If the walking tractor is left unused for a long time, a series of problems and failures will occur. In order to avoid failure when it is used again, pay attention to maintenance measures.
1. Parking place. It is best to store it in a warehouse, but do not put it together with chemical fertilizers and pesticides, so as not to corrode the parts; if parked outdoors, choose a high-rise, dry and ventilated place, and cover with plastic sheeting to prevent mechanical damage And rust.
2. Supporting parts. Padded the tractor with wooden piers or masonry to reduce the load on the tires; if the padded is not supported, the tires should be inflated by 10% to 20%, and the tires should be checked frequently. Inflation is necessary and air is indispensable.
3. Wash thoroughly. Remove the dirt and oil on the surface of the tractor, check, adjust, and tighten all parts and screws comprehensively to avoid loosening and falling off.
4. Put clean oil and water. After the tractor is out of service, drain the cooling water, diesel, and oil in the engine.
5. Maintain the parts. Take proper amount of dehydrated engine oil (heat the engine oil to about 130°C) and pour it into the intake pipe, rotate the crankshaft to make the engine oil adhere to the piston, piston rod, cylinder liner and valve. And shake the piston to the top dead center of compression to prevent the valve spring, push rod and other parts from being compressed for a long time and losing their performance.
6. Remove the fuel injector. After cleaning the fuel injector, put it into clean diesel oil, loosen the adjusting screw, and block the fuel injector hole with a wooden plug.
7. The axle box is filled with oil. Take 1kg of dehydrated oil, pour it into the crankcase, and then shake the crankshaft several times to fill the lubrication system with dehydrated oil.
8. Parts are oiled. Coat all fastening parts such as the rocker arm, high-pressure oil pipe, fuel injection ju, bolts and nuts with dehydrated oil to prevent rust.
9. Good lubrication. According to the overall lubrication requirements of the walking tractor, use standard lubricants for full lubrication.
10. Bandage to prevent dust. Tie the engine's air filter, exhaust duct, water tank port, fuel tank port and other places that are easy to enter dirt and dust, and tie them firmly with plastic cloth or oil paper to prevent entry of debris and dust.
11. First of all, keep the battery vents unobstructed, because hydrogen and oxygen are generated during the use of general-purpose batteries. If the vents are blocked, the battery may rupture. Secondly, pay attention to the battery liquid level, the normal liquid level should be 10-15 mm higher than the plate. Unused batteries should be stored in a cool and ventilated place.
