A:  Dear, due to cultural differences, we may have ambiguity in the expression of the product information, for which I am sorry. The "butter" mentioned in the description refers to "gear oil". At present, we are equipped with solid grease when the products leave the factory, so do not need to add it for the time being. Check after 1 year, and if you need to add it, you can add it at the "butter add hole". "Butter/Gear oil" is recommended to use high temperature resistant butter grease 600C 1000 high speed mechanical lubricating oil bearing gear car general grease.

A:  Dear, fill the fuel tank with mixed oil (petrol: Two-stroke engine oil=25:1). Remember to put butter into the gearbox. Pull the starter quickly when starting, do not stop halfway. Start the machine before the gas control switch opens. Press the oil bubble a few times before starting. If oil enters and leaks from the oil line, this is a sign that oil has been supplied. If you start the machine cold, first close the flap and then open it again so you can run the machine normally.
