If the walk tractor is idle for a long time, there will be a series of problems and failures. In order to avoid failures when it is used again, pay attention to maintenance measures.
1. Parking place. It is best to put it in the warehouse, but do not put it together with chemical fertilizers and pesticides, so as not to corrode the parts; if you park it outdoors, you should choose a high, dry and ventilated place, and cover it with a covering such as plastic sheeting to prevent mechanical damage and rust.
2. Pad mechanism. Pad the tractor with wooden piers or masonry to reduce the load on the tires; if the pads are not supported, the tires should be inflated by 10% to 20%, and should be checked frequently, often inflated, and not short of air.
3. Wash thoroughly. Remove the dirt and oil stains on the surface of the tractor, and comprehensively check, adjust, and tighten all parts and screws to avoid loosening and falling off.
4. Drain the oil. After the tractor is out of use, all the cooling water, diesel oil, oil, etc. in the engine should be drained.
5. Maintenance parts. Take an appropriate amount of dehydrated oil (heat the oil to about 130°C) and pour it into the intake pipe, turn the crankshaft, and make the oil adhere to the piston, piston rod, cylinder liner and valve. 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 lose their performance.
6. Remove the injector. After cleaning the injector, put it into clean diesel oil, loosen the adjusting screw, and block the injector hole with a wooden plug.
7. Oil the axle box. Take 1kg of dewatered oil, pour it into the crankcase, and then shake the crankshaft several times to make the lubrication system full of dewatered oil.
8. Parts polyester oil. Coat all fastening parts such as rocker arm, high-pressure oil pipe, fuel injector, bolts and nuts with dewatering oil to prevent rust.
9. Lubricate well. According to the overall lubrication requirements of the walking tractor, select the lubricating oil that meets the standard for sufficient lubrication.
10. Wrap up dustproof. Place the engine's air filter, exhaust duct, water tank port, fuel tank port, etc. where it is easy to enter the soil and dust, and bundle it with plastic cloth or oil paper to prevent debris and dust from entering.
11. Note [1]. First of all, keep the battery vents unblocked, because hydrogen and oxygen are generated during the use of general-purpose batteries, and if the vents are blocked, the battery may rupture. Secondly, pay attention to the liquid level of the battery. The normal liquid level should be 10-15 mm higher than the plate. Unused batteries should be stored in a cool and ventilated place.
