Product Information

Throttle (9) adjusts the amount of air drawn into the carburetor. Its amount affects the power that the engine develops. The damper (7) is used for cold start. It must be closed if you intend to start the unit. After the engine has started, it needs to be opened, otherwise, the motor will immediately stall. To eliminate problems with air purification, it is necessary to replace the defective filter or rinse the existing one (serviceable). The filter must be washed in soapy water and dried. When to adjust To eliminate clogging, you will have to disassemble the carburetor and clean the membrane. Strainer clogging The membrane can undergo deformation during prolonged operation of the unit and when using aggressive fuel. Throttle and air dampers mostly wear out due to the presence of abrasive particles in the air. Defective flaps look like they were sandblasted.

If dirt accumulates in the adjustment cavity, the inlet needle cannot close the hole tightly and a lot of fuel is poured into the chamber. Lawn mowing carburetor is a unit in the power system. In it, like any carburetors, there is a process of mixing air and fuel (gasoline) for further supply to the engine cylinders. This ensures reliable starting and trouble-free running. The ignition system is fully encapsulated and thus proof against damp and dirt. Manual fuel pump (Purger) The 420mm of cutting width is perfect for small-medium gardens and is compact enough strim away at those tight edges. Start and control with one hand Gasoline through the float chamber and nozzle tube with narrowing. A camera with a float adjusts the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the tube with narrowing is already low. Due to the pressure drop, fuel enters through the nozzle.Also necessary set cord suitable diameter in the trimmer coil or install knives. this is done so that during the tuning process the engine has at least some kind of load. After installing the cutting tool and starting the gasoline engine, let it warm up for 10 minutes. Since the volume under the control membrane (18) is connected with atmospheric air through the channel (19), the membrane goes up, opening the valve (14) by means of the lever (17). After opening the valve (14), a new portion of fuel enters the chamber (16).

This fact causes air leaks. The position of the throttle (9) determines the amount of air entering the carburetor chamber, as well as engine power and the number of revolutions. As a result of wear of the dampers, engine performance decreases, malfunctions appear in its operation, piston rings, piston and cylinder cover wear out. Throttle and air damper shaft wear For a more pleasant implementation of abilities, it is more convenient to discern the work of an experienced user:To eliminate this trouble, adjustment will be required. With the engine running, give full throttle, then turn the “H” knob to the right until the reduction in speed begins. After that, the “H” knob must be slowly turned to the left until you hear the engine running unevenly. Then turn the “H” knob to the right until the engine runs smoothly.

The basis of the carburetor of the lawn mowers is an aluminum case. It contains a diffuser (a hole with internal contours). Air is blown through this hole. The oxygen (air) flow rate depends on the cross-section (passage opening) of the diffuser. Due to hit poorly cleaned air, The shaft wears out and may break. Broken parts of the shaft can enter the combustion chamber or crankcase and cause serious damage to the entire piston system.A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required following extended breaks in operations. Loop handle (R) Also, the aforementioned consequences for the engine may cause clogging of the pump cavity with impulse side. In this case, dirt enters the membrane through the pulse channel. The smaller this hole, the faster the air flows, and the higher the level of its rarefaction in the zone with the smallest diameter. It is curious that, based on the beliefs of the creator of the video, the setting (its correctness) is determined by the color of the candle, and not just by the speed and stability of the motor.

Pulse channel (1) connects the impulse chamber of the pump to the crankcase, namely, to its internal volume. The piston located in the cylinder, making a reciprocating motion, successively changes the pressure in the crankcase (vacuum or pressure increase). Pressure drops make the membrane move (4). Therefore, the operation of the pump is synchronized with the operation of the engine.Lower T knob (LA) used to set idle speed. By turning it to the left, the engine speed will begin to decrease, and when you turn the regulator to the right, the speed will increase. lawn mowers, like all gasoline powered tools for the garden, are not difficult to maintain. It is possible and necessary to repair, configure yourself. For example, adjusting the carburetor lawn mowers do it yourself. a matter of five minutes. A thorough cleaning and rinsing of the strainer will be required to resolve the malfunction. Also recommended blow with compressed air all openings in the trimmer carburetor body. Adjustment lever defective If at idle You noticed that the cutting tool rotates, therefore, it is necessary to reduce the engine speed. This is done using the lower idle control, often marked with the letter “T”. The figure below shows the placement of the knobs on the Husqvarna trimmer.
