Recommended fuel mix ratios are 20:01 to 15:01 (using high-quality air-cooled two-stroke oil mix), saw chain lubricating oil at 10% to 30% diesel must be added with mixed fuel (natural gas or naphtha) before use to ensure proper concentration. The proportion of saw chain oil spray should be added according to the determination process, but must be in the range of 10% to 30%. The idle speed should be adjusted as follows: 2500~3000 rpm, and at room temperature, the idle speed is 2000 rpm.
Secondly, the idle speed should be adjusted as follows: the speed at idle is 2000 rpm 2500~3000 rpm, and at room temperature. In the motor oil-fuel combination (two-stroke engine oil engine oil), the standard ratio of this ratio is about 25:1. Depending on the use, it may be that if it is not used for a long period of high speed operation, it may be appropriate to increase the concentration and keep it moving forward quickly. If it is used frequently, the concentration should be appropriately reduced and some oil should be placed in the cylinder to ensure proper lubrication of the moving parts. However, be careful to remove the muffler in time, clear the deposition of the exhaust duct, and avoid excessive carbon accumulation in the cylinder, resulting in cylinder damage.
