Motoblock is a complex device consisting of a large number of various components and assemblies. Therefore, an important point when operating such a device is its first launch. To avoid the occurrence of various breakdowns, it is necessary to learn how to start the walk-behind tractor correctly, especially after its long downtime, for example, after wintering.
How to start a walk-behind tractor after downtime
Before the first start of such equipment, especially after a long and time-consuming downtime, it must first be prepared for work. First, the walk-behind tractor should be unrolled in an open space (outside in the yard) and inspected for corrosion.
If there are traces of corrosion centers on the nodes and the metal surface of the unit, they must be eliminated immediately, and the problem areas should be treated with special compounds (rust converters) and painted. Then, before the first start-up of the equipment, it is necessary to carry out the following preparatory work:
- Remove the old one, which was filled before the preservation of the walk-behind tractor, with fuel from the tank.
- Clean the gearbox of old grease.
- Clean the gearbox of grease residues, rinse it, then dry it properly.
- Fill with fresh fuel, as well as transmission oil.
- Inspect the fuel hoses for various leaks and cracks. In an emergency, for example when significant blockages appear, they should be rinsed.
- Remove and wash the filters in gasoline. Then dry them and put them back in place. Worn or damaged filters should be replaced.
- Diagnose the carburetor (disassemble it, disassemble it, then blow it out with compressed air and clean it of dirt with gasoline, then reassemble it and install it on the walk-behind tractor walking).
- Completely diagnose drive belts for wear or large cracks. Worn or damaged belts should be replaced with new ones.
- Perform a full diagnosis of the GC device. It must be disassembled and a thorough inspection must be carried out for the presence of burrs and traces of rust on the surface of the walls of the device.
- Perform a thorough inspection of the spark plug. It must be unscrewed and ensure that there is no scale on its surface, as well as a variety of deposits. Then you need to ventilate the engine of the device. To do this, you need to stretch the starter cable several times towards you with sharp movements.
Then you need to make sure that the chassis of the walk-behind tractor is working, check the battery, as well as tire pressure. Before the first start, especially after a long standstill, you must make sure that the control systems of the walk-behind tractor are working.
Starting a walk-behind tractor with a gasoline engine
To start the walk-behind tractor after a long period of inactivity, which is equipped with a gasoline engine, you need to turn on the valve through which fuel is supplied. The fuel choke lever must also be activated (positioned opposite the START mark) and the clutch must be disengaged. After that, pumping is carried out with a manual starter (with the help of sharp movements, several times pull the cable towards you).
At the next stage, it is necessary to turn on the ignition and sharply pull the starter cable several times. After starting the internal combustion engine, the choke lever must be activated (switching to the “Running” mode). It should be noted that after a long standstill, the walk-behind tractor may not start on the first try. This is due to the fact that the parts and components of the unit must warm up properly.
Starting a walk-behind tractor with a diesel engine
Compared to gasoline walk-behind tractors, it is somewhat more difficult to start units with a diesel engine after a long period of inactivity. To start the device, which is equipped with a diesel engine, you need to unscrew the valve through which fuel is supplied. When the fuel begins to reach the nozzle, you need to put all the valves in the open position, then put the throttle lever in the middle position.
Then you need to pump fuel into the cylinder. To do this, press and hold the decompressor for a while. Then the decompressor is installed in its original place (to do this, it must be released and slightly stretched). Then you need to press the decompressor and sharply pull the jumper cable towards you. After the first start after a stop, the diesel unit should have some time to warm up. As a rule, this procedure takes no more than 10 minutes.
