清洗機泵頭應加 30號機油 。30號機油在50℃時的運動粘度為27~33mm?/s，凝點為-10℃，閃點為180℃，適合用于高壓清洗機水泵。使用其他類型的機油，如汽油機機油，可能會導致粘度不適，影響潤滑效果，加速泵體磨損，縮短使用壽命。

　　The pump head of the cleaning machine should be filled with No. 30 engine oil. The kinematic viscosity of No. 30 engine oil at 50 ℃ is 27-33mm ?/s, with a pour point of -10 ℃ and a flash point of 180 ℃. It is suitable for use in high-pressure cleaning machine water pumps. Using other types of engine oil, such as gasoline engine oil, may cause viscosity discomfort, affect lubrication effectiveness, accelerate pump body wear, and shorten service life.

　　對于不同類型的清洗機（如燃汽油或燃柴油的），應選擇相應的機油類型。例如，燃汽油的洗車機應加汽油機機油，而燃柴油的洗車機則應加柴油機機油。此外，油浸式高壓清洗機工作500小時后需要更換密封室機油，機腔機油則每年更換一次，應使用潔凈的5、10號機油；濕式泵在2000小時工作后需要更換鋰基潤滑脂。

　　For different types of cleaning machines (such as those that burn gasoline or diesel), the corresponding oil type should be selected. For example, gasoline powered car wash machines should be equipped with gasoline engine oil, while diesel powered car wash machines should be equipped with diesel engine oil. In addition, after 500 hours of operation, the oil immersed high-pressure cleaning machine needs to replace the sealing chamber oil, and the engine chamber oil should be replaced once a year, using clean No. 5 and No. 10 engine oil; The wet pump needs to replace the lithium based grease after 2000 hours of operation.

　　加注機油時，請確保使用適合您高壓清洗機型號和品牌的高質量機油，并按照說明書上的要求加注適量的機油，避免過多或過少。

　　When adding engine oil, please make sure to use high-quality engine oil that is suitable for your high-pressure washer model and brand, and add an appropriate amount of engine oil according to the instructions, avoiding too much or too little.
