Early spring is the season for deep plowing and land preparation, and tractors are indispensable agricultural machinery at this time. Many operators will make some misunderstandings when starting tractors in cold seasons, which will bring great hidden dangers to the machine body and personnel. The following is a summary of common misunderstandings in starting tractors, which can be used as a reference for the majority of operators.
1. Heating the fuel tank with an open flame.
Heating the fuel tank with an open flame will not only damage the paint on the surface of the machine body, lose the protective effect such as rust prevention, and shorten the service life; it is also easy to burn the plastic oil pipe and cause oil leakage. If you don't pay attention, it will cause the gas in the fuel tank to expand rapidly, causing an explosion, causing damage to the machine body and casualties.
2. Baking the oil pan with an open flame.
Baking the oil pan with an open flame will shorten the service life of the engine, and it is easy to deteriorate the engine oil, reduce the lubrication effect, and affect the normal operation of the tractor.
3. Not adding cooling water when starting.
If cooling water is not added during startup and is added after startup, the water tank will suddenly encounter cold water under high temperature conditions, causing cracks in the engine body and cylinder head.
4. Add engine oil from the intake pipe.
Adding engine oil from the intake pipe will cause carbon deposits on the piston and piston ring, shortening the service life of the intake pipe.
5. Remove the air filter and start the engine.
This operation will allow unclean air to enter the cylinder, valve and other moving parts, aggravating the wear of these parts.
6. Forced start with other power without preheating.
Forced start of a single-cylinder diesel engine without preheating will cause dry friction or semi-dry friction between the crankshaft and the bearing, which can easily cause the crankshaft to seize and become unusable.
