Part 6 Applications
A.Running in and commissioning:
The newly purchased or overhauled garden management machine must be run in before it can be put into
full load operation. Otherwise, the wear of parts will be accelerated and the service life of parts will be
greatly shortened.
1.Preparation before running in
(1).Tighten the connecting bolts and nuts of all parts.
(2).Add fuel oil, lubricating oil and water.
(3).Check and adjust the tension of V-belt.
2.Running in method
(1).Under no load condition: each gear is running in for 0.5 hours.
(2).Under the condition of 1/3 rated load (rotary tillage depth 5-6cm): each gear is running in for 1 hour.
(3).Under the condition of 2/3 rated load (rotary tillage depth 8-10cm): the running in of each gear is 1.5h.
3.Work after running in
After running in, all lubricating oil in the gearbox shall be drained immediately while it is hot, and proper
amount of diesel oil shall be injected. The gear shall be cleared by idling in the second gear for 2-3

10
minutes. Then, the cleaned diesel oil shall be discharged and new lubricating oil shall be injected again,
so that the machine can be put into full load operation. (the diesel engine shall be run in according to the
requirements of the operation manual).
B.Operation:
1.Precautions before starting
(1).Check the preparation before starting according to the requirements of diesel engine operation manual.
(2).Check whether the fuel, lubricating oil and oil level of diesel engine meet the requirements.
(3).Check whether the lubricating oil and oil level in the gearbox meet the specified requirements.
(4).Check whether the throttle, clutch, gear change, tool control, steering and other gear operating systems
are normal.
(5).Check whether the bolts at the connecting parts are loose to ensure that they are tight.
(6).Turn the shift control lever to the neutral position, the tool control lever to the neutral position, pull
the clutch handle to the "off" position, and pull the throttle to the start position.
2.Start up
(1) Start the diesel engine according to the steps specified in the operation manual of the diesel engine.
(2) The diesel engine should be idle for three minutes without load.
(3) After the diesel engine runs normally, turn the tool control lever to the required position (i.e. ditching
or rotary tillage), then turn the gear lever to the required gear, and then smoothly lower the off shift
handle to the "on" position, and the machine can start to work. Check whether the left and right steering
gears are engaged. Inspection method: if you do not hold the steering handle and swing the armrest to the
left and right, it means that the steering gear teeth are engaged.
3.Shift gears
Pull the clutch handle to the "off" position and move the shift lever to the required gear. When shifting,
pay attention to:
(1).Shift only after stopping gear;
(2).When it is difficult to shift, the clutch will be slightly engaged, then completely separated, and then
put into gear;
(3).In general, only 1-2 grade can be selected for ditching, 1-2 for rotary tillage in hard land, and 2-3 for
soft dry land and paddy field. Otherwise, it will cause over load and affect the service life of the machine.
(4).When reverse gear is required for rotary tillage operation, the tool control lever must be turned to
neutral gear first, and then the slow reverse gear 1 can be engaged.
4.Steering
(1).Farming in the field and on the level road
-(a).Left turn: push the armrest to the right and pinch the left steering handle at the same time.
-(b).Right turn: push the armrest to the left and pinch the right steering handle at the same time.
(2).When going downhill on a large slope, special attention should be paid to it. It is better to use
manpower to push the handrail to turn left or right, because when turning on a steep slope, the operation
method is just opposite to that of turning on flat road, that is, pinch the left steering handle to turn the
machine to the right, and pinch the right steering handle to turn the machine to the left.
