Confused about what the 4X4 levers do on Hinomoto e2004,2304,2002,2302

[Lowery]

I got a Hinomoto e2004, but I don't know exactly what the three levers on the left side of the seat all do. The 4X4 works, but I have to just move the levers until it engages because the decal/info plate is worn off. Can anyone explain or even send a pic of the decal so I'll know exactly what they do? If you have a pic, post here and I'll send you my phone number to text it to. Thanks
