High stick saw Referred to as a high-twist saw, it is one of the commonly used garden machinery for pruning trees in landscaping. It is a machine that is difficult and risky for single-person operation. Therefore, how to correctly use the high-twist saw is very important. 1. The recommended mixing ratio of fuel oil is 50:1 to 25:1 (must be stopped by high-quality air-cooled two-stroke oil). The smooth oil of the saw chain should participate in 10% to 30% of diesel (fire oil or light oil) ) Stop mixing and use again to ensure proper concentration. The proportion should be based on the amount of oil sprayed from the saw chain and to determine the level of participation, but it should be within the range of 10% to 30%. Second, the speed at idle speed should be adjusted according to the actual situation of the machine. The idle speed range is generally in the range of 2800~3500 rpm. It is particularly important to note that due to the use of safety, the machine's idle speed should be less than 1.25 times the machine's clutch speed ( The engine speed when the saw chain starts to run). Ordinary two-stroke mechanical fuel is mixed with steam engine oil (the engine oil is a two-stroke engine oil), the ratio of the specification is about 25:1, depending on the application status, if the application is not long If you work at a high speed, you can increase the concentration appropriately. If you often insist on high-speed rotation during operation, you should reduce the concentration appropriately and put more oil to ensure the normal smoothness of the external running parts of the cylinder. However, pay attention to removing the silencer in time to eliminate exhaust Carbon deposits in the airway to prevent excessive carbon deposits from entering the cylinder body and causing pulling cylinders. The above introduces several achievements that should be paid attention to in the application for reference ⒈When starting, the choke door should be opened when the car is cold, and the choke door is not necessary when the car is hot, and the manual oil pump pressure is more than 5 times. ⒉ Put the machine motor support and hook and loop on the ground, put it in a safe position, if necessary, put the hook and loop on a higher position, remove the chain for maintenance and installation, the chain can not touch the ground or other objects. ⒊Choose a safe position and firmly press the machine with the left hand on the fan casing, the thumb is on the fan casing, do not step on the maintenance tube, and do not kneel under the machine. ⒋ Pull out the start rope gradually until it can't be pulled, and then pull it out quickly and weakly after rebounding. ⒌If the carburetor is properly adjusted, the cutting tool chain cannot rotate at idle speed. ⒍When no-load, the throttle should be pulled to idle speed or small throttle position to avoid the speeding scene; the throttle should be large during the task. ⒎When all the oil in the fuel tank is used up and refueling, restart the manual oil pump at least 5 times.
