Photo 1 for a Allis-Chalmers FT20-24 2000lb Propane Forklift Fork Lift Truck 127" AC 583 Hours

I recently bought the propane version of this forklift and it is a handy little forklift! I was going to do some maintenance on it and change the fluids but It did not come with any books. Do you have any reference manuals for this one or know what kind of tranny fluid and hydraulic oils it likes? From what I’ve found, there doesn’t seem to be a whole lot on the internet about these! Any help would be great, thanks!
