Garden machinery is a general term. Five main types of machines are used in this industry: lawn mowers, brush cutters, hedge trimmers, chainsaws, and pesticide sprayers.
Using a chainsaw at -30°C
1. The recommended fuel oil mixing ratio is 20:1 to 15:1 (high-quality, air-cooled, two-stroke engine oil must be used). Saw chain lubricant should be mixed with 10% to 30% diesel (kerosene or light oil) to ensure the appropriate concentration. The proportion should be determined based on the amount of oil sprayed from the saw chain, but should be within a range of 10% to 30%.
2. The idle speed should be adjusted to 2500 to 3000 rpm, while the idle speed at room temperature is 2000 rpm.
Fuel Mixture Ratio for Two-Stroke Machinery: Generally, two-stroke machinery fuel is mixed with gasoline engine oil (the engine oil is specifically designed for two-stroke engines). The standard ratio is approximately 25:1 gasoline to engine oil. This ratio varies depending on usage. If high-speed operation is not frequent, the gasoline to engine oil ratio can be increased. If high-speed operation is frequent, the gasoline to engine oil ratio should be reduced, with more engine oil added to ensure proper lubrication of the internal components. However, be sure to remove the muffler and clean out carbon deposits in the exhaust duct to prevent excessive carbon deposits from entering the cylinder and causing seizure. After clearing all vegetation from the site with a sod machine, measure the soil's physical properties and pH, check drainage and irrigation systems, and improve soil compaction with a disc harrow or by hand before reseeding.
