1. propose that the mixable rate of fuel is 20 : 1 to 15: 1 (must mix with high-quality air-cooled type two stroke oil), should use after putting 10%-30% of the diesel oil (kerosene or light oil )in the lubricated oil of saw chain to mix, so as to ensure the suitable density. Its rate should be according to the oil amount that the saw chain gushed out to determine, but should grasp it in 10%-30% of the ranges .
2, rotational speed when the idle speed should be 2500-3000 rotates / min, in the normal atmospheric temperature the rotational speed when the idle speed is 2000 rotates / min. |
