The steering column itself is adjustable for the height of the owner.
The center of gravity of the device is located low enough to carry out control without any effort.
Additional details and accessories are provided that ensure the multifunctionality of the Cascade unit (walk-behind tractor). The instruction says about the ability to process even virgin soil.
The presence of a trolley will allow transporting tools, containers to the place of work.
Modern requirements put forward for the operation of the presented equipment are fully implemented. They are confirmed by ISO 9002 quality certificate.
Motoblock maintenance
To ensure the efficiency and safety of operation will allow regular maintenance of equipment.
Such work involves, if necessary, changing the oil, checking the engine, adjusting the control, updating the oil seal of the Cascade motoblock gearbox, etc.
If the unit is new, it must be run in sparing mode in order to enable all components to rub against each other. This will avoid the rapid wear of engine components, other moving parts, as well as gearbox elements of the Cascade motoblock, its stuffing box and other elements.
At the first start-up of the equipment, it is necessary to add oil to the crankcase. The mixture used in the Cascade motoblock must have a certain viscosity according to SAE and API classification.
The grease should be designed for four-stroke gasoline engines. Which oil should be used in the Cascade walk-behind tractor, SunGarden answers and recommends the brands ST, SG, SH, SJ, SL, SM.
The first replacement should be carried out after 2-5 hours of operation of the unit.
Walking tractor adjustment
According to the requirements of the manufacturer’s instructions, after the end of the first season of operation, the equipment should be adjusted.
This action is performed in the area of the fuel system, valves and carburetor of the Cascade motor-block.
This is a rather complicated process, therefore it is necessary to study the adjustment technology quite carefully.
In the first year of operation, the equipment does not require any additional actions and interventions in the system. Factory parameters ensure the stability of the operation of such an aggregate as the Cascade walk-behind tractor during the season. Customer reviews indicate a fairly good quality of equipment, even without additional settings, up to 4 years.
However, if there are malfunctions, instability of the engine speed of the Cascade motor-block engine, carburetor adjustment will be required already in 2 years of operation.
Such a procedure will be needed after prolonged exertion or, conversely, inaction.
Carb adjustment technology
Before starting, warm up the engine. The carburetor is being adjusted in stages on the Cascade motoblock. 2 screws of the minimum and maximum gas are screwed in until they stop, and then are unscrewed by one and a half turns.
The gear lever is set to minimum stroke, but the engine should continue to operate.
The throttle screw should be used to set the minimum engine idle cycle .
The engine should be free of noise and stops.
Using screws to adjust the level of fuel entering the carburetor of the Cascade motoblock will not be difficult. Tightening the screw will enrich the fuel, and loosening it will increase the air in the mixture.
Adjusting the fuel level of the carburetor of the Cascade motor-block should be carried out regularly (at the end or beginning of the season).
The essence of adjustment
Engine turns are regulated by the idle screw. This will allow you to adjust the maximum speed. The same principle applies when setting their minimum value. This is done by changing the closing angle of the valve of the Cascade walk-behind tractor.
The gear lever, switched to the "gas" mode, allows you to adjust the ideal engine stroke. The maximum allowable number of revolutions of the screw does not exceed 2.5.
The correct settings can easily be checked by the appearance of the spark plug. After working in load mode for a short period of time on the part should not be soot or traces of fuel.
However, such undesirable effects depend not only on the tuning of the carburetor mixture. A malfunction in the ignition or cooling system can cause similar effects on the spark plugs.
Carburetor cleaning
When the fuel does not reach the carburetor in sufficient quantities, it is necessary to carry out cleaning during the setup process.
The device of the "Cascade" walk-behind tractor involves removing the hose from the inlet fitting. For K45 carburetor, it is enough to press on the gasket so that gasoline begins to pass through the hole.
You must also process the coarse filter. To do this, the fuel supply valve is unscrewed and completely disassembled. All parts are processed with gasoline. After that, all the elements are collected.
If fuel from the carburetor does not enter the cylinders, you will have to revise the fuel valve. The cause of this phenomenon may also be the presence of contamination on the jets.
Carburetor type KMB-5
To adjust the carburetor KMB-5 motoblock "Cascade" there is a certain tuning technology.
Initially eliminate gasoline from the float cavity. An air mixture is fed through the fuel inlet.
Adjusting the carburetor KMB-5 motoblock "Cascade" will require its installation in the working position. When air is supplied, its movement must be unobstructed. When the part is turned over, the purge stops completely.
In the case when such actions occur without deviations, the carburetor operation is considered adjusted.
Carburetor K-60
Carburetor tuning should be strictly according to the manufacturer's instructions for a specific model. Otherwise, you can simply break the equipment.
The K-60 carburetor is used in the M-3 model. He will require to install the throttle so that the gap between its base and the duct is 2-2.5 mm wide. It can be seen through the pipe of such an aggregate as the Cascade motor-block. Adjustment of the carburetor will require clamping the tuning screw and turning it 0.5-1 turn.
Then engine 5 min. warm up and turning the adjusting screw, expect a decrease in engine speed. This is the optimal position. To determine it at minimum speed, the rotation speed is reduced and, smoothly turning the screw, find its optimal position.
Knowing the principle of operation and the main characteristics of the unit, it is possible to effectively and safely use such equipment as the Cascade walk-behind tractor. Adjustment of the carburetor should be carried out as necessary in accordance with the manufacturer's instructions.
Setting the operation of this component of the equipment will ensure the stability of the engine speed after prolonged loads or inactivity. The presented walk-behind tractor is guaranteed to last a long time, and the actions performed with its help will not require large expenditures of physical strength. Proper care and adjustment of the unit will allow you to not know emergency situations during the processing of land.
