Hi everyone,
I am unable to identify an old electric / hydraulic forklift, hydraulic steering, 3 stage mast, battery powered.
The electric motor had a very beat up badge that said "Otis"
I have a few pictures of the lift here.

I will need to change the seals on the mast piston but at the moment I don't even know where to start since I can't figure out a name or model.
Any help or ideas is appreciated.
Thanks.
