to a
minimum level, it is necessary to strictly and regularly conduct maintenance of the tiller, so that it can
maintain a good technical condition and have a longer service life.
I Running in:
1. Please refer to the manual for information about running-in of the gasoline engine.
2. A new or overhauled tiller shall work for one hour without load first, then work for another
five hours, and when the engine is still warm, drain all engine oil in the crankcase of the
gasoline engine. Then fill the engine with engine oil as per the steps 1 and 2 of ChapterⅡ, and
run for 4 hours for running in, then the machine can be used for normal farming.
II Technical maintenance of tiller
1. Maintenance per shift (before and after each shift of work)
1) Listen and watch to check if there is any abnormal phenomenon like abnormal noise,
overheating, loose bolts, etc.
2) Check if there is any oil leakage from the gasoline engine and transmission box
3) Check if oil levels of the gasoline engine and transmission box are between the upper and
lower marks of their oil level indicators.
4) Timely remove dirt, slime, weeds and oil stains on the whole machine and its accessories
